3.04INSTALLATION

3M CANADA GUIDE NOTE: Refer to the weather barrier manufacturer’s current installation guide for detailed information regarding installation.

.1Install weather barrier in accordance with sheet manufacturer’s written recommendations.

.2Install only when substrate temperature is above minus 18 ºC.

3M CANADA GUIDE NOTE: Buildings are designed to accommodate thermal and seismic movement. 3M™ Self-Adhered Air and Vapor Barrier Membrane 3015 must be installed to allow this movement throughout the life of the structure.

.3Thermal and Seismic Movement:

.1Limit coverage area of weather barrier to single storey and shingle subsequent layers over top leading edge of weather barrier to accommodate thermal and seismic movement.

.4General Weather Barrier Installation:

.1Pre-cut weather barrier into individual manageable lengths for installation by pulling weather barrier off main roll to desired length.

.1Cut weather barrier square to factory edges.

.2Minimum dimension in each direction: 100 mm.

.3Wind cut lengths into a separate roll for ease of handling and installation.

.2Fold starting edge back over itself to crease paper release liner.

.3Peel back liner to expose 50 to 75 mm strip of adhesive side of weather barrier.

.4Apply weather barrier to substrate as soon as adhesive side of weather barrier is exposed.

.1Ensure accurate initial alignment and positioning since repositioning after initial contact is difficult.

.2After initial adhesive strip of weather barrier is aligned and positioned, set weather barrier by rolling material back against exposed adhesive.

.5Start at lowest point and work to top, running length of sheets horizontally and overlapping upper sheets in shingle fashion

.1Ensure sides and ends of sheets have [50] mm minimum overlap.

.2Ensure inside and outside corners have 150 mm minimum overlap.

.6Install sheets without gaps, wrinkles, creases or tears.

.7Stagger vertical seams from floor to floor or separate floors using horizontal strip of weather barrier.

.8Unwind roll while simultaneously pulling release liner.

.1Maintain pressure against substrate to ensure adhesion.

.2Wipe weather barrier down from middle to outer edges using feathering motion to ensure smooth surface.

.9Align and overlap layers.

.10Flash and seal top edges, around openings and penetrations, and other locations in accordance with weather barrier manufacturer’s written recommendations.

.11Roll weather barrier with rubber roller to ensure tight seal to substrate.

.1Give extra attention to overlaps, joints and exposed edges of weather barrier sheet.

3.05penetrations

3M CANADA GUIDE NOTE: Weather barrier can be applied around penetrations either before or after the main weather barrier sheets have been installed. However it is recommended the weather barrier be installed around penetrations and openings before the main sheets are installed for extra protection from the elements.

.1Penetrations - General: Install weather barrier around penetrations before application of main weather barrier sheets.

.1Ensure weathertight seals at joints.

.2Window and Door Openings:

.1Cut weather barrier detail strips from main roll to lengths suitable for opening size.

.1Remove first 50 - 75 mm of release liner and align and position weather barrier detail strips to each sill corner.

.2Ensure detail strips extend to full depth of sill and 50 mm minimum to jamb, sill and face of opening.

.3Overlap joints 50 mm minimum.

.2Sill Wrap: Apply appropriately sized piece of weather barrier to bottom of opening, folding into opening to form sill and dams.

.1Ensure joints are overlapped 100 mm minimum to exterior face.

.3Jamb Wrap: Apply appropriately sized pieces of weather barrier to opening jambs extending 100 mm minimum from opening to exterior face.

.1Fold into opening and shingle lap over previously installed sill wrap.

.4Head Wrap: Apply appropriately sized pieces of weather barrier to opening head extending 100 mm minimum from opening to exterior face.

.1Fold into opening and shingle lap over previously installed jamb wraps.

.5Roll weather barrier overlaps and edges with rubber roller to ensure adhesion and smooth surface finish.
