Sterlingbuild Testimonial- Aluminium Bifold Doors

grey aluminium bifold doors

Visually striking, seriously durable and extremely energy efficient, aluminium bifold doors continue to grow in popularity. Whether connecting home and garden or separating rooms internally, aluminium bifold doors have become the perfect fit for modern, eco-conscious homes that both look good and have a low impact on the environment.

One pair of homeowners and Sterlingbuild customers who recently discovered first hand the benefits of aluminium was John Barnett and his wife Brenda, who last month had internal bifold doors (pictured above) installed in their detached home in Cliftonville, Margate.

Wanting to better connect lounge and conservatory, John and Brenda opted for 5-pane aluminium bifolds that open from right to left across the entire room.

The couple customised their aluminium bifold doors with grey internal and external leafs and black hinges and handles with the exception of the opening leaf which has a graphite handle. The glazing used was standard toughened glass.

Here is what John had to say about his new internal bifold doors:

We wanted to open up the existing lounge and as this was an outside wall it needed to be suitable even though we had an existing conservatory.


Now we can enjoy the whole space, but can close up in the winter to keep warm. The doors have made a tremendous difference to the look and feel of our home.
