Savannah Window Co provides professional energy efficient windows in Savannah, GA for residential and commercial properties across the lower Savannah and Ogeechee basins. Georgia amended the model energy code in both directions for this part of the state, and the result is a pair of numbers that ordinary double glazing already clears. Knowing that in advance saves Savannah owners a great deal of money.
Chatham County sits in Climate Zone 2. Georgia sets the fenestration U-factor at 0.35 instead of the 0.40 the base code would allow, then moves solar heat gain the other way, from 0.25 up to 0.27. Skylights are held at U-0.65. Take the trade-off path rather than the prescriptive table and windows are capped at SHGC 0.30 regardless.
Read those figures carefully and your shopping list more or less writes itself. An argon-filled double unit with a soft-coat low-E and a warm-edge spacer lands around U-0.30 and SHGC 0.25 without anyone trying hard. You are inside both requirements already. Anything beyond that is being sold on comfort, not on compliance, and it should be priced that way.
Which is why we rarely push triple glazing on this coast. A third lite buys U-factor nobody here had a use for, adds serious weight to a sash that still has to balance and operate, and lifts the unit price by roughly a third. In a cooling-dominated climate that money does far more work in the coating and the seal.
Solar heat gain is the number worth chasing, and orientation decides how hard. West glass takes the whole July afternoon and deserves a tighter coating with a lower gain figure. North glass under mature live oak in a shaded lane does not, and paying for it there costs you visible light for nothing. We will specify two different glass packages on one house and explain the split.
None of this touches your opening, which is precisely the point. Every improvement above arrives inside a unit built to the dimensions already in your wall. No building permit, no declared job valuation, nothing landing on a five-year cumulative total, no file crossing the floodplain manager's desk. Thermal performance is the one upgrade the flood ordinance has no view on whatsoever.
Installed performance is won or lost at the perimeter, and no sticker measures that part. A unit certified at a low air leakage rate in a laboratory does nothing useful if the gap behind the casing has been packed with loose insulation and left. We seal with backer rod and a low-modulus silicone, and use foam only in the places the manufacturer's own instructions allow.
Expect a real but moderate reduction in the bill, and be wary of anybody promising more than that. Going from single glazing to code-compliant units changes a Savannah summer noticeably, because you are removing the worst assembly in the wall. Going from sound double glazing to slightly better double glazing does not, and you will hear that from us first.
Our licensed and insured team brings the right materials and equipment to every job — pultruded fiberglass frames ordered to the measured opening, insert sash packs fitted inside an existing jamb, sill pans with end dams and a sloped back leg, flood-damage-resistant frame materials under FEMA Technical Bulletin 2, laminated impact glazing over a 0.090-inch interlayer, warm-edge spacers in argon-filled insulating glass units — and backs the work with a written workmanship warranty. We serve Savannah and nearby communities including Pooler, Garden City, Port Wentworth, Thunderbolt.

Materials, equipment and how we do energy efficient windows
The difference between energy efficient windows that lasts and energy efficient windows that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with pultruded fiberglass frames ordered to the measured opening, insert sash packs fitted inside an existing jamb, sill pans with end dams and a sloped back leg, flood-damage-resistant frame materials under FEMA Technical Bulletin 2, 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 Savannah 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 lower Savannah and Ogeechee basins means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.
