This is often an intriguing solution, and thanks for contemplating as a result of ways we can lessen the usage of spray foam plastics in roof insulation. Supplied the weight on the insulation which has to go into this Area, have you been able to validate, such as by fiber digital camera inspection, that the gaps above the best membrane and underneath The underside just one usually are not acquiring blocked from the insulation causing the membranes to bulge out? I might genuinely wish to check here see some photos if so.
Scorching air rises and leaves the attic, where by the process might be facilitated due to the presence of holes, cracks and ventilation challenges for example missing consumption vents and exhaust features.
