Good for the planet

Towards carbon ‘zero’ construction.
Sustainability is a key issue for everyone involved in the construction industry. In the UK, buildings are responsible for producing around half the nation’s total CO2 emissions. It’s for this reason the government has set strict targets across the sector with the aim of reducing its carbon footprint and encouraging more efficient, sustainable practices. The result of this is that by 2018, all new build homes and commercial properties will be carbon neutral. As a manufacturer of PVC-U building components, Sureseal are here to answer the needs of the industry with our range of high performance, energy efficient products.
