Benefits And Applications Of Polyisocyanurate :

Benefits And Applications Of Polyisocyanurate The Polyisocyanurate foam insulation is commonly termed as polyiso which is a variety of thermoplastic produced in the form of a foam. It is used as a rigid thermal insulation. It is widely used in numerous types of commercial based building applications like roof insulation, wall insulation, sheathing purpose and so on. With its rising popularity, it is also being used in residential buildings.

1. Expanded Polystyrene foam:

1. Expanded Polystyrene foam This variety of Polyisocyanurate Foam Insulation is the cheapest one of them all and also the least popular in the market. The r-value of this foam varies from 3.6 to 4 per inch of the total thickness. Polystyrene is used in insulated concrete forms and also in commercial buildings for roof panel insulation or walls.

Extruded Polystyrene Foam:

Extruded Polystyrene Foam The extruded polystyrene foam is known as a pink or blue board. It is available in a wide variety of thickness and edge-related profiles. The r-value of these foams is better than the expanded polystyrene foams with 4.5 to 5 per inch of thickness. If you are looking for options in Soffit Installation , these foams are lightweight, affordable and user - friendly. It is ideal for insulating the basement walls and under slab areas.

3. Polyisocyanurate foam sheet:

3. Polyisocyanurate foam sheet This version of the foam sheets is the most expensive one. These foam sheets contain closed celled sheets which have low conductivity gases held inside their cell which is either HCFC or CFC gases. The reason that these sheets reflect a high R-value is because the sheets have thermal resistance inside the gases held inside the cells. However, these sheets come with a disadvantage as well that includes gassing of CFC or HCFC gas which leads to a gradual decrease in the R-value of the sheets as the gas slowly escapes.

Applications:

Applications When looking for roof insulation, the polyiso is the only one with high thermal foam to meet the UL 1256 and FM 4450. These sheets find a wide range of applications in walls because their foil side of the insulation has the highest r value for each inch and also a high u value can be gained via minimum possible thickness. This helps bring down the overall footprint of the said buildings while bringing down the costs incurred during construction.
