107mm Slim sight lines as standard

Ultra-slim aluminium bifolds - 107 mm sight lines

Ultra-slim aluminium bifold doors are equipped with features that make them exceptionally aesthetically pleasing and energy efficient while also giving your door added security.

There is so much to customise and choose on these doors as well that won’t affect any of the reliability and strength that the doors have. These options include the exact size of the doors, the glass type, colours and finish that they have.

Getting an ultra-slim bifold for your door will make any home look even better, especially with the high-quality hardware used in production.

Like all of our aluminium bi-folding doors, the ultra-slim aluminium bi-folds come with a variety of qualities like integral glass Venetian blinds, Ultion 3-star anti-snap locks as the standard for entries and a selection of optional extras to add to your ultra-slim doors.

Ultra slim 107mm sightlines as standard

Ultra-slim aluminium bi-folding doors aren’t the only kind of bi-folding doors we sell, as there are a variety of others to choose from, where you can pick the exact number of panels and size of your doors.

The most popular choices are 5-panel, 4-panel, and 3-panel aluminium bifold doors, which are excellent installations for any property.

For the panels in the bifolding doors, there are double glazing and triple glazing options, along with the addition of heritage style bars and integral blinds in a range of RAL and standard colours to suit any home.

Getting your doors double or triple-glazed adds more energy efficiency to a property with its increasingly low U-values.

You can get patterned and solar control glass for your aluminium bi-fold doors.

Why get ultra slim bifold doors?

Ultra-slim aluminium bifolding doors are mainly purchased due to their aesthetic look, as in general slimmer sight lines on bifolds look better than thicker ones, such as 140mm.

Natural light and an unblocked view are just some of the benefits of slim frames and sight lines to our standard aluminium bi-folds. These will make them highly energy efficient, which can help to lower energy bills.

A multi-point lock system is the standard for our 107 mm ultra-slim aluminium doors, providing them with extreme security and sturdiness.
