It is crucial to have enough depth for the moisture-resistant insulation you are going to use. Grading:...

Why is it important to insulate under concrete floors in basements and heated garages?

Heat moves from hot to cold. If you insulate all areas in your home with high R-value materials but fail to insulate the underside of your concrete floors, heat will escape through the ground. Many people don’t think about it, but heat in your home does heat walls, floors, and furnishings. This is why it is sensible to insulate the...

How much R-value should be installed under concrete floors in basements?

Although the Ontario Building Code (OBC) does not require insulation to be installed under non-heated floors in garages, basements, or other rooms, the OBC does require insulation to be installed under heated floor systems. It is, however, best practice to insulate and isolate the entire building envelope. The entire building envelope includes the ground. The OBC requires R10 be installed...

What are the benefits of installing insulation to the ground before installing concrete?

There are a few benefits of installing insulation to the ground before installing concrete over top. Concrete slabs stay dry: Ambient temperatures and moisture are more readily controlled, which stops floors from sweating. Dry floors mean easy cleaning and control of bacteria and mold. Energy savings: Building codes‎ have for the longest time focused on increasing the thermal efficiency of...

How does under slab insulation reduce moisture movement from the ground?

Under slab or under concrete insulation are composed of low permeation materials and therefore resist moisture. Because our under slab insulation for concrete floors will resist moisture, the room in which the floor insulation is installed will be comfortably dry. This is why INSTA-PANELS® are great in garages, basements, and lived-in areas. Please note, it is best practice to ensure...
