How to fix fibreglass or insulation boards to inner leaf
Anonymous user 23/02/2024 - 3.20 PM
In the process of blocking up a doorway, either side of the existing opening there is a insulation missing from the cavity wall one side is 2m worth missing. What is the best method for installing boards so that they fixed to the inner leaf? Can I use glue to stick the boards? I would use loose fill but the material seems to be really expensive and difficult to get a hold of.

Insulated plasterboard is attached to the wall either with dabs of plasterboard adhesive or screwed or nailed to battens of wood treated with preservative. The battens method avoids the joint cracking which is common with the adhesive method, but on the downside the battens waste a bit of space and could rot if the vapour barrier is poor.
