One of the best techniques that Bergen County roofing experts use for making a house more energy efficient, comfortable and environmentally friendly is to combine the proper level of insulation with a radiant barrier. Although a well insulated attic on its own is excellent, combining the reflectivity of the radiant barrier offers some additional merits to the homeowners. Before having all of these materials installed, there are a few things that property owners should know about their effectiveness and functionality.
The best way to combine fiberglass insulation and a radiant barrier is to install both of them at once. This can be done when a house is built, during a roof replacement project or a home renovation. All of the work takes place within the attic, so rain and wind will not affect the project's timeline. For the comfort of the work crew, it is best to do the project on a day that is cloudy and mild.
If fiberglass insulation is already in place, the roofers will measure it to ensure that it meets the U.S. Department of Energy's recommended R value. If it doesn't, the roofers can add more of the rolls. Once there is sufficient attic insulation in place between the rafters, then the radiant barrier can be installed right on top of the fiberglass.

The roofers simply use a staple gun and staples to attach the barrier to the insulation's paper flanges. All of the insulation and the exposed rafters should be covered with the foiled barrier for the best results.
If there is no insulation within the attic, then property owners will have a few additional choices. The roofers can install fiberglass batts that already have a foil side on them, or they can use a separate radiant barrier. When separate insulation and barriers are used, the insulation should be installed first. Once it is in place, the barrier can then be put on top of it. The thin, fragile barrier requires careful handling so it does not tear or shred at its edges.
When one piece of the barrier runs out, the roofers will add a new section, allowing for a minimum 1 inch overlap. Once the entire barrier is attached to the insulation with staples, the workers will go back and use a roll of adhesive metallic foil tape to seal up the seams. This tape can also be used to attach the barrier to obstructions like perimeters of vents and around air ducts.
