The calculation of design wind loads on a roof is an essential part of the design process. The designer must ensure that the installed roof system is able to resist the wind load induced by a building’s geometry and location and that the correct calculation procedures are followed. The correct calculation methodology for UK BuildingRead more

Membrane lined gutters have now been used in the roofing and cladding industry for many years. These can be in the form of single skin, insulated and composite gutter systems. When designed and installed correctly membrane lined gutters provide a secure watertight gutter solution especially at the gutter joints which historically have been the weakestRead more

The use of 1.8mm + thick PVC membranes is normally a requirement on extended 20 and 25 year guarantees. The theory behind is that it should last longer as it has a larger volume of plasticiser and more robust due to its additional thickness. Whilst I would not disagree with this theory, I would pointRead more
When many people think of specifying or using single ply membrane roofing systems, they look at the waterproofing membrane, thermal insulation, VCL type etc. without considering what type of roofing ancillaries they need. However do you always think of the smaller items which can be the glue that (quite literally) brings the system together? AfterRead more
Over the last couple of decades we have seen a steady increase in thicknesses of insulation being used in construction. This has, however, had an impact on design in both the new build and refurbishment sector. In terms of the thermal design of a flat roof, what are the options and the best practices ofRead more
