British Museum Egyptian Gallery

The Egyptian Gallery was the first of many projects at the Museum to benefit from a replacement duo-pitch rooflight using Lonsdale’s ThermGard Roof Light System.

After having procured roof lanterns of varying quality and with disappointing results from different manufacturers, the Client was determined to establish a design that met their very high criteria for thermal performance and protection of the priceless exhibits from damaging UV light. Whilst wanting the benefits of modern aluminium systems, there was a requirement for a ‘heritage’ appearance so that any replacement roof lanterns mirrored the original timber construction. High performance solar control glass was also specified to reduce harmful UV light to the exhibits below. Solar protection was further enhanced by the fitting of external shading blinds to the overhead glazing which produce the slightly ‘eerie’ affect that can be seen in this image. Such was the success of this initial project, the Client has held Lonsdale as the benchmark by which other roof light manufacturers are measured and we repay this loyalty by ensuring a first class job every time.
