Insulation Requirements

Ritchie's Insulation delivers insulation products based on our clients’ requirements, whether it’s a new building, a renovation project of an existing building, or even insulating from the exterior of an existing building without affecting the interior finishes.


The different systems that we apply in completing our insulation are:

  • Beno-Mat System: a mesh is installed over the open walls and then cellulose insulation is blown in through a hole in the mesh creating a dense pack.
  • Hybrid System: a slim coat of polyurethane foam insulation is sprayed in the open walls and then the Beno-Mat System is applied to finish insulating the walls.
  • Drill and Fill System: holes are drilled from the outside of the existing home and cellulose insulation material is blown in densely.

New Building

Ritchie's Insulation can provide a quote right from the plan stage, with the ability to provide options in how to best insulate the new building. We can use the Hybrid System, the Beno-Mat System, or Polyurethane Foam to insulate the building.

Existing Building

We can meet any renovation project needs for an existing building, whether the build has been renovated right down to the framing or the building just needs insulation due to heating or cooling requirements. If renovation has taken the building to the framing, we would insulate similar to a new build with all of the options that a new build provides. If the insulation requirements are due to wanting to improve your home’s heating and cooling needs, one of our specialties is insulating the home from the exterior using our Drill and Fill System. We are one of a few insulation companies that can provide this insulation methodology, not affecting the interior finishes of your home or building.
