Ecological Building Systems UK Ltd are delighted to bring you a unique opportunity to join industry leaders for a Masterclass event titled Insulating & Achieving Airtightness with Cross Laminated Timber. This one-off event will be held in London on Thursday, 11th May 2017.
Retrofitting thermal insulation in buildings presents a unique opportunity to significantly reduce heat losses, improve comfort and reduce fuel bills. This new training course will provide a unique opportunity to see the latest developments in low energy retrofits. The course also covers Passivhaus and Enerphit principles and provides guidance on how to optimise specifications to offset condensation risk.
One of the most significant factors required to maximize the energy efficiency of a roof, particularly when insulation follows the pitch of a roof, is to ensure that it is sealed both airtightly internally with a suitable vapour control layer such as INTELLO PLUS and wind tightly externally with a suitable diffusion open membrane such as SOLITEX PLUS CONNECT.
Fintan Wallace (Architectural Technologist & Certified European Passivhaus designer/tradesperson) from Ecological Building Systems UK Ltd discusses
the importance of Wind Tightness in ensuring a roof build up delivers its designed thermal performance.
At the design stage, whether detailing a new build or retrofit, externally insulating a roof can be the most effective option to upgrade thermal performance. This is especially pertinent if there is a living space in the roof.
A local Architect asked the following questions regarding this subject recently:
Why Should I Consider Specifying External Insulation on a Roof?
