To specify the right products, architects and engineers rely on quantitative measures:

Visible Light Transmittance (VT):
The fraction of the visible solar spectrum that passes through the glazing. Higher VT values ensure brighter interiors but may invite glare without proper shading.
.

Daylight-to-Space Ratio (Window-to-Floor Area):
Many codes require window glass to cover at least 10 % of a room’s floor area to secure adequate daylight levels; a higher ratio delivers deeper daylight penetration and reduces reliance on artificial lighting
.

Operable Opening Area:
For natural ventilation, the International Building Code (IBC) mandates that the total openable area be not less than 4 % of the floor area served—ensuring sufficient airflow for comfort and air-quality control

 

Slimline Thermal-Break Profiles
By minimising frame sightlines and incorporating high-strength polyamide barriers, VIGORAWINDOWS’s systems deliver expansive glass façades without sacrificing insulation or structural rigidity.

High-Performance Glazing
Options range from ultra-clear low-iron glass for exceptional daylight clarity to spectrally selective coatings that block heat-gain while maintaining VT above 60 %.

Integrated Shading & Louvres
Discreetly incorporated external or internal shading slats temper glare and solar heat gain, letting you dial in the perfect balance of light and comfort.

Modular Ventilation Packages
A portfolio of operable configurations—including awnings, casements, pivot windows and bi-fold doors—offers tailored ventilation control. Optional insect screens, friction hinges and restrictors ensure usability and safety.

Concealed Drainage & Seals
Hidden weep-holes and multi-lip gaskets preserve clean aesthetics while preventing water ingress, so you can leave windows open for ventilation even in light rain.

 

Tropical & Humid Regions:
Maximise cross-ventilation with high-level clerestories and wide-opening casement windows, paired with overhangs to keep direct sun at bay.

Temperate Zones:
Leverage large VT glazing in north-facing façades (southern hemisphere) for passive daylighting, and configure trickle vents for year-round fresh-air supply.

Cold Climates:
Combine moderate-VT double- or triple-glazing with tight-seal operable units to harvest winter daylight while preventing drafts.

 

VIGORAWINDOWS systems are independently tested to meet global benchmarks:

NFRC (USA): U-factor, SHGC and VT labeling.

WERS (Australia): Star-rated daylight and ventilation performance.

CE (Europe): EN standards for thermal and air-tightness.

Local Codes: Custom datasheets align with national building regulations worldwide.

 

 

Health & Well-Being: Daylit spaces reduce eye strain and boost mood, while operable windows promote better indoor air quality and cognitive function.

Energy Savings: Increased daylight penetration cuts lighting loads; natural ventilation can lower cooling demands.

Design Freedom: Ultra-slim frames and versatile opening styles empower architects with clean lines and flexible layout options.

Market Appeal: High daylight and ventilation ratings enhance building credentials for green certifications (LEED, WELL) and tenant satisfaction.
