Can I spray foam insulation myself?

Health is one of the main concerns of human beings. The insulation of a building is essential to ensure the safety of indoor air. However, the insulating materials that are part of the envelope are not completely waterproof, but may have perforations or discontinuities. For this reason, you should always hire a professional with the adequate tools and materials.

Emission of hazardous substances into the indoor air. The indoor air quality depends on the interaction of various factors such as relative humidity, temperature, ventilation, the activity that is carried out inside … Within these factors, emissions from construction materials represent an insignificant percentage of the total. However, it is mandatory to know that the construction materials used do not pose any risk to the user.

In the case of polyurethane, we are talking about a material with imperceptible levels of VOC, SVOC and MDI emissions, preventing the proliferation of fungi and molds, and letting the enclosure perspire without causing condensation. In fact, the projected polyurethane emissions are much lower than those of many of the insulating materials, including expert attic insulation installation.

If you are wondering what polyurethane foam has come to the right place. You may not know it, but it is a material that is found in a wide variety of products and industrial applications that we sometimes see.

How to seal attic insulation installation

It is uncommon to create an air barrier with just one material since several must generally be installed to control the flow of air between the conditioned spaces and the unconditioned exteriors.

In a wall system, there are several materials with a barrier or air brake functions. Inside out are:

the interior usually contains special materials, which can be used to control the airflow

in cold climates a vapor barrier may be required:

• insulation
• outer sheet
• weather resistant barrier
• coating

An area of ​​air leakage that is usually overlooked in the perspective of the hermetic barrier is the walls or walls between the attic and the rest of the home. The walls must be treated as an exterior wall and to achieve encapsulation on all six sides, laminate or airtight material must be installed on the side of the wall facing the attic.

Surely you hear the phrase that “hot air rises.” So the one you feel around you is rather “fresh”. The truth is that the hot air rises and in our house goes to the ceiling, so, should you thermally insulate it? Well, it all depends, there are certain variables to know.
