Roof Heat Insulation Foil

You will have to ensure there are good air gaps either side of the foil to get the best performance.

Roof heat insulation foil.

The list of uses includes crawl space radiant floor attic and walls. Reflective insulation is typically made from cardboard or styrofoam sheeting that is covered in a foil reflective material. Radiantguard radiant barrier foil insulation installed in an attics can reduce attic temperatures by up to 30 degrees when stapled with a staple gun to the underside of roof rafters by reflecting up to 97 of the radiant heat that strikes its surface thereby reducing heat transfer from the attic to living spaces resulting in lower utility bills. Reflectix insulation has over 20 energy saving applications for reflectix insulation has over 20 energy saving applications for around the home.

The reason why you need foil insulation when sunlight impinges directly on a metal roof it drives the temperature of the metal as high as 180 degrees fahrenheit. This method also reduces the heat subject to attic mounted ac duct work thereby allowing them to work more efficiently. In the absence of a foil. This variety of insulation is designed to reflect both cold and heat.

This type of insulation may last up to 100 years or more. Foil insulation is worth considering if you have restricted space in your loft or roof space that means regular insulation is not viable.
