Custom-90’s are widely used in applications where numerous inside and outside 90-degree transitions are required.Custom-90’s, are factory-fabricated inside and outside 90-degree transition pieces coated on just the weather-facing faces.Custom-90’s are widely used in stadium tread and riser applications or other applications where numerous inside and outside 90-degree transitions are required.Custom-90’s are available when field conditions and measurements are known up front.U-90’s have a 12-inch (305mm) long leg and a 6-inch (152mm) vertical piece on each side of the elbow.Straight-run sticks are joined in the field to the U-90’s.U-90 transitions are symmetrically coated on both faces allowing them to be installed as an inside corner or as an outside corner.Watertightness through the plane change is guaranteed–leaving nothing to chance in field-fabricating inside and outside transitions.Use of U-90’s eliminates the field work needed to make plane changes making overall installation fast and efficient.Universal-90’s (or U-90’s) are factory-made 90-degree transition pieces that ensure continuity-of-seal and fire protection where expansion joints change plane.Transitions & Terminations Universal-90’s The foam provides a resilient backing to the silicone coating, making the system capable of resisting air pressure differentials caused by building climate controls as well as by wind, hurricane and tornado events.After removal from the shrink-wrap and hard board restraining packaging, it expands gradually. The material is supplied in 6.56 LF (2m) shrink-wrapped lengths (sticks).As joint movement occurs the bellows simply folds and unfolds free of tension on the bond line, and virtually free of tensile stresses in the silicone material. When compressed, a bellows is created in the coating.The material is precompressed to less than the joint size for easy insertion.This ensures, in contrast to field applied liquid sealant and backer rod installations (‘ caulk-and-backer rod‘), that no movement takes place during curing that can cause deformation or stresses in the sealant material. Silicone application and curing takes place in a temperature and humidity-controlled factory environment.The external silicone facing is factory applied to the foam at a width greater than maximum joint extension and is cured before final compression.Produced by infusing a cellular foam base material with a hydrophobic, hydrophobic-acrylic impregnation, and coating the surface with a high-performance silicone to suit the application.Details for watertight, transitions using factory-fabricated Universal and Custom transitions pieces are available from EMSEAL.Īesthetics & Versatility- Many industry standard colors, uniform bellows appearance, ability to handle variations in joint size are among other system features. Non-invasive anchoring means the system is locked to the joint faces by means of the 1) backpressure of the foam, 2) the injected silicone corner bead at the joint face to foam and silicone bellows interface.Ĭontinuity of Seal-as in all EMSEAL expansion joint systems, continuity of seal through changes in plane and direction is an essential performance differentiator. This includes embedded pins, anchors, screws, bolts or tracks, trays or rails that often damage sensitive substrates and act as a thermal bridge. Non-Invasive Anchoring-there are no hard metal-to-substrate connections in the system. This ensures watertightness is achieved at the face of the wall preventing water getting trapped against the substrates or within the joint cavity. Watertight-the low tension silicone bellows is installed just back from the wall surface.
