Four Reasons to Choose Aluminium Bi-Fold Doors

If you’re planning a home improvement project – and looking for a way to make your home in Sidcup warmer, brighter and safer – then we have some inspiring reasons for you choose aluminium bi-fold doors.

Never Too Dark

One of the key advantages of installing aluminium bi-fold doors is that you’ll feel connected to the outdoors all the time, The extensively glazed areas in your double glazing will ensure plenty of light is invited into your room. Even when your doors are closed during colder weather, your home in Sidcup will feel bright and spacious.

Access For All

When your home is busy, your aluminium bi-fold doors will reveal the true versatility of their design. The wide space your doors create when fully retracted will allow guests to come and go as they please – and without having to wait. Make entertaining easier by asking Thermaframe to install concertina doors in your home.

More Convenient

Doors that open inward make it difficult to organise the space inside a home. Furniture and other objects can’t be placed close to the thresholds, else they get knocked each time the doors are opened. Our aluminium bi-folds barely intrude; so you’ll have more control over how you organise the layout of your chosen space.

The Safer Option

Our aluminium bi-fold doors provide first class home security. Your installation will be strong enough to protect your property in Sidcup from the weather without breaking. Intruders will, in most cases, be unable to bypass the market-leading locks and hinges included as standard with your installation.
