Building industry has been increasingly heading towards the greatest energy savings and thus towards a construction of low-energy and passive houses. Thermal bridge issue, which is the contents of this publication, is closely related to that. A very practical guide presents to designers, engineers, building contractors and students 85 tested, counted and functional details. Construction details respect the Czech reality, Czech ways of building and usual construction materials. Individual details were selected in critical areas of enclosure walls and checked in several variants. A book Thermal Bridges - Details for Low Energy and Passive Houses is a sequel of years of work of Mr. Roman Subrt focused on this field; the book builds on previous highly successful parts.
