The set-out dimensions of the Ultrasky roof lantern are measured to the external wall of the timber kerb, 150 mm high x 70 mm wide (not supplied), and NOT the size of the cut-out in the flat roof.
In most cases therefore the dimensions of the lantern are calculated as follows:
Length = Length of hole + (2 x Kerb Width)
Width = Width of hole + (2 x Kerb Width)
Hole 1000mm x 1500mm
Kerb Width 70mm
Overall Dimensions of Lantern: 1140mm x 1640mm
Our roof lanterns are manufactured on demand and therefore we can offer bespoke sizes, should a specific size be required.
Roof Lantern Kits – Ultraframe Ultrasky Skylights
Roof lanterns are the perfect finishing touch for an extension, orangery or any flat roof in your home. Elevated glazed panels let light fill your room while giving you a beautiful centrepiece that will always impress. They’re the perfect choice if you don’t want a fully glazed roof but still want to enjoy a light filled and bright home.
Here at Spectrum Glazing, we are delighted to offer you two stunning roof lantern options: Ultraframe’s UltraSky and Synseal’s Stratus roof lantern. Let’s take a look at what they can offer your home.
Both roof lantern systems are made of aluminium, a material certain to push your home into the 21st century. With a modern look as well as performance, aluminium is exceptionally strong. This makes it the perfect choice for a roof lantern as it can hold large glass panes without needing bulky frames.
The Stratus roof boasts a 66% smaller ridge than other systems to give a beautiful aesthetic. The UltraSky has bars that are four times stronger which means you can enjoy more light compared to frame. They’re strong enough to hang a chandelier to add that touch of elegance to your home.
Keep your home insulated and warm all year round
Aluminium is a fantastic insulator so you don’t need to worry about losing heat through your new roof lantern. Both roof lantern systems have thermally broken frames which prevent cold air transferring to the inside of your home. The UltraSky roof lantern has an innovative protection system which gives it added water and weatherproof qualities ensuring it never lets you down.
With u-values as low as 1.1 achievable, the UltraSky will keep your warmth in all year round. The Stratus roof lantern system with polyamide nylon glass composite thermal breaks claims to be over 500x more efficient than aluminium alone. This makes it the perfect choice if you want a room to use all year round.
Beautiful focal points to add the wow factor
Roof lanterns fit perfectly into any style of home and you have options when it comes to personalising them. The Stratus roof lantern can be made in powder coated Crisp White or Anthracite Grey. The UltraSky roof lantern comes in White, Anthracite Grey or Satin Black. Whether you want your roof to stand out or blend in with the rest of your home, one of these colours will be perfect.
Choose white if you want a more classic look or grey for a touch of modern sophistication. Both can be made in custom designs with the Stratus available in contemporary two or three-way designs and can be made up to 3m by 6m. The UltraSky can be made in custom configurations up to 2 by 4m.
