Architectural Specs

Frame Alloys & Low-E Coatings

We use virgin PVC compounds with titanium dioxide stabilizers to resist UV degradation. Multi-layer silver Low-E coatings reflect radiant indoor heat while blocking solar radiation.

  • Polyurethane foam-insulated frame cavities
  • Super Spacer® non-metal warm-edge foam
  • 20-gauge steel reinforcement on door strikes
Water Management

Sub-Sill Drainage & Flashing

Every opening receives an impermeable sloped elastomeric sill pan beneath the frame. Baffled weep holes channel wind-driven rain outside while blocking cold air intrusion.

  • Self-adhering butyl flashing taped to wall envelope
  • Low-expansion closed-cell polyurethane foam
  • Commercial-grade OSI QUAD MAX exterior sealant
Diagnostic Guide

When to Repair vs. Replace

Torn weatherstripping can be repaired simply. However, fogged glass between panes, rotting sills, or sticking frames require pocket replacement to stop heat loss.

Pocket Replacement: Preserves original interior wood casing, sills, and trim untouched while upgrading the thermal core.

Both double-hung sashes tilt inward 90° for easy cleaning from inside your home. Vinyl and composite frames require zero sanding, scraping, or repainting.

Common Questions

Dayton Windows & Doors FAQ

Straightforward answers about energy savings, timelines, and warranties.

Replacing drafty single or failed double-pane windows with Energy Star® Low-E argon units reduces annual heating and cooling bills by up to 25% to 30% (U.S. Dept. of Energy). In Dayton's winter, modern thermal barriers immediately stop cold drafts and condensation frosting on glass.

Pocket replacement inserts a custom window into your existing sound frame, preserving interior casing and paint untouched. Full-frame replacement strips to wall studs, required only if existing wood jambs have structural rot.

Insulated fiberglass doors provide up to five times the insulating R-value of solid wood without warping or rotting. Unlike thin steel doors, fiberglass resists denting, scratching, and thermal transfer while retaining a rich woodgrain finish.

Yes. Crews install one opening at a time with interior doors closed. Openings are exposed for under 15 minutes before new insulated units are set, flashed, and sealed with low-temperature commercial sealants.

You receive a 50-year non-prorated manufacturer warranty covering seals, glass breakage, and vinyl frames, combined with our local Gut R Dun Lifetime Workmanship Guarantee protecting against drafts and water leaks.
