Dynatrol® II was designed for use in expansion and control joints in precast panels, tilt walls and curtain walls; bedding panels, coping joints, window and door perimeters, glazing, traffic, acoustical and fire stopping applications. Its wide color range and low modulus make it highly effective in exterior insulated finish systems (EIFS).
Control joints are designed to safely absorb the temperature-induced expansion and contraction of construction materials, to absorb vibration, to hold parts together, or to allow movement due to ground settlement or earthquakes. Dynatrol® II will withstand structural movement of 50% in extension and 50% in compression without adhesive or cohesive failure in properly designed joints.
Joint Backing: Backer rod controls the depth of the sealant and allows it to be applied under pressure. Closed-cell polyethylene or bi-cellular polyolefin foam is recommended. Use a size that will compress 25% when inserted into the joint.
