1 Clear Toughened Glass

Normally the Greenhouse glass are 3mm or 4mm thickness, made to toughened glass ,the advantage is cheap and higher light transmittance,high strength to offer impact resistance.

To guarantee the best quality greenhouse glass,recommended largest sizes are:

4mm glass: 2000mm *1800mm.

3.2mm glass: 1800*1200mm.

3mm glass:1800*1200mm

2 Low Iron Toughened Glass

Low iron glass has higher light transmittance ,around 2% higher than clear glass, and as the low iron feature, glass spontaneous rate is much lower than clear glass, the glass strength is also better than clear glass.

3 Anti- Reflective Glass

Anti-reflective coating (also called “AR coating”) is a coating for glasses lenses that decreases reflective light.

The advantage of an AR coating glass :

Higher visible light transmittance, up to 95%

Lowest reflectance lower to 3%

High temperature resistance.

4 Low Iron	91	8	1.05	0.91
4 Low Iron with AR	91	8	1.05	0.91

4 Insulated Glass

With Lanjing high efficiency low-e coating glass, the VLT can be up to 80%, and keep the excellent thermal insulation.
