Roof Insulation To Keep Heat Out

Foil insulation is ideal for hot weather and is mostly used in roofs and walls.

Roof insulation to keep heat out.

The more insulation you have between the actual living area and the roof the better. I also prefer full width insulation baffles for the underside of the roof sheathing. In most cases ceiling insulation is installed between the joists see insulation installation. It s designed to reflect heat radiation but also comes combined with bulk insulation like glass wool or rock wool batts to create a composite type insulation which insulates against heat transfer through convection and conduction too.

All of the heat that strikes your roof is trapped in your roof space and its movement into your home is slowed. Not sure sierraeast s recommendation would work if your roof is sagging due to inadequate support. Here s how it works. It will work as a barrier to keep the heat away from the home in the summer while keeping the warmth inside in the winter.

By sealing off the eaves and encapsulating the attic roof deck this allows the hot air from outside of the home to stay outside and the air conditioning to work less by staying cool in the attic space. In summer a similar concept applies. It prevents heat from passing through. Coupling with fiberglass insulation between the rafters should significantly reduce the amount of heat coming through the roof.

In winter your roof insulation blocks the cold air keeping your home warmer and giving your heater less work to do. Ceiling insulation products and materials become the heat flow barrier between your roof tiles and ceiling boards. If your home does get heated during the summer months look into adding more insulation in the attic or within the roof trusses. Install insulation under the roofing material to reduce radiant heat gain.
