What We Do
Lonsdale provides you with concise and reliable information to help designing and specifying glass roofs that bit easier. Follow our guidance and you can be sure your projects will feature safe and weather-tight roof glazing that will give many years good service.
Please take a look at the Design & Regulations pages on the website which are likely to answer any queries you may have. However, if you can’t find what you need, please contact our Technical Department where our experienced and helpful team can offer you further advice.
NBS H10 is the National Building Specification classification for patent glazing and L10 is more applicable to modular rooflights. You will find our NBS Plus Specifications cover most of the typical instances and glass types for canopies, covered ways, smoking shelters, platform glazing, atria, hipped, gable ended, pyramid, octagonal, shaped or mono pitch rooflights, skylights or lanterns. Don’t miss using this useful tool as it will speed up the specification process for you considerably.
As members of NARM, we can also provide an online CPD Seminar on the use of rooflights to provide daylighting in buildings. We promise not to bore you, but really show you how the natural daylight provided by roof lights can enhance the design and environment of your building. Contact us for details.
Finally, see our library of CAD Details illustrating section profiles and hundreds of typical installation details.
