Gas Strut vs Electric Hinged Glass Floor Hatches: Which to Choose

If you are planning access to a cellar, basement or under-floor wine store through a glass floor panel, one of the first decisions you will face is how that panel should open. Broadly, there are two approaches: a gas strut hinged hatch, which you lift by hand with assistance from the struts, and an electric or motorised hatch, which opens at the press of a button. Both can look almost identical when closed, and both can be built as bespoke panels to suit the opening. The right choice depends far more on how the space is used than on any universal rule, and requirements vary considerably from one project to the next.

This article sets out the general differences between the two in plain terms, so you have a clearer picture before speaking to a designer, architect or engineer. It is background information rather than a specification. Every opening is different, and the details for any particular project should always be confirmed with the relevant professionals.

How Gas Strut Hinged Glass Floor Hatches Work

A gas strut hatch is, at heart, a mechanical solution. The glass panel sits within a frame and is hinged along one edge. One or more gas struts sit between the frame and the panel, storing energy as the hatch closes and releasing it as the hatch opens. The effect is to offset a large portion of the panel's weight, so that what would otherwise be an unmanageable lift becomes something a person can usually handle comfortably.

Because structural floor glass is laminated and often fairly thick, these panels are heavy. Exact thicknesses vary depending on the project and are determined by a structural engineer, but the practical consequence is the same: without assistance, a glass floor hatch of any real size would be difficult to lift. Gas strut specification depends on panel size, weight, and the geometry of the opening, which is why struts are selected per project rather than taken off a shelf. A hatch that is long and narrow behaves quite differently from one that is close to square, even at a similar weight.

The appeal of the gas strut approach is its simplicity. There is no power supply to route, no control system to configure, and nothing that stops working during a power cut. Maintenance is generally limited to keeping the hinges, seals and glass clean and checking that the struts continue to hold the panel as expected. Struts do lose pressure gradually over their working life and are treated as a replaceable component, so it is sensible to think of them as something that will need attention at some stage rather than something fitted once and forgotten.

How Electric and Motorised Glass Floor Hatches Work

An electric hatch replaces the manual lift with a powered actuator. Pressing a button, using a remote, or in some cases triggering the hatch through a home automation system causes the panel to rise on its hinge and hold open until it is commanded to close. Electric systems are specified per project based on the size and weight of the glass panel, along with the geometry of the opening and how the hatch will be used day to day.

Powered hatches usually bring a set of associated features that a purely mechanical hatch cannot offer. Controlled opening and closing speeds, obstruction handling, and key or code control over who can operate the hatch are all typically part of the conversation when a motorised system is being considered. The particular arrangement varies between projects, and the safety functions appropriate to a given installation should always be discussed with your supplier and, where relevant, with your building control officer.

The trade-off is complexity. An electric hatch needs a power supply brought to the right place, which is much easier to arrange during a build or a significant renovation than it is to retrofit into a finished floor. There is also a control system to maintain, and a sensible plan for what happens if power is lost. These are all solvable, but they are worth raising early rather than late, because they can influence how the surrounding floor is built.

Comparing the Two: Practical Considerations

Frequency of use is often the deciding factor. A hatch that is opened occasionally — seasonal storage, a rarely visited service void, a cellar used a few times a year — tends to suit a gas strut arrangement well. The mechanism is simple, robust, and entirely adequate for the demand placed on it. A hatch opened several times a week, by contrast, gradually makes the case for automation, simply because the repeated physical effort becomes a genuine consideration.

Who uses the hatch matters just as much. A household where everyone is comfortable lifting a counterbalanced panel has different needs from one where accessibility is a concern, or where the hatch sits in a commercial setting used by a range of staff. Powered operation removes the physical demand almost entirely, which can be the difference between a feature that gets used and one that quietly stops being used.

Budget and programme are the other practical constraints. A motorised system carries a higher cost than a manual one, both for the mechanism itself and for the electrical work around it. If you are weighing this up, our general glass floor pricing guide gives an idea of the factors that influence cost across different types of installation.

Which Option Suits Your Project?

In our experience, the projects that go most smoothly are the ones where this question is settled early, before the floor build-up is finalised. Retrofitting power to an existing opening is possible but rarely straightforward, so if there is any prospect of wanting a motorised hatch later, it is worth at least running a supply to the location while the floor is open.

For manual installations, our hinged glass wine cellar door and basement floor hatch is the usual starting point, built to the dimensions of the opening rather than to a fixed size. Where powered operation is preferred, our electric hinged wine cellar door covers the motorised equivalent. Both are made to order, and in both cases the specification follows from the opening, the loading and the way the space will be used rather than the other way around.

If you are unsure which direction to take, it is usually more productive to describe how you expect to use the space than to arrive with a mechanism already chosen. We aim to talk through the options honestly, including the cases where the simpler solution is the better one.
