Window Tint Film Alternative | UV Protection | Insulation

At last! An alternative for window insulation and UV protection that costs much less.

How its works

THERMAL Glass Coat is a liquid coating which is applied to your existing glass. This coating is very new technology that transforms your windows into thermal insulation barriers, blocking Infrared Radiation keeping heat inside in winter and outside in summer.



The image above, shows the same window a few hours later, once Thermal Glass Coat has cured to touch dry. As you can see, other than the slight tint, you would not even know it is there.


This image above shows Thermal Glass Coat being applied. It is a liquid “painted” onto your windows curing to ‘touch dry’ in a couple of hours and fully cures in about 7 days.

How We Feel Warm In Our Homes

The warmth felt from the sun is not warm air, it is actually Infrared Radiation (IR) and is commonly referred to as being in 2 forms – near infrared, nearest the sun, and far infrared furthermost from the sun. The IR we feel most as warmth on our skin is in the 700 – 1000nm range.

The sun’s rays are transformed into Radiant Heat when they strike a surface and are absorbed by that surface giving off heat.

We also generate Radiant heat with our heaters, when cooking etc. our bodies give off radiant heat, in fact all surfaces that are above 0°c give off Radiant heat.

 

How Thermal Glass Coat works

Thermal Glass Coating is an advanced liquid coating using nanotechnology that insulates windows, keeping a home or office warm in winter and cool in summer, and is a cost effective alternative to retro-fit double glazing.

Utilizing both Sol-Gel & Nano Technologies, it offers some benefits that Double Glazing and Window Film can not offer.

Thermal Glass Coat is a clear liquid coating that chemically bonds to the inside surface of the glass without the use of adhesives. No matter how severe the weather is Thermal Glass Coat will not peel, blister or bubble and is non-toxic after it is applied. Unlike window film, Thermal Glass Coat is a liquid. It ‘self levels’ at room temperature, this means the coating will be seamless and therefore is really no limit to the size of the area it can be applied to, and the application is carried out on site.

– Provides 99% UV Protection
– Cutting Ultraviolet and Infrared Rays – Dramatically Slows Sun Damage

A protective coating developed in Japan, Thermal Glass Coat cuts out 99% of the UV rays and reduces heat loss by blocking off up to 90% of infrared rays. And the beauty of it is, it does this with little hindrance to the passage of visible light coming through your windows, so you can still enjoy the benefits of natural light.

 

About Radiant Heat

Because THERMAL Glass Coat blocks Infrared rays the radiant heat which is generated in the room stays in the room, this achieves a more constant mean radiant temperature this gives you a more comfortable warmth.

It is been proven that with radiant heat, you feel warmer and more comfortable at a lower temperature, which means you use less energy to keep warm.

Understanding Solar Energy, Infrared Radiation and Glass

Solar Spectrum

The Solar Spectrum is part of the Electromagnetic Spectrum. It is commonly divided into three bands:

Ultra-violet (UV) 280nm – 380nm
Visible light 380nm – 780nm
Infra-red 780nm – 2,500nm

*Above definitions are based on ISO9050. Other standards may have slight variations on the definitions.

The energy distribution within the solar spectrum is approximately

2% UV
47% Visible light
51% Infra-red

It is important to understand that the shorter the wavelength (i.e. the lower the nanometres), the higher is the energy associated with the radiation. This is highlighted by the fact that it is the shorter wavelength, high energy UV light which causes humans to sunburn, fabrics to fade and plastics to deteriorate. While the longer wavelength, low energy radiation produced by the visible light and infra red bands are less damaging.

Visible (Natural) Light

The wavelength of the light in the visible spectrum transmitted through the glass. The spectrum for visible light is from 380 nm to 780 nm.

Visible Light Reflectance

The percentage of light in the visible spectrum that reflected by a glass to the outside of a building.

RAT Equation

When the combined UV, visible light and infrared (solar energy) strikes glass it is reflected (R), absorbed (A) and transmitted (T) in different proportions, depending on the type of glass involved. This gives us the RAT Equation which accounts for 100% of solar energy. For example, 3mm clear float glass Reflects 8% of solar energy, Absorbs 9% and Transmits (directly) 83%.

UV Light Transmittance

The percentage of UV light in the UV spectrum transmitted through a glass. The spectrum of UV light is from 280 nm to 380 nm.

Solar Radiation Transmittance

The percentage of solar energy in the solar spectrum directly transmitted through the glass. The spectrum of solar radiation is from 280 nm to 2500 nm.

Solar Heat Gain Coefficient

Solar Heat Gain Coefficient (SHGC) measures how well a product blocks heat caused by sunlight. The lower the solar heat gain coefficient, the more solar energy block. The SHGC is the fraction of incident solar radiation admitted through a window, directly transmitted and absorbed, then subsequently released inward. SHGC is expressed as a number between 0 and 1.

Shading Coefficient

The shading coefficient is the ratio of solar heat gain admitted through the glass as compared to the solar heat gain admitted through 1/8? (3mm) clear glass.
1/8? clear glass = 0.87 SHGC
1/8? clear glass = 1.0 SC
Both the SC and the SHGC are values which represent the solar heat gain through the glazing from the total solar energy spectrum. They do not necessarily have a direct correlation to visible light transmittance.

U-value

The U-value is a measure of how well heat flows through an object (thermal conductivity), is the rate of heat gain or loss through a glazing unit due to environmental differences between outdoor and indoor air It is also referred to as the heat transfer coefficient or the coefficient of heat transmission.
The lower the U-value, the better the insulation value of the material.
It should be noted here that it is ALWAYS the heat that transmits through an object not cold.

Sol-Gel & Nano Technologies

Thermal Glass Coat is an advanced coating that utilises Sol-Gel and Nano technologies. It comes in liquid form, and within a few hours of application, Thermal Glass Coat forms a very durable seven micron thin solid layer which has chemically bonded on to the glass surface. Through the combination of the technologies, the Thermal Glass Coat coating is able to self-level on its own at room temperature.
With agents like ultraviolet and infrared absorbers and colour pigments, Thermal Glass Coat is today’s solution to solar control.

Crystal structure for unchanged clarity

Thermal Glass Coat retains the original specifications of your glass windows, keeping it clear as you intended it to be.
With Thermal Glass Coat, you get a long-lasting coating that blocks out the suns UV & IR rays, but not the light, giving you optimum clarity, day and night. You appreciate the view – now you can appreciate the window too.

Durable and safe Glass-like hardness

Thermal Glass Coat chemically bonds onto glass to form a durable, glass-like layer. No matter how severe the weather is, Thermal Glass Coat won’t peel or crack. Unlike conventional solar control products, with proper care, Thermal Glass Coat can stay on your glass for a very long time.

Extended warranty

Thermal Glass Coat comes with a 10 year warranty against peeling, cracking and bubbling. You get lasting protection without the worries of re-installations or tedious maintenance.

Non-toxic material

Thermal Glass Coat is non-toxic once it has cured.

Maintenance of Thermal Glass Coat

No special maintenance is required. Simply wash windows with soft cloth a mild detergent. Ensure that no acidic or alkaline detergents are used.
