One of the most effective products on the market today that prevents heat from entering your attic is radiant barrier. Depending on the product you use, it blocks approximately 70-90% of UV rays. This reduction in blocked heat can translate into a more comfortable home for you as well as savings on your utility bill.
There are a number of options to choose from when purchasing radiant barrier. Much of it depends on the condition of your roof. Read on!
Plywood sheathing – Homes with wood shingles or shakes generally do not have plywood decking. When it is time to replace the roof and install composition shingles it is necessary to deck the rafter with plywood in order to provide a nailing surface for the shingles. This is the perfect time to install radiant barrier that is applied to the decking. You are already incurring the cost of the plywood and the upgrade to radiant barrier is well worth the investment.
• Rolled – For a home that needs a new roof but already has plywood decking there is a product made by Heat Barrier Systems calls Polaralum Thermal Barrier. It is sold by the roll and is installed on top of the plywood and can be used in place of roofing felt. If you are replacing your siding this product can also be used on the studs behind the siding. (Note this radiant barrier is perforated in order to allow for ventilation.)
• Important Note: Decking and Polaralum have tested to block 90-92% of UV rays.
• Spray-on – If you do not foresee a new roof in the near future but need some relief, a spray-on product can be applied to the attic side of your decking. Spray-on products have been tested to block 70-72% of the UV rays. They also cost less than plywood sheathing or roll products.
If you are thinking about putting your home on the market, radiant barrier can be a strong selling point. Home purchasers are reluctant to purchase a home with a utility bill the size of a second mortgage. All in all, you cannot go wrong with radiant barrier!
