Check out our case study

See a 2018 case study based on energy efficiency analysis reports, before and after work, conducted by an expert firm commissioned by Transition Énergétique Québec.

You can also view the analysis reports before and after the injection insulation work. We carried out the work in an inhabited dwelling in a total of 8 hours. This time includes the start of work up to collection and clean-up after isolation.

Injection options

Ecobill MD/® insulation is produced by injecting agglomerated polystyrene microbeads to fill air gaps of 1 inch (2.5 cm) minimum and 16 inches (40 cm) maximum. In addition to its high thermal value, Injected Microbead Insulation provides excellent control over air movement.

Sequence of work

The Inject-Styrene process stands out for its simplicity, originality and technical features, its energy efficiency comparable to the best insulating materials on the market, and its superior ecological and environmental performance.

Discover the sequence of works for the injection of recycled microbeads.

bead injection preparation

Preparing for injection

25 mm diameter holes are drilled in your wall or partition to inject the polystyrene insulation.

bead injection preparation

Insulation injection

Recycled polystyrene microbeads are injected into the wall or partition, insulating it without demolition.

wall closure injection work

Closing after injection

Wood or plaster, the wall can be resealed immediately after injection. This makes it possible to achieve complete, effective insulation in a short space of time, without having to demolish the walls.

An ecological and economical solution.

Finalizing the work

Older buildings generally lack an effective vapour barrier to combat moisture migration inside the walls.

This moisture migration, which is bound to cause a great deal of damage over time, can be stopped by applying a vapour-barrier paint. A simple and highly effective method, when applied as recommended. Ask your professional for more information.
