These windows provide numerous advantages for homeowners.
Selected Pella product lines have been accepted by the National Park Service for use on projects claiming federal historic rehabilitation tax credits, which is a meaningful distinction on older Denver homes in historic districts. We will confirm which specific series qualifies for your project.
Modern designs with sleek squared-off sash profiles and expansive glass create a sophisticated aesthetic.
Exclusive hardware with sleek lines, including the Saldo fold-away crank, adds a finishing touch.
Pella windows deliver contemporary design with expansive glass, minimal profiles, and through-stile construction.
Every Pella aluminum unit carries an NFRC-certified U-factor and SHGC, plus a published Design Pressure rating. We give you the figures for your exact configuration before you order.
Aluminum conducts heat more readily than fiberglass, vinyl, or wood. In a heating-dominated climate like ours, that is worth understanding before you choose a frame material.
Thermally broken aluminum frames solve most of it. They place an insulating barrier inside the frame that interrupts the path heat would otherwise take straight through the metal, which improves the U-factor substantially over standard aluminum.
Where aluminum earns its place is structural. It carries higher loads than any other common frame material, so it holds narrow sightlines at sizes where fiberglass or vinyl need noticeably heavier profiles. On a wall of glass or a large picture unit, that difference is visible.
We will show you the NFRC-certified U-factor for the aluminum configuration alongside the fiberglass and vinyl equivalents, so you can weigh the trade-off against your openings and your budget rather than take our word for it.

Aluminum is the strongest common frame material and holds narrow sightlines at large sizes. It also conducts heat more readily than fiberglass or vinyl, so for Colorado we generally specify thermally broken frames, which include an insulating barrier within the frame. We will walk you through the NFRC ratings so you can compare directly.
Aluminum wins on structural strength and slim profiles, which matters for large openings and contemporary designs. Fiberglass generally performs better thermally and expands at close to the same rate as glass. The right answer depends on your openings, your elevation exposure and your priorities.
Very little. Factory-applied finishes on aluminum resist chalking and fading, and the frames will not rot, warp or need repainting. Routine cleaning of the frame and tracks is generally all that is required.
