ITP Supplies Award-Winning Breather Membrane For Prestigious Commercial Development

Building envelope specialists, ITP Ltd, supplied the award-winning Stamisol Safe One breather membrane for Myo New Street Square, the latest addition to one of Central London’s most prestigious commercial developments.

The first phase of the New Street Square project was developed by Landsec in 2008, transforming the area into a vibrant campus with four office buildings clustered around new public realm and retail amenities. The development was the result of a close collaboration with the City of London, The Goldsmiths, local residents and council representatives which enabled Landsec to complete the second phase in 2016 with the construction of 1 New Street Square.

Landsec’s continued investment in New Street Square will be a conversion of the 3 New Street Square building into six floors of flexible, fitted office space, meeting rooms and event spaces – all under the Myo brand. This will ensure that the estate retains a contemporary feel and attracts a high-profile occupier base. Myo customers will enjoy stunning 360-degree panoramic views across London and to St Paul’s Cathedral.

Stamisol Safe One has been specified to protect the long-term condition of the external wall system and prevent the build-up of condensation in the insulation layer. Its innovative design has been at the forefront of membrane development, representing the first breather membrane in the UK to combine a Euroclass A2 fire safety rating with W1 water tightness.

We are delighted to contribute another specification in support of Landsec, a renowned developer which owns and manages a diverse portfolio of offices, retail and leisure representing some of the most successful and recognisable property assets in the UK. We recently supplied Stamisol Safe One for Landsec’s iconic Piccadilly Lights development.  Along with its A2 and W1 credentials, Stamisol Safe One offers a range of other performance attributes which make it a go-to choice for high-profile projects like Myo New Street Square, including exceptional breathability, waterproofing of 7000mm and UV resistance of 5000 hours.
