Insulation of the attic by the under-roof

Roof sections are the main source of heat loss in a home. The simplest way to isolate them is to treat them on the underside, that is to say from inside the attic.

A double layer of glass wool is then laid, the first between rafters, without a vapor barrier, the second with a vapor barrier, hooked onto suspension lines, which are themselves fixed to the frame. These will allow the installation of metal furs on which will be screwed the drywall after interposition of an airtight membrane.

Warning: do not start this kind of pose unless you feel the skills. If not, call a professional installer.
