Insurers who no longer insure your old homes.

What value are you left with if you sell them and they are no longer insurable? Will they still be financeable?


A product that supports the environment

Improving energy efficiency and reducing the environmental footprint of existing buildings are core objectives of Quebec’s Energy Transition Master Plan. Supporting the development of a new market for recycled EPS polystyrene is also one of the Quebec government’s priorities when it comes to processing residual plastics.

Exceeding Recyc-Québec’s recommended targets for reducing construction, renovation and demolition (CRD) waste on worksites, Inject-Styrène Technologie asked itself why not take post-consumer EPS polystyrene, a high-performance insulator, and turn it into polystyrene-injected insulation.
