Sundolitt XPS – Waterproof, Load-Bearing ECO Insulation for Prestigious New Edinburgh Development Roof

Easy roof installation of Sundolitt XPS at Edinburgh Development

Sundolitt XPS 300 (extruded polystyrene) forms the core of a waterproof, load-bearing, high insulation roof system at South St Andrew Square - a prestigious £75 million, 190,000 sq ft mixed office, retail and residential scheme in the heart of Edinburgh’s historic ‘New Town’ area.

Following the demolition of the former B-listed building on the site, the new development – expected to be completed by the end of this year – features a bold collaborative design from CDA and Gareth Hoskins Architects which won the backing of the City of Edinburgh planners for its “high-quality contemporary architectural expression”.

Bryan Mawer, sales manager for Sundolitt XPS, explains that the cost-effective material is designed for inverted roofing applications alongside its established use in flooring where its load-bearing and high thermal performance are critical: “We are proud to play a part in this exceptional architectural statement in a prestigious location in Edinburgh. XPS ticks all the boxes for this kind of roofing installation – it’s a lightweight product , yet provides a high strength solution which is very easily transported to site where it can be used as a site-ready, weather resistant insulant”.

South St Andrew Square is a joint venture between Standard Life Investments Pooled Pension Property Fund and partner Peveril Securities. The main contractor is Bowmer and Kirkland.

The retail opportunities in the development have already attracted three restaurant chains to open their first branches in the UK outside London, including a New York contemporary steak house, a barbecue lobster shack and a Bombay-style café. This led Councillor Frank Ross, the city’s economy leader, to say “St Andrew Square looks set to become one of the top leisure destinations in the capital.”

Sundolitt XPS is manufactured in a wide range of thicknesses and sheet sizes, the primary range having a thermal conductivity of 0.033 – 0.037 W/mK (EN 13164). According to the type of use, it achieves outstanding compression resistance from 200 – 700 kPa (EN826) and offers exceptionally low moisture absorption through its closed-pore system - making it an ideal thermal insulator for a wide range of commercial and domestic construction applications.

It is available ex stock from Sundolitt in the UK in square or shiplap edge. Sundolitt’s UK expert team can help and advise architects, specifiers and contractors on the most appropriate XPS specification for their needs. Specifiers can call the Sundolitt UK Head Office on 01786 471 586.
