Product Usage Instructions

To install the Kingspan Kooltherm K18 Insulation, follow the typical constructions and total R-values provided in the user manual. The insulation can be mechanically fixed to timber framing or the internal side of a steel frame with close-jointed cladding. For timber framing, ensure proper fixing to the timber studs or rafters using appropriate fasteners.

When installing the insulation, make sure to maintain a clear cavity to resist moisture penetration. The K18 Insulation is also resistant to the passage of water vapor, which helps to maintain the integrity of the insulation over time.

For tiled roofs with timber rafters, the insulation can be mechanically fixed to the timber rafters using appropriate fixings. Ensure proper coverage with the sarking or breather membrane before installing lightweight cladding.

Refer to Figure 1, Figure 2, Figure 3, and Figure 4 in the user manual for visual representations of the recommended installations.

When determining the total R-value calculations, refer to the NCC 2019 guidelines for the specific building class and volume. The user manual provides a table with different product thicknesses and corresponding heat flow values for both heat flow in and heat flow out.

Always follow the recommended installation practices and consult with a professional if needed to ensure proper installation and optimal performance of the Kingspan Kooltherm K18 Insulation.

Installation Instructions

Dry Wall Plasterboard
Kingspan Kooltherm® K18 Insulated Plasterboard can be applied utilizing a variety of traditional or modern dry-lining techniques, to dry and structurally sound walls. These include traditional fixing to metal or timber frames, metal furring systems, or vertical timber batten systems. The particular system employed will depend on the construction or design of the wall to which Kingspan Kooltherm® K18 Insulated Plasterboard is to be fixed. The tapered edge to the plasterboard enables a flat seamless surface equal to traditional plaster finishes after the correct jointing procedures as per the plasterboard manufacturer’s recommendation have been completed.

Kingspan Kooltherm® K18 Insulated Plasterboard must be installed per AS/NZS 2589:2007 Gypsum linings – Application and finishing.

Mechanical Fixing to Metal or Timber Frames/Metal Stud and Track/Battens
This method may be used on timber frames, metal studs, and track constructions or on any dry masonry wall that will support and retain the battens and associated fixings.

1. Place framing/battens at a maximum of 600 mm centers and positioned horizontally at floor and ceiling level / horizontal joints to support the Kingspan Kooltherm® K18 Insulated Plasterboard.
2. Ensure the framing/ battens will be wide enough to offer a minimum of 20 mm support to all edges of the board.
3. Use plasterboard screws long enough to allow for a minimum 20 mm embedment into the stud or suitable galvanized plasterboard nails, which should be placed at 200 mm centers and not less than 10 mm from the edges of the board along the line of the studs.
4. Drive fixings straight and embed heads just below the surface of the board. Care should be taken not to overdrive the fixing.
5. Screws used for plasterboard fixing must comply with AS 3566.2:2002 self-drilling screws complying with the building and construction industry corrosion resistance requirements.

Mechanical Fixing to Metal Furring Systems

Figure 8 Side elevation – Lightweight cladded stud wall with Kingspan Kooltherm® K18 Insulated Plasterboard

Kingspan Kooltherm® K18 Insulated Plasterboard can be fixed by the use of proprietary metal support systems to brick, block, stone, or concrete walls. The metal frame should be fixed to the masonry or concrete walls.

1. Provide a true and level base for the Kingspan Kooltherm® K18 Insulated Plasterboard by fixing the metal frame to the masonry or concrete wall under the manufacturer’s instructions.
2. Set the frame vertically at a maximum of 600 mm centers to coincide with the board joints and the midpoint of the board.
3. Fix the Kingspan Kooltherm® K18 Insulated Plasterboard to each metal framing section with self-drilling plasterboard screws at 200 mm centers.
4. Drive fixings straight and embed heads just below the surface of the board. Care should be taken not to overdrive the fixing.

Mechanical Fixing to Timber Joists or Rafters

Kingspan Kooltherm® K18 Insulated Plasterboard may be used to line ceilings or infill where an exposed rafter is desired. Installation is similar to that of a standard plasterboard.

1. A minimum of 20 mm bearing onto the timbers must be offered at each sheet joint.
2. Sheets should be fixed using either drywall screws or suitable galvanized plasterboard nails located at 150 mm centers.
3. Ensure fixings are located no less than 10 mm from the edges of the sheet.
4. Fixings should be long enough to allow a minimum embedment of 20 mm into the timber.
5. Fixings should be driven straight with the heads embedded just below the surface of the sheet. Care should be taken not to overdrive the fixing.

General Requirements

Cutting

• Cutting should be carried out either by using a fine-toothed saw, or by scoring with a sharp knife through the insulation and scoring the back of the plasterboard itself, then snapping the board over a straight edge and then cutting the facing on the other side. Ensure accurate trimming to achieve close-butting joints and continuity of insulation. Sheets being cut should be adequately supported to prevent breakage.
• When using a fine-toothed saw, ensure edges are supported to avoid excessive vibration.
• When multiple cuts on a board are required, such as around windows, consider segmenting the board into smaller sections to prevent excessive movement of the board.

Board Orientation
The Kingspan Kooltherm® K18 Insulated Plasterboard can be laid in a horizontal or vertical orientation to best suit the room configuration.
Services

• Where electrical and plumbing services are not surface mounted or chased into the structure, carefully recess the back of the insulation to accommodate the services.
• To ensure an appropriate rate of heat dissipation from cables, the current-carrying capacity of any electrical services partially surrounded by thermal insulation should be determined following the AS/NZS 3008.1 series.
• Ensure excess insulation is not removed to minimize thermal weaknesses.

Packaging
According to quantity, the boards are supplied in packs, labeled, and shrink- wrapped in polythene.

Handling and Storage

Storage
The packaging of Kingspan Kooltherm® should not be considered adequate for long-term outdoor protection. Ideally, boards should
be stored inside a building. If, however, outdoor storage cannot be avoided then the boards should be stacked clear of the ground and covered with an opaque polythene sheet or weatherproof tarpaulin. Boards that have been allowed to get wet should not be used.

Resistance to Solvents
The insulation core is resistant to short–term contact with petrol
and with most dilute acids, alkalis, and mineral oils. However, it is recommended that any spills be cleaned off fully before the boards are installed. Ensure that safe methods of cleaning are used, as recommended by suppliers of the spilled liquid. The insulation core is not resistant to some solvent-based adhesive systems, particularly those containing methyl ethyl ketone. Adhesives containing such solvents should not be used in association with this product. Damaged boards or boards that have been in contact with harsh solvents or acids should not be used.

OH & S
Kingspan Insulation products are chemically inert and safe to use. A Product Safety Information sheet is available from Kingspan Insulation Pty Ltd.
Please note that the reflective surfaces on this product are designed to enhance their thermal performance. As such, they will reflect light as well as heat, including ultraviolet light. Therefore, if these boards are being installed during bright or sunny weather, it is advisable to wear UV protective sunglasses or goggles, and if the skin is exposed for
a significant period, to protect bare skin with a UV block sun cream.

Foil facings are conductive to electricity – avoid contact with un- insulated electrical cables and fittings.
Installation must be under AS 3999 Bulk Thermal Insulation Installation and AS 3000 Electrical Installations (Wiring Rules).
