Unroll Tamlyn ProSelect™ Commercial Wrap with filaments facing to the exterior and fasten to sheathing with cap fasteners 2. Fasteners should provide a minimum ½” penetration into the nail base and be spaced approximately 12 – 18 inches apart along the horizontal and vertical laps. Fasten every 3 sq. ft. elsewhere. 3. Tamlyn ProSelect™ Commercial Wrap should be installed shingle lap fashion (i.e. begin installation at the base of the wall assembly). Extend housewrap a minimum 2” over sill plate. 4. Overlap all horizontal and vertical seams at least 6 inches and corners by 12 inches. 5. Be sure that the housewrap installation and flashing provide for positive drainage to the exterior of the assembly. 6. Do not allow the housewrap to be exposed to sunlight in excess of 120 days. Recommended coverage within 30 days. Midtown West Studio M Architecture and Planning Carmel, IN November 10, 2017 (ASI-002, 02.05.2018) 07 25 00 - 4 7.
