Internal Insulation of 2 x 2m solid wall bedroom?
Hi
I’m trying to insulate the internal walls of my 2m x 2m box bedroom with single skin brick walls. The room is in the upstairs SE corner of the house, and suffers from damp in the winter. Almost certain it is condensation caused hitting a cold wall.
Anyway, I want to try to eliminate the damp and insulate the house at the same time. Prepared to lose up to 50mm of room with a budget of around £200 for an area of approximately 6m2. Got a few questions:
1. Can anyone suggest some materials with the best real world u-values (not hot box test) for the money & preferably as environmentally friendly in manufacture as possible (not so concerned about embodied energy, more the toxicity in manufacture and breakdown at end of life)
2. And of those materials, is there significant gain going from 20mm to 50mm. Obviously space is at a premium for me.
3. And how can I avoid cold bridging if I want to mount shelves on that wall with screws?
Thanks so much. Hope that’s clear
if you used a starch based foam, it would dissolve, you are left with a organic foam such as styrofoam. It has the highest insulation factor per cm, nearly twice that of a recycled shredded paper.
