Aluminium Windows and Bifold Doors Belfast

These beautiful aluminium windows and bifold doors were recently designed and installed by the Designer Door Company in Belfast, working closely with our client’s chosen builder.

Aluminium Bi Fold Doors

The three leaf black aluminium bifold doors open up onto the new patio, allowing seamless integration of this beautiful family home and garden.

These robust doors offer a sleek and elegant appearance with their ultra slim profiles, allowing a larger glazed area to flood this new home extension with plenty of natural light. 

The three pane option allows a functional traffic door, while stainless steel rollers add strength and allow smooth, easy operation.

These beautiful aluminium doors are not only child friendly, they also have multi-point locking systems in several places.
This gives you complete peace of mind with the built-in enhanced security features. 

Aluminium Roof Lantern

The black aluminium roof lantern is an ultra modern, robust and stylish alternative to uPVC.
High grade, lightweight aluminium is used with extra secure glass support, offering optimum strength and security.

Toughened, self-cleaning glass with built-in solar reflection allows natural light to flow into the room from every angle, whilst reducing harmful UV rays.

Especially suitable for flat roof extensions or orangeries, these low maintenance roof lanterns are available in a range of design options, and sizes of up to 4.5m!

Aluminium Window

A black aluminium window was chosen to match the bifold doors and roof lantern.

Stainless steel friction hinges allow smooth and silent operation, and multi-point locking features add to the enhanced security of our clients new room.

Our stylish and energy efficient aluminium windows and doors use high grade and lightweight aluminium as standard.

Unlike timber or PVC, aluminium is a stable material with minimal expansion and contraction.
These frames won’t warp, twist or expand with changing temperatures.

These beautiful windows and doors surpass all current thermal regulations, and are certified under the ‘secured by design’ scheme.

Custom powder coating is applied across our entire aluminium window, door and roof lantern ranges.
This not only offers full customisation of the frames with available RAL colours, it also ensures resistance to erosion and fading.
This added protection can extend the life of the aluminium windows and doors, especially in coastal areas, and will withstand all weather conditions in Northern Ireland!
