Crafted to be perfectly imperfect
Each length of Millboard cladding is the result of a long process of craftsmanship and attention to visual detail. Just like the specially selected Oak timbers used to create the unique moulds, the fine details and natural imperfections in the original timber has  been recreated in the highly durable Millboard product.
From the initial laying of the elastomeric surface, right through to the pouring of the fibre-reinforced resin mineral, we focus on achieving the quality of finish, reflecting the true random and natural characteristics of the original timber. Our passion is to  accurately reproduce the original whilst adding to the benefits of our unique board technology, this is why many of our processes are carried out manually. For example, each piece is hand coloured to establish the authentic wood finish our boards are renowned  for.

Product Suitability

Intended Use
Envello Cladding has been designed for beauty, longevity and ease of installation on residential and low-rise buildings. However, to ensure the best installation and long-term performance, we recommend that a professional tradesperson carriesout the  installation.
Millboard recommend that all cladding designs areapproved by a licensed architect or engineer prior to installation. It is the property owner’s responsibilityto make sure that your plans meet any relevant local building regulations before the installation begins.  Envello Cladding must be supported by a suitable substructure that is in accordance with building regulations.
Envello Cladding is a rainscreen cladding system which can be described as ‘A wall comprising an outer skin of cladding boards and an airtight insulated backing wall separated by a ventilated cavity. Some water may penetrate into the cavity but the rainscreen  cladding is intended to provide protection from direct rain’. Therefore, a well ventilated, free draining cavity should always be included in the detailed design.
It is not recommended to use Envello Cladding in structural applications, as it would need to be fixed to a structural frame of battens.

Limitations
This installation guide is not exhaustive as the responsibility for design lies with the specifier or responsible party for the project, to ensure the final design meets the requirements of the intended application and Building regulations.
For designs outside the scope of this installation guide, specific design must be undertaken by an architect or designer.
If in doubt, we would strongly recommend contacting Millboard pre-design stage to arrive at a suitable, robust, efficient solution and to avoid disappointment.
It is the responsibility of designers, installers, and owners to ensure that the information in this manual is current, by checking with Millboard or referring to our website.
As new technology is introduced or industry standards are altered, Millboard reserves the right to alter existing specifications and remove products without notice.

The use of this manual: does not guarantee acceptance or accreditation of a design, material or building solution by any entity authorised to do so under law; does not mean that a design, material or building solution complies with the building regulation; or  does not absolve the user from complying with any local, or Government legal requirements.

Pre-Installation

Storage and Handling
Millboard Envello Cladding boards should always be stored on a flat surface or level bearers a maximum of 400mm apart and stacked face-to-face, not back-to- face. Both external and internal corner profiles should be fully supported along their length.
When loading and unloading by hand, make sure that both ends are lifted on the edge to avoid permanent deformation and/or damage to the boards.
They should only be lifted off the stack, and not dragged as this could cause abrasion or marking on the surface.
Wear gloves and long sleeves when handling the boards and take care when lifting them. We recommend that two people carry the boards, they should be carried on their side for increased rigidity.
We advise that the cladding planks are stored on site at least 72 hours before installation, to allow the boards to climatize. Only move the pallet if the boards are safely strapped to it.

Millboard cannot be held responsible for damage caused by improper storage and handling of the product.

Tolerances:
There will always be a slight variance in the board’s dimensions due to the fact that we mould from natural oak, and due to the pressure of the moulding process. Despite this, we calibrate the boards to maintain as consistent a profile as possible.
The manufacturing tolerances are: Width: ± 2mm. Length: ± 5mm. Thickness: ± 2mm.
When working with the boards, a level may be required to help keep the boards running level. In order to achieve straight and consistent 5-6mm gapping between boards, it may be necessary to use our Millboard Multi-Spacers during the installation process.

Tools & PPE required
The tools and PPE you will need to install the Millboard Envello Cladding product.
If you are unsure on how to use any tools, please consult the tool’s manufacturer’s user manual.

| Mitre saw/jigsaw/handsaw
Millboard Envello Cladding products can be cut with standard wood cutting tools (i.e. mitre saw,  jigsaw, handsaw).
We recommend using a carbon-tipped saw blade. An aluminium cutting blade should be used for the metal trims.
---|---
| Tool set Standard carpentry tools will be needed to complete the installation, including: tape measure,  a pencil, set square, planer, stanley knife, surform and a drill bit set.
| Spirit level
A spirit level is used to ensure that the battens are upright and the starter trims are level.
| Personal Protective Equipment
When handling Millboard products, it is advised to wear long sleeves and gloves. When cutting  products it is advised to wear a FFP3 dustmask, ear defenders and safety glasses.
| Power drill and 2nd fix nailer
Standard power drill drivers are used to fix the cladding products.  2nd fix nailer can be used with  Stainless Steel brads when the board tongue is taken off.
| Laser level/line
If available, a laser level can be used to ensure the starter trims are installed level.

Cutting
Envello products can be cut with standard wood cutting tools (i.e. mitre saw, jigsaw, handsaw), we recommend a carbon-tipped saw blade. An aluminium cutting blade should be used for the metal trims.
When cutting the boards, wear an FFP3 dust mask, safety glasses, long sleeves and protective gloves. A dust bag or vacuum must be used on mitre saws.
Make sure that the boards are adequately supported when cutting. Boards can be cut face-up or face-down.
When the board is cut, Touch-up Coating should be used if the cut will be visible and exposed to UV.
Dispose of board off-cuts by disposing as general waste or sending to a municipal incinerator for energy replenishment, don’t burn them at home.

Tip:
If there is a breeze/wind when cutting the boards, locate the saw up wind so that excess dust is blown away from the operator & project.

Fire Performance

Millboard Envello Shadow Line+ cladding boards are crafted with fire retardants in the board composition, they have been tested to BS EN 13501-1 and have a classification of D-s3, d0.
In general, Shadow Line+ cladding can be used on low-rise residential and some commercial properties that are below 11m in height and are more than 1m from the boundary.
The responsibility for the cladding’s suitability in the required location is to be determined by a certified building professional (building control, building insurance, fire officer, etc).
Millboard will not be held responsible for incorrect specification, application, or product installation in areas not in accordance with government guidance, in the UK or abroad.
Current guidance should be gained from the government website relating to the geographical project location, England’s building regulation Approved Document B can be found on –

Materials

Colour Characteristics
We go to extraordinary lengths to recreate the look of natural products and therefore intentionally add secondary toning colours. This painstaking process means that there may be variance within the same board or between boards.
Millboard Envello Cladding has been designed to replicatethe natural variances of timber and is manufactured to have tonal variance in the colour.
Buying all the Millboard you need at the same time should help to ensure that the colour is consistent, if you do have multiple batches then it is best to mix the boards, to create an effective, subtle blend.
Antique Oak boasts more tonal variation per individual board than any of the other colours in the Millboard range.
As with all products exposed to the Sunlight (UV), Millboard will naturally weather and tone down over time. Loss of gloss is perfectly normal and will not affect the performance of the products.
Millboard takes great care ensuring the performance of its products maintain the timber effect we seek to portray, and we believe at every stage of its life Millboard truly reflects this more than any other timber alternative product, due to being moulded from real timber and the hand coloured process.
On delivery if you identify any aesthetic or structural defectsplease contact us prior to installation.

Colour tone may vary from batch to batch.
Antique Oak has more variance between boards.

Material Calculator The area (m2 ) is the total wall area to be clad.
m2 = width x height(minus the area of any windows & doors)
Number of boards = m2 x 1.53

Horizontal Installation
Horizontal starter Trims = length of cladding area / 2.5

Perforated Closures will be needed at the top & bottom of the cladding and any windows, and the top of any doors.

Number of perforated closures = [(width of cladding area x 2) + (width of all windows x 2) + (width of all doors)] / 3

Corners, windows & doors
External/Internal Corner Profiles = total linear m for corners / 3
Reveal boards = total linear m around windows and doors / 3.6
Extra perforated closures = Number of corner profiles

Fixings
Number of boxes
30mm fixings = number of cladding boards x 13/250 20mm fixings = number of perforated closures + corner profiles x 14/250
Envello Coloured Head Screws = (number of Reveal boards x 26) + number of cladding boards/100
Touch-up coating = Number of Reveal boards/50

Tip:
Allow extra material for wastage and offcuts.
We would recommend adding at least 10% to the quantities, as complex designs may require more material.

In most instances the cladding boards are fixed using the 30mm fixings through the tongue. Envello Coloured Head Screws may be required for fixing the cladding boards where a fixing through the tongue is not possible, also used for fixings Reveal boards.

Alternative to the Coloured Head Screws:
As an alternative to the Coloured Head screws, 16g stainless steel brads can be used through the face of the board. The brads need to be a minimum of 38mm long, the overall length will depend on the depth of the battens used.
This guide will detail how these can be used in conjunction with the cladding. A small hole may be left where the brad nail has gone through the board surface.

Touch-up Coating

Touch-up used for coating any exposed cuts or edges on the Millboard Envello Cladding boards, corner profiles or Reveal boards.
Additional items that may be required (supplied by others):

• Flashing/drip profiles (around windows/doors/openings or at the bottom of the cladding)
• Fixings for installing the battens on to the structure (suitable type of fixing for the structure and battens used)
• Screws for fixing the battens together (suitable type of screw for the location and battens used)
• Clear high performance sealant adhesive (eg. CT1, Soudall Fix All)
• Polyurethane wood glue (used when mitring the boards)
• Super glue (used when mitring the boards)
• Suitable treated timber battens
• 16g Stainless Steel Brad nails (as an alternative to the coloured head screws)

Preparation

Ventilation
Ventilation for the control of moisture is a key element in the design and construction of cladding. It is a requirement not an option and should not be overlooked. A continuous airflow from bottom to top is vital for long term durability.
As a rainscreen system it assumes that the cladding will always be subject to some moisture penetration, therefore the surface that the battens will be fixed to needs to provide the waterproof finish.
Although a breather membrane is necessary for a timber frame, it may not be required on a masonry cavity wall.
Where the substrate is an existing building with solid walls (i.e. no cavity), to prevent water penetration the wall should be given a waterproof coating or a breathable membrane should be fitted.
Whatever system is used a minimum 19mm open cavity should always be provided behind the cladding and a minimum 10mm continuous gap left at the top and bottom of the system for full ventilation to dissipate any condensation or drainage at the bottom  (see fig. 1).
Consideration regarding insect and rodent invasion should also be considered and a perforated closure should be used to counter these threats where there is the required air gap, whilst still maintaining the required air flow.

Cladding support batten

The time and care taken on setting/fixing the support system right will be reflected in the finished result. Time taken to upright corners and straighten battens on undulating walls will make the installation of the cladding a far easier installation and a superior  finished result. Suitable treated timber battens can be used as the battens for the cladding boards, we would recommend putting a strip of DPC, joist tape or EPDM on to the front of the timber battens that the boards will be attached to.
Batten size requirements:

• Main Cladding batten – minimum size of 25x50mm The maximum support spacing is shown in table 1. For areas of high wind loading exceeding 1.0kN/m², severe weather exposure or where exceptional impact loading requirements are anticipated (i.e.  low-level applications near pedestrian access, schools, leisure facilities etc.) batten support spacing should be reduced to increase the board stiffness, see chart below.
  There should always be battens attached to the wall vertically to allow clear ventilation behind the boards.
  When the cladding is set horizontally the boards would be fixed directly to these battens at the centres shown below.

Table 1:

The batten layout around windows/doors/soffits should be that it allows the continuous airflow behind the boards, a 10mm gap should be left between the underside of the windowsills or soffits and at the head of windows/doors (see fig. 3). The battens up the  side of the window/doors should be flush with the opening; all vertical battens should be upright.
The perforated closure should be used in all areas where there is an opening to the ventilated cavity, to prevent insects entering the cavity (The perforated closures may need to be turned up at each end of the window/door sill). The Millboard Perforated closure  suits batten sizes of 25 or 50mm, if battens different to these sizes are used then perforated closures or flymesh supplied by others should be used.
It is best for the perforated closure to be held between the back of the battens and the wall. This should be taken in to consideration when fixing the battens, alternatively they can be fixed to the front of the battens using the 20mm Accessories fixings.
Determine at what height the cladding is to start at. If it is starting at ground level, it should start at a minimum of 150mm above finished ground level (see fig. 4), or at least 10mm from decking/free-draining surface (see fig. 5). With a laser line or level, mark up
a level line around the building or along the wall that is to be clad. This line will be the bottom of the batten/s.
Battens should be fixed to the structural wall using suitable external grade fixings, for fixing to a timber frame the battens should preferably be fixed into the timber studs of the frame.
The battens should be fixed upright, packers may be needed for these if the wall is undulating. We would recommend the use of fire ventilated cavity barriers where there are opening into the cavity behind the cladding, including at the bottom and tops of windows & doors.

Installation

Before starting to install the main cladding area, it is important to take into consideration how the corners will be detailed (corners of the building and also corners of openings – windows/doors).
Corners of the building
When using the Shadow Line Board the External and Internal Corner Profiles can be used. These allow the boards to butt up to it and hide any potential shrinkage.
If the External Corner profile or Internal Corner profile are being used with the Shadow Line boards on the edges of the buildings, these should be fitted first before the starter trims.
The perforated closure is fitted to the back of the External or Internal Corner profile using the 20mm Accessories fixings at 200mm centres, these are then fixed to the battens on the corner. As shown in fig. 6-8.

Alternatively, the boards can be butted together on an internal corner as shown in fig. 9. The boards can also be mitred to create the external corner, this would also be applicable if the corner is anything other than 90 degrees.
When using the boards horizontally it is best to use the same board around the corner so that the wood grain, colour tone, and profile match.
Ensure to stagger the end points of the boards ie, ½ to ½.
When mitring the boards on a corner, this is done at the same time as installing the cladding boards. The mitred joint detail can be seen in fig. 10.

Tip for mitre joints:
Mitre and dry fit the boards to make sure the joint fits well, apply polyurethane wood glue to the core of the boards and superglue to the surface layer.
Bring the joint together with the surface layer front edge touching together first, then close the back of the joint and drop into place. If any PU glue bubbles out of the joint, wait until it is semi-dry and remove.
Touch-up Coating can be used on any small imperfections on this joint.

Joining Corner Profiles
When joining two Corner Profiles together to make a longer length, these should be joined on a 20 degree scarf joint. They should be joined so that the perforated closure connects both profiles together, dry fit the joint before cutting the profiles to length. The  bottom cut should be painted in Touch-up Coating.

Details around windows & doors
Around windows and door openings we would recommend using the Reveal boards to cover the reveals with the cladding boards butted up to the back of them.
The fascia boards will need to be fixed with the Coloured Head Screws through the face (see fig. 11).
The back edge of the Reveal boards will need to be painted in Touch-up Coating if they will be visible. (see fig. 12)
We’d recommend putting a clear polymer Adhesive/sealant behind the Reveal or cladding boards that are used around the opening before fixing in place.

Please ensure that all all windows and doors are sealed sufficiently before installing cladding around them, ensure that the cladding detailing doesn’t have a detrimental impact on the performance of the windows/door.
Alternatively the boards can be mitred and run back into the window reveal (see fig. 13 & 14)
Another alternative way to finish off around window/door heads is to cut the boards on a 20 degree angled cut and coating the cut with touch-up.
Again the Reveal boards would be used to line the reveals as shown in fig. 15.
Care should be taken not to block the air gap at the top of the reveal and under the sill, leaving a clear 10mm gap.
Any detailing around an opening should allow for airflow to get in to the cavity above the opening.

If brad nails are being used through the board face as an alternative to the Coloured Head screws, there needs to be two brads per batten intersection if the cut-down board is more than 50mm wide and the brads put in at angles. Example shown in fig. 16.
When using brads to fix Cladding and reveal boards around window/door openings, we would recommend the use of a clear polymer adhesive/sealant to help secure the products in place. Example shown in fig. 17.

Please note that brads can only be used as an alternative to the coloured head screws and should not be used through the board tongue instead of the 30mmcladding board fixings. A small hole may be left where the brad nail has gone through the board surface.

Installing Starter Trims
The Starter trims will be fitted to the bottom of the battens.
It is important that these trims are installed level so that the boards running off these trims are level.

These starter trims are fixed to the battens using the 20mm Accessories fixings with the heads countersunk into the trim.

The bottom edge of the board is lower than the bottom of the Starter Trim. Please bear this in mind when setting the height of the Starter Trim.

Fixings
The Millboard Envello Cladding boards should be fixed through the tongue with the 3.5x30mm cladding fixings, with one fixing per batten intersection and two per batten when joining boards.
The fixings should be inserted through the fixing guide groove on the tongue and angled down slightly, the head should sit flush with the surface.
The fixings do not need to be predrilled or countersunk, the boards will allow the head to countersink slightly.

Once the first row of boards have been installed, the second row of boards can be installed ontop of it, with the groove covering the tongue of the previous board.
Check the boards against a level every 4/5th board to ensure that the boards are keeping level, adjust the spacing between the following boards accordingly if needed.
Spacers may be needed in between the boards during installation to keep the boards running level. The Millboard Multi-Spacers can be used to keep a uniform 5/6mm shadow gap between the boards,
When the tongue is taken off the boards to fit around windows/doors, or up to the soffit, 40mm Coloured Head screws or brad nails will need to be used through the board face. Shown in fig. 12-17

Joining boards

When joining boards end-to-end, this should be done where there is a batten behind, so both ends are supported by a batten. It is best to not have the joins all in one line, so that they are spread out across the cladding area.
As the boards are manufactured through a moulding process we recommend that all ends are cut before they’re installed. Dry fit the boards first to make sure they align, using boards that are of appropriate dimensions to ensure a consistent finish.
We recommend that the boards are joined with a 20 degree scarf joint with one overlapping the other, the front face of the cut should be painted in Touch-up Coating (see fig. 20)
As Millboard is made from a resin mineral composition it is stable in comparison to timber or composites based on timber, the amount of movement that is acceptable is up to 0.2%.

Installation Abutting Render
The junction between Envello and render can be done in a number of different ways, however we’d recommend doing the rendering first before fitting the Envello and finishing the render up to a render stop bead rather than directly up to the cladding.
Please ensure that you leave a 3-4mm gap between the render stop and the edge of the cladding/corner profiles.
When running the Shadow Line boards up to render on a wall, the boards can be butted up to the render stop-bead as shown in fig. 21.
The junction between the Shadow Line boards and render on a corner can be done utilising Corner Profiles or Reveal boards (see fig. 22).
When installing cladding above render, it is best to install a flashing detail which goes up behind the cladding battens and protrudes further than the render. This is to allow rain water to drip off the flashing detail (see fig. 23).

After care

Cleaning
When installing the boards as part of a wider project, we would strongly recommend they are stored away from cement dust or potential debris to minimise lasting damage or marking.
If the boards become dirty during installation, they should be cleaned as soon as possible using warm soapy water and a brush or pressure washer.
Start cleaning at the top of the cladding and work downwards along the grain. It is best to use a brush with an extendable handle to clean the boards.
Pressure washers can be used on Millboard Envello Cladding, with a PSI of no greater than 2000. A fan tip should be used with a 40 to 60 degree spread, keeping the head 250-300mm away from the surface. Test in an inconspicuous area first – direct, prolonged contact could damage the surface of the boards.
Take extra care when using a pressure washer around windows, doors and cut ends of boards.
Stubborn marks may be removed with a range of different cleaners depending on the mark.
