Mineral wool insulation is typically used on projects where there are non-combustibility requirements by code. Used in EIFS (Exterior Insulation Finish Systems) in lieu of EPS (Expanded Polystyrene) for the fire-rating, it is more difficult to work with because of it’s spongey nature, and tends to require additional materials as well as time.
The most common supplier of mineral wool insulation on the Toronto market is a company by the name of Roxul. With a manufacturing plant in Milton – just off the 401, they are the preferred supplier for most of our projects. Due to the manufacturing process, individual fibres in the board are extremely tiny and may be considered a possible carcinogen to humans when exposed to over a long period of time (similar to asbestos) if they become trapped in the lungs. Once embedded into the wall with a base coat on one side and a weather barrier on the other, concerns about this are negligible. Care should be taken when removing or handling mineral insulation, and eyewear, gloves and a respirator are recommended.
We are able to accomodate toronto insulation projects where mineral insulation may be required due to non-combustibility requirements by code, whether it’s because of the proximity to another building or other reasons.
