 ====== Insulating an attic staircase ======
+In their old, original form, attic staircases which often lead to the loft or roof space in single-family houses cause extremely high heat losses. Usually the door of the hatch is only a few millimetres thick and the construction is often extremely non-airtight in addition, due to which warm air flows out through the edge joint and cold air enters in the winter, usually from leaks located on the ground floor((  One of the reasons for cold air currents at floor level on the ground floor )) . Rigid insulation panels made of various materials can be used for insulating this, the main factor here is how easy it is to cut and handle the panels. Even high performance insulation materials such as phenolic rigid foam panels (thermal conductivity 0.022 W/(mK)) are appropriate here because space for insulation material is usually limited.
