Secure by Design - Building regulations Part Q compliant solution available. Please Call: 0116 2610 710

Description

Our Secured By Design pyramid rooflight has been tested by a leading independent testing facility, BRE (Building Research Establishment) and achieved LPS 2081:Issue 1 certification. This means that our rooflights conform to the requirements set out in The Building Regulations Approved Document Part Q (Secured by Design). The test involves a timed manual attack using various methods to determine whether the rooflight can withstand an attack by an intruder.

To achieve Secured By Design Part Q certification, our rooflights are double-glazed with an outer pane of clear toughened and HEATSOAKED safety glass and an inner pane of clear laminated glass. If required we offer blue, bronze or grey tinting or if preferred, an obscure finish for privacy or high-performance solar control to minimise solar gain (heat) (g) and maximise light transmittance (Lt). Unlike traditional ‘stepped edge’ glass rooflights where the outer edge of the glass is vulnerable to breakage, our rooflights fully enclose the double-glazed units within the perimeter framework to eliminate this risk. The top surface of the double-glazed unit is flush with the external face of the perimeter frame to allow rainwater to disperse rapidly, minimising cleaning and maintenance requirements.

Our frameless low pitch secured by design pyramid rooflight uses the same technology as our lantern rooflight which means it has no internal hip framework ensuring that the maximum amount of natural light can penetrate the room beneath. Not only does this give a more contemporary appearance, but structural silicone glazing techniques offer greatly improved thermal efficiency when compared to similar products that rely on supporting internal aluminium framework.

This rooflight is also available without external cappings for a truly frameless external appearance.

Our rooflights achieve outstanding thermal performance. True U-value and Ud-value available upon request.

The extruded thermally broken aluminium perimeter frame is powder coated RAL 7016 dark grey matt externally and RAL 9910 white matt internally as standard. External hip cappings are fitted for aesthetics and are powder-coated RAL 7016 dark grey matt to match the external perimeter frame at the base of the pyramid rooflight. Other RAL colour options are available upon request.

As standard all our lantern & pyramid double-glazed units incorporate HEATSOAKED clear low ‘E’ glass achieving a centre pane U-value of 1.1 W/m²K. Please refer to our FAQ section for an explanation of heatsoaked glass.

Delivered FULLY ASSEMBLED. No need for time-consuming assembly on site. Significantly higher security compared to kit systems.

If you require a higher level of security enhancement, we can offer a Secured By Design rooflight to suit. Please contact us to discuss your requirements.
