With increased attention on resiliency and building code requirements of late, the most asked topics are about mildew, flame spread requirements, and how to material storage. Does it spark a question for you?

Our building scientists want to help you succeed.

Mold and mildew are nuisances every architect wants to avoid. We understand that completely. They can grow wherever sufficient moisture, spores, optimal temperatures and nutrients are present.

The key factor is moisture, which can be controlled by adhering to sound construction practices. To make matters worse, condensation can be a source of moisture and a potential contributor to mildew growth. Condensation may occur when water vapor permeates through the wall, cools and condenses on the first cold surface it encounters. One of the ways to manage moisture is to add insulation such that the condensing surface is not inside the wall system.


Walls constructed with proper construction techniques and using an appropriate thickness of insulating sheathing will: They resist moisture absorption in the insulation itself.

This further reduce the potential for mold and mildew growth. To be clear, no building assembly is likely to be completely free from the potential for mold formation, but good building practices unrelated to insulated sheathing will further reduce the potential or mold formation. Ultimately, good construction detailing, compliance with proper installation guidelines for materials, and maintenance of the wall system are key to managing the moisture infiltration into the building envelope.

Use our self-guided Canadian Code Assessment Engine to compare above grade wall strategies for building materials and design methods aligned to local code requirements. The quick answer is: However, Terra cotta, metal panel and fiber cement siding veneers will probably not appreciably increase the R-value of the system.

Our building science experts can perform a customized cost-to-build and performance analysis of your assembly to ensure the building envelope of your project is optimized. Request a report today. As architects have likely heard, density is sometimes used to select a rigid foam insulation material for a particular application.

It should be noted that there are other performance properties listed in ASTM C that are often more important to consider when choosing the proper product for an intended application. Looking at Canada in particular, extruded polystyrene insulation products are covered by the standard ULC S, which does NOT specify a density requirement.


There may be variances among boards. All the weights are for boards of 1″ thickness 1′ x 1′ square. To get weight of 1-inch x 4 feet x 8 feet board multiple the value in table by Example- Thermax Light Duty 1-inch x 4ft x xcoreboard weighs 0. Top 6 Questions Asked about Rigid Insulation. Store above standing water. Keep product tarped or covered to protect from weather.

If possible store product indoors. If product does get wet, allow it to air dry before covering with exterior coverings. Foam boards are lightweight and loose boards can be blown around by wind. Weigh down loose boards until they are securely attached to the structure. For both indoor and outdoor storage adhere to all local building and fire codes.
