Structural Guidelines for building your Self Supported roof
You need to consider the strength needed in your self supporting glazing bars when you are building a Self-support roof as you cannot rely upon wooden rafters to provide any structural strength.
The following chart shows the centres for Self Support Glazing bars for glass or polycarbonate conservatory roofs. You also need to bear in mind the restrictions on the sheet widths as below.
For a glass roofed canopy (or other open structure) we would recommend keeping the centres of your self support glazing bars at around 500mm even for smaller projections. If in doubt check with your glass supplier.
Maximum polycarbonate sheet widths by thickness
The following are our conservatory roof guidelines for maximum centres based upon each polycarbonate sheet thicknesses. The centres of the self support glazing bars in the above chart may in some cases be bigger than those given for the sheet thickness. You must not exceed either the centres recommended for the bars or those for the thickness of the sheets, always go to the smaller of the two. For example: As you can see here you could glaze your 3m projection roof with 25mm and upwards of polycarbonate but 16mm would be restricted to 900mm centres. For a self supporting roof on a canopy we would recommend keeping the sheets no more than 900mm for all thicknesses.
We also supply a full range of accessories for your self support roof, from wall bar adapters to sheet end closures to complete your project. We also have gutter clips that fit onto the eaves beam without the need for screws.
If you roof is polycarbonate, we supply all thicknesses of multiwall polycarbonate at highly competitive prices. We cut it to size for you at no extra cost so you only pay for what you use.
