It is always relevant to consider patio doors alongside bi-fold doors when looking for a large area of tall glazing and a better access to the outside space.

Bi-folds have become a popular choice for most modern conservatory and orangery projects, but can be expensive when you add in the structural requirements and then consider aluminium as the preferred option for structural strength and lifespan.

So it is worth considering the benefits of patio doors as a viable practical and lower cost alternative, with spans of up to 6 metres possible with some upvc ranges such as Kommerling. The other advantage is that there are no doors to accomodate in the internal or external space . Another advantage is that they are quite robust and well tested over time with fewer structural failures under stress compared to upvc bi-folds.

large spans no problem

Lift and Slide Patio Doors - The Lift and Slide patio door is a genuine alternative to a bi-folding door and with less PVCu sightlines, also with more glass in which to see the world outside. The product is designed for large openings in the home or conservatory and is capable of openings of up to 6 metres with just two sashes.

There’s also the option of 2, 3 and 4 pane door systems which are capable of spanning over 10 metres. The running track has been specifically designed for lasting performance and ease of use. There’s also a thermally broken frame that provides energy efficiency and the necessary structural integrity to carry a large sash with ease. Like all of our window and door systems, it’s extruded with lead-free Greenline compound.

The Kommerling PremiLine sliding patio door is packed with technical features and is extruded using Greenline lead-free PVCu compound. This is in our view a well priced and practical answer for most large opening situations.

Premline is also the perfect match to the C70 and O70 upvc frame systems and given the innovative design of the outer frame which is 70mm deep tapering out to 80mm to accommodate the sash, it can be easily coupled to any Kömmerling 70mm frame, and benefits from a large range of ancillaries.
