Available in PDF, EPUB and Kindle. Book excerpt: Spray Polyurethane Foams in External Envelopes of Buildings presents, for the first time, a book focused on both the theoretical and practical design and applications of spray polyurethane foam (SPF) use. To review the moisture performance of SPF, this book focuses on the design of an assembly where moisture is kept from accumulating and causing deterioration (flow through approach). In this approach, Spray Polyurethane Foam presents two unique parts of theory and practice of various SPF products. FROM THE PREFACE Part 1 of this monograph analyzes SPF performance as the material (product). Being field fabricated, installation of SPF products must include a quality assurance program . . . Laboratory evaluation of foams and their coverings, quality management issues, and quantification of the technical support provided to the SPF contractor are also reviewed. Part 2 presents a systems approach to construction. Starting with principles of environmental control of buildings, different aspects of design and performance of roofing and wall systems are reviewed. Details and design recommendations . . . as well as case studies . . . are included.

Book excerpt: The continuity and integrity of air-barrier systems play a critical role in the performance of exterior envelopes in controlling airflow and vapor transmission. Continuity is essential, particularly in locations along the coast where climates with elevated humidity and high winds exist. In new construction, a continuous air barrier can be achieved by applying materials on the exterior of wall systems, including sheet membranes, fluid-applied membranes, rigid insulations, and spray polyurethane foams (SPF). This method is generally preferred due to the ease of installation and limited detailing concerns. However, in developing and implementing repairs for existing buildings, the application of an air barrier can require repair solutions from the interior due to site conditions, budget constraints, building occupants, or other factors. Sealants, in combination with SPFs, have been successfully utilized in the creation of interstitial (cavity) air-barrier systems along exterior walls. After the construction of three mid-rise multifamily condominiums located in Morehead City, NC, interior damage related to air infiltration began to be reported by building occupants and maintenance staff. Issues included microbiological growth on interior walls and ceilings; condensation along ductwork, registers, and exhaust vents; and air infiltration around windows, electrical fixtures, and wall terminations. The investigation to determine causes of air infiltration, as well as the development and implementation of repairs, are discussed herein. The investigation revealed inadequate detailing around window openings and penetrations in the building envelope, along with incomplete construction of the exterior walls and walkway expansion joints. The improper construction allowed unconditioned exterior air to infiltrate the building envelope. Repairs to create a continuous air barrier included sealing of exterior walls, ductwork, joints between wall framing members, and expansion joints with sealants and SPFs from the interior along with localized reconstruction of exterior walls. Isolated repairs to the existing weather barrier and flashings were also implemented to address moisture infiltration issues.

This book was released on 2014 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the desire for building envelope energy efficiency increases, the sensitivity of the building envelope to small changes in the air, water, and vapor transmission can mean the difference between a functional system and a problematic building. Continuity of the building's air and vapor barrier assembly is critical to insure that the air and vapor transmission remain consistent with the design assumptions and within permissible limits. As a result of the demand for simple, continuous air barriers systems, Spray Polyurethane Foam (SPF) has become a popular choice among design professionals and contractors alike. It is a versatile material that can be applied to either interior or exterior wall systems, providing a useful combination of water, air, and water vapor penetration resistance. However, because the product is essentially fabricated on site by the installer, differences in mixture proportions, thicknesses, ambient and substrate temperatures, moisture or humidity conditions, and other factors can result in dramatic variations in the physical properties of the material, as well as the behavior and performance of the system. One of the most significant problems experienced recently in the use of SPF for air barriers is short and long term shrinkage variations in the foam system, particularly when applied to the exterior of the building. Such shrinkage can result in damage to flashings, closures, and terminations in exterior veneer systems. This document explores the potential causes of excessive shrinkage in SPF systems, the physical changes that can cause the problem, and best practice measures to minimize the potential for significant problems during installation.

Book excerpt: Spray polyurethane foams (SPFs) have advantages over alternative insulation methods because they provide air sealing in complex assemblies, particularly roofs. Spray foam can provide the thermal, air, and vapor control layers in both new and retrofit construction. Unvented roof strategies with open cell and closed cell SPF insulation sprayed to the underside of roof sheathing have been used since the mid-1990s to provide durable and efficient building enclosures. However, there have been isolated incidents of failures (either sheathing rot or SPF delamination) that raise some general concerns about the hygrothermal performance and durability of these systems. The primary risks for roof systems are rainwater leaks, condensation from diffusion and air leakage, and built-in construction moisture. In this project, Building Science Corporation investigated rain and built-in construction moisture and vapor drives. Research involved both hygrothermal modeling of a range of rain water leakage scenarios and field evaluations of in-service residential roofs. Other variables considered were climate zone, orientation, interior relative humidity, and the vapor permeance of the coating applied to the interior face of open cell SPF.

This book was released on 2019 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: Incorporating insulation material with phase change materials (PCMs) could help enhance the insulation capability for further building energy savings by reducing the HVAC loadings. During the phase change process between the solid and liquid states, heat is being absorbed or released by PCMs depending on the surrounding temperature. This research explores the benefits of a polyurethane (PU)-PCM composite insulation material through infiltrating paraffin wax as PCM into PU open cell foam. The new PU-PCM composite provides extra shielding from the exterior hot temperatures for buildings. Through this study, it was demonstrated that PU-PCM composite insulation could potentially help building energy savings through reducing the loads on the HVAC systems based on the building energy modeling using EnergyPlus. The Zero Energy Lab (ZØE) at the University of North Texas was modeled and studied in the EnergyPlus. It is a detached building with all wall facades exposed to the ambient. It was determined that the new PU-PCM insulation material could provide 14% total energy saving per year and reduce the electricity use due to cooling only by around 30%.

Available in PDF, EPUB and Kindle. Book excerpt: Spray polyurethane foam (SPF) insulation increases building energy efficiency by reducing conductive and convective heat losses through the building envelope and is used in both new construction and retrofit applications. Health complaints relating to emissions from SPF installations have spurred a joint industry and federal effort to develop standard methods to quantify airborne emissions from SPF. As part of this effort, the Consumer Product Safety Commission (CPSC) tasked the National Institute of Standards and Technology (NIST) with developing testing and measurement protocols to determine the quantities and properties of compounds released from SPF, such as amine catalysts and aldehydes, as it is applied in residential settings. Specifically, this effort examined if micro-chamber emission results can be used to determine concentrations in indoor environments and to quantify the emissions from a SPF sample that was applied in a potentially non-ideal manner. The data demonstrate that emissions from SPF are chemical, temperature, flow, and foam type dependent. Micro-chamber data can be used to compare chemical emission profiles from various foams, but micro-chamber emission rates for flame retardants cannot be directly applied to full scale emissions in a building. The results from examining SPF in a residential test home suggest that occupants may be exposed to measureable concentrations of the flame retardant tris (1-chloro-2-propyl) phosphate (TCPP) two years after application of open cell foam. CPSC submitted a SPF sample suggestive of being applied in a non-ideal manner. When the submitted SPF was tested in the micro-chamber, over 17 different chemicals were identified with a spectrum match, seven of which had not been previously identified in literature emitting from other foams. Of the chemicals for which concentrations were quantified in the micro-chamber experiments, triethylenediamine concentrations were the highest. The emission rates of six chemicals were quantified from the SPF. The emission rates of all chemicals except for TCPP decreased in a negative exponential manner. More information on chemicals emitted from SPF in buildings are needed to determine if the tested foam is indeed a misapplied foam. Emission rates in this document apply only to micro-chamber conditions. This data should not be used to predict full-scale emissions until further testing has determined mass transfer parameters.

Available in PDF, EPUB and Kindle. Book excerpt: Urethane or polyurethane foam is the second most widely used rigid plastic in the construction industry. One of its unique properties -- its high strength to weight ratio -- makes it the strongest of all the common foam plastics. It comes in a variety of forms: rigid or flexible, low or high density, open or closed celled. It is normally used in a rigid closed celled form for building insulation. Both factory-made board stock and spray-on types are being used more extensively as insulations in building construction. Urethane foam is an effective material but there are limitations that must be understood if it is to perform effectively. This Note has been prepared in an attempt to aid that understanding.
