Hi there,
We have an existing single skin brick extension that houses our kitchen.
Both the kitchen units and the roof are very tired and we are taking the opportunity to extend the extension when we replace the kitchen.
Amazingly the existing walls have NO insulation (built in the 80s) and due to the position of two existing openings we don't have the room to lose the width required to build a cavity. The existing walls are rendered externally and they appear in great condition, i.e. no cracks internally or externally.
Therefore, my proposal is to line the walls with Celotex and use frame fixings to fix timber battens on top of the Celotex and through to the brick wall. I've used this method before to convert my Dad's single skin garage into a studio and it worked fine.
My only concern is whether this wall build-up is going to take the weight of new kitchen wall cabinets, 900mm high ones at that. I propose to use the continuous strip hanging rails to spread the load but wonder whether I need to introduce a 150mm strip or full wall lining of ply over the timber battens in addition to the p/board.
Any suggestions would be greatly appreciated.
