Fiberglass Insulation Supports Better Learning

Article content provided by Johns Manville

Creating productive learning environments starts with effective HVAC design. Fiberglass duct liner and duct board insulation can help schools maintain quieter, more comfortable and energy-efficient spaces by reducing HVAC noise and improving thermal performance. Studies show that background noise can impact student comprehension, making sound control an important consideration in educational facilities. Fiberglass insulation products help absorb and reduce HVAC-generated noise, supporting a better classroom experience.

Fiberglass insulation also helps prevent condensation on ductwork, reducing the risk of mold growth, corrosion, and system deterioration. When properly installed and maintained, fiberglass duct products do not support microbial growth, contributing to healthier indoor air quality. Coated fiberglass insulation products offer additional protection. Johns Manville Linacoustic® RC and RC-IG products have our proprietary Permacote® coating, as does our Spiracoustic Plus® round duct liner system. Formulated with an immobilized, EPA-registered protective agent, Permacote provides a durable surface and added product protection against microbial growth.

In addition, insulated duct systems help deliver conditioned air at the intended temperature, reducing HVAC workload, lowering energy consumption and extending equipment life. For school districts facing budget constraints, fiberglass insulation offers a cost-effective solution that supports occupant comfort, operational efficiency and long-term value. Safe, rigorously tested and widely accepted throughout the industry, fiberglass remains a trusted choice for HVAC insulation in educational facilities.
