Invisible comfort. Engineered clarity.
In winter, it holds warmth close; in summer, it deflects the blaze — an invisible layer of gas quietly mediating between architecture and nature, while softening urban noise into a gentle ambient hum. Vermat Insulated Glass Units transform the building envelope into a precision-tuned barrier, combining pure transparency with exceptional thermal and acoustic performance. From towering curtain walls and expansive skylights to serene residential windows and interior partitions that define ethereal spaces, our IGUs liberate design imagination without compromise. Every pane enriches the life behind it — steam curling over morning coffee, quiet moments between pages, children chasing sunbeams across the floor.
At its core lies a hermetically sealed cavity engineered to block over 70% of heat transfer and reduce external noise by 35+ decibels — establishing the IGU as an indispensable element of modern building performance. Combined with advanced Low-E coatings, warm-edge spacers, and inert gas fillings, Vermat IGUs achieve U-values as low as 0.8 W/(㎡·K), meeting the most stringent energy codes worldwide. Fully certified to CCC, CE (EN 1279), and IGCC, and compliant with GB/T 11944, ASTM, and AS/NZS standards, each unit is fabricated on automated lines with dual-seal construction for decades of reliable service. Where clarity meets conservation, Vermat delivers glass that works as intelligently as it looks.


Key Features & Customization
Thermal Insulation Excellence
Advanced Low-E coatings, argon or krypton gas fill, and Swisspacer® or Technoform® warm-edge spacers deliver U-values ≤0.8 W/(㎡·K), minimizing heating and cooling loads in any climate.
Superior Acoustic Comfort
A precisely tuned cavity combined with optional laminated glass reduces external noise by 35+ dB, creating quiet interiors for hospitals, schools, hotels, and residences adjacent to busy streets.
Permanent Seal & Durability
Dual-seal construction (butyl primary + silicone or polysulfide secondary) with desiccant-filled spacers guarantees a permanently dry cavity and zero gas leakage, ensuring performance stability for over 20 years.
Custom Dimensions & Shapes
Fabricated to precise project specifications — maximum size 3300 × 6000 mm, minimum 180 × 300 mm, with cavity widths from 6 mm to 22 mm (9A–24A spacer). Curved, stepped, and non-rectangular geometries are fully supported.
Integrated Aesthetics & Safety
Combine with tinted, fritted, or digitally printed glass for solar control and privacy; laminated or tempered options provide impact resistance and safety to CPSC 16 CFR 1201 and GB 15763 standards.
