Polycarbonate is a very popular material for roofing sheets. It’s stronger, lighter, and far more durable than glass. It can even be cut to size with a circular saw. However, sometimes the panel sizes available do not meet the needs of the task at hand. When this happens you’ll need to find a way to join the various sheets together.
Multiwall
To join two sheets of multiwall together you can use an H section. For instance, the Snapa Polycarbonate H Section can be used to join two sheets of Axiome – either 6mm, 10mm or 16mm. These H sections are very discrete thanks to actually being made of polycarbonate themselves, which helps them resemble just part of the polycarbonate sheet unless carefully examined.
The Snapa Polycarbonate H Section is best when you want to add some extra size to an otherwise more modest installation like a lean-to or pergola. This is why they’re technically part of the Snapa brand which is geared towards small garden features.
For a more robust join, there is also the ALUKAP-XR Aluminium H section. This is made of aluminium. While it’s more obvious than the Snapa option, its rigidity and strength can more than make up for that.
The ALUKAP-XR Aluminium H Section is better suited for when you need better span on more established structures. You’d expect to see the ALUKAP-XR Aluminium H Section on a conservatory or orangery.
Glazing Panels
When you’re installing your polycarbonate glazing using Sekosnap you have access to not just the outer frame but also the Sekosnap H Connector. Sekosnap is a secondary glazing system for Clear Amber’s Axgard glazing panels. The H Connector lets glazing panels be connected on a long window.
This is particularly useful if you are installing double glazing on long horizontal windows. Since the double glazing needs to cover the entire window in one go you can’t just have separate fully framed Sekosnap panels, they need a connector.
Whether you’re using H Sections or H Connectors, you need to make sure that you take the additional length into mind when planning your design. It’s not the same as just having two sheets adjacent.
