Testing has shown NovaSeal Roof Underlayments to be as much as 20 times stronger than roofing felt at 1/10 the weight, the maker says. The anti-slip synthetic material features an engineered coating to create a durable surface with better traction. For increased productivity, a single roll of NovaSeal provides five times more coverage than standard felts. The material can be left exposed for up to 12 months and offers tear and puncture resistance. IPG | 800.474.8273 | itape.com
