Frequently Asked Questions
Bi- Folding or sliding patio doors - which is better?
Choosing between these two doors types depends upon your taste, preference, and home requirements. We recommend sliding patio doors if you desire having the largest unbroken view of your garden or countryside, with flowing access in and out.
These doors come with bigger glass panels, thus providing better light transmissions and better views. They are widely known for creating “glass walls”, a popular design in modern homes.
However, unlike sliding patio doors, bi-fold doors can be opened up almost entirely, folding away to leave a large open space between the inside and outside of your home.
Both styles have their benefits and both are great choices.
What materials are your patio doors made up of?
It completely depends on what you are looking for. However, aluminum and uPVC materials are popular choices. That’s more because:
● Both these materials are extremely durable and affordable.
● They are available in an extensive range of colors.
● The door frames made up of these materials give a modern look to the property.
● They are very durable and long-lasting.
● They involve low to no maintenance.
● Thanks to advanced measures such as glazing; these doors are highly energy-efficient.
Are your sliding patio doors secure?
Yes absolutely, both our aluminum and uPVC sliding patio doors in Belfast are designed with multiple advanced hardware to ensure heightened security. Here are the amazing features of our patio door products:
● Multiple points locking system
● Internal beading

Our patio doors offer higher levels of safety as they exceed PAS24 hardware as well as governmental “Secured by Design” standards.
