Berry Plastics 628 Barricade Seam & Seal Construction Tape [Discontinued]
Berry Plastics 628 has been discontinued. Please see Shurtape HW-300 as an alternative housewrap sheathing tape.
Berry Plastics 628 Barricade Seam & Seal Construction Tape is applied over the seams of installed housewrap to contribute towards a secondary line of defense against exterior moisture penetration of the wall envelope. It helps to maximize energy efficiency by sealing the gaps, cracks and crevices where air can easily penetrate the home and ultimately affect your heating and cooling costs. Berry Seam & Seal is recommended for:
- Door flanges and frames.
- Sealing holes and gaps in the exterior wall around faucets, dryer vents, electrical outlets and more.
- Exterior wall sheathing joints.
- Housewrap (Tyvek) seams and overlaps.
- Patching job site damage caused to fragile wall sheathings such as foam and fiberboard.
- Window flanges and frames.
Berry Barricade Seam & Seal is a thin, strong, white polypropylene film coated with a cold weather acrylic adhesive system. It is specially formulated to have excellent performance characteristics at sub-freezing
temperatures along with good quick stickability for ease in applying. Used to repair rips, punctures or tears in the
sheathing or housewrap material. This tape can be applied to corners, joints, sill plates, etc., to improve air tightness. Berry Plastics Seam and Seal Construction Tape by itself, should not be used as a flashing material around windows and doors when it is not used in conjunction with an approved flashing material (one that meets or exceeds Fed. Spec. UU-B-790a Grade A), may compromise the wall system's ability to effectively resist exterior moisture penetration.

Please note that tape rolls are NOT guaranteed to be splice-free. Tape rolls are typically cut to standard tape industry metric-cut sizes - or approx 5% narrower than the nominal size (i.e. 24mm per 1-inch of nominal width ordered).
hot melt rubber (synthetic)
Offers the widest range of application flexibility available. Exhibits excellent processing performance whether manually or automatically applied. Has superior tensile strength, adhesion properties and holding force which ensures consistent, reliable seals. Hot melt adhesive will bond faster to a surface which is referred to as quick-grab or quick-stick. It typically has higher tack (will feel stickier to the touch), but is also softer. It has lower heat resistance, shear resistance, and sometimes UV resistance than an acrylic adhesive. NOTE: it is called hot melt because the adhesive is applied hot by the manufacturer and then hardens as it cools (you do not need to apply heat to the tape yourself).
Properties are similar to that of hot melt rubber, but natural rubber often holds where other adhesives won't (recycled fibers, dust, cold, heat and heavy loads). It provides good overall adhesion and moisture resistance.
Offer excellent performance, especially for applications in temperatures less than 40°F and greater then 120°F. It provides excellent clarity, has high shear strength, is usually more permanent/durable even when exposed to moisture, and it ages well over extended periods in fluorescent and sunlight. Since it remains clear for the life of the application and does not yellow over time it is ideal for applications such as sealing white cartons. While it has good initial adhesion it does take 24-48 hours to cure and to achieve its maximum bond strength (has gradual adhesion buildup). Another difference between hot melt rubber and acrylic adhesive is if you fold tape over making the two adhesive sides touch the acrylic adhesive will remain attached to the carrier (e.g. paper, film) while a hot melt adhesive will stick to itself and pull off of the carrier. It is the best choice for clarity, UV resistance and aging characteristics.
Is great for extreme temperature applications since silicone adhesive can work in continuous operating temperatures from -100°F to 500°F. They also exhibit good chemical resistance, retain electrical properties, and remove cleanly with little or no residue.
Zinc oxide based adhesive formula is a skin-friendly adhesive which is commonly used on sports medicine tapes.
Thickness, AKA caliper or gauge, refers to the distance from one surface of a tape backing, or adhesive, to the other.
1 mil = 1/1000 of an inch
Examples: 1/16 inch = 62.5 mils; 1/32 inch = 31.25 mils
