What This Session Covers
Upgrading the roof of an older home can easily go wrong if moisture gets trapped. This session explains how traditional Irish roofs were built, what typically causes problems, and how to insulate them safely using breathable, natural materials.
We break down the practical differences between breathable and non-breathable roof systems, and show how to combine woodfibre insulation, breathable membranes and vapour control layers to keep your home warm, dry and healthy.
By the end, you’ll understand how to insulate your roof without creating condensation issues, and how to make choices that protect the structure for the long term.
