  • Priced per window on a line-item quote
  • Duracast fiberglass frames, supplied by JMB
  • Five frame colors, or dual-color
Two-story home with shake gables, new grid windows and a glass-panel entry door under a covered porch

Impervia is Pella's fiberglass line, built from its Duracast composite. Pella states the material won't warp or sag in summer heat or turn brittle in the cold, and that it expands at close to the rate of glass. Frames come in White, Tan, Brown, Morning Sky Gray or Black, or with a White interior and a darker exterior, and the finish is a factory powder coat.

On a whole house, two Impervia details shape the order. The foam-insulated frame is an option, not standard, so it is a line-by-line choice. And Pella offers triple-pane on Impervia awning, casement and picture windows only, not on the hung or sliding units. If you want triple-pane throughout, the window style of each opening decides whether you can have it, and we show that on the quote.

We order Impervia through ABC Supply, which Pella lists as a seller of the line, and we confirm the order and lead time with the branch before the quote is final. If you already bought Pella windows yourself, our labor-only Pella page covers setting them.

How do you want your quote?

Free, no obligation. Every quote is written and itemized, so you can compare it line by line.

What you supply

  • Frame color, single or dual-color, for the whole house
  • Glass for each side: Advanced Low-E, AdvancedComfort Low-E, or triple-pane where the style allows
  • Foam-insulated frames, yes or no
  • Grille pattern and hardware finish
  • Rooms cleared back from the windows on their scheduled day

What JMB supplies

  • One in-person measure of every opening, checked for rot and square
  • A quote that lists every window by room, style, size, glass and install type
  • Every Impervia window on one order through ABC Supply
  • Drop cloths and furniture covers at each opening
  • Room-by-room install with each opening closed before night
  • Sill pan, flashing tape, foam, backer rod and sealant
  • Interior jamb extensions and casing, exterior trim or capping as quoted
  • Painting new trim as its own line, or you paint it

How it is priced: per window

Quoted in writing from your photos, with a reply within one business day. What moves the number:

  • Number of windows and the share of casements, awnings and picture units
  • Foam-insulated frames and triple-pane glass where offered
  • Dual-color or Black frames versus a solid standard color
  • Replacement frame versus nailing-fin unit at each opening
  • Stucco, brick or siding around full-frame openings
  • Rot repair at sills found at the measure
  • Upper-floor openings needing staging

For the first range, send one photo of each window inside and out, labeled by room, and say whether you want triple-pane anywhere.

How long it takes

Lead time depends on the brand and is written on the quote. Installs run room by room over several working days for most houses.

Situations and options

Triple-pane where Impervia offers it

Casement, awning and picture openings can take triple-pane. Hung and sliding openings stay dual-pane, usually with AdvancedComfort Low-E for the cold.

Dark exteriors

Black, Brown and Morning Sky Gray exteriors with a White interior are offered as dual-color frames. The color is set once for the whole order.

Windows with an Impervia slider

Pella makes Impervia sliding patio doors in the same colors. Ordered with the windows, the door matches and goes in on the same schedule.

Pella Impervia Whole House Window Replacement — Fiberglass Throughout: questions, answered

Why choose Pella Impervia fiberglass for a whole house in Minnesota?

Fiberglass moves very little with temperature, so frames stay straight and seals stay tight through freeze-thaw, per Pella. Impervia also offers dark powder-coat colors and an optional foam-filled frame. It costs more than vinyl, and the per-window quote shows you how much more.

Can every Pella Impervia window be triple-pane?

No. Pella offers triple-pane on Impervia awning, casement and picture windows. Hung and sliding Impervia windows are dual-pane. We mark the glass for each opening on the quote so you know exactly where triple-pane is going.

Do you supply Pella Impervia windows or do I buy them?

We supply them on this kind of job. We order through ABC Supply and confirm availability and lead time with the branch before the quote is final. We are an independent installer, not a Pella dealer.

What has to be decided before the Impervia order is placed?

Frame color, glass by opening, foam frames, grilles, hardware finish and each opening's style and size. Made-to-order windows generally cannot be changed after ordering. Everything is written on the quote, and you sign off before we order.

How are Impervia windows installed in a stucco house?

Openings with a sound frame can take a replacement unit with the stucco left alone. Openings that need full-frame work mean cutting the stucco back, flashing the new unit and patching. The quote says which each opening gets, and the stucco patch is its own line.

Who is my contact during the Impervia install?

JMB Builders, at the number on your quote, from the measure to the final walkthrough. The same contractor writes the order and does the install, so there is no hand-off between a seller and an installer.
