Insul-Twin is at the forefront of Exterior Cladding Technology and Building Practices. Our relationship with all of the Lower Mainland's Envelope Engineers has forged a dedicated team that specializes to keep the elements out of your wall system.

With more than 30 years experience, we have watched the industry evolve and truly understand the fundamentals.

The real work is in the details, everything that most people don't see is what ensures water is shed away. Our overall focus is to create a finish that will last the life of the structure and without the details to back the cladding this won't happen.

At Insul-Twin we strive to satisfy our customers and work with you to choose the best option of price and quality.


Our entrance and sliding patio doors have style and elegance with exceptional sound-proofing, thermal efficiency and security.

Whether it's standing up to the toughest weather or providing amazing energy performance you will enjoy peace of mind with a superior locking system–knowing your doors will stay closed.


When Insul-Twin opened its doors 35 years ago we started by insulating our own attic. Our Goal was to save money on heating costs. Our success was shown immediately in our heating bills.

Since then Insul-Twin has grown and expanded and now can insulate anything from a small renovation to entire apartment buildings. At our core, our main goal is to save you money.

We offer a complete range of traditional and the latest state-of-the art insulation materials to provide a "One stop shop" for all your insulation needs. We take great pride in our work, aiming to exceed expectations and leave our customers satisfied.
