Welcome to the website for the UK's first guide on Design and Detailing for Airtightness, the second of three web mounted design guides commissioned by SEDA - the Scottish Ecological Design Association - and funded by a Sustainable Action Grant from the Scottish Executive.

The guide is divided into six chapters; Chapters One to Five examine the context and principles of designing for airtightness. Chapter six consists of five typical construction details together with alternatives which optimise the potential for each detail to exploit airtighness techniques, along with explanations and costs.

The research presented on this site was prepared by Locate Architects.
