Kingspan K17 Insulation Plasterboard Installation Guide

Kingspan K17 Insulation Plasterboard

Product Information

The Kingspan Kooltherm K17 Insulation is a high-performance rigid thermoset phenolic insulation. It features a fibre-free, closed cell insulation core and provides 3-in-1 insulation, dry-lining, and vapour control. The insulation is also available in a range of other selected lining materials. It has a Group 1 NCC fire classification and is resistant to the passage of water vapour. The insulation is easy to handle and install and is ideal for both new build and refurbishment projects. It is manufactured in Australia without the use of CFC or HCFC and has zero ODP (Ozone Depletion Potential) and low GWP (Global Warming Potential). The product is compliant with AS/NZS 4859.1:2018.

Typical Constructions and Total R-values

The Kingspan Kooltherm K17 Insulation can be adhesive bonded to concrete walls (150 mm) or masonry block walls (140 mm). The product thickness determines the heat flow in and out, including the plasterboard. The table below shows the total R-values for different product thicknesses.

Product Usage Instructions

To install the Kingspan Kooltherm K17 Insulation, follow these steps:

1. Ensure that the concrete or masonry block wall is clean and free from any debris.
2. If necessary, cut the insulation panels to fit the dimensions of the wall.
3. Apply adhesive bonding to the back of the insulation panels.
4. Press the insulation panels firmly against the wall, ensuring good adhesion.
5. If required, attach the insulated plasterboard to the front of the insulation panels using adhesive bonding.
6. Repeat the above steps for each panel until the entire surface is covered.
7. If necessary, trim the plasterboard to fit around any obstacles or openings.
8. Ensure that all joints and edges are properly sealed to prevent air leakage.

Dry Wall Plasterboard
Kingspan Kooltherm® K17 Insulated Plasterboard can be applied utilising a variety of traditional or modern dry-lining techniques, to dry and structurally sound walls. These include the construction adhesive bonding method. The particular system employed will depend on the construction or design of the wall to which Kingspan Kooltherm® K17 Insulated Plasterboard is to be fixed. If an acceptable adhesive bond cannot be achieved due to the wall surface, consideration should be given to a mechanically fixed option. The tapered edge to the plasterboard enables a flat seamless surface equal to traditional plaster finishes after the correct jointing procedures as per plasterboard manufacturer’s recommendation have been completed.

Construction Adhesive Bonding
This method is for application to brick, block or concrete masonry cavity walls which are free from moisture penetration.

1. Ensure that the wall surface to be bonded to is free from oil, grease, paint, release agent, or any contaminate that may affect the bond of the adhesive to the wall.
2. Gun apply a continuous blob of construction adhesive around perimeter wall and ceiling junctions, and around any openings, such as windows and doors, in order to provide a seal.
3. Gun apply blobs of construction adhesive to the wall or the back of the board approximately 25 mm in diameter (single squeeze), at 300 mm centres in both directions or to specific adhesive manufacturer’s instructions. Ensure that the blobs adjacent to a board joint are approximately 25 mm in from the edge to avoid bridging the joint.
4. Tap the board back firmly using a straightedge, ensuring that the vertical edge is plumb.
5. Continue dry lining in the same manner.
6. Appropriate mechanical fixings are recommended to complement the adhesive bond. Apply 2 per board after the adhesive has set, positioned 15 mm in from the board edge and at mid height with a nominal 25 mm embedment into the wall. (Refer to fixing manufacturer instructions for more information).
7. For boards 3 m and longer 4 fixings should be used.
8. When using the Kingspan Kooltherm K17+ Insulated Lining Board Range, use a minimum of 6 mechanical fixings per board. Positioned 15 mm in from the edge, at the top, middle and bottom of the board.
9. It is recommended that mechanical fixings are positioned in the tapered edge of the boards so that they are covered when the board is finished, (e.g. joints taped and skim coating) at mid height. Boards should be fitted tight to the ceiling/joists.

Mechanical Fixing
This method is for application to brick, block or concrete masonry cavity walls which are free from moisture penetration and an adhesive bond is not suitable or heavy surface linings such as tiles are to be applied.

1. Ensure the wall is true and free from projections which may prevent the board from sitting flat.
2. Predrill into the wall substrate using a masonry bit.
3. Insert a masonry anchor with a minimum of 25 mm embedment into the structure.
4. Fixings should be driven straight, with the heads embedded just below the surface of the plasterboard. Care should be taken not to overdrive screws.
5. Screws should be fixed at 600 mm max. horizontal centres and 300 mm max. vertical centres.

Corner & Skirting Details

• For internal and external corners, sheets should be cut and rebated to allow a plasterboard / plasterboard joint at the angle. Ensure sheets are lightly butted and air gaps minimised to reduce the risk of cold bridging. (See Figures 7 & 8).

• A 5 mm packer should be used at the base of the wall to provide a level surface from which to build up the boards. Replace with a flexible urethane / acoustic sealant prior to skirting being fitted (see Figure 8).

Window / Door Reveals & Soffit Details
A thinner sheet of Kingspan Kooltherm® K17 Insulated Plasterboard at reveals may be necessary (see Figure 9) to account for opening frames. Where adhesives are employed at openings, strips of insulated plasterboard should be temporarily supported.

General

• Cutting

  • Cutting should be carried out either by using a fine toothed saw, or by using a sharp knife to cut through the insulation and paper backing of the plasterboard, then snapping the board face down over a straight edge and cutting the paper facing of the plasterboard 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. Figure 10.

• Board Orientation
  The Kingspan Kooltherm® K17 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 in accordance with AS/NZS 3008.1 series.
  • Ensure excess insulation is not removed to minimise thermal weaknesses.

• Packaging
  According to quantity, the boards are supplied in packs, labelled 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 spilt 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.
  • Installation must be in accordance with AS 3999 Bulk Thermal Insulation Installation and AS 3000 Electrical Installations (Wiring Rules).
