Floor Movement Control Joints

Why are movement joints needed.
Floor movement control joints. In other words if the concrete does crack you want to have an active role in deciding where it will crack and that it will crack in a straight line instead of randomly. Dt cover plate thermal movement floor to floor surface mount pedestrian traffic optional moisture or fire barrier. Buildings are designed to allow movement in response to various forces including thermal expansion and contraction long term shrinkage of structures as well as seismic activity in some cases. Control joints expansion joints and cold joints in concrete home structural concrete slab control joints expansion joints and cold joints in concrete without the proper type of joints in concrete it may crack in an unsightly or random manner causing damage and in a few instances result in trip hazards.
Why do rooms with more sunlight need more movement joints. Butt joint cover plate thermal movement floor to floor surface mount pedestrian traffic optional moisture or fire barrier. Architectural aluminum anti slip system. Control joints are planned cracks which allow for movements caused by temperature changes and drying shrinkage.
Covers are used as expansion joint gap covers for areas that experience movement within structures for example in construction joints in concrete slabs. Floor expansion joint covers for both thermal and seismic applications our floor to floor and floor to wall floor expansion joint systems allow 6 way movement or 4 way movement whilst the surface fixed products generally cover 2 directional movement. Not the entire floor if elsewhere the floor is an even temperature.
