The foam plastic insulation is a two-component, closed-cell, one-to-one by volume spray foam system with a nominal density of 2.0 pcf (32 kg/m3). The insulation is produced in the field by combining a polymeric isocyanate (A component) with a polymeric resin blend (B component). The insulation components have a shelf life of six months when stored in factory-sealed containers at temperatures between 50ºF (10ºC) and 80°F (26ºC). The Heatlok® HFO product meets or exceeds the minimum requirements set forth in Section 2603.1.1 of the 2021 IBC. 3.2 Surface-burning Characteristics: Heatlok® HFO product, at a maximum thickness of 4 inches (102 mm) and a nominal density of 2.0 pcf (32 kg/m3), has a flame spread index of 25 or less and a smoke-developed index of 450 or less when tested in accordance with ASTM E84 (UL 723). There are no thickness limitations when insulation is covered by a code-prescribed 15-minute thermal barrier. ESR-4073 | Most Widely Accepted and Trusted Page 2 of 6 3.3 Thermal Resistance (R-values): Heatlok® HFO product has thermal resistance (R-value), at a mean temperature of 75ºF (24ºC), as shown in Table 1. 3.4 Vapor Permeance: Heatlok® HFO has a vapor permeance of 1.0 perm or greater and less than 10 perms when applied at a minimum of 1 inch (25.4 mm) thickness and may be used where a Class III vapor retarder is required by the applicable code. 3.5 Air Permeability: Heatlok® HFO foam plastic insulation, at a minimum 1-inch (25.4 mm) thickness, is considered air-impermeable insulation in accordance with 2021, 2018, 2015 and 2012 IRC Section R806.5 (2009 IRC Section R806.4) and 2021 and 2018 IBC Section 1202.3 (2015 IBC Section 1203.3) based on testing in accordance with ASTM E283. 3.6 Blazelok TBX or Fireshell® F10E Intumescent Coating: Blazelok™ TBX or Fireshell® F10E intumescent coating (see ESR-3997), manufactured by ICP Construction, is a one-component water-based liquid coating. The coating is supplied in 5-gallon (19 L) pails and 55-gallon (208 L) drums and has a shelf life of (1) year when stored in factory-sealed containers at temperatures between 45ºF (7ºC) and 95ºF (35ºC). 3.7 DC 315 Intumescent Coating: DC 315 intumescent coating (see ESR-3702), manufactured by International Fireproof Technology, Inc., is a water-based coating supplied in 5-gallon (19L) pails and 55-gallon (208L) drums and has a shelf life of one (1) year when stored in factory-sealed containers at temperatures between 50°F (10°C) and 80°F (24°C). 4.0 DESIGN AND INSTALLATION 4.1 General: Heatlok® HFO product must be installed in accordance with the manufacturer’s published installation instructions and this report. A copy of the manufacturer’s published installation instructions must be available at all times on the jobsite during installation. 4.2 Application: The insulation is spray-applied on the jobsite using equipment identified in the manufacturer’s published installation instructions. The Heatlok® HFO product must be applied when the ambient and substrate temperature is between 50ºF (10ºC) and 100ºF (38ºC). The insulation must not be used in areas that have a maximum service temperature greater than 180ºF (82ºC). The foam plastic insulation must not be used in electrical outlet or junction boxes or in continuous contact with rain or water. The substrate must be free of moisture, frost or ice, loose scales, rust, oil and grease, or contaminates that will interfere with adhesion of the spray foam insulation. The Heatlok® HFO product may be applied in passes having a maximum thickness of 61/2 inches (165 mm) per pass. When multiple passes are required, subsequent passes can be sprayed once the core temperature drops below 100ºF (37.7ºC). 4.3 Thermal Barrier: 4.3.1 Application with a Prescriptive Thermal Barrier: Heatlok® HFO insulation must be separated from the interior of the building by an approved thermal barrier of 1/2-inch- thick (12.7 mm) gypsum wallboard or an equivalent thermal barrier complying with and installed in accordance with the applicable code except where the installation complies with the requirements set forth in Section 4.3.2. When installation is within an attic or crawl space as described in Section 4.4, a thermal barrier is not required between the foam plastic and the attic or crawl space, but is required between the insulation and the interior of the building. There is no thickness limit when installed behind a code- prescribed thermal barrier except as noted in Section 4.4.2.1. 4.3.2 Application without a Prescriptive Thermal Barrier: Heatlok® HFO spray foam insulation may be installed without the prescriptive 15-minute thermal barrier or ignition barrier described in Section 4.3.1 or Section 4.4.1, respectively when installation is in accordance with the following: 4.3.2.1 The insulation must be covered on all surfaces with a fire protective coating at the minimum thickness set forth in Table 2. 4.3.2.2 The maximum installed thickness of the insulation must not exceed the thickness set forth in Table 2. 4.3.3 The coating must be applied over the insulation in accordance with the coating manufacturer’s instructions and respective ICC-ES evaluation report for the coating and this report. 4.4 Ignition Barrier – Attics and Crawl Spaces: 4.4.1 Application with a Prescriptive Ignition Barrier: When Heatlok® HFO insulation is installed within attics or crawl spaces where entry is made only for service of utilities, an ignition barrier must be installed in accordance with IBC Section 2603.4.1.6 and IRC Sections R316.5.3 and R316.5.4, as applicable, except when the installation is in accordance with Section 4.4.2. The ignition barrier must be consistent with the requirements for the type of construction required by the applicable code, and must be installed in a manner so that the foam plastic insulation is not exposed. The attic or crawl space area must be separated from the interior of the building by an approved 15-minute thermal barrier as described in Section 4.3.1.

November 9 2023 Hilltop Construction Company 233 Cleverdale Rd, Queensbury, NY 12804 RE: Blower Door Test for NYS Building Code, Tom Albrecht, After inspection of the 2 Story Home at 233 Cleverdale Road, Queensbury, NY and completion of a Blower Door Test consistent with the practice of depressurization to 50 Pascal in a winter condition with the exterior windows and doors shut and the interior doors to all the rooms open, my observations are as follows: ❖ This home tested passed the current New York State Building Code for Air Changes per Hour @ 50 Pascal of less than or equal to 3 ACH/50 (for Homes permitted after November 1", 2016). The tested number is 1.89 ACH/50 Pascal. ❖ The total volume of conditioned space at 233 Cleverdale Road is 48154.4 cubic feet taking into consideration all conditioned space in the home. The cubic feet per minute @ 50 Pascal was 1517 CFM/50. The height correction factor for New York State is 14 for a two-story building, as such the tested home @ 233 Cleverdale Road, has the natural rate of air exchange of 0.1350121395 air changes per hour/natural or 108.3 cfm natural air infiltration credit based on the blower door test. ❖ In the latest(2022)version of ASHRAE 62.2, high-performance homes need to be ventilated at 7.5 cfm per bedroom+ 1, plus 1 cfm per 100 square feet of living space. That means for 4+1 bedrooms it would need 3472 sq ft/100 times 1 cfm= 34.7 cfm + 37.5 cfm or 72.2 cfm total. Since the natural air flow of 108.3 cfm is more than the minimum requirement there is no necessity for continuous mechanical ventilation. It is still advantageous to use the kitchen and/or bathroom fans to help control humidity and improve indoor air quality during the heating season. ❖ My credentials are as follows: ➢ BPI Certified Building Analyst ➢ BPI Certified Envelope Specialist ➢ BPI Certified Heating Professional ❖ If you have any questions regarding my findings, please feel free to contact me.
