Spray foam insulation has emerged as a leading solution in this transition due to its energy efficiency, durability, and performance when compared to traditional insulation materials.

Aside from the structural challenges, the thermal challenges for basements include the following functions: (1) facilitating moisture drainage at the face of the exterior insulation down to the foundation drainage system, (2) keeping temperature extremes outside the basement wall, especially cold temperatures, and (3) preventing condensation of the basement air onto the interior of walls in the basement.

It is important to take all environmental factors and design choices into consideration before choosing a particular type of flooring as resinous flooring is not a one size fits all product. For example, some resinous flooring finishes are inherently slip resistant while others need to be customized by the end user for slip resistance.

Mould growth in buildings can occur when mould spores, which are always present in buildings, are exposed to wet or humid conditions for a sufficient length of time and on an appropriate surface to support growth. Water sources can include plumbing leaks, spills, foundation seepage, roof or wall leaks, condensation on cool surfaces such as inside ductwork and on windowsills, etc. In the presence of wet or highly humid conditions, mould spores can germinate within 48 to 72 hours (about 3 days).

When it comes to flooring specification, understanding moisture measurement and floor prep will protect against pitfalls in construction.

Wood is an exceptionally versatile and attractive building material that has been used in construction for thousands of years. Wood’s advantages in construction are many. It is extremely strong in relation to its weight, is widely available, and is economically competitive with other types of building materials. Additionally, wood is durable, reusable, and carries the lowest carbon footprint of any comparable building material.

Looking at the façade industry today and for the future, there is a progression toward lightweight/low-mass solutions. This is in response to the demand for lowering the amount of embodied energy in the construction industry in an effort to address environmental impact of buildings. Lowering the weight suspended from the building superstructure will also save costs.

The Centre for Construction and Engineering Technologies at George Brown College, Toronto, in co-operation with a manufacturer is studying the performance of continuous air barrier, vapour retarder, and fibreglass insulation products.

The construction industry has witnessed an ongoing trend toward large-dimension material panels over the last 60 to 70 years. A pattern of 1.2 x 2.4-m (4 x 8-ft) sheets of oriented strandboard (OSB) and plywood have replaced 0.3 x 3- or 0.3 x 3.6-m (1 x 10- or 1 x 12-ft) shiplap board stock as the sheathing material of choice.
