![]() ![]() Using SIPs also conserves natural resources, because they require fewer raw materials to manufacture them. Because heating and cooling our homes and businesses account for around 40% of our total energy consumption, it is important to implement energy saving components into their construction. A SIP room is 15 times more airtight than a stick framed room using fiberglass insulation. Add in roofing and flooring using structural insulated panels, and you can expect about 40% to 60% energy cost savings per year. SIP walls alone save about 25% of energy loss each year, according to U.S. Environmentally Friendly, Energy Efficient A SIPs structure is also resistant to seismic activity and hurricane conditions. Its airtight construction seals out damaging moisture and eliminates exterior mold issues, warping and nail pops-an issue caused by the wood shrinking and putting pressure on the drywall. The lifespan of a SIP project is 50 years or more, with little or no cost input. The panels are created by sandwiching an insulated foam core with a structural facing on each side. Structural Insulated Panels are extremely strong. That means fewer workers can get the job done faster, which reduces labor costs. On-site waste is reduced, and cleanup is also diminished. Structural Insulated Panels arrive on the construction site pre-cut and ready for installation, cutting back on the time it takes to complete a project. Time costs money on any construction project. Here are three reasons why you should choose SIPs for your home or business construction project: Cost Effectiveness Over the years, these strong, customizable, energy efficient products have improved and evolved into a trusted building material choice for homeowners, builders and contractors alike. The renown and respected architect Frank Lloyd Wright used SIPs in his Usonian house designs back in 1936. PVC pipes as holding containers for the PCMs did not prove as efficient as metal pipes.Since the 1930s, contractors and architects have recognized the virtues of Structural Insulated Panels (SIP) for home and business construction. The results indicate that SIPs with molded expanded polystyrene (EPS) cores would benefit more from the PCM enhancement than SIPs with urethane cores. The PCM outfitted SIPs reduced the peak heat fluxes when compared to their own kind, but without PCM. The two parameters considered (i.e., foam material and pipe material) were found to have first order effects on the performance of PCM-enhanced SIPs. Instantaneous heat transfer rates measurements are presented. This was done through a comparative heat transfer examination of SIPs, with and without PCMs where parameters, such as, foam core material of the SIP and material of the PCM holding containers (i.e., encapsulating pipes) were evaluated. For this, a dynamic wall simulator was built, where a range of important parameters was evaluated. To advance the development of the previous design, which had only been evaluated under full weather conditions, a set of well-controlled laboratory experiments was carried out. ![]() The main focus of this paper was to present data to advance the design of a previously developed thermally-enhanced structural insulated panel (SIP) that had been outfitted with phase change materials (PCMs) (Medina et al., 2008). ![]()
