Spray foams are without doubt considered to be the best-possible types of insulation materials for homes. What are the reasons this type of insulation is perfect for different areas in your home, especially the attic?
1. High R-value
R-value stands for the insulation capacity of a material. In other terms, it refers to the amount of heat that a material can resist. So when it comes to choosing insulation material for your home, it is best to choose something with high R-value.

Spray foam ideally fits this class. There are but there are different types of spray foams and you must choose the right one.

– Open cell foam

– Closed cell foam

Closed cell foam has higher density, higher insulation, and offers better air/moisture barrier. This is why open-cell foam is used for interior walls and closed cell for outer walls.

In fact, closed cell foam offers the highest possible R-value amongst all the insulation materials available currently. Its R-value can be as high as r7/inch.

2. Solid barrier
When checked under thermal imaging camera, fiber glass insulation has tiny gaps between the batts. Spray foam is more reliable as it doesn’t have these gaps through which heat could escape.

Therefore, foam is considered to be a far better option if you want to save more energy and create a more comfortable living space!

3. Foam doesn’t consume much space
One of the advantages of using spray foam is that it is extremely dense compared to any other type of insulation material used in homes. The benefit of this high density is that it doesn’t consume much space to deliver high level of insulation.

While other materials will have to be installed in more thickness, spray foam can offer superior insulative property in lesser thickness.

4. Fill up all inaccessible gaps
Spay foam insulation can seal all types of cracks and gaps. This is usually not possible with other forms of materials.

Typically most homes will have lots of irregular areas and surfaces. Other insulation types cannot fill the gaps on all the surfaces.

Spray foam on the other hand, 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.

All that is required is to create tiny holes within the wall and spray the foam. It will then expand and fill up the area.

5. Preventing condensation
Choose closed-cell spray foam and it will create dense air/water vapour barrier. Most home owners don’t know how damaging condensation can be to their home. But this type of insulation can seal water vapour and prevent the damaging effects of condensation such as development of mould.

Different density of spray foams

There are 3 main types of spray foams based on their density. The choice of the type will depend on the kind of application and the area/surface.

– High density – choose high density foam if you need to have your roof and attic insulated and sealed.

– Medium density – use this type for interior walls and cavities.

– Low density – it is recommended not to use low density foams.

It is recommended to have your home insulation  by a pro. Spray foams can be used in different areas of your home including the attics, roofs, and walls. If they are not properly handled, it will be difficult for you to undo the damages.
