Energy Efficiency at Every Step

In addition to being physically durable, composite siding is incredibly energy efficient. It insulates your home, wrapping it in a thick shield of protective insulation that keeps in heat when it’s cold and reduces energy loss from heat year-round. With this, you’ll be able to enjoy monthly savings on your utility bills. Plus, once you’re ready to replace your siding far in the future, composite siding is fully recyclable.

Composite Siding FAQS

How long can I expect my composite siding to last?

Composite siding is built to last about 30 years, but may last even longer with proper care and maintenance. It’s also covered by a comprehensive limited lifetime manufacturer’s warranty, including fade protection, which transfers to new owners should you sell your home.

What makes composite siding so durable?

Composite siding is notably tough. It holds up when traditional wood siding simply can’t, such as in persistently wet or otherwise harsh environments. It’s nearly impervious to water with an extremely low water absorption rate, is insect-resistant and never bows, warps or splits.

Does composite siding require maintenance?

Since composite siding is highly resistant to fading or discoloration, you won’t need to do paint touchups or caulking. Rather, a simple rinse with soap and water will do the trick should your siding get dirty. As long as you wash your siding at least once or twice a year, it should hold up well over the years.
