Building envelope systems
Specification writers lock U-factor, SHGC, and wind-load design pressures into fenestration and cladding packages before bid day—backed by NFRC ratings, AAMA certifications, and ENERGY STAR Partner pathways across new construction and renovation envelopes.
Grouped performance tables
Thermal, structural, and moisture parameters are grouped so façade consultants can map fenestration packages against cladding substrates without hunting across disconnected data sheets.
Specification advantages
Frame and sash packages document U-factor contributions so energy models stay within code budgets for IECC climate zones.
Siding, trim, and fenestration details coordinate flashing sequences that protect the weather-resistive barrier at openings.
Design pressure and coastal approvals map to structural calculations for multifamily and light-commercial shells.
Where jurisdictions require Class A exterior surfaces or rated openings, product pathways are documented for AHJ review.
Batch and plant documentation support inspector challenges when substitutions appear on the jobsite schedule.
Construction segments
Four primary markets where fenestration, cladding, and panel packages must clear wind, thermal, and moisture reviews together.
“Cornerstone’s NFRC and design-pressure packages let our façade team lock window and cladding schedules before mock-up—without rewriting energy models mid-bid.”
