Especially in residential buildings, timber frame roofs are the most common construction type, while steel roof construction is found in larger or industrial buildings.
In new residential buildings, the space between rafters is filled with soft fibrous thermal insulation and finished with an exterior layer of hard thermal insulation panels. To avoid roofing removal in renovation, hard thermal insulation is often placed in the interior space due to easier execution.
