EXECUTION
EXAMINATION
• Verify that surfaces and conditions are suitable to accept work as outlined in this section.
• According to the prescriptions of the standard CAN/ULC-S705.2 verify the conditions of surfaces.
.1 Surfaces to be covered with spray foam shall be free of an excess of moisture, frost, oil, rust, and any other foreign material able to have a negative affect on the adhesion of the product.
.2 Make sure of the complete cure of the substrates: concrete, mortar, fillers, membranes, primers, coatings or other surfaces, before pulverizing, taking into account climatic conditions.
.3 If the thickness of application is greater than 50 mm use mechanical fastener to secure self-adhesive membranes around openings (galvanized steel angle: 13 mm x 25 mm x 0.42 mm in thickness (gypsum corner bead). Fixed at 400 mm C/C. ALTERNATIVE: Follow DEMILEC typical details or contact your representative.
• Respect the moisture content of the different building materials.
• In the case of particular conditions follow the recommendations of the manufacturer
• Report in writing, any defects in surfaces or conditions that may adversely affect the performance of products installed under this section to the consultant before commencement of work.
• For occupied building application confirm that all requirements in Article 1.11 are in place.
• Commencement of work outlined in this section shall be deemed as acceptance of existing work and conditions.
APPLICATION
• Spray application of polyurethane foam shall be performed in accordance with CAN/ULC-S705.2. Standard for Thermal Insulation Spray Applied Rigid Polyurethane Foam, Medium Density, Installer’s Responsibilities.
• Apply only when surfaces and environmental conditions are within limits prescribed by the material manufacturer. Refer to technical data sheets.
• Do not spray closer than 3’’ (75 mm) of chimneys, recess spotlight or other source of heat
TOLERANCE
• Apply the product to achieve an average thickness of ± 6mm (1/4’’), from (9 readings in 1 M2), of the thickness requirements
• Apply the insulation uniform in accordance to NBC article 9.25.2.3. 1).
FIRE PROTECTION
