What are the Features and Benefits of Spray Foam Insulation?

PU spray foam is a non-formaldehyde-free organic material or chemicals that adversely affect the ozone layer. In doing so, it saves energy and reduces the use of fossil fuels, thereby affecting the reduction of greenhouse gas emissions. So, you may try Toronto spray foam insulation.

It also affects the high quality of indoor air (IAQ), requires less energy to generate than all other widespread types of insulation, saves energy both during transport and installation.

PU foam spray has a special advantage in energy savings in the transport-related part. Many other types of thermal insulation are transported in trucks in their finished form, and due to their low specific gravity, transport is not fully optimized, as trucks filled in volumes drive significantly less mass than possible.

On the other hand, the PU foam necessary for the thermal insulation of one house can be converted into a pickup, or a van, since the contents of one bottle are expanded several times during the installation. Therefore, when transporting PU, only transport of PU is paid, and the air becomes part of the thermal insulation only during installation.

It over time maintains its characteristics, it leaves less waste and in one product (depending on the formula and requirements of the project) can take the role of 3-4 different products: insulation, air barriers, sealants, moisture suppression and serves as a barrier to water.

PU foam in several ways affects the reduction of energy consumption:

high R value per inch (with open-cell R-3.5 / inch, with closed cells, R-6 / inch)
eliminates air penetration
helps control moisture and condensation
reduces temperature convection in the walls and in the attic
eliminates the negative effects of wind that “relates” the wind (wind)
It is efficient at low and high temperatures
provides the optimum environment in which the ventilation system can work more efficiently.

PU foam with closed cells contributes to the structural construction of the whole building and makes it more resistant to the movement of soil, wind, etc.
reduces the external noise that penetrates through numerous cracks in the building
foam with closed cells can also be used as a waterproofing layer.

The special advantage of PU spray foam in comparison to other thermal insulation systems is that no additional plate fixing system is needed, stiffening, sealing joints, etc. Additionally, all surpluses can be easily removed with scalpel and sandpaper. This particular advantage is when we want to preserve some part of the interior design due to the aesthetic impression.

Polyurethane spray foam can be pre-painted, coated with panels or plasterboard panels, embroidered with wallpaper, etc. Any possible damage can be easily corrected by simply replenishing the PU foam in a damaged place. During any interventions, you can simply cut the PU foam with a scalpel, it does not bother and does not collect dust inside its interior, and it will not make much clutter even if the intervention is 20 years after installation.
