Technical Data
Polarlight Acrylic Block Panels/Windows are manufactured from high grade Acrylic Pellets to a unique formula in compliance with European and American Standards including:
- Impact Resistance
- Energy Efficiency
- Severe Weather
- Air Infiltration
- Water Penetration
- Uniform Load/Structural
- Sound Insulation Values 26dB
Impact Resistance
- Tested by the British Standards Institute under the conditions of BS6206 Safety Glass Class B (remained intact)
- Tested to US safety glazing standard – ANSI Z97.1
Fire Standards
- Tested to British Standard BS476 Part 7 (Surface Spread of Flame) Class 3
- Tested to US standard - ASTM D635-91 (rate of burning)
- Tested to US standard – ASTMD1929-91 (ignition temperature)
Energy Efficiency
- U value – 3.12 W/M2K (35% more efficient than glass block)
- Low E option also available with a U value of 2.27 W/M2K
- When 'drop glazed' into uPVC with windows these values will lower depending on the efficiency of the uPVC frame.
Accelerated Weathering
- Tested to US standard - G155-00a (5,000 hours)
Air Infiltration
- Exceeds US standard - ASTM E283 (1.57 PSF) (zero infiltration)
Water Penetration
- Tested to US standards – ASTM E547 & E331 (10.5 PSF) (no leakage)
Uniform Load Structural
- Tested to US standard – ASTM E330 (+-67.5 PSF) (no damage)
Forced Entry Resistance
- Tested to US standards – ASTM F588 & F842
Light Transmission
- Tested to US standard – ASTM D-1003
Patent Breathing Method
- This technology alleviates any stress buildup from normal expansion and contraction due to daily environmental and weather changes.
Sound
- Indicative test 26dB
UV Protected
Ultra violet inhibitors are built into the high quality acrylic used in manufacturing PolarLight acrylic block panel/windows, protecting them from yellowing and ageing over time.
