The original Conservation Rooflight remains unsurpassed as a high spec design with a traditional look.  Designed to faithfully replicate the Victorian case iron roof window, it combines modern thermal efficiency with all the authentic design features to retain the character and value of any heritage or listed property, meeting all current building regulations. It satisfies conservation officer, English Heritage and National Trust requirements.

Key features include slim clean lines internally and a low profile to match the roofline, glazing clips and top hinged opening to maximise space and ventilation.  There are three different linking bar options to provide the opportunity for an unlimited run of Conservation Rooflights providing maximum natural light.

The unit achieves whole-unit U-Value of 1.5Wm2K in accordance with EN ISO 10077-2:2012 and is fitted with a unique Thermoliner feature which controls condensation.  The standard frame is finished in a textured semi-gloss paint finish in black RAL 9005 to keep that authentic look.  The roof windows can open manually or be fitted with a motor, controlled by a switch or remote control.

There is a choice of sixteen standard sizes with excellent ongoing availability. We also offer a made to measure service to avoid cutting existing rafters thereby preserving the integrity of any historic building. Alternatively, collaborate with our in-house design team to create a bespoke rooflight for your design.
