Mini Split Heat Pump Sizing in Cambridge – What Is Rigid Roof Insulation?

Rigid roof insulation is the term for a number of different insulators grouped together due to their predefined shape and panelized construction. Many different types of rigid roof insulation of varying materials and construction types exist. These insulators are made of materials ranging from rock to polystyrene. In most cases, these insulators come in precut panels called ‘batts,’ but it is generally very easy to recut them to fit a project of any size. In addition to roofs, rigid insulation may be found in the walls and ceilings of a building.

In general, people prefer using rigid roof insulation to other types for three reasons. They provide more insulation, based on capacity per square inch (square meter), than other forms. They resist rot, water damage and pest infestation better than other materials. Even natural rigid roof insulation has received extensive processing in order to make it a viable insulator, and this processing makes it resistant to many natural age effects. Lastly, it is typically much easier to install than soft or blown insulation.

Perlite and gypsum board are both made of rock. These materials are very strong, but will shatter or crumble under enough pressure. Both of these types of rigid roof insulation are typically implanted with glass and asphalt, although they are occasionally used in their natural form. Perlite is generally used on its own, but gypsum board is typically paired with a synthetic insulator both to improve its structure and to provide additional insulation.
