Our factory manufactures Polyurethane Doors & Windows reinforced with FRP / GRP fiberglass for strength, insulation and durability. We supply custom systems for residential, commercial and industrial projects with energy efficiency, weather resistance and long service life.
High-Performance Fiberglass-Reinforced Polyurethane Doors & Windows for Thermal Efficiency
Polyurethane Doors & Windows deliver high-strength, non-metallic thermal-break frames engineered for low-energy buildings, coastal projects and demanding commercial applications. These systems combine glass-fiber reinforcement with a polyurethane matrix to produce lightweight profiles with exceptional thermal insulation, structural strength and long-term weather resistance. Specifiers, OEM buyers and procurement managers choose these systems for energy targets, corrosion resistance and predictable production tolerances.
fiberglass reinforced polyurethane doors and windows
Reinforcing polyurethane with glass fiber yields profiles with a very low thermal conductivity, making the frames effective thermal breaks in multi-pane assemblies. The composite approach keeps frames non-conductive while delivering mechanical performance similar to some metals, but at lower weight.
polyurethane thermal-break doors and windows for passive house
Designed to integrate with double- or triple-glazing packages, these systems meet stringent low-energy window targets and are engineered to achieve industry-leading U-values in practice. Their multi-chamber seals and factory-controlled assembly deliver repeatable thermal results for passive-house and ultra-low-energy projects.
FRP polyurethane fire-rated windows 1-hour
Where passive fire performance is required, specific PU composite assemblies are configured to meet time-rated whole-window fire performance while maintaining thermal separation and airtightness for building-envelope integrity.

Quality Assurance & Compliance
Material batches are tested for thermal conductivity, mechanical strength and chemical stability. Independent lab results support U-value, air/water tightness and acoustic ratings for representative assemblies. Low-VOC polyurethane systems and inert glass-fiber reinforcement reduce on-site emissions and simplify installation safety.
