The difference between COMFORTBATT® and ROXUL SAFE 'N' SOUND™ is density (weight) and batt size. ROXUL SAFE 'N' SOUND™ is denser than ComfotBatt® and is manufactured to an approximate 3 inch thickness.
SAFE 'N' SOUND™ is intended for acoustical and added fire resistance in interior wall applications. Interior walls have no R-value requirements so R-value information is not tracked or published for SAFE 'N' SOUND™. We recommend COMFORTBATT® and ROXUL PLUS® be used in applications requiring thermal value.
Yes, the insulation will pass building code inspections as ROXUL tests to CAN/ULC S-702 Standard For Mineral Fibre Thermal Insulation For Buildings, and ASTM C665 Standard Specification for Mineral-Fiber Blanket Thermal Insulation for Light Frame Construction and Manufactured Housing as required by the NBCC (National Building Code of Canada), the ICC (International Code Council) and IBC (International Building Code) . In addition, there are CCMC numbers on the COMFORTBATT® and ROXUL PLUS® products. As a result, ROXUL has met all the criteria needed for Canadian and United States residential codes.
Yes, COMFORTBATT® is designed for your exterior walls and attics. Code requirements for attic R-value will vary from province to province, although, R-40 is quite common. To achieve R-40 in your attic using COMFORTBATT®, it is recommended to use two layers of R-22 for a total of R-44. Lay the first batt between the roof trusses, then the second layer perpendicular to the first so as to cover up the roof trusses.
Insulating around pot lights can vary by manufacturer, as well as the type of pot light and it may be covered under your local building codes. ROXUL has no set requirements for insulating around pot lights and would always recommend following the manufacturers recommendations and/or your local building codes.
