The Common Kinds of Roof Insulation


The type of insulation that adds value to the performance of a roof is an essential part of the house. The building construction manager recommends roof insulation for many other reasons. It is the reason when professional choose a particular type of roof insulation; they saw whether the material fulfills the thermal needs of the house or not. They also consider the energy codes and then assemble the insulation on the roof.

The function of membrane and the overall structural deck play a significant role in making the insulation a complete part of the ceiling. The durability of insulation depends on successful assembly of the insulation and other areas of the upper limit. If you would choose a weak material, then you would get poor performance in the end.

The Types of Insulation:

There are many types of standard in the market with their distinctive features. Getting the appropriate knowledge and seeing the structure of the roof would help you choose the best material among all. Wood fiber, polystyrene is the commonly available materials. Perlite and polyisocyanurate are other types.  Let’s have a look at all the common types of roof insulation for making a better decision about the roof and the overall house.

Wood Fiber:

The name of the material shows us that it is the organic insulation floorboard made of wood or the fine vegetable fibers. There are fillers and binders used for composing the insulation and giving it a final shape. The kind of insulation comes with the coating of asphalt or impregnated with asphalt. The property enhances the resistance of moisture on the roof. It is essential that the engineering manager select the uncoated insulation for the roofs that are not made to match the coating of asphalt.

Perlite Insulation Roof board:

The inorganic option of insulation made of expanded form of siliceous volcanic glass. Some of the organic fibers and material binders used for giving it a final shape. There is a coating of asphalt at the top surface of the material that controls the adhesive. It also limits the absorption of the asphalt material in the roof insulation all through the application of roof-membrane.

Polyisocyanurate Insulation:

The closed cell foam composed of plastic placed between different kinds of faces. There are organic, inorganic felt faces, and aluminum foil facers used for coating the insulation. Glass-fiber mat facers used for coating. The foam material expands with the chlorine-free blowing chemical agent that further creates the closed-cell formation.  The structure helps in resisting the high thermal condition. The air diffuses in the in the cell structure of insulation and reduces the resistance of thermal. The level of insulating efficiency remains on a very high level that is not available in other kinds of insulation.

Polystyrene Insulation:

There are two methods of making the insulation. One expanded and the other extruded. Polystyrene polymer and a foaming agent are the components of expanded polystyrene. The material turns into uniform once is it exposed to the sun heat and takes the shape of closed cell insulation. The density of polystyrene is 0.70-3 pounds per cubic foot that are easily available in the market.

On the other hand, the process of heating used in another type is also prevalent in the market. Extrusion is for making extruded polystyrene polymer.  The material quickly expands in open air and turns in closed-cell structure. It is readily available on the market with a density of 1.3-2.2pcf.
