Over 10,000m² of 10mm Clear Twinwall Marlon ST was used in the refurbishment of the roof of the iconic Paddington Station in London.
Requirements
- Light weight
- Easy installation
- Suitable for cold curving
- Meet fire and safety regulations
The railway station, which sees more than 60 million passengers pass through every year, had become dark with substantial loss of light through the old roof glazing. The glazing sheet, installed 23 years previously, was estimated to have a light transmission of just 18% due to external weathering and discolouring to the underside caused by a build-up of diesel exhaust contamination.
The contractors, Morgan Sindall, consulted with TBS Polycarbonates and the solution was to use Brett Martin’s Clear Twinwall Marlon ST polycarbonate sheet. 10mm Twinwall Marlon ST not only met all of the safety and fire regulations but is light in weight and suitable for cold curving on site making for easy installation of the sheets.
As the work had to be carried out with minimal disruption to the running of the station, Brett Martin worked with TBS Polycarbonates and the contractors to deliver the Marlon ST sheets cut to size and pre-taped, ready for installation. The order was then packed into four shipments and delivered to TBS Polycarbonates on an agreed schedule so that the sheets could be delivered as required to site at night time.
The results speak for themselves. With 79% of light transmission, the newly installed Marlon ST sheets have created an impressive curved rooflight which floods the station with natural daylight creating a bright environment for passengers whilst protecting them from the elements.
