Roof Glass Thickness

These beams are toughened and laminated and your structural engineer will calculate the size and strength they need to be.

Roof glass thickness.

Typical table top glass thickness is the same from 1 4 to 3 4. We use only high quality tempered glass. Other types of shingles including number 1 wood cedar shake and tile are thicker although the thickness depends upon the individual brand of shingles you select. For heights up to 5 m above floor level toughened glass can be considered if the other glass products cannot be used.

Each individual piece of glass could end up needing to be as thick as 2cm. Over 13 m above floor level toughened glass is not recommended. When installed however the shingles overlap doubling the thickness. However with the current trend for flat rooflights single pane rooflights can be installed up to 3m x 6m in one pane of glass.

Despite its brittle nature glass is an enormously strong material. In summer you may enjoy the freedom on the terrace or in an additional living room. The thickness of the glass and the integrity of the insulating glass unit therefore must be considered. Standard asphalt shingles add very little thickness to the roof because a standard three tab shingle is about 3 16 inch thick.

In our projects we usually use glass thickness from 1 4 to 3 4 for shower doors. The terrace looks much more cozy and friendly. The vast majority of roof lights on the market rely on 2 toughened glass panes however at eos we feel a minimum outer pane of 8mm toughened and 8 8mm inner pane of laminated glass offers significant safety and security benefits. The most economic glass tends to be 4 6mm thick which rarely can be installed wider than 1000mm hence most domestic roof lantern and conservatory installation featuring glazing bars every 600 to 900mm.

In fixed and opening roof lights 4mm thick glass is just not sufficient and you should insist on 6mm in any glazed roofing product. The glass roof for the patio has several advantages compared to other conventional patio roofs a transparent roof allows the sunlight to flood the interiors. Between 5 m and 13 m above floor level restrict the toughened glass thickness to 6 mm and 3 m2 in one pane. Thickness of glass railings and wall systems varies from 3 8 to 3 4.

Under compression loads a 1cm cube of glass can withstand up to 10 tonnes before breaking.
