Trusted Window Installers in Boston

The Blade rooflight is incredibly strong. Our infinity top glass pane is a substantial up to 10mm thick as opposed to other roof window manufacturers who supply cheaper and weaker 4mm or 6mm glass. All exposed glass edges are polished for rooflight aesthetics and this also makes them less prone to cracking.

Ofset love to build relationships with architects, developers, designers and construction companies. Please contact us to discuss possibilities of using our beautiful rooflight system in your latest projects.

We ask for a 50% payment on placing the order, then the final 50% normally 3 working days prior to delivery once the rooflights are manufactured, checked, packed, wrapped and good to go.

We offer a 24 hour cooling off period. After that time, it is impossible to cancel your order. You have ordered a bespoke roof window product which is being made to your personal specifications and once the manufacturing process has begun and your frames are cut, we cannot make changes or offer refunds for cancellations.

Apologies. We are the victims of own own desire to please, offering the widest choice of rooflight designs and options in the industry. In addition, all our rooflights are bespoke and made to order.
