Preparing the Installation Area
Before starting the installation, carefully check all supplied components and ensure the installation area is level and structurally sound.
The guide shows how to correctly position the wall plate and front beam while ensuring the roof pitch and dimensions match your layout plan. Proper preparation is essential for achieving a secure and watertight polycarbonate roof installation.
Fixing the Wall Plate
The first step is securely fixing the wall plate to the supporting wall using suitable fixings.
The installation diagram demonstrates how the wall plate is attached and aligned to support the glazing bars correctly. Accurate positioning is critical for maintaining the correct roof fall and ensuring rainwater drains effectively from the roof.
Installing the Front Beam and Glazing Bars
Once the wall plate is installed, the front beam can be fixed into place.
The Omegabuild self supporting glazing bars are then positioned between the wall plate and front beam using the recommended fixings. The guide illustrates how the aluminium glazing bars are secured using M6 fixings to create a rigid and reliable roof structure.
For the outer edges of the roof, dedicated edge bars are used to provide a neat and weatherproof finish.
Fitting Polycarbonate Roofing Sheets
After the glazing bars are fitted, the polycarbonate roofing sheets can be installed.
The installation guide shows how each sheet is placed between the glazing bars before the top caps are clipped into position. Support trims should be cut to fit neatly between each glazing bar to ensure proper sheet support and improve the overall finish.
Correct installation of polycarbonate roofing sheets helps maximise durability, insulation, and weather resistance.
Finishing the Roof Edges
To complete the installation, the glazing bar top caps should be trimmed slightly longer than the base sections to ensure a tight fit for the end caps.
The finishing trims and edge bars provide a clean appearance while helping to protect the roof against water ingress and wind uplift.
