QUESTION: What fasteners should be used with Hunter Panels and Hunter Xci products? ANSWER SIP fasteners are designed for use with Hunter Panels roofing and Hunter Xci wall composite insulation panels. GRIP-DECK CI Screws and Plasti-Grip PMF Anchors are for use with Hunter Xci panels. THE FASTENERS: SIP FASTENERS: XCI INSULATION FASTENERS
When tackling options to reduce overall costs on a tapered roof system, designers look at a variety of specialty products including prefabricated target sumps, prefabricated hips and valleys, and extended panel profiles. The design of your tapered roof system determines if any of these options will benefit your “material cost vs. labor cost” totals. Insulation […]
First, let’s define the two types of insulation we are comparing. Expanded Polystyrene (EPS) is a lightweight, rigid, thermoplastic closed-cell foam insulation. Polyisocyanurate (Polyiso) is a rigid, thermoset closed-cell foam board insulation consisting of a foam core between two facers. Advantages of Polyisocyanurate Over Expanded Polystyrene: Long-Term Thermal Resistance (LTTR)Long-Term Thermal Resistance (LTTR) is a […]
Webster’s Dictionary defines R-value as a measure of resistance to the flow of heat through a given thickness of a material (such as insulation) with higher numbers indicating better insulating properties. The standardized measures of resistance to heat transfer were first recommended in 1945 by Everett Shuman, Director of Penn State’s Building Research Institute. R-values […]
What real world factors can affect a product’s insulating power?
To comply with the International Energy Conservation Code (IECC) requirements for insulating above-grade exterior walls, building professionals can follow one of two commonly used prescriptive methods
Question: How does ASTM C 1289 classify foam insulation? Answer: ASTM C 1289 is a standard developed by ASTM members that classifies the design requirements for a specific material, product, system and service. All faced rigid polyisocyanurate manufacturers are required to manufacture and test to the standards of ASTM C1289. This standard classifies faced polyiso […]
How does the test method work for determining R-value of a building product?
Question: Explain why there may be differences in ASTM E84 flame spread and smoke developed values of foam insulations. Does a lower ASTM E84 value always convey better fire performance? Answer: Some insulation products may have a lower flame spread, but this does not necessarily imply that the product is more fire-resistant. It is important […]
