Montgomery Window Replacement provides professional energy-efficient window installation in Montgomery, AL for residential and commercial properties across the River Region. Which wall your windows are on matters more in Montgomery than which window you buy. The state energy code says so in writing, and the proof is a short table almost nobody in this trade has read.
Start with the climate. Montgomery County is zone 3A and sits in the hot-humid band, which means the cooling season dominates the year and the number that governs your purchase is SHGC, the share of the sun's heat the window admits.
U-factor matters less here than it does ninety minutes north. If a salesman leads with U-factor in this city, he is selling you a Chicago window.
Now the table. Alabama's energy code includes an exception most states do not have: in climate zones 2 and 3, permanently shaded vertical glass is allowed to satisfy the SHGC requirement instead of meeting it with glass. The shade has to be real, from an overhang, an eave or a fixed shading device, and it has to extend at least a foot past each side of the glazing.
The interesting part is how the required projection factor changes with the direction the window faces. South needs the least shade, a projection factor of two tenths.
East and west need the most, half the glazing height. North needs four tenths, with a separate allowance for a vertical fin on the west edge. Orientation is rounded to the nearest compass point.
Read that as a ranking and it tells you where your money goes. South sun is high at midday, so a modest overhang blocks it. East and west sun arrives low and horizontal, under any eave you own, which is why those two elevations need more than twice the projection and why your west-facing rooms are hot at six in the evening in July.
So the sequence we recommend is west, then east, then south, then north, and we will quote it that way if you want it that way. The west elevation is where a genuinely low-SHGC unit earns its cost. On the north side, where almost no direct sun ever lands, the same glass buys you very little and costs the same.
A note on what shade cannot do. Trees and a deep porch are the cheapest solar control available and the River Region has plenty of both, but shade does nothing for a sash that no longer closes, a failed seal, or rot at the sill. Those are repair items and they are usually the honest first invoice.
Which leads to the recommendation we give most: if your frames are sound and only the west rooms are uncomfortable, do not buy a whole-house package. Buy the west openings, or buy shade on them, and leave the rest. A house in this climate with mature canopy on three sides and eight good windows does not need its north glass replaced to be comfortable, and replacing it will not show up on a bill.

Materials, equipment and how we do energy-efficient window installation
The difference between energy-efficient window installation that lasts and energy-efficient window installation that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with asymmetric laminated insulating glass, acoustic polyvinyl butyral interlayers, outdoor-indoor transmission class under ASTM E1332, soft-coat low-emissivity coatings on surface two, 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 Montgomery 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 River Region means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Montgomery Chooses Montgomery Window Replacement
- ✓We quote outdoor-indoor transmission class, not just the sound transmission class on the brochure, because OITC is derived under ASTM E1332 from data down to 80 hertz and that is where aircraft and interstate traffic actually live.
- ✓Every elevation is walked with a compass before a product is named, so the wall facing Dannelly Field gets a different glass makeup than the wall facing the back fence.
- ✓We talk customers out of triple glazing in climate zone 3A and show them the arithmetic instead of the brochure.
- ✓Impact-rated systems are sold here on the laminated glass inside them and never on a hurricane claim that Montgomery's inland position does not support.
