CedarMAX Insulated Vinyl Siding (Outstanding Performance Inside and Out)

CedarMAX insulated vinyl siding combines rigid foam EPS insulation¹ with our Super Polymer vinyl siding, providing an impressive combination of beauty, durability and energy efficiency.
Showcasing an authentic cedar woodgrain texture, CedarMAX siding offers a wide array of color options and four unique profiles so that you can easily choose colors that coordinate with your home’s exterior.
CedarMAX traditional lap siding and dutch lap siding profiles (Single 7″, Double 6″ and Triple 4″ Dutch Lap) can be used to clad an entire house. Or, they can be combined with CedarMAX Board and Batten vertical siding for a contrasting look. Any of the CedarMAX profiles pair well with ProVia’s manufactured stone or Harbor Mill™ Shake and Shingle.
¹Progressive Foam Technologies, Inc’s Fullback Insulation
Impact Resistance
Our Super Polymer formulation is engineered with high-grade impact modifiers that act as shock absorbers.
These impact modifiers add strength and durability, providing protection from the unexpected—whether it’s an accidental strike from your child’s baseball or a stone projected from your lawn mower. In addition, the rigid EPS foam backing on CedarMAX provides five times greater impact resistance than non-insulated siding for even greater peace of mind.
Continuous Insulation
Tested and proven to increase the R-value² of an exterior wall, CedarMAX foam backed vinyl siding is one of the most energy-efficient exterior claddings on the market. That’s because unlike most wall insulation that resides only between studs, CedarMAX insulated siding covers the entire exterior wall, providing continuous insulation over studs that normally wouldn’t be insulated.
Wall studs comprise up to 25% of a wall’s surface on an average home, and having them uninsulated equivalates to having one entire wall with no insulation at all!
Sound Reduction
The added foam insulation in CedarMAX insulated vinyl siding may help reduce outside noise transmission by as much as 39%, according to a study that Progressive Foam Technologies had conducted by a third-party test laboratory.
Sometimes you want to open your windows and listen to certain noises outside, whether it’s the gentle sound of the breeze blowing through the trees or the cheerful melody of birds announcing the arrival of spring. Other times, you’d prefer to block out certain sounds, such as your neighbor’s chainsaw, a passing motorcycle, or a nearby plane taking off.

ProVia Stone Siding
HANDCRAFTED MOLDS. REALISTIC TEXTURES.
Manufactured stone veneer adds elegance and charm to a home’s exterior and interior, calling to mind rustic country cottages and stately manors. ProVia manufactured stone is artfully crafted to replicate the rugged textures, shadow lines, and coloring of authentic quarried stone. Our process includes placing a mixture of high-quality aggregates, cement, iron oxides and pigment into handcrafted molds to replicate the look of real stone from unique geographic regions, reproducing undercuts, subtle textures, and natural hues.
ProVia manufactured stone veneer is unique, because each stone in every profile and palette starts with the expertise of a trained stone mason. Natural stones are selected and sculpted by true professional masons, and used to create a realistic, handcrafted master mold. Real quarried stone molding, not computer modeling or CAD imaging, results in a near-perfect replica with all of the depth, character, texture and nuance of authentic stone. Edges, corners, reliefs and faces are expertly chiseled by hand, ensuring that even the smallest detail is accurate.
ProVia stone is not a typical manufactured stone veneer or panelized product. Our molds are created by experienced stone masons who cut and chisel individual stones by hand, ensuring the molds produce the most authentic, natural looking stone on the market.
Each stone has a flat back for easier installation and fewer cuts on the jobsite.
