Corrosion-Resistant and Thermally Insulated Architectural Envelope Solutions
FRP & PU composite door and window systems are engineered architectural framing and envelope solutions designed for environments requiring thermal insulation, corrosion-resistant performance, and long-term structural stability. Combining pultruded fiberglass (FRP) and polyurethane (PU) composite profiles with integrated thermal isolation features, these systems minimize thermal bridging, moisture-related degradation, and maintenance requirements commonly associated with conventional aluminum and steel assemblies.
HotFRP provides integrated composite door and window solutions categorized across two primary operational forms: factory-prefabricated complete assemblies engineered for immediate jobsite installation, and pultruded composite frames and profiles designed for commercial door and window fabricators, OEMs, and custom architectural applications.

Engineering Characteristics of Composite Framing Systems
Composite door and window assemblies are evaluated according to thermal efficiency, corrosion resistance, structural performance, and compatibility with architectural hardware systems.
Thermal Performance & Energy Efficiency
Fiberglass and polyurethane composite profiles provide low thermal conductivity compared with traditional metallic framing materials. This helps minimize thermal bridging, improve envelope efficiency, and reduce condensation risks in temperature-controlled or high-humidity facilities.
Corrosion & Moisture Resistance
Non-metallic composite profiles provide resistance against salt spray, chemical exposure, humidity, and moisture-related degradation, making them suitable for demanding industrial and coastal environments.
Structural Stability & Wind-Load Performance
Continuous glass fiber reinforcement combined with polymer resin systems provides structural rigidity and dimensional stability for composite framing applications requiring reliable performance under demanding wind-load and environmental conditions.
Selection Considerations for Architectural Envelope Systems
Selecting suitable composite door and window systems requires evaluating environmental exposure, structural requirements, glazing compatibility, and hardware integration rather than relying only on appearance or material type.
Environmental Exposure Conditions
Important considerations include chemical vapor exposure, coastal salt fog, continuous humidity, temperature variation, and long-term outdoor weather conditions.
Hardware & Glazing Compatibility
Composite framing systems should be selected according to compatibility with commercial hardware, hinges, locking mechanisms, and insulated glazing units (IGUs).
Referenced Architectural Performance Standards
Composite door and window systems are commonly evaluated using recognized architectural testing methods, including ASTM and AAMA procedures related to air infiltration, water penetration resistance, structural wind-load performance, and thermal transmittance (U-value) evaluation.
Typical Applications
FRP & PU composite door and window systems are applied in commercial, industrial, and specialized buildings where corrosion resistance, thermal performance, and long-term durability are critical design requirements.
