Protect your home furnishings from sun damage and keep your rooms cooler this summer.
Double Glazing is easy to compare to, but Window Film is tricky because there is a massive variance in quality, performance and cost. You can get high quality Window film with comparable performance to our Thermal Glass Coat, but it does cost a lot more.
In Clarke’s beach, a couple were quoted $9,000 for 2 very large, high windows in their lounge to be Double Glazed. We did their whole house for $6,000. High performance Window Film would have cost around $11,000. The job took 2 days. After the 1st day, in the lounge we’d only done the 2 large, high windows. The next morning, the client said “that stuff is amazing, I turned the heat pump down 3 degrees last night, and you haven’t even coated the other windows in the lounge yet”.
In Mt Wellington, a Father of a local Church got 3 Double Glazing quotes for the Church’s home. The lowest was $19,000. We did it for $4,000. High performance Window Film would have cost around $7,000. He reported … “I do not use any heating during the day as it is no longer necessary.”
Solar Radiation Reflectance
The percentage of solar radiation that directly reflected by a glass to the outside of a building.
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.
Fading & Sun Damage
1) Darkens the appearance of windows
2) Because an adhesive is used to fix the film to the glass, and adhesive is affected by heat, over time it often bubbles, wrinkles and lifts.
3) Because the film comes in set widths, joins are necessary and can be seen on larger windows
4) Will often need replacing after 7 – 15 years
5) Reduces the level of natural light which passes through the glass
6) Changes the colour intensity of your view
7) Alters the colour hues of home furnishings and interior design. uv-film
8) Film is flammable
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.
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.
