Pitched roof insulation details.
To create a warm pitched roof insulation such as kingspan kooltherm k7 pitched roof board should be fitted between and over the rafters.
All you need to add is timber.
When it comes to pitched roofs however adding a thick layer of insulation to the rafters can result in a depth of roof construction that may not suit every site meaning over rafter insulation sarking only is not a viable option.
Pitched roofs are a common sight in the uk owing to their versatility and typical low maintenance requirements when compared to other forms of roof construction.
