Build For The Future By:

Building Faster

By combining exterior insulation with structural sheathing, builders can install multiple layers at once while reducing labour costs and labour hours.

Building Better

Create a more comfortable, energy efficient home by wrapping the building in a blanket of continuous exterior insulation that eliminates thermal bridging and moves the dew point to the outside.

Building Smarter

Our solutions don’t require builders to change how they build – your preferred processes, techniques and methods remain the same and nothing changes for inspections, repairs, and renovations. SIS Panels are installed the same as regular Plywood.

Insulation Options & Details – Coming Soon

Wildfires in Canada were ten times worse than what has been seen in the past, 11 million hectares have been burned so far in 2023. This is a stark reminder of the urgent need for proactive measures to protect our environment and communities.

Benefits of One-Sided MgO SIS Panels

Custom Made For Your Project

We can tailor our MgO SIS Panels to meet specific requirements and optimize performance. For areas/projects that require fire-rated assemblies, consider substituting the EPS insulation for Mineral Wool.

Choose thicker interior and exterior MgO boards for greater structural strength or thicker insulation for a higher R-Value.

Effortlessly Reduce Thermal Bridging

Maximize energy efficiency by addressing the issue of thermal bridging. Traditional exterior walls suffer from significant heat loss, with around 14-20% of exterior walls losing heat through areas without proper insulation.
By integrating insulated sheathing into your assembly, you can enhance the entire system. A better building envelope increases your mechanical system’s lifespan by reducing how long & often it needs to work.

Streamlined Installation

We believe in utilizing materials you already know and trust to make your construction experience seamless. Framers can effortlessly install these panels just like regular Plywood or OSB without any special tools or training.

By replacing the sheathing you were going to use with this SIS Panel, you can leverage the benefits of insulated sheathing without complicating your construction workflow.

Supports Cladding Systems

Our premium 1/2″ MgO offers exceptional structural strength, enabling you to directly install heavy cladding materials like James Hardie board or brick onto the MgO SIS Panel – no need to install to the stud.

This provides you a generous and convenient nailing surface, simplifying the cladding process and saving you time and effort.

How It’s Made

Our climate-controlled factory ensures the highest quality control over our lamination process to ensure it meets the strictest building standards. Our precision-built SIS Panels adhere to local codes and standards, undergoing meticulous inspections at every stage of manufacturing.

Want to use a thinner or thicker MgO Board? Need an insulation option with a higher R-Value? Are you building in an area with zero-clearance lot lines?

Our manufacturing process makes it easy to mix & match different products & benefits – giving builders the ability to meet more project requirements with a single solution.
