Roof Lanterns


Roof Lanterns Northern Ireland.

At the Designer Door Company, we provide different types and sizes of skylights, rooflights and roof lanterns suitable for installation into a pitched or flat roof

Roof lanterns are designed to capture more natural light with their angled glass panes, and can make a room feel more spacious by adding height.
Providing stunning views of the sky, especially at night, we can create custom roof lights in any colour  to maximise your enjoyment of the great outdoors whilst complimenting the aesthetics of your property.

Aluminium roof lanterns offer a high strength-to-weight ratio, allowing much larger glazed areas with slim, sleek frames.With the longest longevity of all roof light materials, these contemporary aluminium frames are virtually maintenance free with enhanced durabilities and unrivalled strength.

As aluminium is considerably more erosion resistant to the elements, our dual layer, powder coated frames will perform extremely well in all weather conditions in Northern Ireland.

We use thermally broken aluminium frames with a polyamide core, which offer outstanding insulation performance. These modern roof skylights are thermally efficient and allow an added layer of insulation, helping to provide long term savings on heating costs when compared to single glazed or timber framed roof lanterns. 

Multiple high performance glazing options are available, with blue activ glass fast becoming the most popular choice.
This option can help to maintain a consistent internal temperature due to the solar control performance, whilst bathing the room below in light.

An additional surface coating offers self cleaning properties, which is ideal for use in hard to reach areas. 

Argon gas filled glazing boasts a stronger resistance to ‘furniture fading’ ultraviolet rays.
Offering an extra layer of anti-fade protection, our high performance glazed units with a low-E coating can help protect your furnishings and art work from sun damage, in turn saving money on replacements. 

High strength and flame retardant, our robust skylights offer an additional layer of security for your home.

High Performance, Approved Materials.

Especially suitable for period properties, the materials used in our sky lanterns are approved for use by local planning authorities where heritage roof lights are a must. 

With the longest lifespan of any roof lantern material, aluminium framework can contribute towards protecting fragile buildings as this minimises the amount of times frames will need to be replaced. 

An architectural elegance can be created with aluminium skylights, such as a more sleek, contemporary showpiece for style conscious homeowners. 

Make a grand first impression with serious kerb appeal, and increase the value of your property too!
