A Z-shaped attachment element for use in building construction is disclosed. The Z-shaped attachment element is made from a single piece of sheet metal that is first cut and then bent to form the Z-shaped cross-sectional profile. The Z-shaped attachment element comprises: an elongated upper flange; an elongated lower flange, wherein the upper and lower flanges are spaced apart and substantially parallel to each other; an elongated middle web section between, and connected to, the upper and lower flanges along respective upper and lower lengthwise bends (wherein the middle web section is diagonal in relation to the position of the upper and lower flanges, thereby defining a generally Z-shaped cross-sectional profile); and a plurality of notches formed along the lower lengthwise bend and into the lower flange and the adjoining middle web section, but not into the upper bend or the upper flange, of the Z-shaped sheet metal attachment element.

Portable and removable wall modules for residential living space are disclosed. The modules create a sound dampening or near-soundproof division of the living space. The modules comprise one or more u-channel bars that attach to the ceiling and wall and one or more adjustable baseboards that sit on the floor. The adjustable active baseboards each comprise a spring-loaded platform that pushes the wall panels upward against the top interior of the u-channel bars and ceiling to create a vertically-sealed division of the living space. The product can be used for all ages and uses; splitting a room for two children, young adults in dormitories or apartments, creating a hard wall that looks good. It provides costs savings avoiding having to move and lease larger spaces, especially in high costs and dense urban housing markets. The product is easy to install, remove and is reusable. It can be relocated when moving from one dwelling to another and it adjusts to differing ceiling heights and room sizes of dwellings.

There is disclosed a relocatable internal wall panel, kit and system for a room having a floor and ceiling. The wall panel comprises a first wall portion and a second wall portion having opposed planar surfaces to define a void. The first wall portion is at least partly received within the void defined within the second wall portion in a retracted position and reversibly extendable therefrom such that in the extended position the upper edge of the first wall portion bears against the ceiling of the room.

A system for the partition of a space that has a ceiling includes at least one partition wall that partitions the space and has at least one planar element and a system connecting it to the ceiling. Such system and the upper peripheral edge of the planar element include male and female elements. The connecting system further includes at least one elastomeric element interposed between the female and the male elements, which deforms upon the coupling of the male and female elements and frictionally acts against them to prevent the planar element from falling down by gravity, without the need for additional support in the lower part of the planar element.
