1 Description

Carlisle’s Sure-Weld roofing systems utilize a material which offers high resiliency and reflectivity, with the added benefits of heat-welded seams. Heat-welding fuses individual sheets of membrane, creating a monolithic assembly and a consistent, smooth appearance.

The Sure-Weld membrane provides long term ultraviolet and ozone resistance, and is environmentally friendly because it is compounded without chlorine. It is available in fully adhered and mechanically attached systems, with Factory Mutual, UL and ULC approvals.

Sure-Weld Roofing Systems utilize either a .045" or .060" thick reinforced thermoplastic polyolefin membrane. The membrane is supplied in 8 and 10 foot widths, and is available in white and grey.

1.1 GENERAL

The roofing system / material information published in the RCABC Roofing Practices Manual does NOT represent a complete set of the manufacturers published data, nor does it represent a detailed specification. The preparation of a detailed specification is the responsibility of the design authority.

SYSTEM DESCRIPTION/ RANGE OF APPLICATIONS

.1 Sure-Weld roofing systems are intended for installation on commercial, industrial, and institutional projects. These systems can be used in both new construction and re-roofing.
.2 Can be installed over most roof decks / substrates (steel, wood plank, plywood, OSB, pre-cast, poured in place and lightweight concrete, etc.).
.3 The mechanically attached system has a maximum slope limitation of 18 inches of rise in one horizontal foot. There is no maximum slope restriction on the fully adhered system.

DELIVERY, STORAGE AND HANDLING

.1 Deliver materials to the job site in the original, unopened packaging.
.2 Store Sure-Weld accessories in a dry protected areas between 60 and 80 degrees F. Lids on all containers must be securely closed. Store the Sure-Weld membrane in the original wrap.
.3 Insulation and underlayment must be stored so it is kept dry and is protected from the elements.

SITE CONDITIONS

.1 Slopes
Minimum slope:
  • the roof system assembly should be designed to prevent ponding of water on the roof for prolonged periods (longer than 48 hours).
Maximum slope:
  • Mechanically fastened: 18" in 12"
  • Fully adhered: no restriction
.2 Application Temperature:
  • minimum: - 30 degrees C
  • maximum + 40 degrees C
The temperature range for accessory items may vary. Contact manufacturer for details.
.3 Chemical Incompatibilities:
Petroleum based products, certain chemicals and waste products may not be compatible with the Sure-Weld roofing system. Carlisle must be contacted for verification of compatibility.

STANDARDS AND APPROVALS

.1 Factory Mutual: FM 1-60, 75, 90, 105, 120
.2 Underwriters Laboratories: Class A & B
.3 Underwriters Laboratories of Canada: Class C
For ratings on specific roof assemblies consult Carlisle SynTec Canada.

MANUFACTURER’S SERVICES

.1 Sure-Weld roofing systems are installed by Carlisle trained and authorized roofing contractors. Carlisle Technical Specialists provide contractor authorization training, upgrade training, on site training, technical assistance, and inspections.
.2 Carlisle’s technical and sales personnel are available to provide assistance to roof designers.

1.2 MATERIALS

1.3 EXECUTION

SUBSTRATE PREPARATION

.1 On retrofit-recover projects, cut, remove and replace wet insulation.
.2 Substrate must be even without noticeable high spots or depressions, and must be free of water, snow, and / or ice.
.3 Clear the substrate of debris and foreign material. Roof cement must be removed.

INSULATION INSTALLATION

.1 Selection of suitable insulation, insulation thickness, and fastener frequency are selected based on project specifics. Options are based on Carlisle’s Design Criteria, code approvals, and project specifications. Consult Carlisle for specifics.
.2 Insulation shall be fastened in accordance with specifications.
.3 Sweep loose debris from substrate.

INSTALLATION OF MEMBRANE ON MECHANICALLY FASTENED SYSTEMS

.1 The type of fastener and plate for securing the membrane is determined by deck type.
Consult Carlisle specification for details.
.2 Sheet size (8 and 10 foot), number of perimeter sheets, and fastener frequency are based on the specific requirements for the individual project.
.3 Position perimeter sheets along the perimeter of the roof. Five (5) foot wide perimeter sheets are used with 10’ field sheets, 4 foot perimeter sheets with 8 foot field sheets. A minimum of one (1) perimeter sheet is required.
.4 Position adjoining sheets to allow for an overlap of approximately 5-1/2" at those locations where Fastening Plates are located (along the length of the membrane), and a minimum of 2" for the splice at end of the roll.
.5 Secure the membrane at the approved fastening density with the required fastener and plate.

INSTALLATION OF MEMBRANE ON ADHERED SYSTEMS

.1 Position Sure-Weld Membrane allowing for a minimum 2" overlap. Fold back so half of underside is exposed.
.2 Apply Sure-Weld Bonding Adhesive to both the membrane and the substrate, keeping adhesive out of the splice area.
.3 After adhesive has flashed off, roll the coated membrane into the coated substrate. Immediately brush down the bonded section to ensure full contact.

HOT AIR WELDING

.1 Hot air weld the Sure-Weld membrane sheets using the Automatic Hot Air Welding Machine, or Hand Welder and silicone roller.
.2 Consult Carlisle specifications for details of welding procedures, requirements for test cuts, and equipment.
.3 All seams are to be probed and repairs made at the end of each working day.

DETAIL WORK

.1 The membrane must be secured at the perimeter of each roof level, roof section, expansion joint, curb, skylight, or other penetration, or angle change over 2 in 12. Refer to Carlisle Sure-Weld specifications and details.
.2 Flash all wall and curbs with Sure-Weld reinforced membrane.
.3 Non-Reinforced membrane shall be limited to inside and outside corners, field fabricated pipe seals, scuppers, and Sealant Pockets where the use of pre-molded accessories are not practical.
