Two vinyl siding panels can look identical on the day they go up. Ten Midwest summers and winters later, the difference shows: one is still flat, flexible and true to color; the other is chalky, faded, brittle or wavy. That gap comes from what the panel is made of and how it attaches to the wall. Here is what ProVia builds into its siding, in plain language.
What's in the Panel
- Tri-Pigment Reflective Technology uses heat-resistant inorganic pigments that reflect solar heat away from the wall, so deep colors stay true and the panel does not soak up heat.
- Weather Barrier Shield concentrates anti-weathering ingredients at the surface to resist the slow breakdown that dulls siding.
- SPX-2000 UV Blocker protects the polymer against ultraviolet light.
- Color Keeper™ Anti-Fade Protection helps hold the color for the life of the siding.
- Impact modifiers (butyl and acrylic) act as shock absorbers, so the panel flexes instead of cracking when hail, a ball or a stone from a mower hits it.
How It Attaches
- High-tension structural return and nail depth guide for a more rigid connection to the wall, and to keep nails from being driven too tight.
- Double-ply nailing hem for twice the tear resistance and better high-wind performance.
- Twister Lock and Cyclonic Locking System to strengthen the lock between courses. On CedarMAX this system is rated for 160 mph winds (179 mph for 8″ board and batten, ASD) and carries Florida Building Code approval FL#1712.5.
- Drop guard that keeps panels from slipping out of the lock during installation.
- Rigid EPS foam (CedarMAX only) for R-value, panel rigidity, extra impact resistance and PREVENTOL® TM3 termite protection.
What It Means on a Midwest House
Hail, high wind, freeze-thaw and humid summers punish weak siding. The ingredients above are why we are comfortable putting ProVia on houses that see all four. The rest is installation: proper nailing, room for expansion and the right trim at every joint.

Super Polymer Siding Technology Questions
What is super polymer vinyl siding?
It is ProVia’s name for its siding formulation: PVC blended with inorganic reflective pigments, anti-weathering ingredients, UV blockers and impact modifiers for better color retention and toughness.
Does vinyl siding get brittle in cold weather?
Lower-grade vinyl can. Impact modifiers keep ProVia’s panels flexible, which matters during Midwest winters when hail and cold coincide.
Is vinyl siding hail resistant?
Quality vinyl resists most hail. Foam-backed CedarMAX is rated about five times more impact resistant than non-insulated siding. Severe hail can still damage siding, and we document it for insurance claims.
What wind speed can ProVia siding handle?
ProVia rates the CedarMAX locking system for 160 mph winds and 8″ CedarMAX board and batten for 179 mph (ASD).
