Thermax Insulator, Ltd
Thermax Insulator Ltd. was founded by Glen Last in Smithers, BC, and has spent more than three decades building a reputation for honest, high-quality insulation work across British Columbia's Pacific Northwest. Owner Glen brings over 35 years of hands-on insulation experience and holds professional certifications that set Thermax apart from general contractors dabbling in insulation.
What makes Thermax Insulators different isn't just the products we use — it's the way we do business. Every project starts with a free inspection. Every recommendation is based on what the building actually needs. And every job is completed with the level of care you'd expect from a contractor who relies entirely on word-of-mouth and referrals.
We serve communities from Haida Gwaii to Burns Lake, including Smithers, Terrace, Kitimat, Prince Rupert, Hazelton, Witset, Telkwa, Houston, Meziadin, and beyond. Whether you're a homeowner looking to cut heating costs or a contractor who needs a reliable insulation sub-trade, Thermax is the team you want on your side
Relationships
We build lasting relationships by being straight with our clients. That means honest assessments, following through on commitments, and treating every job — large or small — with the same level of care. Most of our work comes through referrals, and we don't take that trust lightly
Experience
With over 35 years in the insulation trade and certifications to back it up, Glen and the Thermax team have seen and solved virtually every insulation challenge in the Pacific Northwest. From remote Haida Gwaii job sites to busy commercial builds in Terrace, we bring proven expertise to every project.
Accountability
We stand behind our work. If something isn't right, we make it right. And because we start every project with a free inspection and clear recommendations, there are no surprises — for you or for us.
Our Mission
Keeping the Pacific Northwest Insulated, One Building at a Time
At Thermax Insulators, our mission is simple: deliver the most effective insulation solutions available, using the best products on the market, at a fair price — and do it with the honesty and professionalism that every client deserves.
We believe energy-efficient buildings are better for homeowners, better for businesses, and better for our communities. That's why we offer free inspections, provide transparent recommendations, and use premium products like BASF Walltite ECO spray foam that deliver real, measurable results.
Whether we're insulating a crawlspace in Smithers or a commercial warehouse in Terrace, we show up on time, do the job right, and leave the space cleaner than we found it. That's the Thermax promise

Glen and his team at Thermax Insulators were fantastic. They provided all the details we needed up front, and the quote provided was accurate. We would most certainly hire them again and happy to provide a reference!
