Acceptable Construction Details
These Acceptable Construction Details (ACDs) focus on thermal bridging and airtightness. This guide will help appropriate persons to achieve the performance standards in the Technical Guidance Document (TGD) to Part L of the Building Regulations 2011 – Conservation of Fuel and Energy – Dwellings.
The guide is presented in 2 sections. Section 1 discusses the general theory of insulation continuity and airtightness in construction. Section 2, in seven separate parts, provides indicative detail drawings of thermal insulation and airtightness provisions for specific construction interfaces.
