Johns Manville: Vent Chutes

At Johns Manville, we are committed to helping you create more comfortable, healthier, and energy efficient indoor environments. That’s why we revolutionized the building insulation industry by pioneering the development of Formaldehyde-free™ fibreglass building insulation over a decade ago. JM Formaldehyde-free insulation provides excellent thermal and acoustical performance. 


Vent chutes allow installation of attic floor insulation close to the soffit, enabling unobstructed air passage between the soffit vents and the attic without clogging the soffit attic ventilation ports with insulation. Rigid foam channel that creates a ventilation space between the roof deck and insulation to relieve heat and moisture buildup in the attic.
