Section A

Scope of Work

Everything written into the contract before the first nail. Lines are itemized, not bundled.

  • / 02Low-E coatings and argon-filled panes
  • / 03Hurricane-impact glass available
  • / 04ENERGY STAR–rated for Gulf Coast climate

Section B

Build Tracks

Three lanes most energy-efficient windows jobs fall into. Pick a lane on the walk-through; the budget follows.

01Track A

Vinyl replacement

Best value. Welded frames, foam-filled chambers, no maintenance for decades.

02Track B

Fiberglass

Stronger and thinner frames than vinyl — more glass, more view, paintable.

03Track C

Aluminum-clad wood

Real wood interior, aluminum exterior. Premium look for historic and high-design homes.

04Track D

Impact / hurricane-rated

Laminated PVB glass that meets coastal wind-borne debris code — also slashes outside noise.

Section C

Materials & Method

Window performance comes down to four numbers: U-factor (insulation), SHGC (solar heat blocking), VT (visible light), and air leakage. For Houston, we spec SHGC ≤ 0.25 and U-factor ≤ 0.30 — a meaningfully tighter envelope than builder-grade units. Argon-filled double-pane glass with a soft-coat low-E layer typically pays back the upgrade through electric bills in 4–7 years.
