Enerpan Structural Isulated Panels

Airtight Insulation

With steel sheathing encasing a solid polyurethane insulation core, our structural insulated panels are significantly more airtight than traditional framed structures. Even when a wall requires electrical and plumbing punctures, the closed cell insulation remains intact, minimizing air and moisture leaks.

Energy Efficient

A building system’s thermal performance is the highest concern of consumers today. At 6.7 R-value per inch, our SIPs are much more energy-efficient than traditional framed structures. This aligns your construction practices with today’s sustainable building standards.

Flame Resistant

The steel sheathing on our SIPs prevents and stops the spread of flames. We can also inject a fire-resistant resin into our polyurethane insulation, helping you meet National Fire Code of Canada standards for residential, commercial and industrial construction.

Cost Effective

With their extreme insulating properties, our SIPs reduce the need for additional building products, such as structural framing, vapour barriers, gypsum and sheeting. Our panels also require less construction time, as the system fits together simply and quickly compared to conventional framing. These lowered material and labour costs add up to higher savings.

Easy to Install

Our SIPs have simple lap joint connections, making them more efficient to install than a stud wall. You can cut our panels with inexpensive saws, attach them together or affix them to framing with standard hardware. A saw cut is all that’s required to install windows and doors.


Available in a variety of sizes, colours and thicknesses, we can manufacture our SIPs specifically to your building needs. From residential and commercial buildings, to light industrial and agricultural structures, we can build our panels into wall, roof or floor components.

Long Lifespan

Moisture, mold, bacteria: our SIPs withstand it all. Unlike traditional wood framing, or even wood SIPs, our steel panels won’t shrink or bend with time. The result: minimal air leakage and long-lasting, even finishing.

Durable Design

Structurally superior, our panels can withstand axial loads much heavier than conventional framed walls. Our designs evenly distribute weight across the entire panel—unlike traditional studs, which are spaced on specific stress points.

Traditional Building Methods

Ineffective Sealing

Conventional framing is much harder to seal. Fiberglass batts and cellulose are only marginally good insulators, and their performance depends on the quality of the installation. Air infiltration is common, leading to condensation and moisture problems.

Low Insulation Values

With conventional framing methods, wall thickness determines insulation values. Adding spray foam helps to seal corners and boost R-value, but this doesn’t guarantee an airtight envelope. Studs may also create thermal bridging and heat loss.


Conventional wood framing is much likelier to catch fire than our steel SIPs.


Conventional framing involves measuring, cutting, fitting and nailing each piece of wood and batt insulation. It may also require sheeting, which requires a vapour barrier, sanding, mudding and drywall taping. Not only is this method time consuming, but mistakes and material waste are also common. This increases labour and material costs.

Requires Expert Installers

Although conventional framing is a century-old form of construction, it still requires an experienced contractor who has the right tools for proper construction.

Costly to Customize

Traditional framing is difficult to customize at the manufacturing stage. To add an exterior facade, contractors must instead install sheeting, siding panels or brick at the construction stage—all of which cost extra money. The more durability your structure requires, the higher your costs will be.

Shorter Lifespan

Time is the enemy of traditional wood framing. Even a properly sealed traditional wall will bend and shift with time, resulting in air leakage and moisture infiltration. This can lead to infestation and rot, which cause a wall to degrade faster.

Weaker Construction

Traditional framing can be built to strength requirements, but wood will still degrade over time. It warps and twists as moisture levels vary, creating an uneven load bearing as the years pass.
