How are insulation boards installed in wall applications?

Insulated plasterboard can be installed using the dot and dab method however the most used method of installing insulated plasterboards is to mechanically fix the boards onto timber battens. See below.

Step 1:

Fix the timber battens at the floor and ceiling around the entire room. Then go on to fix the battens around door and window openings and vertically around the room at 600mm apart. Fix the battens 75mm from its end. Every batten should have a minimum depth of 25mm and width of 47mm. Back the battens with a damp proof course (DPC).

Step 2:

Cut the insulation boards to the required size. The boards should be cut 5mm short of floor to ceiling height.

Step 3:

Fit the insulated plasterboard, at sheet joins, lap them over the timber battens so the two sheets meet at the centre point of the batten. Tightly but the boards with fixings no less than 10mm from the edges of the board. Fix drywall screws at 300mm centres. Or large headed galvanised clout nails at 150mm centres. Make sure the fixings do not go all the way through the timber. A penetration through the board and 22.5mm into the timber frame should be enough.

Step 4:

Seal the perimeter of the insulated plasterboard with flexible sealant or the equivalent product. Go on to complete the wall using plaster and adhesive compound. Add paint and keep the walls plain or add a bolder touch to suit your taste with wallpaper.

Does Insulated Plasterboard cause dampness?

When Insulated Plasterboard is installed correctly and care is taken to ensure all gaps between and behind the insulation boards are filled, this will prevent dampness from occurring. When gaps are filled to high standards this prevents moisture from migrating from the warm air in the room to the colder solid wall behind the insulation. If the Insulated Plasterboards are not correctly installed and gaps occur, this will present a condensation risk. When boards are installed, care should be taken to ensure the relevant wall is free of mould and rot and if they should occur they are treated before installing the boards. Installing insulation materials over mould or rot can cause the problem to worsen and in extreme cases, damage to the structure of the building.

What size do I need?

The size you need will depend on the space being insulated. Thicker insulation is always the best option to achieve the best thermal conductivity possible however a thinned board will also improve the thermal conductivity. This decision is really based on how much space you want to save, and if the board meets the building regulations.
