![]() Lumber can represent up to 25% of a wall section, thus reducing your overall R-Value. SIP Whole Wall When measured as a "whole wall", Oak Ridge National Laboratories found that a 4.5" SIP wall actually out-performs a 2圆 wall (studs 24" o/c) with fiberglass batt. ENERGY TEST HOME: 3,000 SF 42 Windows 11 Skylights Their annual estimates are shown on the table below. Louisville Gas and Electric and the Trane Company did energy audits on the home based on similar sized homes in the area with fiberglass insulation. Using 4.5 inch wall panels and 6.5 inch roof panels to construct his home, he set up meters on the house to separate his heating and cooling from lights, water heaters, and personal electric. In 1996, Fred Fischer built his home with SIPS panels. R-Value Comparison to fiberglass: Panel Thickness:Ĭonsider this example. Without these negative effects, actual R-Value of insulation within a SIPS panel can actually exceed its determined R-Value. ![]() SIPS homes avoid these familiar problems by distributing insulation uniformly among the entirety of the panels. When taking into account factors such as cavity voids, wiring without compression, and paper facer stapled to studs, the actual R-Value decreases significantly. However, studies have shown that determined R-Values have little correlation with how an insulating material actually performs in a non-SIP home. Insulating materials with a higher R-Value correspond with increasingly better performance. Insulation is rated by R-Value, which measures a material’s thermal resistance. The long life cycle that composites afford means the initial costs are spread over a longer period of time and the reduced maintenance is an added benefit.The type of insulation you choose can result in thousands of dollars saved in utility bills over the life of your home. Severe weather, moisture, and insects do not degrade homes made from composites. Are available in lengths exceeding 24 feet (the maximum available in an OSB panel)Ĭomposite houses and the composite housing market is growing rapidly.Not attacked by insects (especially termites).Provides no food source for mold growth.Dimensionally stable (won’t shrink or swell).Will not ignite (phenolic has 1/20th the flammability of wood and fiberglass is fireproof).Panels made with our composite phenolic laminates are often referred to as CSIP or FSIP standing for Composite Structural Insulated Panel or Fiberglass Structural Insulated Panel.ĬSIPs have distinct advantages over traditional OSB wood faced SIPs. Phenolic skins laminated to honeycomb cores when superior strength required The resulting panels have a very high strength to weight ratio and can be engineered to meet most structural design loads. The basic cores used are EPS, urethane, balsa, and honeycomb made from paper, plastic, or metal. The laminate is used as the skin or facer and bonded to a core of various thicknesses to meet structural and R value needs. DuraSip Phenolic Fiberglass Laminate SheetsĮmail: majority of our phenolic fiberglass laminates are used to manufacture structural insulated panels or SIPs.
