What does a radiant barrier cost?
Costs for an attic radiant barrier depend on several factors, including the following:
- Whether purchase includes installation (which increases cost)
- Amount purchased (greater quantities can cost less per square foot)
- Manufacturing method and type of reinforcement
- Presence of other insulation materials
- Marketing methods
- Aspects of supply and demand.
One other condition greatly affects the cost of a radiant barrier system to the homeowner - the individual's knowledge and willingness to do some comparison shopping. A few phone calls and a little research can save you money on most purchases. Radiant barriers are no exception.
Informal surveys show a wide range of material costs ($0.07-$1.00/square foot) and installation costs ($0.10-$1.00/square foot). Remember, foil-faced roof sheathing materials can significantly reduce installation costs in new construction or redecking. The increased costs appear to be due more to marketing practices than to any inherent difference in thermal performance.
In some cases, radiant barriers are included in a package of energy-saving features sold to homeowners. When considering a "package deal," you may want to ask for an itemized list that includes material and installation costs for all measures included. Then shop around to see what each item would cost if you purchased them individually. You may see considerable savings. In addition, you may decide that you want to install the items yourself, including the radiant barrier.
