Laserlite Multiwall Gasket End Cap 10mm (10m Roll)

The Laserlite Multiwall Gasket End Cap is the sealing strip that runs along the open ends of a 10mm multiwall polycarbonate sheet. A multiwall sheet has open air-core flutes at each end, and if those flutes are left open, dust, moisture and insects get inside the panel and the insulating air-core is compromised. This gasket seals the sheet ends and keeps the panel performing as it should.

The gasket is made from a flexible, durable material that accommodates the slight variations in panel size and shape you get on site. It is applied along the open edge of the sheet before the panel is fixed in place, and it is supplied in a 10 metre roll so you can cut it to the exact length you need for each sheet.

It is a small accessory with a big job. Sealing the ends of a multiwall sheet is one of those details that separates a roof that stays clean and warm from one that gradually fills with dust and loses its insulating value.

What You Need To Complete The Job

The gasket end cap is one of the three key accessories for a multiwall roof, along with the aluminium H bar that joins the sheets and the edge bar that finishes the exposed edges. It is used with Laserlite Multiwall sheets. The full range of profiles and accessories is in the Laserlite Multiwall category, inside the wider Polycarbonate Roofing range.

Frequently Asked Questions

Why do multiwall sheets need an end cap?

A multiwall sheet is built as a series of air-core channels between two skins, and those channels are open at each end. The gasket seals the open ends so dust, moisture and insects cannot get inside the panel and reduce its insulation or clarity over time.

Which sheets does it fit?

It is designed for 10mm multiwall polycarbonate sheets, which includes the 10mm Laserlite Multiwall panels sold at Singh Roofing Supplies. Check the sheet thickness before ordering to confirm it matches.

How much do I need for a job?

Measure the total width of all the sheet ends you need to seal and add a little for waste. A 10m roll covers a typical veranda or small roof; order a second roll for a larger area.

Is the gasket easy to install?

Yes. It is applied along the open edge of the sheet before the panel is fixed in place, and its flexible nature lets it follow the panel. Trim it to length with a knife or scissors on site.

Does it work with the H bar and edge bar?

Yes. It is part of the full multiwall accessory set: the H bar joins sheets, the edge bar finishes exposed edges, and the gasket end cap seals the sheet ends. Use all three for a complete installation.
