Additional Characteristics
- Size of masonry joint is by ½ when T-Cap is interposed in a joint between sealants.
- T-Caps remain flexible and are paintable.
- T-Cap will not tear nor shear and resists corrosion.
- T-Cap covers the sealant, thereby prolonging life and preventing margin checking.
- T-Cap is not a conductor of heat & cold; it resists mold attack on covered sealant in high humidity areas.
- Stress to copings atop parapets, as well as, right angle junctions of two walls, are buffered by the T-cap.
- Other properties of T-Cap are, it is low in tensile strength, hardness, elastic modulus, and creep strength. Because of these, and the other characteristics listed above, after a building movement, the low creep strength causes the lead to creep into new the configuration. Temperature change accelerates this creep movement. The low elastic modulus allows this process to continue indefinitely within the joints design limits. Other metals would retain their original shape and permit moisture into the joint.
