When did we open our manufacturing facility and head office?

Founded as a family business, ROCKWOOL has a history of responsible environmental practices, developing community partnerships, and investing in the communities in which we operate globally. Our first production facility in North America – located in Milton, Ontario is an example of just that.

Having opened in September of 1988 and now in operation for more than 30 years, we are a proud neighbour and continue to partner with the community by investing in sustainable operations and getting actively involved in local programs and causes that support the wellbeing and prosperity of local residents.

The 750,000-square-foot manufacturing plant is located on Steeles Avenue. The facility was purchased as a brownfield site from Lafarge Canada, brownfield meaning that the land was previously used for industrial purposes.

In 2008 we then undertook a $175M renovation and expansion of the Milton site increasing production capacity and creating 100 additional local jobs, before finalizing construction of our corporate headquarters for the region in December of 2014 located on Esquesing Line.

For a detailed look at what it means to have ROCKWOOL in your community, we created a Community Brochure. It covers everything from how our manufacturing facilities operate to working at ROCKWOOL and our social responsibility efforts to support local programs and causes.

ROCKWOOL is a positive and contributing member of the Milton community and surrounding areas. Certainly, in our case with the Halton Learning Foundation, ROCKWOOL’s support of individual students in need has been tremendous.

How does our factory operate?

Our manufacturing facilities are an example of advanced and sustainable operations. In Milton, the expansion project prioritized energy-efficiency to ensure that we leave the smallest footprint possible.

According to the Government of Ontario, this project enables ROCKWOOL (then ROXUL Inc.) to recover the energy used to manufacture our stone wool products within three weeks. We continue to look for opportunities to reduce energy consumption and have done so through investments in new technologies such as lighting retrofits, conducting regular internal audits to identify areas for improvement, and participation in Milton’s Hydro Voluntary Transitional Demand Response Program to scale back energy usage during peak times.

The Milton manufacturing facility produces our insulation products for residential, commercial, and roofing applications, as well as our full line of Grodan horticultural solutions. Producing our products in the most environmentally-responsible manner is a commitment we take very seriously at ROCKWOOL. In fact, as a company, we are holding ourselves accountable against commitments to several of the United Nations Sustainable Development Goals. The Milton facility is working diligently to reduce CO2 emissions, improve water and energy efficiencies, and minimize waste to landfill.

How’s our progress? Well today we can say that our Milton plant operates with zero production waste to landfill, uses heat recovery systems that capture heat from the production process to heat the building, has on-site recycling to transform production waste into usable raw materials, and just as is the case with all our facilities worldwide, our production process is designed for zero wastewater discharge to the environment.

A modern operation that utilizes state-of-the-art equipment and people working together to ensure the highest standards of employee safety and product quality, that’s manufacturing at ROCKWOOL Milton, Ontario. The process of manufacturing stone wool is something our organization has continued to refine over the course of our history and the below video gives you an up-close and personal experience of today’s operations.
