Production builders and custom home contractors trust Cornerstone for consistent supply of windows and doors that meet energy code requirements in every climate zone.

Project Case — Southeast Residential Development (2023)

Longleaf Homes Group (Georgia, Tennessee, Carolinas) specified Cornerstone double-hung windows — U-Factor 0.27, SHGC 0.21 — across 340 single-family starts in 2023. All units met IECC 2021 energy code requirements for Climate Zones 3–4. Plan review approval rate: 100% on first submission. Zero documentation-related delays across the full program year.

Multifamily & Mid-Rise

Multifamily developers require building envelope products that combine design versatility with cost predictability across hundreds of identical units. Our direct-to-builder distribution model and on-site technical representative support simplify specification and procurement for garden-style, podium, and wrap-type multifamily projects.

Project Case — South Florida Podium Project (2022–2023)

Coastal Build Partners LLC (Broward County, FL) specified Cornerstone Miami-Dade NOA-listed sliding windows and impact patio doors across a 120-unit podium project completed in Q4 2023. Florida Product Approval numbers were provided for all openings at bid stage. Code submission to permit issuance: 11 business days — approximately 3 weeks faster than prior projects where the developer sourced documentation from multiple suppliers.

Renovation & Replacement

Replacement contractors and remodeling companies benefit from our broad size matrix, which covers the most common rough opening dimensions for existing homes. Our insert and full-frame replacement windows are available in quick-ship programs to minimize homeowner disruption, and our warranty coverage transfers to new owners — a meaningful selling point for contractors closing renovation sales.

Project Case — Twin Cities Renovation Program (2022–2024)

Halverson Exterior Solutions (Minneapolis–St. Paul metro) transitioned their full siding replacement program to Cornerstone vinyl in early 2022 after two consecutive color-match failures with a prior supplier. Over 18 months and 47 completed re-sides through mid-2023, the company recorded zero homeowner callbacks related to siding color or fade performance. Average installed cost: $4.80/sq ft for horizontal lap profile. The transferable limited lifetime color warranty became a documented closing advantage on 12 of those 47 jobs.
