    This material is useful where space is tight or cramped, such as cathedral ceiling. Protect foundation and damp-proofing during backfilling; It is lightweight and strong, although EPS can be crumbly. It adds to the walls' structural strength. It provides acoustic insulation in addition to thermal. Most forms of rigid board can be cut with ...

    Now, insulation is divided into two main categories: bulk insulation and reflective insulation. Buildings typically use a combination. Insulation is an important economic and environmental investment for buildings. By installing insulation, buildings use less energy for heating and cooling and occupants experience less thermal variability.

    Warm air rises, so ceiling insulation is designed to have a higher r-value and the insulation is often installed between the ceiling joists or rafters. A properly insulated and ventilated roof is called a cold roof. A warm roof is a roof that is not ventilated, [9] where the insulation is placed in line with the roof pitch. [10]
