Johns Manville fiberglass batt insulation is one of Wilson’s favorites because it’s composed of recycled materials and contains no formaldehyde. Instead, the product uses an acrylic binder that doesn’t off-gas. It’s “better for the air,” Wilson says. Its environmental impact is also lessened because it uses fewer “virgin materials,” he adds.
