If it's applied to seal small gaps then it may be fine, if it's applied on a surface (say, covering an entire rim joist) or to fill a void then it probably isn't.įlofloflo, if all you're trying to do is seal small gaps, you could consider a caulk, firestop-type or not.įlofloflo, if all you're trying to do is seal small gaps (1/4" or less), you could consider a caulk, firestop-type or not. The difference is entirely in how it's applied. As you say, it's for use in fire separations. It doesn't mean the product can be left unprotected, per se. As always the devil is in the details.ULC designation is what's required in Canada, generally. Visit the General Building Information page for changes to the building permit application process and inspections. That doesn't necessarily mean it isn't a risk of creating toxic smoke within an area which may still require mechanical protection from ignition. Call 51 or email buildingwaterloo.ca to book an appointment. The trouble that I see is fireblocking is used to block the spread of smoke and flame through a fire separation. I would still contact my local building department to see what their view is on the matter since if, heaven forbid, there ever is a fire in your house the insurance company will be contacting them to find out if the product was used in an approved manner. You should be able to leave this product unprotected. I went on the "great stuff" website and they claim that the product is UL listed which means it's been tested to meet the BC for use in fire separations. Steel can be protected with something called intumescent paint which forms a heat-resistive barrier, but that's not something you can use on sprayfoam. firestops prevent the spread of fire via penetrations (like a water pipe or electrical conduit through a wall) but often have a maximum gap width for what they are filling - they react to heat by expanding or solidifying, so are limited in how they can be applied.

It reads more like a firestop than a fire-rated insulation product. These items help reach the fire safety and sound requirements set out in the Ontario building code. In terms of the product you're referencing - you'd be best to reach out to the manufacturer to determine its suitability. Thermax brand polyisocyanurate foam has passed certain fire ignition tests and is therefore approved by many building departments for installation in crawl spaces without any addition protection. It also refers to section 3.1.5.12.(2)(e), which you have to read alongside the product you are using because there are different requirements for products with different flame spread ratings. Presumably, code officials also permit the installation of thicker versions of any of the six listed materials. Please contact CertainTeed prior to using an alternate method of installation.The relevant sections of the Ontario Building Code are 9.10.17.10 - Protection of Foamed Plastics, which refers to 9.29.4 - 9.29.9 for acceptable barriers (see Chimera's post, but the code spells out exactly how these need to be installed).

If so, cut the insulation and facing to a width equal to the clear opening dimension between the furring strips plus 11/2", then cut back the insulation 11/2" in order to form a stapling flange at the bottom. The second roll may have to be cut to fit. Staple a second roll of insulation to the center and lower furring strips.

Full wall application: Fasten a third row of 2" x 2" furring, 1/2" to 1" from the floor. Roll out the insulation and staple to the upper and lower furring strips with the facing exposed. The 48" or 72" measurement must be the clear opening between both rows of furring. Fasten a second row of 2" x 2" furring with power-actuated fasteners 48" or 72" below the sill plate furring, depending on the width of the insulation used. Half-wall application: Nail a 2" x 2" furring strip to the edge of the sill plate at the top of all walls to be insulated. Want to use rigid pink foam boards for concrete 1.5'' (R7.5) and batt insulation for wall (R14). Basement Wall Insulation is installed horizontally either half-wall or full wall, starting at the sill plate. Trying to figure out building code for Ontario what R value and what insulation along with vapor barrier is up to code. Check your local building code requirements.
