Putting Down Thermal On Roof

This type of insulated roof assembly limits thermal bridging through rafters.

Putting down thermal on roof.

A better way to cool the roof is to change its color. Department of energy the surface of a cool roof reflects more sunlight and releases more heat than a so called hot or dark roof. Is roofing felt required. A cool roof is a roof designed to maintain a lower surface temperature in bright sunshine than a traditional roof source.

Work from the perimeter of the attic toward the door or hatch so that you don t trample all over the insulation you just put in. If solarhide is installed under composition shingles with the foil side facing down on the roof deck its an effective thermal barrier that reduces heat gain in to the attic of a home. Felt details for various roof slopes amp. If the roofing job needs to be done immediately due to leaks or wind damage lay a tarp over the damaged section of the roof or install temporary roofing.

This surface will be only 9 f warmer than the outside air on a typical summer afternoon. The plywood was fastened through the rigid foam to the rafters with long screws. A roof with a clean smooth bright white surface can reflect about 85 of incident sunlight and emit thermal radiation with 90 efficiency. Always cover the tops of the ceiling joists to make sure the insulation is deep enough to reach your target r value and to prevent thermal bridging the heat loss that occurs through the wood framing.

To get the best results and to prevent breakage or softening of materials install roofing when the temperature is between 50 and 60 degrees f if at all possible. When solarhide is properly installed in the roof system with the foil side facing an air space it acts as an energy saving radiant barrier. Roofing underlayment roofing felt requirements.
