Are bifolds better than sliding doors?

The answer to this question will be down to the individual taste, as both our aluminium sliding and bifold doors are incredibly thermally efficient and secure. However, the aesthetics of the doors are slightly different.

Perhaps the main attraction towards our sliding doors is the more glass to frame ratio. Sliding doors have fewer sightlines, so if you have a picturesque view over the Thames from your East London flat then sliding doors will not interrupt the panorama as much as bifold doors. However, many homeowners are fixed on aluminium bi-fold doors right from the start because they want to be able to fully open their room, seamlessly blending their garden and home. Perfect for London homes with either a small garden or indoor space, bifold doors will make your home feel airier and more spacious.

Though, have you ever considered aluminium slide and pivot door? Allowing for 2, 3, 4, or 6 door panels, hingeless aluminium slide & pivot doors have reimagined the traditional bifold system by using individual sashes that function independently from one another. Large or small, this mechanism is ideal for any type of London home or apartment.

Grey aluminium doors

Grey aluminium bifold doors have become popular over the years due to how versatile all shades are, from Anthracite Grey, Pebble grey, or Slate grey, all shades complement contemporary and traditional homes.

Bifold Doors

Modern aluminium doors: are they safe?

Aluminium may be light but it is instinctively strong, and thanks to the intelligent design of our modern aluminium entrance doors, they are extremely secure. Each door is fitted with a reinforced inner frame preventing any forced entry and if your door design features glass, you will benefit from 66mm triple glazing. Giving you complete peace of mind, our glazing is PAS 24 approved, which ensures a burglar cannot gain access to your home by forcing it out of the door frame. In addition, the heavy-duty hinges are resistant to 80kg of pressure per hinge, and multi-point locking systems are fitted as standard.
