What is a lantern roof conservatory?

A Lantern roof combines a collection of angled glazed panels that normally surround a flat roof, creating a glass focal centre. With a thermally broken aluminium or uPVC cluster, they provide superb thermal insulation. With solar control and self-cleaning glass, you never have to worry about losing any of the room’s warmth, as it will absorb the heat of the sun. This could even save you money on your energy bills!

    As they are designed with our high-quality aluminium or uPVC materials, you will benefit from industry-leading levels of robustness with your sturdy lantern roof, meaning leaks and draughts are eliminated. Our inventive structure incorporates fewer bars, meaning they can hold extra glass. Not only does this mean they’ll let in more of the sunlight, they’re structural integrity is improved. Both materials utilise modern manufacturing techniques and a triple layer storm shield protection to maximise their strength against snow, strong winds of up to 130mph and heavy rain. Passing strict industry tests, they have been proven not to bend, smash or deteriorate in quality over time.

    A premium looking and performing interior with insulated pelmets

    An internal pelmet borders the perimeter of the room, giving the impression of a flat ceiling that frames the roof lantern, making it the focal point of the extension. The framing system is fitted with mineral wool insulation, meaning it will reduce heat loss and keep the room a comfortable living temperature all year round.

    Its size can be tailored to your conservatory or orangery, ranging in widths from 300mm to 1200mm, providing the contemporary appearance of a full extension with it’s sleek and clean lines. It can be painted in an array of colours to match your interior scheme. The beauty of incorporating pelmets into a lantern roof extension is that spotlights and downlights can beautifully light up the border of the room, giving the illusion that it’s larger than it is and provides a contemporary feel. Speakers can be installed into the internal pelmet for a premium surround sound system for a bespoke modern extension.
