The biggest edge our star siding material has over its competition is its built-in insulation. Most insulated siding manufacturers report R-values ranging from R-2.0 to R-5.0, while other materials can have R-values lower than 1.0. And we’re just getting started!
Below are more benefits associated with installing insulated vinyl siding:
- Energy savings. Better insulation means reduced heat loss in winter and reduced heat gain in summer, both of which help lower your energy bills. According to the Vinyl Siding Institute, insulated vinyl siding’s ability to reduce thermal bridging can help your home earn the ENERGY STAR® label (under ENERGY STAR® Qualified Homes Version 3), provided other EPA requirements are also met.
- Moisture performance. Questions about insulated siding’s moisture performance have been raised in the past because of the fact that it isn’t designed to be a water-restrictive barrier. But a study conducted by the Home Innovation Research Labs showed that insulated vinyl siding had some of the lowest sheathing moisture contents recorded because it allowed the material underneath to “breathe”.
- Durability and longevity. The EPS in insulated vinyl siding not only enhances its ability to withstand the elements but also makes it less susceptible to impact-related damage. Some manufacturers report service lives of up to 50 years for insulated siding products.
- Less shrinkage. Insulated vinyl siding contains permanently flexible adhesives that allow for the normal contraction and expansion of PVC. That said, the fact that it has a rigid foam backing also helps prevent the siding from shrinking or expanding to the point of damage in the first place.
- Traditional vinyl siding is considered eco-friendly because it is made from recyclable materials. But insulated siding has an even better cradle-to-grave score. Just like PVC, EPS can be recycled once it has reached the end of its life.
Knowing the benefits of insulated siding is one thing; knowing how to maximize those benefits is another. We’ll cover that in the closing segment of this series.
