3/20/2023 0 Comments Does closed cell foam absorb water![]() ![]() NBR insulation is made of sheet and there are various materials, including fiberglass, foam rubber and polyethylene foam, all of which offer the possibility of processing different pipe widths. It was formed as part of a working group to develop a standard for the use of insulating materials for insulation of HVAC systems and duct systems. Gulf O Flex – Rubber Insulation NBR Rubber Insulation is the most widely used standard for determining the material properties of elastomer insulation. In addition, the smooth surface of closed cell foam is easily cleanable so the possibility of surface mold can be eliminated by cleaning surface dirt that can act as a food source for mold. Therefore, mold growth cannot occur beneath the surface of the rubber insulation. Closed cell insulation, like GulfoFlex, does not absorb water. For this reason, these materials often have a thin moisture retarder applied on the surface, but the moisture retarder is easily damaged during installation and maintenance leaving the entire insulation system susceptible to mold growth. Open cell structure insulation, like fiberglass, readily absorbs water allowing for mold and other microbial growth. Choosing closed cell insulation instead of open cell rubber insulation can make a difference. If moisture from condensation is present, water absorption into the insulation may lead to mold spore growth resulting in contaminated air and poor indoor air quality. ![]() This is due to the threat of water vapor creating condensation on AC ducts when the dew point temperature of the ambient air is higher than the operating temperature of the HVAC system. Proactive against potential threats to occupant air quality HVAC air handlers and ductwork can be a source of fungi and other microbial pollutants. In addition, fiber-free and mold-resistant materials can have a positive impact on the air that the occupants breathe. Selecting the right Rubber insulation for air handlers such as duct liners or wraps can bring multiple benefits to the HVAC system mainly recognized in its value of thermal and acoustical properties. Achieving these IAQ goals requires sifting through an assortment of specialized building products-one in particular is mechanical insulation. Perfect Rubber NBR Insulation Can Help Preserve Indoor Air Quality IAQ is up to the building owners’ commitment Indoor Air Quality (IAQ) has been a growing concern in the sustainable design and renovation of commercial buildings, with the objective for providing clearer, uncontaminated interior air for the building’s occupants. ![]()
