What is a lantern roof extension?

A lantern roof is a roofing system formed of glazed panels that are fitted at an angle, where a flat roof would normally lie. Pieced together with sleek aluminium or uPVC panels, it acts as a stunning centrepiece for any home extension. They’re popular with homeowners looking to retain their privacy, yet let the natural light brighten the room. Our roof lanterns are made to measure, so you can incorporate as many opening windows as you require to maximise ventilation capacity.

    Lantern roof extensions can withstand even the harshest weathers

    Both modern uPVC and aluminium offer incredible levels of durability, giving you peace of mind that your new lantern roof will offer incredible sturdiness. They’ve been rigorously tested to meet strict industry standards, ensuring they won’t smash or weaken over time.

    The innovative structure features fewer bars so they can hold extra glass, heightening its structural integrity whilst increasing light intake. We also incorporate a triple layer storm shield protection, so it can withstand tough winds of up to 130mph and heavy rains. This pioneering design also eliminates any sounds of rain, providing a relaxed atmosphere inside.

    Enhance your conservatory interior décor with insulated pelmets

    Internal pelmets can border the perimeter of the room to give the illusion of a flat ceiling which borders the roof lantern. Not only will this direct all attention towards the raised glass roof, it also improves its thermal performance. This is because it’s fitted with mineral wool insulation.

    The size of the internal pelmets can range from 300mm to 1200mm, depending on your ideal indoor aesthetics. They can be plastered and painted in an array of colours to complement your home’s current interior design.

    Another great benefit of including contemporary pelmets is we can add spotlights and downlights inside the room to provide a glowing ambience that allures a luxury flair. We can even install speakers for a surround sound system that will provide the perfect space to entertain friends and family.

    Keeping energy bills low across Tonbridge, Rochester and Canterbury

    We use our A+ rated double glazing which utilises innovative techniques to retain the warmth inside and keep the draughts out. The glazing panels can reach U-values of 1.1, which is higher than building standards. During the summer, they actively eliminate the sun rays from entering and causing your extension to overheat. This intelligent design ensures your glass extension will keep at an optimal temperature all year round. Our modern design also includes insulated under cladding and eaves rails, keeping the cold elements out.

    Our lantern roofs can be fitted with solar control and roof vents, helping you to regulate the internal temperature all year round. Our advanced glazing also boasts self-cleaning abilities, so you won’t need to worry about continual upkeep to ensure they look and perform as good as new. With less frame and more sky, you’ll be able to enjoy your extended living area all year round.
