My aim is to insulate the wall as it's cold. I've used the polystyrene wallpapers before and the insulation is surprisingly good. I'm wary of using it on the stair wall though because it could easily get dented so I am looking for an alternative.
Hi,
I'm topping up existing loft insulation. We have 12 downlighters. The loft insulation has been cut back around them, presumably to allow heat to disperse. I don't think that it would be practical to do the same with the top up insulation.
Do I need to use those downlight protectors or is...
