Toughened glass, Class 1 BSEN 12150
Laminated glass, Class 2 BSEN 14449
Safety glass required for all door and sidelights and any glass in a window below 800mm from the floor and can be toughened or laminated glass. Laminate glass has less breaking resistance than toughened glass. Laminated glass will provide protection to internal furnishings as Ultra Violet radiation is reduced by 98/99%.
All slimlite Premier Quality Ultra Clear Self Cleaning Double Glazed Units can be constructed as the undernoted example or with any type of glass or thickness. The width of the cavities denote the insulation or U Value, and thickness of glass has little or no effect on U Values.
|Constructed 3 or 4mm Low E/3.0mm Cavity, gas/3 or 4mm clear float or Reproduction Crown||U Value 2.1||9mm, 10mm, 11mm|
|Constructed 3 or 4mm Low E/4.0mm Cavity, gas/3 or 4mm clear float or Reproduction Crown||U Value 1.9||10mm, 11mm, 12mm|
|Constructed 3 or 4mm Low E/5.0mm Cavity, gas/3 or 4mm clear float or Reproduction Crown||U Value 1.7||11mm, 12mm, 13mm|
|Constructed 3 or 4mm Low E/6.0mm Cavity, gas/3 or 4mm clear float or Reproduction Crown||U Value 1.4||12mm, 13mm, 14mm|
|Constructed 3 or 4mm Low E/8.0mm Cavity, gas/3 or 4mm clear float or Reproduction Crown||U Value 1.3||14mm, 15mm, 16mm|
|Constructed 3 or 4mm Low E/10.0mm Cavity, gas/3 or 4mm clear float or Reproduction Crown||U Value 1.2||16mm, 17mm, 18mm|
It is generally considered that warm edge spacer used in Slimlite Construction will improve current stated U Values by 0.1 - 0.2.
Triple slimlite Double Glazed Units available on application.
Double Glazed Units have a gas leakage rate and are required to have a gas leakage certificate at a rate less than 1% per annum which is BSEN1279 Part 3. The standard gas fill required is 90%, but Slimlite has an average gas fill of 96.5% and certified average leakage loss at 0.77% per annum. Therefore Slimlite has approximately 7% more gas over a period of 10 years at 89.32% and 20 years at 82.67% compared to a standard unit gas 90% fill with resulting loss at 79.33% at ten years and 74.33% at 20% years. Loss of inert gas will decrease the insulation of a double glazed unit which is important in today's escalating energy costs.
