Foam-LOK Spray-Applied Rigid Polyurethane Foam Insulation Medium Density

Transcription

1 Foam-LOK Spray-Applied Rigid Polyurethane Foam Insulation Medium Density Lapolla Industries, Inc. (Canada) 1870 Albion Rd. Unit 1 Toronto, ON M9W 5T direct fax LAPOLLA direct DESCRIPTION: A Type 1, spray-applied rigid polyurethane foam of medium density. The foams system consists of two components: A component or isocyanate for Foam-LOK, and B component or polyurethane resins. The two components are mixed on site by a certified installer with fixedration positive displacement equipment. The finished product is orange in color by design. EVALUATION: Conforms to CAN/ULC-s (including Amendments 1 and 2), Type 1. A 50-mm thickness of Foam-LOK provides a long-term thermal resistance of 1.8 m².k/w at 50mm. For retrofit construction, time before occupancy is one (1) day. APPROPRIATE USAGE: This product is site manufactured; see preface for more information A third-party organization that operates the field quality assurance program (FQAP) for Foam-LOK spray polyurethane foam insulation has been assigned by Lapolla, Industries.

2 Preface Spray-Applied Rigid Polyurethane Foam Insulation Medium Density Master Format Section: Scope These listings apply to spray-applied rigid polyurethane cellular plastics, medium density, intended for use as thermal insulation for both building and non-building applications, whether applied on a building site or in a prefabricated facility. The thermal insulation shall not be used when the continuous service temperature of the substrate is above 80ºC. The proponent has demonstrated that the product has met at least one of the following standards (see table 1 for their performance requirements): CAN/ULC-S , Standard for Thermal Insulation spray Applied Rigid Polyurethane Foam, Medium Density Material Specification ; CAN/ULC-S , (Including Amendment 1), Standard for Thermal Insulation spray Applied Rigid Polyurethane Foam, Medium Density Material Specification ; or CAN/ULC-S , (Including Amendment 1 and 2) Standard for Thermal Insulation spray Applied Rigid Polyurethane Foam, Medium Density Material Specification ; The product is site manufactured and as per the above editions of CAN/ULC-S , it must be installed in accordance with the manufacturer s instructions and the following appropriate edition of CAN/ULC-S705.2: CAN/ULC-S , Standard for Thermal Insulation Spray Applied Rigid Polyurethane Foam, Medium Density Installer s Responsibilities Specification ; or CAN/ULC-S , Standard for Thermal Insulation Spray Applied Rigid Polyurethane Foam, Medium Density Application CAN/ULC-S refers to the following three key limitations. The spray polyurethane foam shall not be: Used on or in the vicinity of heat emitting devices, such as recessed lighting fixtures, at a lesser distance than 75 mm or as specified by the authority having jurisdiction; Used inside electrical outlets or junction boxes; or Left exposed to continuous ultraviolet light. Users shall consult the appropriate 1998 or 2005 standard editions for additional limitations. For compliance to CAN/ULC-S users should contact the third party organization that has been identified by the foam manufacturer as the third party operating the field quality assurance program of the foam product (see product listing). 2

4 CAN/ULC S Notes to Table 1: (1) CAN/ULC-S (Including Amendments 1 and 2) requires 80ºC instead of 100ºC and a related minimum of 1% and maximum of + 8%. (2) Results are valid for qualification to the standard. As noted in the standard, for building code purposes, the flame spread rating shall be conducted in accordance with the code-specified flame spread test details with respect to number of specimens to be tested, specimens tested intact and cut specimens. (3) CAN/ULC-S (including Amendments 1 and 2) requires that the initial thermal resistance for a 50mm thick specimen be tested after 3 d at 23 ± 2ºC and that the value be reported. No minimum value is required. (4) The conditioned thermal resistance test is required only for CAN/ULC-S (Including Amendments 1 and 2). (5) CAN/ULC-S (Including Amendments 1 and 2) requires a minimum of 1.8 m² C/W to be classified as a Type 1. (6) The oven aged thermal resistance is used for comparative purposes and does not yield a design value for long-term thermal performance. The assigned design thermal resistance is R 6.3 per inch. In cases of retrofit construction (e.g., occupied buildings), CAM/ULC-S requires that ventilation rate of 0.3 air changes be provided within the working area during the application of the product and that the working area be isolated during spraying. The same ventilation rate requirements are required after the product is being sprayed and for the time period determined in accordance with CAN/ULC (see product listing for time before occupancy). (7) To satisfy the maximum water vapour permeance requirement 60 ng/(pa s m²), a minimum of 50-mm thickness of foam insulation must be sprayed over gypsum boards and a minimum of 20-mm thickness of foam insulation must be sprayed over concrete blocks. 4

5 Labeling The standard requires that each liquid component container must be labeled with the following information: Manufacturer s name Product name Type of material (e.g. insulation) Net mass of the contents of the packaged material Lot number Date of manufacture Shelf life The means to identify their installed product; and CAN/ULC-S
