How To Fix Polycarbonate Sheets To A Greenhouse
See our step by step guide on how to fix polycarbonate sheets to your greenhouse.
Traditionally all rafter bars for polycarbonate sheets were timber supported - they needed to be screwed on to the top of timber bearers made of usually 3" x 2" or 4" x 2" planed softwood. These timbers would then need to be painted to match the bars and to give a pleasant aesthetic finish internally. The timbers, like all painted surfaces, need to be maintained to keep up their smart appearance. Many customers still use this option when constructing carports and lean-to roofs.
Self-Supporting rafter bars are a more recent development in the Polycarbonate Roofing industry. They are strong enough to support the roof on their own without the need for traditional timber bearers, eliminating labour and material costs and drastically reducing ongoing maintenance requirements. They are suite to the construction of complete conservatory roofs as well as traditonal lean-to's and carports.
Our Rafter-Supported Glazing Bar System is ideal for carports, lean-to's, canopies and conservatories. With this system the PVC snap cap bar is ideal for polycarbonate sheet thicknesses from 10mm to 25mm, whilst the Aluminium screw down bars suit any sheet thickness up to 35mm.
The rafter-supported system is available in brown and white and the bars are available up to 6m in length.
Our Self-Supporting Bar System is available for use with all polycarbonate sheet sizes from 16mm to 35mm. These bars are extremely strong and as a result can support spans of as much as 4m without the need for any additional purlins.
Self-Supporting Eaves beams and Wall plates form the basis of this system, enabling the complete construction of a lean-to or shaped conservatory roof in a single modular system. Bars are available in lengths of up to 6m.
Rosewood and Golden Oak options are available. Please contact us if you need more details on these products.
Sheet Edge Trims, Sheet End Closures and other accessories such as breather tape and fixings complete the polycarbonate glazing range. For a brief explanation of the various sheet and bar options available, please visit our Guides and Tips section where you can watch a short explanatory video.
