To fix insulation boards to a wall using this method, start by ensuring the wall is clean and dry. Fix battens around the top and bottom of each wall. Be sure to apply a batten to each corner and around window and door frames. Then, fix the battens vertically around the room at a minimum of 600mm centres. When approaching the window, continue to apply the battens in 600mm minimum centre above and below the opening.
This method can be applied when using:
- Insulation boards
- Insulated plasterboard
- Plasterboard
- Mineral wool
When applying either insulation boards or batts, cut the insulation to size and insert all the way back to the plywood sheathing or masonry surface. Continue until the entire frame has been filled. Ensure the boards are fit flush to the frame with no projections. Use any cut offs to fill gaps left within the frame.
Install a vapour control later over the front of the entire frame – the warm side of the stud work. Lastly, fix plasterboards or insulated plasterboards over the vapour control layer using the required fixings. Ensure the fixings are applied in line with the timer frame and each board is joint at each frame tightly butted together.
Seal any gaps with sealant such as around the perimeter of the floor. Use mesh tape and fill on all boards joins and allow time for the fill to dry. Then go on to apply wall finishings and fixtures.
Note –
Always place the unprinted foil facing towards the masonry wall with the printed side facing outwards towards you as you install.
Take into account all fixtures and fittings when installing timber battens and cutting insulation boards or batts such as lights and sockets.
Ensure all boards or batts are tightly butter together when joined.
When applying plasterboard or insulated plasterboard use lifting wedges on the floor.

Applying PIR insulation boards over timber battens
Insulation boards can be applied over the top of timber battens. Once the battens have been secured to the all edges and corners and at regular vertical intervals around the room, the insulation can be applied. Ensure the battens vertically fitted around the room are in the ideal place for two boards to be joint tightly butted together and fixed at the timber batten.
The boards can then be cut to size if required and fixed to the battens. Ensure when joining boards, they are tightly butted at the centre of the timber battens.
A Must:
When insulating your walls, always consult a building professional or architect to ensure the correct product for your property is being used in the correct method. You may also require approval when insulating a property. This should also be checked and confirmed prior to installing.
