This guide assesses the thermal performance that can be expected for given levels of insulation and common construction options.
All text and graphs have been reviewed and updated to take account of the current levels of achievable insulation for walls, roofs and floors.
The guide retains the easy-to-read graphs and tables to determine the as-built construction R-values for given levels of insulation and common construction options.
This 5th edition includes new information and modelling for:
• windows and recessed light fittings
• steel-framed walls with different cladding types
• suspended concrete floors, concrete slab-on-ground floors, basement walls and waffle pods.
