Architects

Design flexibility: Window Hub systems are modular and configurable, enabling integration with contemporary or traditional façades and complex geometries.
Performance-driven choices: Select glazing packages and frame profiles that meet thermal, acoustic, and daylighting targets for each project.
Refined detailing: Slim sightlines, coordinated hardware finishes, and consistent frame options deliver a cohesive aesthetic across elevations.

Builders

Efficient installation: Profiles and prefabricated assemblies are developed for predictable, straightforward fitting, reducing site labor and rework.
Logistics and support: Project coordination, technical documentation, and access to local supply partners streamline procurement and timelines.
Code and performance compliance: Systems are specified to satisfy airtightness, water-tightness, and energy-efficiency requirements, simplifying inspection and certification.

Window Replacement Contractors

Durable upgrade solutions: Retrofit units and replacement sashes are engineered to meet long-term performance and low-maintenance expectations.
Home efficiency improvements: High-performance glazing and thermal-frame options reduce heat transfer and help lower energy usage after installation.
Business tools: Co-marketing materials, product datasheets, and specification assistance are available to help contractors communicate benefits and grow project pipelines.

Designers

Tailored profiles: A wide palette of frame finishes and glazing options lets designers control contrast, texture, and visual weight across façades.
Custom proportions: Variable sash and mullion sizes support proportional harmony and daylight strategies while maintaining structural integrity.
Detail-first aesthetics: Concealed hardware, narrow sightlines, and coordinated accessory choices preserve the architect’s vision.

These capabilities enable designers to apply fenestration as an expressive, measurable element of building performance and occupant experience

Sustainability and Comfort

High-performance glazing: Low-E coatings, gas-filled IGUs, and warm-edge spacers support energy targets and occupant comfort.
Acoustic and solar control: Options for laminated glass, solar control coatings, and operable ventilation permit nuanced environmental control.
Material systems: uPVC and hybrid frame solutions balance lifecycle costs with finish longevity and minimal upkeep.

Specification Support

Technical guidance: Performance data, BIM objects, and joinery details are provided to integrate windows seamlessly into construction documents.
Prototyping and finish trials: Samples and mock-ups facilitate material coordination and final finish approval.
Project continuity: From concept through handover, Window Hub provides resources to preserve design intent at scale.

U-Value

0.21-0.28

A U-Value tells you how thermally efficient a product happens to be, lower numbers indicating better insulating properties

Air Leakage

0.20

Air leakage, or air infiltration, is the amount of air that passes through cracks in the window assembly, as well as the amount of air that leaks through the window frame due to window installation and sealing failures. The more air that can leak through a window, the less energy-efficient that window will be.

Heat Gain
Coefficient

0.24

The fraction of solar radiation admitted through a window, door, or skylight -- either transmitted directly and/or absorbed, and subsequently released as heat inside a home. The lower the SHGC, the less solar heat it transmits and the greater its shading ability.

Visual Transmittance

0.48

To take account of different tastes and architectural styles, modern window technology can be realized not only in white but also in GEALAN-acrylcolor® or with a décor or wood-grain foil.
