Abstract: A high-performance door system is provided. The door system comprising a door leaf having a framework which includes first and second stiles spaced apart from each other, a first rail joining a first end of the first stile with a first end of the second stile, and a second rail joining a second end of the first stile with a second end of the second stile. The first rail is provided with a groove, and each one of the stiles comprises an inner channel, each inner channel being in fluid communication with the groove. The door leaf further comprises a housing defining a hollow space which is then injected with filler material so as to fill the hollow space and the groove, thereby spreading to each one of the inner channels, thus sealing interstices between the rail and stiles.

Abstract: Disclosed is an economical and effective way of producing a double sided wall using facing panels having a face surface and a back surface with a retaining structure. The facing panels are stacked in a back-to-back arrangement into a pair of first and second wall components connected by separate articulated connectors. The articulated connectors each have a first base connector that fits into a respective retaining groove in the first wall component and a second base connector that fits into a respective retaining groove of the second wall component. The first and second base connectors are connected to each other by a link that forms a first pivot joint at the first base connector and a second pivot joint at the second base connector.

Abstract: Disclosed is an economical and effective way of producing a modular retaining wall for a material to be retained, using only blocks which in and of themselves are of insufficient thickness to function as retaining wall blocks. The modular wall includes backer blocks and facing blocks which are connected by separate connectors in a back to back, spaced apart arrangement, thereby forming a hollow retaining wall. The hollow wall is filled with loose filler material to increase the mass and retaining capacity of the wall. None of the wall components is embedded in the material to be retained. Further disclosed are wall components and a wall kit for a modular retaining wall. A double sided decorative wall is also disclosed. The modular wall system allows for the construction of retaining walls and freestanding, double sided, decorative walls forming both straight and curved walls.

Abstract: A stackable concrete wall block is disclosed having a body with an irregular front portion and a prism shaped rear portion, the irregular front portion has a three dimensional surface structure embossed in the front face providing the appearance of natural stone and the regular rear portion facilitating stacking of like blocks. The rear portion has parallel sidewalls perpendicular to a rear wall, which are more easily manufactured by dry casting than tapered sidewalls. A lip protrudes from at least one of the sidewalls of the rear portion and is coplanar with the front face for spacing the body of the block from that of a like block placed adjacent thereto. The lateral lip generates spacing between adjacent blocks at a back terminal edge, thereby allowing the assembly of curved walls. The irregular front face extends over the lip so that the front face is continuous over the lip.

Abstract: Disclosed is an economical and effective way of producing a double sided wall having a corner or closed end using facing panels having a face surface and a back surface with a retaining structure. The facing panels are stacked in a back-to-back arrangement into a pair of first and second wall components bridged by separate connectors. An end wall component forming an end or corner of the wall includes facing panels stacked to extend across the intermediate space.

The connecting members can be in individual connectors, or a combination of connectors for linking multiple facing panels or linking facing panels at corners or curves in the wall. The connectors can be of different length to enable the construction of decorative walls of different thickness.

Abstract: An artificial stone is disclosed for use in creating a covering for a supporting surface. The artificial stone includes a body for placement on the supporting surface, which is shaped for mating engagement with like stones with intermediate perimeter joints to produce a continuous surface covering. The stone has a facing surface on the body, which facing surface has a contour defining a surface area and is subdivided by at least one simulated joint into a major surface portion and at least one minor surface portion. The major surface portion is free of simulated joints and extends over at least about 60% of the total surface of the facing surface. The stone further includes at least one perimeter recess in the body for generating a gap between the stone and another like stone in mating engagement therewith, which gap is wider than adjacent the adjoining perimeter joint.
