New guidance on inverted warm roofs is contained in European Technical Approval Guidance 031 (ETAG 031) which has been issued in order to ensure consistent standards of assessment of inverted roof systems throughout Europe.


JPA TL Software for Construction –

In 1985 JPA began developing a suite of specialist software for the construction industry to calculate the thermal performance of the building envelope and the likelihood of condensation. That software is now regarded as industry standard and is widely used throughout the UK and Europe and as far afield as China and the United States. We provide straightforward, effective software, specialising in thermal calculation tools which enable designers to improve the energy performance of their buildings and to demonstrate compliance with the increasingly complex requirements of Building Regulations.
