Crafts & Construction
Beam position
Wooden structure in the floor or roof area of a building.
Between-rafter insulation
Insulation method where the insulating material is placed between the roof rafters. Suitable when the roof itself remains unchanged and the attic is inhabited. Since rafter height limits the insulation thickness, an additional under-rafter layer is often added to reach the required U-value.
Brick
Traditional building material made of fired clay – mostly for roofs or walls.
Flat roof
Roof shape with low slope – special requirements for waterproofing.
Insulation
Material to reduce heat loss – e.g. mineral wool, polystyrene.
Mold
Fungal growth due to moisture – can be harmful to health and the building.
OSB board
Chipboard with a high degree of stability – often used in drywall construction.
Over-rafter insulation
Insulation that is installed above the roof beams.
Rigips
Plasterboard for drywall and ceiling cladding.
Screed
Leveling layer on the subfloor – basis for floor coverings.
Top floor ceiling insulation
Insulation method where insulation boards are laid on top of the uppermost floor ceiling, either walkable or non-walkable. The cheapest and simplest of the three roof insulation methods, suitable when the attic is unheated and uninhabited (cold roof). Achieves U-values of ≤ 0.24 W/(m²K).
Vapor barrier
Component layer that controls moisture penetration in components.
