Join us at RIBA’s CPD Roadshow in London on 24th November where Martin Gleeson, Technical Specification Manager for Central London, will be presenting our new CPD titled ‘The New Approved Document L: Effects on The Specification of Rooflights and Roof Glazing.’
Predominately an ‘in plane’ rooflight is a rooflight that is in plane (by which we mean Flush) with the rest of the roof that it sits on. An in plane rooflight doesn’t require any changes to the pitch of the roof, for example a Velux roof window. Other examples would be polycarbonate or GRP sheeting […]
When specifying rooflights or roof windows, the first thing you’ll probably think about is how the items will look once they’re installed. This is certainly an important aspect to consider – after all, appearance is critical. But you will also need to analyse the performance criteria of these glazing units to ensure they serve their […]
Most modern contemporary rooflights are designed using lightweight aluminium or steel frames for several good reasons: They provide great weight saving and strength, and also require little to no maintenance when compared to wooden frames. Using these types of materials does have one major disadvantage however, in that metals are extremely efficient conductors of heat, […]
Rooflights and roof windows are both popular choices for bringing natural daylight into a property, and rooflights can also provide a variety of other benefits, such as natural ventilation and access to roof terraces. When selecting a roof windows or rooflights for pitched roofs, there are several specification considerations to think about – and one […]
The benefits of specifying rooflights and roof windows are clear: they provide high levels of natural light, they can be wonderful sources of ventilation, and they contribute to the thermal comfort of a building. Roof windows and rooflights also provide an aesthetically pleasing addition to the external appearance of a property. But what else should […]
We have already demonstrated that the use of thermal breaks within aluminium extrusions can be an effective way of managing heat transfer and cold bridging. However there are occasions where the design of the framework means that including a thermal break can actually reduce performance. The simulation below shows a fixed glass rooflight bonded […]
