Spray Foam Insulation FAQs
Does spray foam insulation need to be covered in Ontario?
In most cases spray foam will need to be covered with a thermal barrier in order to be code compliant. 1/2″ drywall is an acceptable thermal barrier. In situations where drywall will not be used we can apply a coating called DC315 in order to meet thermal barrier regulations.
Does spray foam insulation need a separate vapour barrier?
BASF Walltite Eco is a 2lbs medium density foam that is classified as a vapour barrier under the Canadian Building Code at any thickness over 1″. There fore spray foam does not need a separate vapour barrier.
Can you drill and fill existing wall cavities?
No. Due to the rapid expansion and exothermic properties of 2lbs spray foam it is not suitable for filling large cavities. Furthermore without being able to see what obstacles may be present in the wall its impossible to do a quality job without first removing the drywall.
Can spray foam be applied year round?
Yes. For the most part spray foam can be applied year round. Extremely cold days, and extremely wet days are the main exceptions to that rule. When you contact us to plan your project we will discuss the measures, if any, required to ensure your job site is within the temperature and moisture parameters of the foam.
How far does the spray foam gun reach?
Generally we need a minimum of 3 feet of work space from the substrate. Due to the way the equipment works there is no way to add an additional reach wand of any sort.
