Cheapest option: 15 lb Felt Paper at $159.00Tyvek HomeWrap is the most popular synthetic house wrap and offers excellent air and water resistance. Tyvek DrainWrap adds a drainage channel for walls prone to bulk water. Felt paper (15 lb or 30 lb) is a traditional, code-compliant option at a lower cost per roll but requires more rolls due to smaller coverage. All totals above include cap nails and seam tape.
