The Durovent has a perforation down the middle when split the product can be used in 16 in on center applications.

What Customers Are Saying

Customers praise this product for its affordability, simple installation, and effective ventilation between roof rafters. Most appreciate how easily it staples, cuts, and splits to fit standard rafter spacing without specialized tools, with many noting it creates proper air gaps for heat and moisture venting. Reviewers consistently highlight excellent value compared to pricier alternatives. However, some express frustration with its thin, brittle foam construction, reporting it snags or cracks during handling. Despite fragility concerns, most customers consider it a worthwhile, budget-friendly solution that performs its intended function reliably.
