Poor insulation against cold and air can be the source of a lot of damage and loss in your home. Indeed, in the face of the cold, the pipes are damaged. Air infiltration is responsible for significant losses of heating energy. To avoid all this, one of the most adopted solutions is expansive foam. Is this solution effective? Find out everything there is to know about polyurethane foam here.
Expansive foam: what is it?
Natural expansive foam is a product used for caulking cracks or air intakes in a home. It is useful for clogging and insulating holes precisely. Its chemical equivalent is called polyurethane and plays the same role.
Both of these materials are used in old homes during renovations and in new constructions. They are applied to walls, an inner crack or an outer crack of a concrete foundation.
All surfaces including the floor and roof of a house can receive foam insulation. As its name suggests, it provides excellent thermal and sound insulation.
Expansive foam is sold in the form of small bombs. Individuals can use it to perform small jobs. There are also more important capacities (bombs) for the use of professionals. At Groupe Fissure Expert, we use them for major concrete hole repair work.
Why use expansive foam?
The use of foam insulation has many advantages.
Powerful thermal insulation
This material makes it possible to fill cracks, regardless of their size. If you perceive the slightest fault anywhere in the structure of your home, you can plug it using expansive foam.
In this way, heat loss will be completely eliminated. Foam insulation is made mainly of microbubbles. The latter constitute a barrier against cold (winter) and heat (summer).
Unlike its chemical equivalent (polyurethane foam), expansive foam is an odorless product. It is not toxic at all and therefore does not pose a health hazard to humans or animals. Best of all, this concrete crack repair material is completely environmentally friendly.
Easy to inject
There are no gaps that expansive foam cannot fill. Very easy to inject, this material penetrates into the slightest foundation crack to restore the structural continuity of the concrete. One of its very advantageous features is its composition. Indeed, being made mainly of air, expansive foam is very light. This allows it to easily adapt to any structure.
Strong and durable
There is no point in plugging cracks and finding them still present in the foundation after a few weeks. That’s why Groupe Fissure Expert uses foam insulation to treat Montreal saltpeter.
Indeed, this material is extremely strong. Once it is applied to a support, it remains there for a very long time. No matter how much time it spends on the stand, insulating foam does not compact.
Expansive foam is extremely soft when applied. Once applied, it hardens to the point of withstanding a pressure of 20 tons/m2.
The different insulating foams (or polyurethane foam)
You will find on the market, a wide variety of expansive foams. There are also several brands. Each differs from the other because of its peculiarities. However, the latter determine the results achieved or expected. Thus, there is the:
- Glue foam: dries quickly and allows to join materials;
- Multiposition foam: ideal for narrow places;
- Fire foam: with a 4-hour resistance capacity against fire, it is ideal for hazardous areas.
For each saltpeter or concrete joint treatment in Montreal as in all of Quebec, Groupe Fissure Expert always advises you the ideal type of foam to project.
Trust clogging professionals
In the trade you will find expansive foam bomb for small jobs at home. However, in the face of significant gaps, your action will not be sufficient for the repair of concrete slabs. Indeed, it requires more professionalism and foam of fairly high quality.
That’s why Groupe Fissure Expert offers its clogging and thermal/sound insulation services throughout Quebec and particularly in Montreal.
