Sliding, multi-slide, casement and swing, and pivot — four door families across the performance tiers. Thermally broken 6063-T5 aluminum, all-tempered Low-E glazing, and custom sizes and shapes as standard.
The workhorse patio slider. Heavy-duty bottom rollers, stepped multi-track sill, factory-set weep system. Panels up to 1400 × 3048 mm (55 × 120 in).

Where an opening needs more panels than the 4075 Series carries, the TY120 takes over: up to six tracks, for indoor-outdoor walls that open almost completely. Horizon series; sizes and panel counts confirmed per project.

Horizon and Ascent figures are manufacturer whole-door values and carry no NFRC listing. Summit is NFRC certified and its certification numbers are issued with the quotation. Product-specific U-factor and SHGC vary by opening size and glazing option — see the individual data sheets.
Features other importers charge as upgrades. We ship them on every door, in every tier, because they're what makes a door a door — not because they're a differentiator.
Every lite tempered — inside and out. Zero-liability on safety-glazing on any door, any panel size.
Argon-filled, Low-E insulating glass on every door, with glass thickness set by the pane area.
Low-E on every opening, keeping solar gain low in Texas heat.
Black warm-edge spacer standard on Summit — no visible aluminum bar in the reveal.
CMECH or Roto multi-point hardware on all operables. Cast handles standard, with optional solid marine-grade 316 stainless steel.
Custom sizing and shapes to the millimeter — including opening geometry other importers can't or won't build.
Flush-recessed for interior-flow projects, high-threshold for weather exposure. Matching finish across all door families.
AkzoNobel Interpon AAMA 2604 powder coat as standard. AAMA 2605 and dual-color frames available at additional charge. Field-touch-up compatible — critical for jobsite repair.
A cross-section of installed work across Texas Hill Country custom homes and infill builds. Full portfolio in the Projects section.
