Introduction
Spray foam is a material to prevent air from entering, which is suitable for insulating piping, floors, ceilings, walls, windows, doors and other solid structures. This foam spray can be used for any type of customer's needs, and unlike normal insulation, it does not change shape and completely fills the seam and gap.
Polyurethane spray foam
Today, building insulation and preventing energy wastage is one of the topics that people are paying a lot of attention to. Polyurethane spray foam acts as an insulator and can prevent energy wastage. This insulation has high adhesive strength and is easy to apply.
Polyurethane spray spray
Spray foams are available in two categories, open cell and closed cell, which are briefly explained below.
Open cell foam spray
Open-cell polyurethane insulation is a type of spray foam whose small pores are not completely opened. There are less chemicals in this insulation, hence the lower price. Polyurethane foam insulation is used under the roof, walls between buildings, inside bathrooms and between floors. Open cell foam insulation is the most used as sound insulation.
Polyurethane cell foam
This insulation has a higher density and is denser than open cell foam. Also, this insulation has a more compact and fine cell structure. Closed cell insulation can be used outdoors to prevent water vapor penetration. Closed cell foam expands after injection and its volume increases and then hardens. This feature of closed cell foam makes it possible to use polyurethane spray foam as sound and thermal insulation in places that need sealant. Among the applications of polyurethane foam spray, we can mention the insulation of chicken farms, the insulation of mushroom growing halls, the refrigeration industry, the insulation of all kinds of sheds, etc.
How to use polyurethane spray foam
cleaning the desired surface
wetting the desired surface
double spraying the desired surface
Before using this spray, you must clean the desired surface completely and free of any contamination.
In order to increase the adhesion of the insulation, it is better to moisten it a little.
At this stage, Spray on the surface. so that it covers 50% of the work surface.
If you need more sealing, spray the second one before the first insulation dries.
