Insulated Glass Units (IGUs) consist of two parallel glass panes separated by a sealed spacer, creating an insulating cavity that slows heat transfer between indoors and out
A&L Windows
. This air gap—typically 12 – 20 mm—acts as a buffer against conductive and convective heat loss, immediately doubling or tripling the R-value compared to a single pane

 

Inert Gas Filling: Replacing the air in the IGU gap with argon or krypton further curtails thermal conductivity—argon, for example, conducts heat at just 67 % the rate of air, driving down U-factors and enhancing winter-time warmth

 

Low-Emissivity (Low-E) Coatings: Ultra-thin metallic layers on the glass surfaces reflect long-wave infrared energy back toward its source, retaining indoor heat in winter or repelling solar gain in summer. Hard-coat and soft-coat Low-E options allow fine-tuning of solar heat gain coefficient (SHGC) without sacrificing visible light transmittance

Traditional aluminum spacers conduct heat at the edge of an IGU, creating a cold bridge that can lead to condensation. Vigora employs warm-edge spacer bars—made from composite or stainless-steel/polymer composites—to keep edge-of-glass temperatures higher and improve overall insulation by up to 15 %

 

Precision-Engineered Profiles: Thermally broken aluminum and reinforced composite frames maintain structural strength while slashing frame U-values.

Spectrally Selective Glazing: Choose from passive or solar-control Low-E coatings to match your climate—maximising heat retention in cold regions or minimising cooling loads in warm ones.

Custom Gas Ratios: Standard argon fills meet most needs; for ultra-slim units or extreme climates, krypton variants are available.

Integrated Shading & Control: Factory-fitted blinds or dynamic exterior screens can be incorporated into IGUs for on-demand solar management.

Smart Ventilation Configurations: Complement high-efficiency glazing with automated vents or trickle-vent frames to optimise fresh-air intake without compromising insulation.

 

 

VIGORAWINDOWS’s double-glazed systems are rigorously tested and certified to leading international standards:

NFRC & Energy Star (USA): Verified U-factor, SHGC and VT labeling.

WERS (Australia): Star-rated for energy performance.

CE (Europe): Compliance with EN standards for thermal transmittance.

Local Codes Worldwide: Bespoke datasheets align with national regulations from Saudi Arabia to South Africa.

 

Up to 30 % Energy Savings: Lower heating and cooling loads through superior insulation.

Condensation Resistance: Warm-edge design prevents moisture build-up at pane edges.

Acoustic Dampening: The same IGU cavity reduces external noise, enhancing occupant comfort.

Enhanced Daylight & Views: High-clarity glass options maintain up to 70 % visible light transmittance.

Sustainable Impact: Reduced HVAC reliance lowers carbon emissions and supports green building certifications (LEED, BREEAM).
