Schenectady Windows provides professional aluminum window replacement in Schenectady, NY for residential and commercial properties across the Mohawk Valley and Capital Region. We will not sell residential aluminum frames at 6,357 heating degree days. That is a position, and as of this year the code puts a number behind it: a replacement window in this city has to read a maximum U-factor of 0.27.
Where that figure comes from is new and worth getting right. New York replaced its whole code suite on 31 December 2025, with no transition period. Replacement fenestration is governed by section R503.1.1.1, which sends you to Table R402.1.3, and that table sets 0.27 on U-factor and 0.40 on solar heat gain. The same pair applies in Zone 4 and Zone 5 alike.
Note how tight 0.27 is. It is materially stricter than the repealed code allowed, which turns discounted old stock into a compliance trap rather than a bargain. Anything written against the 2020 Energy Conservation Construction Code is describing a document that no longer exists.
Now the mechanism this page exists for. The code names no frame material anywhere. A thermally broken aluminum unit with a decent glass package can reach 0.27, and we fit that material on commercial work without reservation. A bare aluminum frame cannot get near it, and no coating or gas fill will carry it there.
The break is two extrusions, one facing the weather and one facing the room, joined by something that is not metal. Where that joint is missing, the frame is a single conductor and the inside face of it runs near the outdoor air, which is what puts frost on the sill horn in a room where the glass itself looks fine.
What you likely have, given the stock. Roughly four in five housing units here were built in 1969 or earlier, so aluminum shows up as triple-track storms hung over original wood sash, as 1960s and 1970s prime sliders, and as coil stock wrapped over old exterior casing to make a re-clad house look finished. That last one is a cosmetic upsell, not a window.
Aluminum is the correct material a few blocks away, and we specify it there without the reservations we hold about putting it on a house. Thermally broken storefront framing is what belongs on Lower State Street and Erie Boulevard, where a frontage that looks like one 1970s system often has three eras of construction behind the sill.
The permit is a contractor's job here. Windows are absent from the ordinary-repairs certificate the Bureau of Code Enforcement issues at 105 Jay Street, so this is permitted work, filed by us rather than by you, with the insurance certificates attached. There is no state license for this trade in New York, so ask who issued any card you are shown.
So the recommendation. Residential aluminum stays out of the house. Do not buy old-stock units priced against the repealed table, because a unit that cannot be permitted is not cheap at any discount. Where an aluminum storefront frame is sound, reglaze it and upgrade the spacer. Where a bare residential frame is finished, replace the unit rather than paying to put good glass inside a thermal bridge.
Our insured team brings the right materials and equipment to every job — asbestos-cement shingle left intact behind an insert flange, interior stop removal in place of an exterior casing cut, low-expansion foam and backer rod at the shim line, warm-edge spacer in an argon-filled sealed unit, soft-coat low-emissivity coating on the third glass surface, fusion-welded extruded vinyl frames — and backs the work with a written workmanship warranty. We serve Schenectady and nearby communities including Rotterdam, Niskayuna, Glenville, Scotia.

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 asbestos-cement shingle left intact behind an insert flange, interior stop removal in place of an exterior casing cut, low-expansion foam and backer rod at the shim line, warm-edge spacer in an argon-filled sealed unit, 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 Schenectady 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 the Mohawk Valley and Capital Region means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Schenectady Chooses Schenectady Windows
- ✓We establish the original construction date and the cladding type before we quote, because construction begun after January 1, 1974 sits outside New York's asbestos survey rule and roughly four in five housing units in this city do not
- ✓Insert installs are our default rather than our compromise, since keeping the exterior layer intact is what keeps a Schenectady window job ordinary, and we write the daylight loss on the quote instead of hiding it
- ✓Two-family and three-family houses are priced flat by flat, and we tell owners when doing only the upper unit this year is the better use of the money
- ✓We will not sell residential aluminum frames at 6,357 heating degree days, and we will not sell impact glazing in a county that sits nowhere near a wind-borne debris region
