Spray foam is a chemical product made up of isocyanate and polyol resin. When isocynate and polyol resin react with each other they expand its liquid volume after it is sprayed in place.
Spray foam is consider to be the best possible type of insulation materials for homes. This type of insulation is perfect for the different areas in our home. There are many reasons for choosing this spray foam insulation.
Benefits of Spray Foam Insulation
R-value stands for the insulation capacity of a material. It refers to the amount of heat that a material can resist. When it comes to choosing the insulation material for your home so it is good to choose something with high R-value.
Spray foam fits this class. There are two types of spray foams and you must choose the right one.
Open cell foam
Close cell foam
Closed cell foam has higher density, high insulation and also offers better air as compare to open cell foam. Open cell foam is used for interior walls and closed cell foam is used for outer walls. R-value of closed cell foam is highest amongst all insulations currently available in Pakistan.
When checked with thermal imaging camera, fiber glass insulation has small gaps between the batts. Spray foam is more reliable because it does not have these gaps through which heat can pass. That’s why spray foam is considered to be a better option if you want to save energy and create a comfortable living space.
Spray Foam Insulation Does Not Consume More Space
Spray foam is extremely dense as compared to any other type of insulation material used in homes. The advantage of this high density is that it does not consume much space to deliver high level of insulation.
Any other materials will have to be installed in more thickness however spray foam can offer superior insulative property in lesser thickness.
Fill Up Inaccessible Gaps
Spray foam in Pakistan can seal all types of cracks and gaps which is not possible with other forms of materials.
Typically most homes will have lots of irregular areas and surfaces. Any other insulation types can not fill the gaps on all the surfaces.
Spray foam can enter almost all types of cavities in the roofs, walls and attics. Its space-saving property also means saving more space in the attic where there is always a dearth of usable room.
Add to existing walls because of this unique property, it can be sprayed onto existing walls without any need of finishing. There is no need to rework the drywall. It require to create tiny holes in the wall and spray the foam. It will then expand and fill up the area.
Choose closed cell spray foam and it will create dense air vapor barrier. Most owners of home do not know how damaging condensation can be to their home. This type of insulation can seal water vapor and prevent the damaging effects of condensation like as development of mould.
There are three types of spray foams based on their density. The choice of the type will depend on the type of application and the area.
High density- Choose this if you need to have your roof insulated and sealed.
Medium density- Use this type for interior walls and cavities
Low density- It is recommended not to use this type of foams
Spray foams can be used in different areas of your home including the roofs, walls and attics. If they are not properly handled then it will be difficult for you to undo the damages.
