Overview

About the Impervia Series

Impervia is Pella's fiberglass line, and the case for it is the material. Fiberglass holds up in demanding climates better than most window materials, which is why the line is awarded for longevity, and it carries Pella's Universal Design framing for ergonomic, accessibility-focused projects. The catalog covers casement, awning, and sliding windows plus patio doors, Florida-Product-Approval listed for residential work outside the HVHZ.

Armor Pro positions Impervia for inland and non-HVHZ Florida homes where an owner specifically wants a fiberglass frame for durability or an accessibility-minded design. It is not an HVHZ impact line, so any opening that needs a Miami-Dade NOA moves to HurricaneShield or Reserve Impact; Impervia is the choice when material longevity and Universal Design, rather than hurricane certification, are what the project is after.

Frequently Asked Questions

No. Impervia is Pella's fiberglass line, Florida Product Approval listed for residential work outside the HVHZ, but it is not an impact line and does not carry a Miami-Dade NOA. For any opening that needs impact glazing or an HVHZ permit, we move to HurricaneShield or Reserve Impact. Impervia is the choice when material longevity and durability, rather than hurricane certification, are what the project is after.

Fiberglass holds its shape and finish in demanding climates better than most window materials, with low maintenance and a low thermal-expansion rate, which is the durability case Pella makes for Impervia and why it's awarded for longevity. The tradeoff is cost: fiberglass typically runs above vinyl. In Florida it makes the most sense on inland and non-HVHZ homes where an owner specifically wants the fiberglass frame for durability or finish, since for storm protection you'd be looking at an impact line instead.

Impervia covers casement, awning, single-hung, double-hung, sliding, and picture windows plus sliding patio doors, with casement and awning models available with Pella's Easy-Slide Operator, a slide-to-vent hardware design built around accessibility and ergonomics instead of a traditional crank. The line is also offered in a commercial-grade spec for non-HVHZ commercial projects. We confirm the styles and hardware that fit your project on the quote.

We position Impervia for inland and non-HVHZ Florida homes where the driver is a long-lasting fiberglass frame or an accessibility-minded design rather than hurricane code. It can be specified into non-HVHZ commercial work too, since Pella publishes a Florida-coded commercial spec for it. Any opening that needs a Miami-Dade NOA moves off Impervia to an impact line, and we'll tell you up front which of your openings actually require that.
