Here are 3 good reasons not to inject polystyrene microbeads (PSE) without a binding agent.

Are the walls empty?

The microbeads are tiny, between .05 and 3 mm in diameter. They are made up of 98% air and only 2% matter, therefore as light as air. A simple breath of your breath is enough to move them. These characteristics give them great fluidity and allow them to escape easily. A simple hole the size of a finger would be enough to allow the entire contents of the spaces filled in this way to escape. Back to square one! ☹ L’agent liant assure la tenue de l’isolant tout au long de son cycle de vie.☹ The binding agent ensures that the insulation holds up throughout its life cycle.

Faulty insulation?

As light as air, microbeads move under a simple current of air. Allowing the infiltrating air to pass without restraint. In addition, as the insulation moves, it loses its insulating power. On the other hand, the microbeads escape, the insulation leaks! The addition of a binding agent ensures the desired maximum density and the strength of the insulation for guaranteed thermal performance. Also significantly reducing the rate of air infiltration.

Ecological disaster?

It takes approximately 150,000,000 microbeads to form 1 cubic meter of insulation! The quantity needed to insulate an average wall area of ​​120 square feet. On the other hand, and it is well known, old houses are often filled with holes allowing air to infiltrate into the hollow spaces. These same holes also allow microbeads to escape to the outside. Using a binding agent for the microbeads injection insulation ensures an effective and safe hold in order to eliminate any risk of pollution.
