Three common continuous mineral fibre myths debunked
(04/05/2017)
It can be difficult to sort through the falsehoods about mineral fibre insulation to find the truth. How does it really perform in the face of wind-washing, water infiltration, and cold temperatures?
The 2015 National Building Code of Canada (NBC) brought about multiple changes. One of the most important from an insulation standpoint is the treatment of the language concerning RSI values. (Although most in the...
When designers are deciding which insulation products to specify for a given project, two questions come to mind: ‘What is the R-value?’ and ‘What is the permeance?’ The answer to both these queries is,...
The Polyisocyanurate Insulation Manufacturers Association (PIMA) developed a research report in response to recent articles questioning the thermal performance of polyiso roof insulation in colder climates. According to “Thermal Resistance and Mean Temperature: A...
The effect of temperature on insulation performance
(05/28/2015)
On the surface, R-value is a simple thing. In fact, it has become the standard metric of thermal performance precisely because it is easy to explain and understand. Most insulation materials have ‘label R-values’...
Reducing energy consumption with exterior sheathing
(10/01/2012)
With the ever-increasing demand for efficiency in new buildings, as well as the retrofitting of existing facilities, exterior sheathing plays an integral role in reducing energy consumption and the associated carbon dioxide (CO2) emissions....
