Description
GOMIN · Glass Heat-Insulation Coating A nano glass heat insulation coating applied directly to existing architectural glass. Three grades cover the three jobs buyers ask for most — maximum heat rejection, balanced protection, and crystal-clear optical finish. All cure to a see-through film that keeps daylight and the view, while cutting the solar heat that passes through. Supplied from 1 kg MOQ. 80% heat insulation rate Indoor temp. drop 8–15°C (outdoor 35°C) · 90% UV & IR block · 50 m²/kg 3–8°C drop Balanced protection · anti-glare & anti-static · 10 m²/kg 40 μm crystal-clear Preserves substrate colour · 5 m²/kg Figures follow the product specification table. Data points not listed for a grade are available on request. Large curtain walls, skylights, atriums and retrofit projects. The biggest temperature reduction (8–15°C at outdoor 35°C) with the thinnest film (1–3 μm) and the widest coverage at 50 m²/kg. The all-rounder for facades that need more than heat control. A 3–8°C temperature drop, plus anti-glare, anti-static, stain resistance and long service life. Eco-friendly, safe and non-toxic. Architectural and decorative glass where the original colour and finish must show through. A 40 μm high-build layer that cures fully transparent, preserving the substrate tone instead of masking it. Because the coating goes on top of the glass you already have, it is a practical retrofit for buildings where replacing the glazing or applying film is too costly, too slow, or simply not permitted. GM-BL blocks the most heat with the thinnest film and the widest coverage (50 m²/kg). GM-115311 is the balanced grade with anti-glare and anti-static performance at moderate coverage (10 m²/kg). GM-115255 is the clear, high-build grade (40 μm, 5 m²/kg) for projects where optical clarity matters most. GM-BL — with an outdoor temperature of 35°C, the indoor temperature drops by 8–15°C, with a heat insulation rate of 80% and 90% UV & IR rejection. GM-BL and GM-115311 start at 1 kg. GM-115255 starts at 10 kg. Divide your total glass area by the coverage of the grade you choose — 50 m²/kg (GM-BL), 10 m²/kg (GM-115311) or 5 m²/kg (GM-115255) — then add about 10% for application loss.
