There is a growing understanding that spray foam is an unreliable, toxic, and expensive approach to insulation. As efficiency becomes more of a focal point in the building equation there is an onus to build airtight structures. While that means heating and air conditioning costs can be minimized, airtight building envelopes create inherent challenges that need to be re-assessed.

Foam insulation has long been viewed as a belt and suspender to enhance building tactics in the quest for air tightness. As known failure rates of foam systems rise, so too does optionality for alternatives. Today, we can make a better choice – a smarter choice.

Our customized ‘Smart Wall’ system is made of non-toxic materials structured to create a long-lasting building enclosure that delivers comfort, health, and efficiency without rot, mold, or other maintenance and health issues. Comprised of efficient, resilient and sustainable products, the ‘Smart Wall’ includes Havelock Wool insulation, Pro Clima membranes with Mento 1000 and Intello Plus, and Gutex exterior insulation board.

Inevitably moisture will find its way into wall cavities and it is what happens next that is paramount to building intelligently. The ‘Smart Wall’ is an airtight, low-energy, biophilic approach to wall system design & construction. It allows for the efficiency of air tightness without disrupting inherent vapor drive thanks to the high integrity of sheep’s wool's intrinsic characteristics and the industry leading technology behind Pro Clima membranes. By placing Pro Clima membranes on either side of the wall cavity, the Mento (exterior), provides an air-tight vapor open to the outside (up to 36 perms); while the Intello Plus provides the air tight vapor barrier to the inside (0.17-13.2 perms).

As a reinforced membrane, Intello Plus replaces standard blow-in insulation netting and offers exponentially more integrity to the wall. Depending on the moisture levels, its perm rate will vary while remaining airtight. Made of wood, Gutex fiberboards also allow diffusion as they regulate the interior relative humidity by virtue of their ability to absorb and release up to 15 % of their weight in moisture – without the loss of insulation capacity. 

For superior insulation in the cavity, Havelock Wool insulation actively manages moisture while not being adversely affected. Wool fibers inherently absorb and desorb moisture against 65% relative humidity.

Current code-minimum construction: Inefficient, made of foam, fiberglass, chemicals & VOCs

Current building materials are designed to maximize profit not comfort and safety

• Developed by petroleum and chemical industries
• Made to tear down in 30 years
• Safe when covered by drywall
• Inefficiencies corrected by cranking the heat and AC
• Works against nature in an attempt to battle encroaching mold growth
• Manufactured to maximize profit


 A smart wall is one that’s safe at every stage before and after construction. 

• Efficiency, resiliency, sustainability,  safety, and comfort built into the very fabric of the building
• Serious building science to address the global climate crisis
• Will last for generations
• You don’t need safety gear to protect you from these building materials
• Works with nature to handle water and moisture, eliminating the risk of mold and rot
• Natural and high performance

Why do we compromise when building the most important part of any structure: the envelope? The smart wall or smart enclosure system addresses a weakness in current practice to achieve air tightness. Along with 475 High Performance Building Supply we are proud to have created a solution to this problem.
