INTRODUCTION
The details in this section relate to partitions and separating or party walls. The introduction document "Limiting Thermal Bridging and Air Infiltration Acceptable Construction Details" provides practical information with regards to implementation of these details onsite. This guide should be read in conjunction with these details. They are applicable to all types of external wall construction.
The details are indicative. They focus on the issues of thermal performance and air tightness. Other issues are not considered. Insulation thicknesses for the main building elements have not been provided, as these depend on the thermal properties of the materials chosen, as well as on the desired Uvalue.
Masonry materials shown on the drawings are blocks and other masonry materials, including precast and insitu concrete, may be substituted without loss of thermal performance or increased technical risk. The use of thermally resistant materials, beyond that depicted, will naturally increase the thermal performance of the building fabric.
All materials and workmanship are to be installed to Technical Guidance Document D 'Materials and Workmanship'.
These diagrams illustrate good practice for design and construction of interfaces only in respect to ensuring thermal performance and air barrier continuity. The guidance must be implemented with due regard to all other requirements imposed by the Building Regulations.
Technical Guidance Document B and Supplementary Guidance to TGD B provide guidance in relation to the provision of cavity barriers, fire stopping within combustible insulation layers and fire protection of structural elements.
