3 – Execution
3.1 Substrate Preparation
The substrates to which the insulation is applied must be clean, dry, and free of frost, ice, loose debris, or contaminates that will interfere with adhesion of the spray foam insulation. The insulation must not be applied in electrical boxes.
a) Plywood shall contain no more than 18% water, as measured in accordance with ASTM D-4449 and 4444-84.
b) Most untreated and unpainted wood surfaces need not be primed. The spray polyurethane foam can be applied directly to the dry wood. Priming may be required in certain instances. Contact a manufacturer’s representative for specific details.
a) Primed steel must be free of loose scale, rust, weathered or chalking paint.
b) Bare metal can be cleaned using vacuum equipment and hand or power tools to remove loose dirt. Grease, oil, and other contaminants should be removed with appropriate cleaning solutions.
3.1.3 Concrete & Masonry
Must be cured and loose dirt and any other contaminants, such as asphaltic materials, removed. If a primer is required, prime with red oxide primer, at the rate of one gallon per 200 square feet.
3.1.4 Sheathing Board
Most sheathing boards need not be primed prior to the application of sprayed-in-place polyurethane foam.
3.2 PRIMER APPLICATION
When required, the primer shall be applied to the properly prepared substrate in accordance with the manufacturer’s guidelines to achieve a minimum thickness of dry mils. Many primers require a curing time of 24 hours prior to application of spray polyurethane foam or other products. Refer to the appropriate primer data sheet for application procedures.
3.3 SPRAY POLYURETHANE FOAM APPLICATION
3.3.1 The spray polyurethane foam components (A) and (B) shall be processed in accordance with the instructions found on the appropriate product data sheet.
3.3.2 Applicators must recognize and anticipate climatic conditions prior to application to ensure highest quality foam and to maximize yield. Ambient air and substrate temperatures, moisture, and wind velocity are all critical determinants of foam quality. Variations in ambient air and substrate temperature will influence the chemical reaction of the two components, directly affecting the expansion rate, amount of rise, yield, adhesion, and the resultant physical properties of the foam insulation. To obtain optimum results, closed-cell and open-cell spray polyurethane foam should be spray-applied to substrates when ambient air and surface temperatures fall within a range of 50ºF to 120ºF. Closed-cell for cold weather climates should be spray-applied to substrates when ambient air and surface temperatures fall within a range of 50°F to 120°F.
3.3.3 The open-cell spray insulation at a maximum thickness of 6 inches (102 mm) and a nominal density of .5lb pcf, has a flame-spread index of 25 or less and smoke developed index of 450 or less when tested in accordance with ASTM E84. Applicators should limit open-cell thickness to 6 inches per pass for optimal processing and physical properties. Second passes if necessary should be applied after 10 minutes of cure time. If additional passes are needed, applicators should wait 30 minutes between passes for optimal foam processing. Thicknesses up to 12 inches (305 mm) in wall cavities and 12 inches (305 mm) in ceiling cavities are recognized based on room corner testing in accordance with NFPA 286. Thicknesses up to 7 inches (178mm) for wall cavities and 15 inches (381mm) for ceiling cavities in attics and crawl spaces are recognized based on diversified fire tests.
Applicators should limit closed-cell foam thickness to 2” per pass for optimal processing and physical properties. Second passes if necessary should be applied after 10 minutes of cure time. If additional passes are needed, applicators should wait 30 minutes between passes for optimal foam processing.
3.3.4 Spray Foam Application must be installed with a Thermal Barrier and must be installed in a manner so that the foam plastic insulation is not exposed to the interior.
3.3.5 Application with Minimum ½” Gypsum Board. In attics, spray foam insulation may be spray-applied to the underside of roof sheathing and roof rafters. In crawlspaces, closed-cell spray foam insulation may be spray-applied to the underside of floors as described in this section.
3.3.6 Use on Attic Floors: Spray foam insulation must be separated from the area beneath the attic by an approved thermal barrier.
3.4 Vapour Retarder Application
3.4.1 When less than 2.0” of foam is applied a vapour retarder shall be applied to the substrate to be insulated or to the finished spray polyurethane foam insulation. The predominant direction of the vapour drive determines the location of the vapour retarder relative to the spray polyurethane foam.
3.4.2 A minimum of two inches of closed-cell foam constitutes a vapour retarder – where permitted by code.
3.4.2 Apply thermal barriers and vapour retarder (if required) according to local building code recommendations.
3.5 Thermal Barrier Application
The NBC codes require that SPF be separated from the interior of a building by a thermal barrier, which is applied over the SPF to slow thermal rise during a fire, and delay its involvement in a fire. A building code definition of an approved thermal barrier is one that is equal in fire resistance to ½ inch gypsum board. Thermal barriers limit the temperature rise of the underlying SPF to not more than 121°C (250°F) after 15 minutes of fire exposure in compliance with ASTM-E119 (Test Methods for Fire Tests of Building Construction Materials). Thermal barriers meeting this criterion are termed a “15 minute thermal barrier” or classified as having an “index of 15”. QAP recommends that an approved thermal barrier separate spray polyurethane foam from the building interior unless waived by a local building code official. There are exceptions to the thermal barrier requirement: (1) Code authorities may approve coverings based on fire tests specific to the SPF application. For example, covering systems that successfully pass large scale tests may be approved by code authorities in lieu of a thermal barrier; (2) SPF protected by 1” thick masonry does not need a thermal barrier. Certain materials that offer protection from ignition, called “ignition barriers,” may not be considered as thermal barrier alternatives unless they comply with ASTM E-119. Just because a material is advertised as a “thermal barrier” or “ignition barrier” does not mean that it has been tested in conjunction with SPF and approved by a code agency or a local code official. Applicators should request test data and code body approvals or other written indications of acceptability under the code to be sure that the product selected offers code-compliant protection.
At the end of each work day, remove rubbish, empty containers, rags, and other discarded items from the site. After completing work, clean glass and spattered surfaces.
