An insulation product may include an insulation material. The insulation material may include at least one material selected from the group consisting of nonwoven insulation, aerogel insulation, mineral insulation, and foam insulation. The insulation material may include a first end and a second end positioned opposite the first end. The first end may include a protrusion. At least a portion of the protrusion may widen in a direction opposite the second end. The second end may define a cutout that substantially matches a size and shape of the protrusion. The cutout and the protrusion may be aligned with one another along a length of the insulation material.

In some embodiments, a building block includes alignment elements that interlink with a similar block with a positional offset. For example, the positional offset may be linear and/or rotational. For example, the second cinder block may be rotated with respect to the first block on which it is supports. Optionally, protrusions from the top of the block are positioned to interlink to the vertical slots at a fixed offset between the blocks. Optionally, the protrusions are formed by channels on a mold and/or a mold head. In some embodiments, a structure may be built stacked blocks. Optionally, a decorative face is configured to form a continuous decorated surface across offset blocks. In some embodiments a building block includes a calibration feature. For example, the block may include a ridge on the top of the block that may be shaved and/or ground to adjust the height of the block.

Building panels provided with a mechanical locking system including a tongue, at an edge of a first panel, cooperating with a tongue groove, at an edge of an adjacent second panel, for vertical locking of the building panels. The edge of the first panel is provided with a displacement groove, which is downwardly open, and includes an inner wall, an outer wall, and an upper wall. The tongue is formed out of the edge of the first panel. A resilient and displaceable and part of the tongue is displaceable into the displacement groove.

The present invention relates to a building construction using bulge notch connectors located within a wall cavity at the top and bottom end of metal framing members as well as through the holes in the metal forming members. The spacing-bracing members connecting the metal framing members have bulges, bulge notches, lips and lip notches in the spacing-bracing members and the holes securing the spacing bracing members have notches to secure framing members together. The holes can have holes notches or hole bulges to connect the bulges and bulge notches to connect metal framing components together. The longitudinal ends of the spacing-bracing members can have hook tongues with adjoining members having receiver holes for the tongue portion to fit into.

A floor panel has a rectangular and oblong shape, and includes a substrate and a top layer provided on the substrate and forming a decorative side of the floor panel. The top layer is composed of a print provided on a carrier sheet and a transparent thermoplastic layer situated above the print. The substrate has a thickness from 2 to 10 millimeter and forms at least half of the thickness of the floor panel. The substrate is a polyurethane-based substrate and the transparent thermoplastic layer is polyurethane-based. The floor panel has a length of more than 1.1 meters and has a plurality of reinforcing layers situated outside the center line of the substrate. A reinforcing layer may be provided in combination with the substrate and the top layer.

Disclosed is a thin-film radio frequency absorber material that is mass-produced by a high-speed manufacturing method of printing a highly controlled pattern of conductive ink squares onto a thin roll film, resulting in a lightweight low-cost radio frequency absorber component that is flexible for use in multiple novel configurations. The roll film material and printed squares are each easily adjustable to a specific size and thickness within the manufacturing process to coincide with control and protections related to variable specific radio and radar wave frequencies. Further integration into the three-layered thin-profile radio frequency energy absorber and reflector assembly provides control and protection properties related to radio and radar frequency, infrared, electromagnetic pulse, electromagnetic interference, and thermal insulation values in structural building panels utilized in lightweight structures such as the foldable transportable structure or other types of building and protection assemblies.

Floor panels which are provided with a mechanical locking system including an extruded flexible tongue in a sidewardly open groove which during a vertical folding motion is bent horizontally. A tongue adapted for being received in a sidewardly open groove of a floor panel, wherein the tongue, which is an elongated extruded section, when received in the groove is bendable in a plane substantially parallel with a front face of the floor panel, such that the tongue is at least partially resiliently displaceable inside said sidewardly open groove in said plane during locking of the floor panel with another floor panel and wherein a vertical protrusion, serving as a friction connection between the tongue and the groove, is arranged at an upper or lower part of the tongue, wherein the tongue has a length in the longitudinal direction of the tongue and a total width perpendicular to the length, and the total width varies in the longitudinal direction of the tongue.
