Occupant comfort, both thermal and acoustical, is an essential component of indoor environmental quality. PGF Insulation’s products help maintain a consistent air temperature throughout the building, absorb noise and conserve energy. They also help to keep out air that can bring with it unwanted moisture. Moisture is the most important controllable element in the fight against mold. Our insulation, along with a vapor retarder, help prevent condensation that can lead to mold and corrosion by keeping outside air out. Thermal Insulation By reducing heat transfer across the duct system, our products allow a building’s HVAC system to deliver conditioned air at design temperatures. In the walls and ceilings, our glass wool insulation resists the flow of heat. Heat is a form of energy — it always seeks a cooler area — flowing outward in winter and inward in summer. By reducing heat flow, a properly insulated building increases overall occupant comfort while maintaining lower energy costs. Acoustic Insulation In the Built Environment By far the easiest and most economical method for controlling noise is to install insulation in the wall cavity. Glass wool insulation is an excellent sound absorber as well as an energy saver. When installed in the walls and ceilings, it can reduce the transmission of sound from other rooms or from the outside. Adding insulation beneath drywall in a typical wall configuration can reduce sound transmission significantly. If a new wall is being constructed, homeowners can also build what is called a resilient channel between the drywall and the studs or joists. Properly installed resilient channels will break the noise vibration path, providing a dramatic reduction in sound transmission. In HVAC Systems Without glass wool insulation products, the acoustical environment of mechanically conditioned buildings can be greatly compromised. Our products greatly reduce the transmission of HVAC equipment and airflow generated noise through the duct system. They also reduce cross talk from one room to another through the ducts. Condensation Controls In Building Structures In order to minimize potential condensation problems in attics, floors, and walls, three things need to occur: • Sufficient ventilation to reduce excessive water vapor build-up within the home. • Ventilation of building sections so that excessive water vapor is dissipated to the outdoor air. • Use of vapor retarders to limit water vapor transmission into building cavities. A vapor retarder attached to batt or roll insulation decreases the possibility of moisture vapor condensing to water within the structure. In HVAC Duct Systems PGF Insulation’s duct liner, wrap, board and flexible duct reduce condensation on duct surfaces, thus reducing the opportunity for microbial growth and amplification as well as other moisture related building damage. Condensation will form on any duct surface with a temperature equal to, or lower than, the dew point temperature. The moisture may remain in place or drip, causing moisture damage and creating a potential for microbial contamination. Our duct liner, duct wrap, flexible duct and duct board reduce the opportunity for condensation, thus eliminating the critical precondition for microbial growth.       | Contact Us
