Advice Needed - Cold Bridge Behind Full Fill PIR Insulation
ADVICE NEEDED PLEASE..!
The walls on our detached 3 bed new build are made up of (from in to out): 100mm medium dense blocks, 100mm cavity with full fill PIR insulation (cavities are more like 115/120mm wide), 100mm medium dense blocks (no thermalite has been used). We are at block course 14 of 23, so already towards the top of the house. The problem is the insulation has not been fitted tight to the inner leaf. We have a 10mm gap behind the insulation to the inner leaf in numerous areas. T
what a pity. you really have my sympathy.
@ETC is unfortunately right about this, can you elaborate on why it is not an option? It can be psychologically extremely difficult to undo work to put it right but it’s the proper, and often the cheapest thing to do.
Cold bridging is probably the wrong term here. “Thermal looping“ is a better one,
A quick google turned this up. There are other sources of info.
