Upgrade your glazed extension roof to a bespoke lantern roof

Aluminium is the modern ‘material of the moment’, so it makes sense to shape it into an innovative fully thermally broken lantern roof system for glazed extensions. Allowing more light & warmth into any extension space it’s applied to, the Stratus lantern roof is the ideal solution for families who want a space that stays cool in summer & warm & cosy throughout the long winter months.

Available in 2-way, 3-way, or modern design models that allow lantern sizes up to 3m x 6m, this is an exclusive high-end & high-performance extension roof that truly pays for itself. Another bonus is that it’s incredibly quick & easy to install too; ideally accommodating the hustle & bustle of family life.

Key features

Energy efficiency

We believe this to be one of the best roof lantern models on the market; let’s explain why! As an innovative thermally broken aluminium roofing system, our lantern roof is designed with exceptional thermal efficiency in mind. Able to achieve U-values as low as 1.0 & (up to) 65% more thermally sound than typical aluminium roofing systems, it cleverly utilises polyamide nylon, glass composite thermal breaks which are 533 times more efficient than aluminium!

Safe & secure

Lightweight, hardwearing & incredibly watertight & weatherproof, our lantern roof complements both classic & contemporary building projects alike.

Decorative options

Apply the final finishing touch to your new Stratus lantern roof with a choice of two durable exterior powder-coated finishes; classic Crisp White (RAL 9016) or alluring Anthracite Grey (RAL 7016).

A service you can rely on

"Doors & Windows ( Exeter) have provided a first class service from start to finish. Nothing was too much trouble and when it came to a small problem it was sorted immediately without any hesitation. I would thoroughly recommend Nick, Rob and the team. It’s so pleasantly refreshing to find a company who put their customers first. Thank you."

- Lisa S. 5

"Through a recommendation, I popped into the office to see if they could help me source a new door handle. Nick was extremely helpful and ordered one for me through a company they use. I will certainly recommend the company to family and friends and I will use them for replacement windows and doors in the future. Many thanks for the free tin of silicone spray!"

- Sue M. 5

"Brilliant local company. Installed a new door for my father (after a recommendation by a friend). Great product, great price, but (& I can not stress this enough) their kindness & care dealing with an elderly gent, especially regarding the guarantee (so both myself as his son & he could have a copy) was amazing. I genuinely did not believe service like this existed any more. Lovely people to do business with & a company I can thoroughly recommend."

- Ashley D. 5

"Excellent delivery of service and installation (11 windows and 1 door). Thank you Tom for a job well done! Clean and very efficient. We were recommended by word of mouth to use Doors and Windows and would not hesitate to recommend this company ourselves. Many thanks."

- David G. 5

"Cannot fault customer service in anyway from this firm we called in reference to get a quote to replace some windows. Nick came out the same day was very helpful with ideas and suggestions of what types of windows that would suit and with 24 hrs a quotation was waiting in my inbox. We shall be almost certainly be putting an order in shortly. Cannot recommend this company more highly to anyone thinking of new windows or doors should definitely give Nick a call."

- Terry Bowen 5

"Nick and his team fitted some new doors and windows at the back of our lean to. The service from start to finish was excellent and the new doors and windows make the lean to look like a new room! Would highly recommend."
