The present invention discloses an improved light transmitting plastic panel (100) used in buildings for providing a variable daylight either during a day or in various areas of the building. The light transmitting plastic panel (100) consists of two transparent plates (102A, 102B) and a plurality of transparent hollow cells of V-type (104A, 104B) and rhombus shaped cells (106) located in between these plates (102A, 102B). In particular, a structure of the hollow cells is a repetitive sequence of one rhombus cell (106) in between two V-type cells (104A, 104B). Further, some of the hollow cells are made opaque with a predetermined pattern. With this specific structure, the variable daylight is achieved based on a time of day. In another aspect of the invention, differential daylight is provided for different areas of the building by forming a non-continuous flow pattern of opaque hollow cells across the length of the light transmitting plastic panel (100).

Disclosed is an energy-saving hollow sheet whose spacing bars between the multiple panels are totally canceled; whose positions of screw hole have cylinders of certain thickness mounted by directly moulding, gluing, assembling, etc.; whose panels have frame at their brim; whose panels' distances and positions to each other are fixed by the above cylinders and frames with the distances between the panels controllable and the number of panel layers addable thereby, resulting in a thermal insulating performance able to reach any level; whose cancel of the spacing bars can bring a transparency same to glass curtain walls.

A scaffold board (10) of extruded thermoplastic material. The board (10) includes a substantially rectangular outer profile and a plurality of strengtheners (20). The substantially rectangular outer profile is defined by a top wall (12), a bottom wall (14) and a pair of side walls (16, 18). The plurality of strengtheners (20) each extend between an inner surface of the top wall and an inner surface of the bottom wall. Each of the strengtheners have a middle part (20c), a pair of top parts (20a, 20b), and a pair of bottom parts (20d, 20e). The middle part (20c) is oriented normally to the plane of the top wall (12) and the bottom wall (14). The pair of top parts (20a, 20b) each extend outwardly from a top of the middle part (20c) to the inner surface of the top wall (12) in substantially equal and opposite directions respectively. The pair of bottom parts (20d, 20e) each extend outwardly from a bottom of the middle part (20c) to the inner surface of the bottom wall (14) in substantially equal and opposite angles.

A multiwall sheet (30) comprising a first wall (2); a second wall (4); a plurality of ribs (8) extended between the first and second walls (2, 4); and a plurality of mid-ribs (6), wherein one mid-rib (6) extends between each two adjacent ribs (8), wherein the mid-ribs (6) extend at a mid-rib angle (18) relative to an adjoining rib (8), and wherein the mid-rib angle (18) is not 90 relative to a rib (8) to which it attaches, wherein the mid-ribs (6) attach only to adjacent ribs (8), and wherein the mid-ribs (6) do not attach to either the first or second walls (2, 4).

A device and a method allow for adhering sealing tape to open end of a multilayer sheet, usable at the production line and at the installation site. The device comprise means for applying pressure and heat onto the sealing tape and cutting blades for removing protruding edges of the sealing tape after it was adhered. The method comprise providing of a sealing tape, attaching and adhering the sealing tape to an open end of a multi-wall sheet by means of heat and/or pressure and adhesive and removal of protruding edges using cutting blades.

The invention relates to a component (1) for installing a room closing element made of hollow glass blocks (2, 3) using mortar or concrete and a suitable reinforcement. The component (1) according to the invention consists of two hollow glass blocks (2, 3), which are designed identically and preferably lie one next to the other, with an intermediate spacer (4) which seals the intermediate space between the glass blocks (2, 3) and is preferably assembled from multiple spacers (5, 5b, 5c) designed as hollow bodies that are separated from one another by intermediate films (6a, 6b) with coatings (7a, 7b). The component (1) is characterized by a comparatively large structural depth which ensures very good insulation values despite the small surface area of the glass blocks (2, 3). The structural depth also increases the geometrical moment of inertia with respect to bending, said moment of inertia allowing for large proportions of insulating mortar/concrete and components with large dimensions.

In one embodiment, a multiwall sheet comprises: non-intersecting polymer walls comprising outer layers and transverse layers. The transverse layers intersect the walls to form cells. The multiwall sheet has a non-uniform cell density. In another embodiment, a multiwall sheet can comprise: non-intersecting polymer walls comprising outer layers and a transverse layer and/or a divider. The transverse layer and/or the divider extends from one of the polymer walls to another of the polymer walls to form cells. The multiwall sheet has a non-uniform cell density. In yet another embodiment, a multiwall sheet comprises: non-intersecting polymer walls comprising outer layers and transverse layers. The transverse layers intersect the walls to form cells. The multiwall sheet has a different number of inner layers, transverse layers, and/or dividers, in different portions of the sheet. The multiwall sheets can be used, for example, in a naturally light structure.

A work-station utilizes sound absorbing, translucent enclosure panels that allows light from outside of the work-station to enter. The translucent enclosure panels have an outside panel, and intermediate panel and an inside panel of a translucent plastic sheet material that form cells for dampening sound transmission through the enclosure panels. The inside panel has a plurality of apertures to allow sound to enter and be dissipated within the internal cells. A sound masking device is configured within the work-station and projects a dampening sound into the work-station, such as along the opening to work-station to produce a masking sound curtain for sound entering the work-station.
