PRIMERS
Use primers as per manufacturer recommendations and CAN / ULC-S705.2 for surface conditions.
For oily metal surface like Z-Bar, steel deck roof or curtain wall pan, aluminium tube, and PVC, applied ADBOND 8388-1 adhesive primer, colour: red before spraying polyurethane foam.
2.5 EQUIPMENT
Equipment shall be as recommended in CAN/ULC-S705.2 and approved by foam manufacturer for type of application.
PART 3-EXECUTION
Note: Check the adhesion and compatibility with: flashing, membranes, coatings, and respect DEMILEC typical details drawing. 3.1 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.
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.
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.
If the thickness of application is greater than 50 mm, detail membrane around opening need to be made in accordance to DEMILEC typical details. Drawing are available on www.demilec.com or contact your representative. Option use mechanical fastener to secure self-adhesive membranes around openings only (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
Note: Refer the mechanical fastener to the appropriate section (07 27 00) for coordination.
All oily metal surface like Z-Bar, steel deck roof or curtain wall pan, aluminium tube, and PVC, shall be primed as mentioned in CAN / ULC S705.2 art: A 1.7.
Note: See DEMILEC drawing. Refer that alternative to the appropriate section (07 42 00) for coordination. B) If required, all spray applied membrane shall be installed before the “Z” bars.
Respect the moisture content of the different building materials.
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.
3.2 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 above -20 C. Refer to technical data sheets.
Apply in consecutive passes (min. 15 mm, max. 50 mm) to obtain the thickness as indicated on drawings, or ( mm) for wall, ( mm) for roof to achieve the required thermal insulation value. Use only the Long Term Thermal Resistance (LTTR) CAN/ULC S 770 test method to calculated design R value.
Do not spray closer than 3” (75 mm) of chimneys, recess spotlight or other source of heat.
3.3 TOLERANCE
Apply the product to achieve an average thickness of ± 6 mm (1/4”), from (9 readings in 1 M2), of the thickness requirements in the drawings at a minimum of 1 M2 readings for each 150 m2 surface sprayed.
Apply the insulation uniform in accordance to NBC article 9.25.2.3. 1).
3.4 FIRE PROTECTION
Any open flame or welding that is not allowed to be in contact with the Spray Polyurethane Foam in place. Use protection as required in CAN / ULC S705.2.
All plastic insulation must be protected from interior occupancy space by an approved thermal barrier to meet the requirements of local Building Codes (See section 07 81 16).
Note: Work related to thermal barrier installation should be specified under appropriate sections. ----------------------------------END OF THE SECTION-----------------------------------------------
