Iv asked my builder for a quote to do wall insulation as it’s not included in the build price and we are facing west and I’m worried about heat gain. The only option they have provided is reflecta
break cavity wall foil.
Does anyone know this product? Is it any good? Is it worth paying extra for this product? They said they dont do wall batts. Iv read online wall foil should help reflect heat away from the internal brick (double brick wall) any info or advice would be greatly appreciated. Iv also asked about double glazing and they said they can get a quote for comfort plus 6.38mm double glazing.
Thanks!
