GOMIN · Glass Heat-Insulation Coating
Three grades, one transparent family
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.
GM-BL
80% heat insulation rate
Indoor temp. drop 8–15°C (outdoor 35°C) · 90% UV & IR block · 50 m²/kg
GM-115311
3–8°C drop
Balanced protection · anti-glare & anti-static · 10 m²/kg
GM-115255
40 μm crystal-clear
Preserves substrate colour · 5 m²/kg
How the three grades differ

Pick the grade that fits your project
Choose GM-BL for heat
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.
- Heat insulation rate 80%
- UV & IR rejection 90%
- Visible light transmittance ≥70%
- MOQ 1 kg
Choose GM-115311 for balance
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.
- Indoor temperature drop 3–8°C
- Anti-glare, anti-static, anti-radiation
- Excellent ageing & stain resistance
- 10 μm dry film · 10 m²/kg · MOQ 1 kg
Choose GM-115255 for clarity
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.
- Crystal-clear after cure
- 40 μm build · 5 m²/kg
- Fully preserves substrate colour
- MOQ 10 kg
Performance snapshot
Where these coatings are used
- Curtain walls and façade glass on office towers, hotels and apartments
- Skylights, atriums and glass roofs
- Shopping malls and shopfronts
- Sunrooms and residential retrofits
- Industrial and agricultural glazing
- Public transport glazing where window film is not allowed
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.
Common questions
In one line, what is the difference between the three grades?
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.
Which grade gives the largest temperature reduction?
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.
What is the minimum order quantity?
GM-BL and GM-115311 start at 1 kg. GM-115255 starts at 10 kg.
How much coating does my project need?
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. Send us your area and we will confirm the quantity.
Can I order a sample before a full order?
Yes. Trial quantities are available so you can test adhesion, clarity and heat performance on your own glass. Tell us your glass area, location and target performance and we will recommend the grade.
Not sure which grade fits your project?
Send us your glass area, location and the performance you need. We will recommend a grade, calculate the quantity and quote from 1 kg.
