Types of Roofing Insulation


Types of Roof Insulation

Wood Fiber: - Among various roof insulations, the most commonly used is wood fiber. It is an organic compound composed of wood, cane or other vegetable fibers mixed with binders and fillers. The wood insulation can be impregnated with asphalt to enhance its moisture resistance.

Concrete block insulation: - It is made up of foam board and needs to be placed outside of the wall. It is ideally suited for unfinished walls, including foundation walls. It requires specialized skills. The biggest advantage of using this type of insulation is, it insulates cores and increases wall R-value.

Polyisocyanurate:- It is a closed cell foam plastic insulation, which is sandwiched between organic and inorganic felt facers, glass fiber mat facers or glass fiber re-enforced aluminum foil facers. It also features chlorine free blowing agent which expands the foam material, creating a closed cell structure that gives the insulation.

Extruded polystyrene:- Extruded polystyrene is composed of a blended polystyrene polymer heated and run through an extrusion process. The materials are then exposed to atmospheric conditions, which causes it to expand and create closed cell structure.

Gypsum board: - It is a non structural, non combustible, water resistant and treated gypsum core panel. It comes with a proprietary, non asphalt coating on one side to enhance roof membrane adhesion. This insulation is typically used as a cover board over foam plastic insulation.
