Raleigh Window Pros provides professional aluminum window replacement in Raleigh, NC for residential and commercial properties across Wake County. Aluminum is the right frame for some openings and the wrong frame for most houses, and the difference is a narrow strip of plastic buried in the extrusion. This page is about what that strip does and how to tell whether yours has one.
Aluminum conducts heat far better than wood, vinyl or fiberglass. An unbroken frame is therefore a continuous metal path from the heated room to the outdoor air, wrapped around the glass, and no coating on the glazing changes what the metal is doing.
A thermally broken frame is two separate extrusions. The interior half and the exterior half are joined by a non-conductive barrier rather than by metal, and that barrier carries the structural load across the gap. Nothing metallic spans from inside to outside. That is the whole difference between an aluminum window that performs and one that does not.
Two methods dominate. A polyamide strut is rolled into knurled channels in both extrusions and mechanically crimped, which is the strut-and-cavity frame. The alternative pours a resin into a channel, cures it, then machines away the aluminum bridging it, which is where the phrase poured and debridged comes from.
You can check it rather than believe it. Look for a seam running the length of the sill and the jamb, ask for the section drawing, and read the certified rating. A dark anodized or painted finish tells you nothing about whether a break exists. Any supplier who cannot produce a section drawing is quoting from a brochure.
The label governs, not the material. North Carolina is running the 2018 residential and energy codes, both built on the 2015 International Codes, with a 2024 series approved and its start date reset in a March 2025 letter. Ratings come off an NFRC 100 or NFRC 200 certified label.
On commercial frontage the product here is aluminum, and here it genuinely should be. Storefront spans, entrance doors and heavy glass need a frame that does not deflect, and our commercial page handles that work. On a house the case narrows to wide fixed lites, tall stair glass and dark finishes on long units.
The frames people call about are older than the argument. Thin sightlines, a single pane, no break and no weatherstrip left: a 1960s to 1980s aluminum window, and in Wake County it is almost always what comes out rather than what goes in. Identifying it correctly is usually the most valuable twenty minutes of the project.
When not to buy: do not pay for thermally broken aluminum on a standard residential opening where a fiberglass or multi-chamber vinyl unit reaches the same certified number for less. And do not buy anything until somebody has been up a ladder to look at the frames you already own. We would rather lose the order than sell the wrong frame for the opening.
Our insured team brings the right materials and equipment to every job — insert assemblies set into a retained existing frame, sash packs with new jamb liners and balance shoes, constant-force coil balances in a double-hung frame, soft-coat low-E on the second surface for solar rejection, stainless warm-edge spacer in a dual-seal sealed unit, poured and debridged polyurethane thermal breaks in aluminum — and backs the work with a written workmanship warranty. We serve Raleigh and nearby communities including Cary, Apex, Wake Forest, Holly Springs.

Materials, equipment and how we do aluminum window replacement
The difference between aluminum window replacement that lasts and aluminum window replacement that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with insert assemblies set into a retained existing frame, sash packs with new jamb liners and balance shoes, constant-force coil balances in a double-hung frame, soft-coat low-E on the second surface for solar rejection, spec them to the job instead of to the invoice, and write the material grades into the free estimate so you know exactly what you are buying.
Every Raleigh job runs the same way: site walk and measurements, written scope and fixed price, protection of the surrounding area, then the work itself with a daily clean-up. Years of window work in Wake County means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.
