     section 01500 (temporary installations).

      .2 Ensure continuous ventilation of the work area, through a fresh air intake and the extraction
     of foul air, during the course of the application process and for 24 hours thereafter.

     .3 Install temporary partitions in order to prevent any effect on the ambient air – outside of the
     work area – from the sprayed on insulation material.

      .4 Ensure all structures are well protected, in accordance with the manufacturer’s
     recommendations.

      .5 Protect all adjacent surfaces and equipment against any damage that may be caused by
     dispersion and overspray of insulation material beyond prescribed limits.

      .6 All remaining foam particles must be flushed out of the spray gun on a daily basis. This
     procedure must be performed in areas designated for this purpose, and the contents of the empty
     containers neutralized according to the procedure established by the BASF.

PART 3 EXECUTION

   .1 Installers of spray polyurethane foam shall be trained by BASF in accordance with CAN/ULC
   S705.2-05 and certified by certified by Morrison Hershfield to install the system specified.

   .1 All excessively wide joints should be covered or filled before applying the polyurethane foam
   .
   .2 Install transition membranes in all places recommended in section 3 of BASF’s technical
   product documentation.

   .3 Install sealant at outside edge of transition membrane at vertical to horizontal membrane
   locations.

   .3 Polyurethane foam should be sprayed with a tolerance of +6/ 0 mm (+¼/ 0 ) in relation to
   the specified thickness.

   .4 Avoid the formation of sub-layer air pockets when applying.

   .5 Avoid spraying the foam on any surfaces other than those indicated. Use drop sheets or
   masking tape to protect other surfaces.

   .6 Once the foam has hardened, remove all overspray from non-prescribed surfaces .

   .7 Do not allow polyurethane foam, once applied, to be damaged during work by the other
   trades.

   .8 Ensure the subsequent coverage of the applied insulating foam will be completed within the
   manufacturer’s prescribed timeframe (refer to BASF’s technical product documentation,
   section 3).

   .9 Spray the polyurethane foam in overlapping layers, so as to obtain a smooth, uniform surface.

            .1 When applying on a flat surface of more than 30 lineal meters (100 lineal feet) in
     either direction, apply the first layer in 3 m (10 ) strips at 1 m (3 ) intervals. After the curing
     period (± 4 hrs.) has elapsed, spray the polyurethane foam on the unfilled spaces.

           .2 In cold weather follow the same procedure for a minimum surface area of 15 lineal
     meters (50 lineal feet).
      GUIDE SPECIFICATION                                                  BASF WALLTITE ECO                     7
                                                           Insulation/air barrier material, air barrier system




             .11 Do not spray polyurethane foam any closer than 75 mm (3 ) from chimneys, heating vents,
             steam pipes, recessed lighting fixtures, and other heat sources. Do not spray the insides of any
             exit openings or electrical junction boxes (refer to the BASF/NECA manual).

             .12 In temperatures below +10°C (+50°F) use transition membranes specifically formulated for
             low temperature application. If required mechanically fasten transition membranes to achieve the
             required pull strength.

             .16 All mechanical fixtures should be covered with polyurethane foam in order to reduce
             thermal bridging. This can be achieved through the use of a galvanized spring clip for drywall,
             screwed 200 mm (8 ) OC through the membrane.


Field Quality Control

             density measurements as outlined by the CAN/ULC S705.2-05 Installation standard. All foam
             installed must have a field density equal to or greater than the density reported in the
             manufacturers published product data and in test reports of thermal resistance.

             .2 The Licensed Installer shall complete the Daily Work Record and record all information
             required including the results of the testing. The Daily Work Record shall be kept on site for
             routine inspection. Copies of the Daily Work Record shall be forwarded to the owner or owner’s
             representative upon request. Copies of the Daily Work Record or monthly summaries shall be
             sent to the BASF Quality Assurance Program office on a monthly basis as required by BASF.

             .3 The costs incurred for daily testing and inspection by the Licensed Installer and the completion
             of the Daily Work Record shall be borne by the Licensed Contractor.

   Inspection
             .1 Arrange for [select 0, 1,2,3] third party site-inspection by Morrison Hershfield as outlined in
             the BASF Canada Quality and Training Program-Raising Performance to New Heights®. The
             cost of inspections shall be included in the bid provided by the Licensed Contractor.

             .2 The 3rd party site-inspection shall verify conformance with the manufacturers instructions, the
             CAN/ULC S705.2-05 Installation standard and this section of the project specification.
