Abstract

A temporary containment barrier for use during construction or renovation includes a plastic film configured to shrink when heated. The film may have a melting point between 60 and 140 degrees celsius. The film may be configured to shrink in at least one direction by 20% to 60% if heated. At least a portion of the film may be uniaxially oriented. At least a portion of the film may be biaxially oriented. The film may have a thickness between 30 microns and 300 microns. The film may include at least one flame retardant modifier. In the event of a fire, the film may quickly dissipate and subside before the fire sprinkler is activated and thus will not impede the operation of the sprinkler.

Description

Temporary containment barrier and related methods Cross Reference to Related Applications The present application claims priority from U.S. provisional application No. 63/590,065 filed on day 13, 10, 2023, the entire contents of which are incorporated herein by reference. Technical Field The present disclosure relates generally to temporary protective barriers that may be installed under ceilings to prevent and control debris from construction operations performed on ceilings or roofs of buildings. SUMMARY The following paragraphs do not acknowledge that anything discussed therein is prior art or part of the knowledge of one of ordinary skill in the art. Plastic films may be used during construction or renovation of a building, which are located below the ceiling within the building and optionally below the fire sprinkler system. Such barrier films are intended to catch dirt, dust and debris from construction operations on the ceilings or roofs of buildings, which may interfere with equipment, inventory, procedures, staff, customers or the general public. The membrane may be mounted in a horizontal arrangement, separating the roof panel/ceiling from the underlying area. The membrane may also be mounted in a vertical arrangement as a "shroud" separating two adjacent spaces. For example, grocery stores, food manufacturing/packaging facilities, sanitary facilities, and highly sensitive IT sites may be beneficiaries of such devices. The ceiling enclosure barrier may enable large businesses to remain open and safely conduct daily business while conducting ceiling and/or roof projects. The lifetime of the system is typically several months until the construction operation is completed, after which the film and the debris captured in the film can be removed from the building and disposed of. The ceiling enclosure barrier can interfere with the function of the building sprinkler system. Some existing systems rely on water reactive or fused seams that join portions of the barrier to fail, releasing the barrier and allowing the fire sprinkler system to access the fire area below. By relying on the seam to open a passageway after contact with water or heat in a particular area of the seam, there can be a significant delay during activation of the spray system. These systems also tend to be expensive and may require site-specific prefabrication/prefabrication depending on the location or building layout of the fire sprinkler, which may result in long lead times, difficult installation and response delays. The following is intended to introduce the reader to the detailed description below, and is not intended to define or limit the claimed subject matter. The present invention relates to a temporary containment barrier comprising a plastic film, and the film is configured to shrink when heated. The film may have a melting point between 60 and 140 degrees celsius. The film may have a melting point between 70 and 120 degrees celsius.
