CITY & GUILDS N.V.Q. BRICKWORK says "vapour barriers" and "perforated p.i.r. foam boards"and "perforated foils" are NOT for cavity-walls , or ceilings ; Because they DO NOT BREATHE NO-WHERE NEAR ENOUGH , they severely retard the necessary rapid moisture vapour transpiration from inside the buildings out through the porous substance of both (masonry or timber) walls into the ouside atmosphere of the buildings. The moisture vapour build-up inside the. buildings ( from body breath vapour , cooking steam e.t.c.) is witheld stagnantly within the porous substance of the inner masonry or timber walls ; making uncomfortable chronic dank , over-moist atmosphere , sweating wall conditions inside the buildings.

"B.R.A.C." (building regulations advisory committee (the building advisory team to the U.K. government)) and "N.H.B.C." are misleading the general public into having incorrect builds done. Please URGENTLY ask in person CITY & GUILDS N.V.Q. BRICKWORK for advice.
