Innovation of functional windows and doors
Coating Liquid Manufacturing Technology
We have developed the high functional coating powder more specialized in the energy efficiency than the low emissivity or low-e technique coating with silver.
Existing Low-E(Low-Emissivity) glasses VS KGS technology applied glasses
Roy glass
- Metal layer (Ag, silver)
- Insulation method:coating special metal layer on glasses which has high infrared reflectance to reflect infrared rays
- Insulation performance : 1.64W/m²K
(the higher, the better)
- SHGC : 0.37 (the lower, the better)
- Low durability / a wide range of colors
KGS technology applied glass
- Material : KGS 20% + inorganic binder 20%
+ solvent (PMA) 60%
- Insulation method: evenly spreading inorganic metal oxides on the glass to reflect infrared rays
- Insulation performance : 1.72W/m²K
(the higher, the better)
- SHGC : 0.27 (the lower, the better)
- semipermanent / high heat blocking rate for its price
*Solar Heat Gain Coefficient (SHGC)
which is defined as that fraction of incident solar radiation that actually enters a building through the entire window assembly as heat gain
Comparison with other competitive products
| Division | Material | Insulation method | Performance | Remark |
|---|
| Insulation ceramic film |
Deposition of cermaic paint metal ion |
Coats material absorbing or
reflecting far-red ray |
High |
- High price
- Low durability
(surface strength 2H)
- Vulnerable to scratch
|
| Coating for DIY |
Inorganicsilicon |
Selective blocking of infrared ray by
special nano-inorganic paint |
Low |
- High price
- Low durability (Surface strength 4~6H)
- Site operation method using roller
- Occurrence of bad smell when constructing
|
| Deposition goods (Low-E) |
Metal(Ag) film |
It coats special metal film (Ag, etc.) of high reflexibility of infrared ray onto surface of glass, and reflects infrared ray |
High |
- Due to oxidation of silver(Ag), not available in single plate glass
- Durability of 15~16 years
- When using glass, durability of surface is weak, so unable to install blind of duplex type glass
|
| Functional coating glass |
New material+ inorganic binder +solvent |
Method of absorbing far-red ray within range of 780~2500nm |
High |
- Permanent durability/ Realization of various color
- High heat blocking rate, compared to price /Surface strength of 9H
- Able to use laminated glass /when using duplex type glass, Able to embed blind

Advantages of functional windows and doors
-
More than 30% of cost reduction compared with triple low-e products on the equivalent performance
-
Expected the growth of market targeting high performance and high efficiency
-
Completed the realization of performance in accordance with legal requirements related to current environmental-friendly policies
-
Possible to remodeling already installed windows and doors by placing additional glasses
- Supplying goods of high productivity and high quality
- Exclusive technology
Price Comparison compared to performance of SHGC
Features of functional windows and doors
Multiple Functional Coating Glass
-
MFCG blocks ultraviolet or UV and infrared or IR rays and puts colors on glasses
-
While conventional tin-based products block 65% and 60% of UV and IR each, MFCG based on tungsten materials blocks more than 90% of UV and IR.
Dispersion Dtability of Nanodispersed Solution
-
NS or nanodispersed solution keeps its stability for 12 months at least. (cf. other multifunctional composite materials have short expiration date due to their unsettled dispersion function)
-
One-stop solution makes it possible to minimize risks and secure cost-effectiveness and yield rates.
Binding Technology
-
Silicon-based binders are used to make coating even and to improve the adhesiveness and durability.
-
One-stop solution adopting the mixture of silicon and epoxy makes the coating process secure.
-
Typically functional windows and doors the dye-typed color coating does last more than three years, but, in contrast, functional windows and doors are semi-permanent.
