Pella Platinum Certified Contractor
Pella Impervia windows for Colorado homes. Fiberglass strength, color that lasts.
Pella Impervia windows are made from Pella’s Duracast fiberglass and finished with a powder-coat color, built for homeowners who want a strong, low-maintenance frame, slim black or colored exteriors and a clean modern look. KV Windows is a veteran-owned Pella Platinum Certified Contractor based in Westminster, and this is how we help Colorado homeowners decide whether Impervia fits their home and how to configure it.

Duracast fiberglass, made for temperature swings.
Impervia frames and sashes are made from Duracast, Pella’s own fiberglass composite. Pella describes it as a five-layer pultruded material with a patented interlocking mat, and as a thermoset, which means it won’t expand, warp or sag in summer heat or shrink and turn brittle in the cold. Pella says it has tested Duracast from -40°F to 180°F.
That matters on the Front Range, where a south- or west-facing frame can go from a frigid morning to hot afternoon sun in a single day, and where hail, wind and dry air are hard on cheaper materials. Pella also notes that Duracast won’t rot or corrode.
Impervia comes in awning, casement, double-hung, single-hung, sliding, picture and bay windows, plus matching Impervia patio doors. If you’re still choosing between Pella lines, start with our comparison of Impervia, 250 Series and Lifestyle. This page goes deeper on Impervia alone.

Powder-coat color, including black.
Impervia’s color is a powder-coat finish rather than paint. Pella says it meets the AAMA 624 standard and resists chipping, chalking and fading, so the frames never need repainting.
Five solid colors
Pella lists Black, Brown, White, Tan and Morning Sky Gray, with the same color inside and out.
Dual-color option
A White interior with a Black, Brown, Tan or Morning Sky Gray exterior. Pella notes dual-color is available on block-frame windows, not on units with an integral nailing fin, so we confirm it for your installation type.
Hardware finishes
Pella lists White, Matte Black, Brown and Tan hardware, with Satin Nickel as an upgrade.
Grilles between the glass
Grilles sealed between the panes give a divided look with flat glass that’s easy to clean. We’ll show you pattern options and how they read from the street.

Details Colorado homeowners ask about.
These Impervia features come up most often at our estimates.
Casement and awning operation
Pella lists its Easy-Slide Operator or a fold-away crank on Impervia casements and awnings, and a multi-point lock on casements operated by a single lever.
Casement windowsDouble-hung details
Tilt-in sashes for cleaning from inside, a cam-action lock, an interlocking check rail and a sloped sill to shed water, per Pella’s product pages.
Double-hung windowsGlass built for altitude
Impervia offers dual- and triple-pane insulating glass with argon, and Pella lists high-altitude glazing. We confirm the right glass for your address on every order.
Materials & glassBig combinations
Pella builds interior and exterior accessory grooves into Impervia frames for joining units, which is how we create picture-and-casement walls facing a view.
Picture windowsStrong corners
Pella lists three-way corner joints on Impervia frames, part of how a fiberglass window keeps its shape through years of heat and cold.
Matching patio doors
Impervia patio doors use the same Duracast fiberglass and colors, so a black-frame window wall and its door match.
Patio doorsWhere Impervia fits, and where it doesn’t.
Impervia tends to make the most sense when you want black or dark exterior frames on a modern, mountain-modern or farmhouse-style home, when the windows take hard sun and big temperature swings, and when you’d rather never paint a window again. You can see a black-frame Pella project we completed in Parker on our gallery page.
It isn’t automatically the right answer for every opening. If you want real wood inside to match stained trim, Pella’s wood lines may suit you better. For basements, rentals or a tighter budget, the 250 Series vinyl line is often the practical choice. Plenty of homes mix lines while keeping the exterior color and grilles consistent.
Your Impervia windows are covered by Pella’s written limited warranty, published at pella.com/warranty. KV Windows offers the manufacturer’s warranty and will show you the exact coverage for the products you choose.

Pella Impervia FAQ.
Answers to the questions we hear most from Colorado homeowners and businesses.
What is Pella Impervia made of?
Impervia is made from Duracast, Pella’s fiberglass composite. Pella describes it as a five-layer pultruded material that won’t expand, warp or sag in heat or turn brittle in the cold, and that won’t rot or corrode.
Can I get black Impervia windows?
Yes. Black is one of Impervia’s five solid powder-coat colors, and it is also offered as an exterior color on dual-color windows with a White interior. Dual-color availability depends on the frame type, so we confirm it for your project.
Will the color fade in Colorado sun?
Pella says Impervia’s powder-coat finish meets the AAMA 624 standard and resists chipping, chalking and fading, so it never needs repainting. Coverage is spelled out in Pella’s written limited warranty.
How is Impervia different from the 250 Series or Lifestyle Series?
Impervia is fiberglass with a powder-coat finish, the 250 Series is vinyl and Lifestyle is wood inside with an aluminum-clad exterior. Our comparison guide covers all three side by side.
Is Impervia a good choice at Colorado altitude?
Any Pella line needs the right glass for your elevation. Impervia offers high-altitude glazing, and we specify the right glass for your address on every order.
