While vinyl siding has been a popular choice for many years, one option that homeowners may overlook is insulated vinyl siding. However, thanks to its many advantages, insulated vinyl siding is well worth considering when choosing exterior siding for your home.
One example is CedarMAX® insulated vinyl siding from ProVia®, which combines rigid EPS foam insulation with Super Polymer vinyl siding to deliver an impressive blend of beauty, durability, and energy efficiency.
Four Key Benefits of Insulated Vinyl Siding
Energy Efficiency and Indoor Comfort
A substantial amount of a home’s exterior wall area consists of studs, which are typically not insulated and can allow energy to escape. Insulated vinyl siding can help homeowners improve energy efficiency, reduce heating and cooling costs, and maintain more comfortable indoor temperatures year-round. The added foam insulation in CedarMAX insulated vinyl siding may also help reduce outside noise transmission, which can be especially helpful in areas near busy streets or noisy neighborhoods.
Enhanced Appearance
When investing in new siding, homeowners expect a fresh, polished appearance with smooth, straight surfaces that reflect quality craftsmanship. Insulated vinyl siding helps enhance the look of a home’s exterior by creating a more even surface and minimizing visible wall imperfections.
CedarMAX includes Color Keeper Anti-Fade Protection that keeps colors looking bright for the life of the installation.
Increased Durability
Your siding serves as your home’s first line of defense against harsh weather and everyday impacts, from hailstorms to rocks kicked up by a lawn mower or even a stray baseball.
Placing contoured insulation behind the siding provides additional structural support to the siding, helping the panels resist warping, sagging, and damage from impact and environmental conditions. Additionally, filling the gap eliminates space where pests can nest behind the siding. The insulation is also treated with a safe insecticide to protect it from termites.
ProVia super polymer vinyl siding is formulated from the inside out to provide superior durability and weatherability. The strong molecular chain that begins within our siding makes it pliable, impact resistant, and weather resistant, which results in beautiful siding built to last a lifetime.
Moisture Management
The average household generates several gallons of water vapor each day through activities such as cooking, cleaning, and showering. That moisture must be able to escape the home to help prevent mold and mildew growth.
The insulation used in CedarMAX products is breathable, allowing water vapor to safely pass through and helping protect the home from moisture-related damage.
