There are two main methods of installing radiant barrier: stapling it up to the rafters or laying it on the attic floor. Installation methods are not based solely on where you are located; there are several factors that determine the best installation method for your home. Every home is different, so while there are general recommendations for certain climates, sometimes one method is best for a particular home.

Choose the Best Installation Method

Two Most Common Installation Methods

Standard Staple Up Method (Warm Climates)

The Staple Up (also known as the Open-Ridge) method is the standard method used most often in WARM or HOT climates. This is especially true if your main objective is to reduce summer heat gain or if you have ductwork in the attic.


Over Insulation Method (Cold or Mixed Climates)

Create a green energy barrier by laying the radiant barrier foil out OVER the existing insulation on the attic floor. This method keeps heat out in summer and heat in during winter months, making it ideal for year-round benefit.
