BIK Domes and Continuous Daylight by BIK enrich both home and office environments. Allowing the colours of nature to penetrate indoors, enabling you to create light, warmth and visual depth. Architecture that enhances light provides a healthy and pleasant climate in which to live and work. It contributes to an optional indoor climate. Its ongoing quest for innovation has led to products and applications of the highest quality. As befits a market leader.

BIK Domes are manufactured from high quality, durable synthetic materials. A standard dome is made of Acrylic and high impact-resistant polycarbonate 250 times stronger than glass and almost unbreakable. As well as offering high impact-resistance, polycarbonate fulfils the high requirements for fire safety. The material compiles with fire class I according to NEN 6065 / 3883, BS 476.

It has excellent thermal insulation under normal conditions; surface condensation is virtually non-existent.

All BIK Domes are supplied with instructions for their installation, use and maintenance. Durability is BIK’s guiding principle at BIK with more than 40 year’s experience,can give guarantees upto 10 years. Extra security comes with certificates for product quality (ISO 9001/2000).

The guarantee covers:
•  Normal resistance to weather.
•  Transparency.
•  Manufacture and on construct errors.

Product performance:

Polycarbonate : The polycarbonate starter sheet used for the formed glazed Sky Dome is 3 mm thick UV protected grade. Polycarbonate is intended for use where maximum strength and resistance to fragility and impact damage is required.

Fire class : We use only polycarbonate for our Sky Dome which are tested for fire propagation in accordance with BS 476:Part 7 confirmed a Class 1 rating as defined by the Building Regulations.

Dead Load : A double skin Sky Dome has been tested of the maximum perimeter of 1800 x 1800 mm with a static loading of 1250 N/m2 without any significant permanent deformation occurring.

Watertightness : In test to BS 5368:part 2 and 3 of the maximum perimeter Sky Dome achieved a rating exceeding exposure category 2000 as listed in BS 6375 achieving a watertightness of 600 Pa. (=N/m2)

Impact test : Impact test with a 50 kg soft body in accordance with PrEN ( European Standard ) have indicated that an 1800 x 1800 mm double glazed Sky Dome will resist with up to 1200 Joule which is in excess of the impact energy specified in the BS HSE SIR30 test. Impact tests with a 250 g hard body carried out with an impact energy of 2.5 J in accordance with PrEN 1873 on glazed panels showed that no damage to the weatherproofing integrity occurred.

U- Value : Calculations of the U-values of rooflights in accordance with the methods outlined in CIBSE Guide A should be carried out for Building Regulations.
