Laserlite Multiwall Accessories for Polycarbonate Sheets:

A great polycarbonate roofing project doesn’t stop at the panels, it’s the accessories that make the difference. At Blacktown Building Supplies, we stock the full range of Laserlite Multiwall accessories to ensure your installation is secure, weatherproof, and finished to a professional standard.

Whether you’re working on a pergola, patio, carport, or custom polycarbonate cladding, the right connectors, capping, gaskets and sealants are essential for structural performance and long-term durability. These components are specifically designed to match Laserlite Multiwall polycarbonate roofing systems for a clean, watertight result every time.

What’s in the Laserlite Multiwall Accessories Range?

Our multiwall accessory range includes purpose-built components that make installation faster, easier, and more reliable.

H-Bars (One Piece and Two Piece)
Designed to connect adjacent polycarbonate sheets, H-Bars create a strong, flush joint between panels. Available in aluminium one-piece and two-piece systems, they help secure sheets in place while allowing for thermal expansion.

Edge Bars
Edge Bars finish the exposed sides of your multiwall sheets, protecting the internal cells from water, dust and UV damage. They provide a neat finish and structural stability at the perimeter of your roof.

End Caps
Seal the open ends of your polycarbonate sheets with aluminium end caps for added rigidity and weather protection. These work alongside gaskets to create a waterproof seal and reduce wind ingress.

Breather Tape
This self-adhesive tape allows trapped moisture to escape from the sheet’s internal flutes, preventing condensation buildup and mould. Breather tape is essential for sheet longevity, especially in shaded or enclosed areas. 

Sealing Tape
Seal the top ends of multiwall sheets with high-adhesion sealing tape. It blocks dust, insects, and water from entering the flutes, and complements breather tape for full protection.
