About Structural Panels Inc.

Structural Panels Inc. is an all-Canadian, family owned and operated manufacturer of high-quality, steel-skinned insulated sandwich panels that are ideal for walls, partitions, ceilings, and value-added projects.

Our products have been successfully integrated into countless commercial, industrial and residential projects across the country and overseas. Available in a wide range of core thicknesses and colours, our custom-made Rockwall™ and Isowall® panels are particularly well-suited for industries requiring clean rooms, fire resistance (1, 2 & 3 hours), controlled temperature rooms and high wash-down areas. We also offer a complete range of associated and accessory materials to complement our products and support a complete installation.

Established in 1987 as ‘Isowall Inc.’, we started manufacturing an insulated panel that features an expanded polystyrene (EPS) core called Isowall®. Isowall® panels are particularly adept for architectural applications where thermal efficiency and/or a controlled atmosphere is required. Throughout the years, Isowall® panels have continued to meet established criteria set by Agricultural Canada’s Food Production and Inspection Branch (now known as CFIA), and continue to be used wherever insulating, sanitary, and/or washable walls or ceilings are required.

In 1997, we began producing Rockwall™; a panel with a superior mineral wool core that features 1, 2 & 3 hour Warnock Hersey-certified fire resistance as well as a consistently high insulation value. Developed specifically to meet the demand for a fire-resistant, aesthetic, high performance, steel-faced building or wall system, this airtight panel system can be installed easily and quickly and provides an efficient thermal envelope that features unrivaled fire resistance while leaving a small carbon footprint.

We’re a leading supplier of structural insulated panels to construction companies, architects, designers, contractors and specialty builders throughout all of Canada and beyond.

Over the years, we have established strong relationships with a number of different industries, including (but not limited to); food and beverage storage and processing, mining and oilfield, farming and agriculture, machinery, electrical, and retail establishments.

More than 30 years later, our company is growing. We are continually expanding our product lines and services to provide additional insulated and acoustical solutions for our clients. Let us know how we can help with your building project.
