Alpine Heating and Cooling in Minneapolis – What Is an Attic Radiant Barrier?

Attic radiant barriers consist of a reflective foil bonded to stiff material to give the barrier strength. A properly installed attic radiant barrier will lower the heating and cooling coasts of a building. The savings vary depending on the location of the structure and the type of heating and cooling system used to condition the space. Buildings with heating, ventilation and air conditioning ducts running through an attic space receive higher savings than homes without duct or ductwork running in a basement. Preparation, barrier selection and installation will ensure a building owner receives the most protection from raising utility costs.

Mini Split Heating and Cooling in Minneapolis – Attic Radiant Barrier.

Before an attic radiant barrier is installed on the roof sheathing of a structure, all dust, dirt and installed insulation must be removed from the area to ensure the barrier remains fastened to the sheathing. Loose debris will decrease the bond between the adhesive and the surface of the sheathing. A combination of rags, brushed and a wet/dry vacuum is commonly used to clean the surface of the sheathing prior to the installation of an attic radiant barrier. Selecting the proper radiant barrier to install on the cleaned sheathing will provide the most protection against heat intrusion into the structure being protected.

Split System Heating and Cooling in Minneapolis – Sealing an Attic.

Sealing an attic reduces the amount of air and heat moving from the outside to the inside of a structure. Silicone, latex and acrylic caulks all provide the necessary sealing required to reduce heating and cooling costs of a structure.

The caulking can be applied before or after the installation of a reflective foil-type attic radiant barrier, but the sealant must be applied before spraying radiant barriers. Proper application of sealant and attic radiant barriers will provide the most protection against rising energy costs and heat damage.
