What is it?
Thermal Glass Coat is a revolutionary product which has been developed using nano technology. It’s a double glazing and window film alternative to glass insulation. It’s a liquid, that turns your ordinary windows into high performing insulation glass.
How do you apply it?
Simply, we basically paint it onto your windows. A roller is used to spread the liquid across the glass. When it cures, your window is clear.
How does it work?
In the winter, the heat you generate inside your home, is absorbed into the glass, forming a heat curtain, or barrier. Neither Double Glazing or window film can does this, which is why the coating is so effective. Normally, if you stand near your windows when the room is cold, you will feel the cold air near the glass. With Thermal Glass Coat, because the glass warms up, as the room warms up, this does not happen.
In the summer, the process is reversed. The thermal barrier is formed on the outside, so the heat from the sun, cannot bake your home or business.
How much solar energy does Thermal Glass Coat reject?
Based on Thermal Glass Coat coated onto 6mm clear float glass, it can reject a total solar radiation of about 50 %, these includes 90 % of IR, 99 % of UV and 15 % of visible light.
What is so special about Thermal Glass Coat Coating Since There Is Not Much Difference In the Physical Appearance After It Is Applied Onto The Glass?
Solar radiation rejection on 6mm clear float glass is 20%. After application it is 46%, including 99% harmful UV and 90% IR. Hence, Thermal Glass Coat will help to create a more conducive living environment while you can enjoy clear view and maximise natural light harvesting for the reduction of artificial lighting.
How can the heat be blocked since the VLT of Thermal Glass Coat is very high?
(How does Thermal Glass Coated glass offer heat reduction?)
Unlike most tinted glass, which blocks most of the visible light and allows transmission of the IR, Thermal Glass Coat blocks the solar IR to 90% while allowing high visible light transmission of 72%. That means Thermal Glass Coat coated glass allows more light transmission rather than heat.
Will the Thermal Glass Coat coating cut/block the incoming sunlight and make the interior look darker?
No, the visible light transmission drops by only 10~14%. For example, based on 6mm clear float glass, before coating VLT is 88% and after coating is 72% but it can still cut off up to 90% IR and 99%.UV.
Does tinted glass provide the similar effect like Thermal Glass Coat, reducing the heat?
Tinted glass can reduce the heat. However, the trade off is loosing VLT (light). But Thermal Glass Coat coating provides high VLT which lets the natural light coming in more while providing UV cut up to 99% and IR cut up to 90%.
How much energy can be saved before and after coating?
Energy saving simulation is very complicated and requires a special engineer to simulate it if it required on an individual basis.
On average, Thermal Glass Coat reduces temperature around 5 – 12 deg C, on extreme cases, 7-10degC.
Does the Thermal Glass Coat increase the Energy Absorption or the Energy Reflection?
Thermal Glass Coat coating is absorptive.
How can the 10% of Infrared Transmittance give 55% of DET (Solar trans)?
Total solar spectrum covers from 280nm to 2,500nm which consists of UV, Visible light and Infrared. Each of them typically occupies 2%, 47% and 51% of total solar energy respectively. Therefore, while Thermal Glass Coat coating only transmits 10% of Infrared, there are still about 50% of solar energy which comes from UV and Visible light, to be addressed. Hence DET 55% is the result.
Does Thermal Glass Coat coating take out glare?
Thermal Glass Coat provides a slight reduction in VLT, resulting in less glare without compromising the clear view.
However, it does not remove the glare completely, since the main target of the Thermal Glass Coat is to harvest the VLT to the maximum level.
Will Thermal Glass Coat distort the image like film?
Thermal Glass Coat creates minimal distortion.
Thermal Glass Coat coating is chemically bonded onto the glass without adhesive; therefore it is bubble-free.
Moreover, once it is cured, it forms the structure similar to that of the glass. Hence the image distortion remains minimal.
Physical properties/warranty of Thermal Glass Coat
What is the durability of Thermal Glass Coat? Does it bubble or peel like tinted films?
Thermal Glass Coat has the similar composition as the glass. Thermal Glass Coat is chemically bonded to the glass without using adhesive. It won’t bubble and peel off from the glass surface like film. Thermal Glass Coat provide 10 years warranty against cracking, bubbling and peeling.
What is the thickness of Thermal Glass Coat coating? Film thickness?
The thickness of Thermal Glass Coat is an average of 7 micrometer while most films are about 40 micrometer thick. (Depending on the film).
When the glass breaks, can Thermal Glass Coat hold the glass like the film does? Does film provide better safety feature?
Thermal Glass Coat doesn’t change any glass safety specification, which means if the original glass is supposed to break at certain impact, it does break.
Is Thermal Glass Coat coating scratch resistant? What is the hardness of the coating?
The Hardness of Thermal Glass Coat coating is 5H. However, it is not scratch-proof, standard glass
has a pencil hardness of 7H
Is Thermal Glass Coat coating fire resistant?
Thermal Glass Coat coating is combustion resistance, tested under JIS R3211:1998 and JIS R3212:1998.
How long can Thermal Glass Coat coating last?
Thermal Glass Coat has a 10 year warranty against bubbling, peeling and cracking.
Laboratory test show a much longer durability but it has not been around that long to be able to be definite.
What is the maximum or minimum size of the area that Thermal Glass Coat can coat?
No limit on height. Width can be as wide as 4m.
Are there any noticeable joints after Thermal Glass Coat coating?
Unlike film, which comes with fixed size, Thermal Glass Coat coating is seamless. You won’t see any joints on the coated glass.
Is there any glass that cannot be coated?
Thermal Glass Coat cannot be applied on coated glass surface such as reflective glass (coated side), low e glass (coated side), frosted glass (treated side), decorative (printed side) and wire glass.
Thermal Glass Coat is interior coating or exterior coating?
Thermal Glass Coat is mainly used in interior coating but can also be used for exterior coating in some circumstances
What colour can Thermal Glass Coat provide?
Currently, Thermal Glass Coat has a slight bluey, green tint, it is clear view with low haze level.
How long does it take to be coated?
Depending on the windows sizes, a 2 person team can apply 20- 25 sqm per day
Can Thermal Glass Coat be coated on tinted film?
No. We have to remove the film first before appling the liquid on the glass.
What is the smell after coating onto the glass and why has this type of smell? Does the smell after coating affect health?
It contains solvents and it will dissipate in 1 day. Once the product is touch dry, windows can be opened to allow ventilation and the smell will disappear quite quickly. If you are sensitive to the smell, it is advisable not to stay in the area being coated for the day. It really is best to not have anyone at home while to application is being carried out, and pets need to be outside away from the application.
Thermal Glass Coat is a liquid coating and will probably attract air born dust. How are you going to make sure the level of this is minimised?
We ask that you vacuum and dust the room, turn off all ventilation systems prior to our arrival and ensure pets are outside. As part of our cleaning process we wipe down the window frames with a damp cloth, this helps settle the dust, we also use drop sheets to work on, and make sure all doors are kept closed.
Do you need to dismantle the glass panel during the coating?
No. Coating application will be done on site, without removing the glass from the frames.
How do you ensure the coating thickness of Thermal Glass Coat?
By controlling the amount of the liquid on the specific area at the specific ratio.
All authorised applicators are trained to follow the application instructions, which are designed to make sure uniform finish of the coating.
It also has a self-levelling property to spread uniformly if proper application process is observed.
What are the precautions to clean the Thermal Glass Coated glass? What detergent shall we use?
You can wash the window by using soft cloth and mild detergent, but just water and a microfibre cloth does the job very well. Do Not use any acidic or alkaline detergents.
