Questions & Answers


Is this suitable to lay underneath insulation in attic, renovating 1960's house with poor loft insulation. Is it a vapour barrier or vapour control item? Also what is the advantage of control vs barrier in a loft?


A vapour barrier and a vapour control layer are essentially the same thing, their main purpose is to be used as an airtight layer on the warm side of the roof to minimise the risk of condensation, they will not much provide much in the way of thermal benefit so is best combined with insulation to acheive effect.
