Fort Worth Roofing: Article About Installng Foil Insulation
When a homeowner wants the energy efficiency provided by a radiant barrier but also needs the thermal resistance of an effective insulating material, weighted foil insulation is a great option. This material can be used in many places around the house, including the walls, ceilings and rafters. Homeowners considering an environmentally friendly upgrade can work with a Fort Worth roofing service to learn about the pros and cons of foil insulation.
Foil wrapped insulation looks like the aluminum foil that is at home in most kitchens. It fully envelops fiberglass or mineral wool to create a two in one package of radiant barrier and insulation. This material is packaged in large rolls that can be trimmed with a utility knife to create a snug fit to insulate places that receive tremendous exposure to heat, such as the roof's rafters, which make up the attic walls. The foil also acts as a vapor barrier, which can help the inside of the attic have better moisture control and less condensation. The lightweight and medium weight varieties are best for use in mild to moderate climates like that of Texas.
To install the foiled insulation, roofers begin by unrolling the insulation and holding it flat against the bottom of the rafters. A staple gun is used to attach the insulation every six inches across and up.

This is done in the space between every rafter. Because each staple creates two tiny holes through the material, the roofers can apply a bead of caulk over the tops of all the staples to seal up any possible points of air intrusion.
If the sheets do not fully cover the space between every rafter, then separate sheets can be overlapped so that their edges cover each other by about two inches. All of the seams should be covered with foil tape to stop air from seeping in or out. This process continues until all of the rafters are covered. If the homeowner wants the attic's flooring to be insulated, a different type of material should be used, such as rolled fiberglass or loose fill.
Any air ducts, vents or plumbing fixtures within the attic can also be insulated with the foil insulation. This can help reduce heat loss and unwanted air exchange through the home's ventilation equipment. Roofers can wrap the foil insulation around the ducts and secure it with metallic foil tape. This tape is made from aluminum and has a strong adhesive that allows it to bond well with the metal on the insulation.
