Vaulted ceiling insulation building regs.

1 foot 304 8 mm. Finally traditional fiberglass insulation works well in cathedral ceilings although a 2 inch breathing space between the insulation and the roof sheathing must be included. The limiting u value the maximise u value which cannot be exceeded required under current building regulations for the roof is 0 20w m. Building regulations for insulating a roof heat rises and therefore the building regulations requirements for heat loss through roofs are more stringent than those for walls.

R 30 ceiling insulation may be used in place of r 37 if the insulation achieves the full r value over the entire ceiling area i e not compressed over exterior. Building regs suggest i need a structural calculation for that do you guys agree. Building regulations standards set the levels of thermal insulation required when carrying out building work either for new build or refurbishment projects. Ie what size straps masonry hangers etc.

If you decide to construct a vaulted ceiling check with your local office regarding building permits and consult with an experienced structural engineer to ensure safety. Insulation can be placed between the ceiling joists. Again the thickness will vary depending on the material you choose to use. And how else would i make the roof supported if im going for a vaulted ceiling without cross joists.
