Is Polyurethane Foam Safe To Use?
Polyurethane (PU) foam is an industry-standard when it comes to expanding foam due to its high-temperature resistance and low density. It is also flame-retardant. This allows polyurethane to be used in fire protection applications such as structural insulation, thermal insulation, flexible foams, and gaskets.
Types of Polyurethane foam
Open-cell polyurethane foam
Open-cell foam consists of millions of holes that allow air to pass through easily. This type of foam is typically used for insulation because it does not trap heat as closed-cell foams do. It also resists mould growth better than closed-cell foams do because there are more ventilation holes available for moisture to escape through.
Closed-cell polyurethane foam
Closed-cell polyurethane foam comprises millions of tiny closed cells that trap air inside them instead of allowing it to pass through freely as open-cell foams do. Closed-cell polyurethane foams are used for insulation because they provide excellent thermal resistance along with sound absorption qualities due to their porous nature.
Why is it a popular product?
The main reason why PU foam is the premier choice for fire-stopping is because it expands when exposed to heat and creates an air barrier that keeps flames from spreading in a building structure. Although this makes it a very effective way to stop the spread of fire through a building or structure, it should be noted that not all PU foam products are fire rated.
The main benefit of polyurethane foam is its R-value. This measures how well insulation works at keeping the heat in or out of your home. PU foam has an R-value between 3 and 6 per inch, depending on how thickly it is applied.
PU foam won’t release harmful gases when you use it for insulation or other purposes. It’s also easy to install and can be applied over many surfaces without damaging them.
As an effective insulator, the foam is resilient enough to protect against wind or water damage without crumbling apart like some types of insulation do over time when exposed to extremely bad weather conditions.
You can also use polyurethane foam to seal cracks in walls and other areas where water may come in contact with wood or drywall surfaces. This will help keep moisture out of your home’s structure and prevent mould growth as well as other problems related to water.
PU foam is installed in small crevices, cracks, and gaps which help with air sealings.
Lightweight and affordable, it can also be utilised as an acoustic barrier for places where soundproofing is essential but don’t want to run out of space due to bulky insulation materials.
Is it safe to use?
Yes, if it’s properly installed by professionals who have experience working with this type of material. However, certain types of fire-resistant polyurethane foam may not be appropriate for certain applications.
For example, if you’re installing it on an exterior wall it could become brittle when exposed to extreme temperatures over long periods or if moisture gets inside the wall cavity where installed.
