Introducing Quick-Glide Invisifold Slide and Turn Doors: A New Option for Your Home

We’ve added the newest generation of slide and turn doors to our range. More specifically, the Quick-Glide Invisifold system. This is a latest generation aluminium door that might look like a bifold when it’s closed, but works very differently once you start using it.

Quick-Glide Invisifold Slide and Turn. A better bifold door experience.

Also known as Invisifold, Quickslide is an excellent solution if you’re planning a new kitchen extension, replacing tired patio doors, or opening up the back of your house.

The slide and turn design of these doors, can actualy offer more functional benefits than a bifold, so it is worth getting to see both products side by side. Slide and turn doors sit somewhere between the two, and for some homes, they’re the better choice.

At LB Window Systems, we’ve been installing high quality bifolds for years. They’re excellent doors when specified correctly, and we’ll continue to fit them. But we’ve been asked about slide and turn doors often enough now that it made sense to offer them properly.

Once you understand how they work, you’ll see why they appeal to people who want the full opening width of a bifold without some of the compromises.

How slide and turn doors actually work

The panels aren’t hinged together like a bifold. Each one moves independently. You unlock the main door at the end, swing it open, then slide each panel along the track one at a time. As each panel reaches the end, it swings open and stacks neatly alongside the one before it.

When they’re fully open, you get around 90% clear opening, just like a bifold. When they’re closed, they look almost identical. The difference is in how you use them day to day, and that’s where the benefits start to show.

1. More usable space inside and out

Bifolds need swing space. When you open them, the folding panels take up room, either inside when they fold in or outside on your patio when they fold out. That means you have to leave a clear zone, which limits where you can put furniture, or where your table and chairs can sit outside.

With slide and turn doors, the panels move along the track first before they pivot open. You slide them all the way to the end, either left or right and then hinge them outwards.

The immediate benefit of slide and turn doors vs bifold doors is you can place furniture right up against the doors, inside or out, without blocking their operation. If space is tight in your extension or your patio area isn’t huge, that makes a noticeable and practical difference.

2. Better ventilation without fully opening the doors

Bifolds are either closed or fully open. Yes, you can prop one leaf open such as a traffic door, but it’s not always ideal.

With slide and turn doors, you can open the main leaf, then slide just one or two panels across to create airflow through your home without exposing the whole opening. On warm days when you want air movement but don’t need the doors fully back, it’s a more comfortable way to use them.

3. Cleaner sightlines with no visible hardware

Because the panels move separately, there are no connecting hinges down the length of the door. And because the panels move independentoy thgere are no internal pull handles or locking handles either. When you look at a closed set of slide and turn doors from inside or outside your room, you see clean vertical lines and glass. That’s it.

A further benefit is some obscure and lower quality brands of bifolds are difficult to get parts for when these internal handles need servicing, repair or replacment.

From the outside, the same applies. Fewer visible fixings, fewer potential weak points, and a noticeably sleeker appearance. If you’ve ever found bifold hardware a bit fussy or visually cluttered, this is a quieter, more refined alternative.

4. Wider panels, fewer door leaves

The Quick-Glide Invisifold panels can be made up to 1150mm wide. That’s wider than most bifolds, which tend to stop around 1000–1200mm. It means you can sometimes get away with three panels where a bifold would need four.

One less panel means one less vertical line interrupting your view, larger glazed areas, and a more open feel. It’s a small difference on paper, but it changes how the doors sit in the room.

What you get with Quick-Glide Invisifold

The system uses premium grade polyamide thermal break aluminium with a slim 114mm sightline at the door panels – noticeably slimmer than many bifolds. The panels glide on self-lubricating pads rather than rollers, so there’s less to wear out or maintain over time.

Security is covered by a multipoint locking system with a high security cylinder. PAS 24 upgrade is available if you need it for Building Regulations or insurance purposes. Trickle vents are flush-fitted and meet current ventilation requirements without looking obvious.

You have a choice of black, anthracite grey, or white externally, with the option of white on the inside if you want a dual colour finish. Handle finishes include white, black, chrome, anthracite grey, and satin.

Glazing is 28mm double glazed as standard, with triple glazing available if you want to push the U-value down to 1.3 W/m²K. Laminated or obscured glass options are there if needed, and integral blinds can be fitted between the panes.

The doors open outwards, left or right handed depending on your layout. You can specify anything from two panels up to nine, covering openings from around 1.2m wide up to over 10 metres if required.

When slide and turn doors make sense

They suit homes where space matters. Smaller gardens, compact extensions, tighter internal layouts. They’re ideal if you value clean aesthetics and want fewer visible fixings. They work well if you’re likely to use partial ventilation regularly rather than throwing the whole door open every time. But they’re also great for larger patios and gardens. It’s the functional difference between these and a bifold you need to consider.

They’re no faster to operate than a bifold, even though you’re moving each panel individually rather than pushing a connected set.

Some people don’t like gripping the edge of the glass to slide the panels, and slim doors do show fingerprints more readily. Those aren’t deal-breakers for most, but they’re worth knowing about.
