Kolbe delivers comprehensive sustainability through energy-efficient Low-E coatings and argon-filled dual-pane glass that minimizes heat transfer. The company offers over 20,000 ENERGY STAR qualified products meeting California's Title 24 standards. Kolbe maintains FSC Chain-of-Custody Certification, sourcing wood from responsibly managed forests and incorporating 25-30% recycled content in glass and aluminum cladding. Their low-VOC, water-based finishes support healthier indoor air quality. These features enable homes to achieve green certifications and net-zero status.
VistaLuxe WD Line
Clean lines, more daylight.
Responsibly sourced inside and out.
Developed with architects, the VistaLuxe WD Line pairs a low-maintenance extruded-aluminum exterior with a warm, managed-forest wood interior. Its industry-leading frame-to-daylight ratio floods rooms with natural light — while recycled materials and high-performance glazing keep efficiency high.
50–75% Recycled Aluminum Durable extruded-aluminum cladding made with 50–75% recycled content. Managed-Forest Wood Warm wood interiors from renewable, responsibly managed forests; FSC-certified wood available. Double or Triple Pane Low-E, argon-filled glass that helps meet or exceed ENERGY STAR across climate zones. PDL Thermal-Break Glazing Performance divided lites let argon flow freely, so the airspace acts as a thermal break. Low-VOC Interior Finishes Water-based, low-VOC stains for healthier indoor air without sacrificing the wood look. Built to Last Fluoropolymer finishes resist corrosion and weathering for decades of low-maintenance life.
Forgent Series -
WithGlastra®
A smarter material.
Built for the net-zero home.
Forgent is built from Glastra® — Kolbe's proprietary, recyclable hybrid of fiberglass and UV-stable polymer. Its low thermal conductivity, multi-chambered frame, and welded seals deliver the kind of airtight efficiency that's helped power real net-zero-energy homes.
Glastra® Composite A recyclable fiberglass-polymer hybrid with naturally low thermal conductivity. Insulating Ladder Chambers Multi-chambered "ladder" extrusions trap air to boost insulation and strength. AccuForge™ Welded Frame A fused, welded sash and frame block air and water infiltration for a tighter, longer-lasting seal. Compression Seals Automotive-grade compression seals make for a quieter, drier, more comfortable interior. Net-Zero Proven Specified in zero-energy homes for its thermal performance and airtight construction. Energy-Efficient Glazing Low-E, argon-filled glass options engineered to match local climate demands.
Ultra Series
Traditional to modern.
Recycled, renewable, and made close to home.
