Material Performance

A Frame Material That Supports Performance and Design

Pultruded fiberglass provides a combination of structural strength, dimensional stability and low thermal conductivity that makes it well suited to demanding building-envelope applications.

Thermal Performance

Fiberglass has low thermal conductivity compared with highly conductive frame materials, helping reduce heat transfer through the frame and support better overall fenestration performance.

Dimensional Stability

Fiberglass expands and contracts at a rate closer to glass than many conventional frame materials, helping maintain alignment and long-term unit stability through temperature changes.

Structural Capability

The strength of pultruded fiberglass can support larger glazed areas, custom configurations and clean architectural profiles, subject to product-specific engineering and project requirements.

Narrow Sightlines

Strong frame profiles can help reduce visual obstruction and increase the proportion of glass within the opening while maintaining required performance.

Durability

Fiberglass resists rot, corrosion, swelling and moisture-related deterioration, supporting long service life and reduced maintenance requirements.

Final sizes, configurations and performance values must be confirmed against the selected SILEX system and project-specific requirements.

Yes, CAD, DWG and PDF details are fully accessible for our architectural partners. These include standard installation details, perimeter conditions, and structural interface configurations.

Available information may include comprehensive U-value charts, Solar Heat Gain Coefficient (SHGC) profiles, air tightness values, and localized thermal modeling reports to satisfy strict energy modeling metrics.

The SILEX PH95 Series is a Passive House certified high-performance window line, designed to minimize thermal bridging and optimize absolute envelope efficiency.

Yes. SILEX has published third-party verified Environmental Product Declarations (EPDs), which deliver comprehensive transparency regarding the life-cycle environmental impact of our premium systems.

SILEX fiberglass systems are engineered with incredible dimensional stability, allowing for expansive custom architectural configurations, heavy glazing profiles, and maximized natural daylight openings.

Available test reports outline extensive NAFS and ASTM compliance, including specific performance classes, water penetration resistance, and structural design pressure maximums.

Yes. SILEX products are purposefully rated and structurally calculated to satisfy the rigorous physical demands of mid-to-high rise commercial, institutional, and multi-family modern developments.

Early involvement during the initial design development phase allows our technical consultants to optimize window spans, coordinate accurate framing details, and verify overall thermal compliance early in the process.

No individual product can automatically satisfy whole building codes. However, SILEX systems provide the physical testing metrics and thermal certifications required to achieve aggregate compliance and target LEED or Net-Zero standards.
