Devices and methods for compressing thermal insulation material into blocks of insulation are disclosed which include a support surface for the compressed blocks of insulation, a compression device with a compression surface, and a feeding device for feeding thermal insulation material. By adapting the compression device for reciprocal movement between a first position, wherein the feeding device is allowed to feed thermal insulation material to a position on the support surface, and a second position, wherein, during movement from the first position to the second position of the compression device, thermal insulation material fed by the feeding device is compressed, highly compressed blocks of thermal insulation material are obtained that are suitable for use with known shredding devices.

Environmentally responsible insulating construction blocks and structures constructed primarily of recycled materials are disclosed. The environmentally friendly construction blocks and structures comprise shredded rubber tire pieces coated with silica fume, slag cement and cement, which are then mixed with water and formed in a mold. A layer of grout or a fireproof material may be disposed on one side of the environmentally responsible insulating construction block. The environmentally responsible insulating construction blocks can be used in place of wood blocking for roof assembly applications such as installation of a drip edge or wall coping; or in expansion joints. The environmentally responsible insulating construction blocks provide high insulation as well as strength for applications such as green roofing, wall construction and green roofing decks. Environmentally friendly structures can be built by pouring the coated shredded rubber tire pieces into molds to form walls, and then to pour a layer of the coated shredded rubber tire pieces as a roof deck, thereby creating a self-supporting structure in a monolithic pour.

Lightweight masonry hollow bricks of a substantially rectangular cuboid shape having central cavities and side indentations. A concrete composition of the masonry hollow bricks includes cement, water, sand, a coarse aggregate, and an insulating material, e.g. perlite, polyethylene, crumb rubber. The developed masonry hollow bricks met the ASTM requirements for non-load bearing masonry bricks in addition to satisfying the ASTM standard as being lightweight masonry bricks.

The invention relates to a method for producing flexible or elastic wood fiber insulating material products, having the following steps: -providing wood fibers which have been produced in a refiner. -providing multicomponent fibers with an inner and an outer component, said outer component melting or fusing at a melting temperature at which the inner component does not melt or fuse or has not yet melted or fused. -providing a mixture of wood fibers and multicomponent fibers. -heating the mixture to a temperature at which the outer component melts or fuses, andconnecting the multicomponent fibers together and to the wood fibers while cooling the mixture, wherein hardwood fiber bundles, in particular beechwood fiber bundles, are used as the wood fibers, and biodegradable multicomponent fibers are used as the multicomponent fibers.

Self-standing, thermally-insulating, noise-insulating, seismically-insulating, water-insulating, electromagnetic-insulating superstructure, whose overall internal volume is filled with rigid and lightweight granules, in which the dwelling rooms are immersed. The lightweight granules are spherical, porous or hollow, they have no binder and are scattered. A gas-tight skin clads all the outer surface of the superstructure's shell and the walls of the dwelling quarters. Gas-tight bay-frames of conical outer shape are embedded in the openings and bays. The entire volume, made up of the scattered granules, the plates, the bay-frames and the gas-tight skin, is under gas-vacuum. This gas-vacuum is lifetime-controlled by a vacuum pump which is installed in situ. The outer casing and the inner walls are braced by the volume of granules stiffened by atmospheric pressure. A plurality of ion-polarized layers, vaporized on overlay metallized polymer vacuum sheets, are inserted between the rigid plates and the gasproof skin.

A method of making a structural lightweight and thermal insulating concrete is described. The concrete has a coarse aggregate partly replaced by recycled plastic pieces. This enables the concrete to maintain a high compressive strength, low thermal conductivity, and low weight, while providing a use for waste plastic. The waste plastic pieces may comprise polyethylene in the form of flakes, fibers, or granules. Due to its low unit weight, adequate compressive strength and high thermal resistance the developed concrete can be used as a structural lightweight and thermal insulating concrete. The use of this concrete leads to economic and environmental benefits.

Breakthrough resistant drywall structure, classified at least for resistance class 2 according to DIN EN 1627 from September 2011, having at least two studs arranged to form a drywall substructure, each stud including a base portion and at least one flange portion, the drywall structure further having a plurality of building panels attached to the at least one flange portion, the drywall structure 1 further including a filling material, wherein the filling material comprises fibers.

The invention relates to a construction apparatus with a first and second construction part each including a receiving portion. An interlocking means is included, adapt to be received in the receiving portions of the first and second construction parts when put together to maintain the first panel and second panel together. The invention relates to a construction apparatus made of bamboo. The invention also relates to methods of use of the invention. The invention also relates to an engineered bamboo panel.

A thermal insulation material is made of a plurality of insulating components. The plurality of insulating components includes a first insulating component made of wood shavings. The plurality of insulating components includes a second insulating component made of cellulose fibers, wherein the cellulose fibers are arranged in voids formed between the wood shavings. The cellulose fibers of the second insulating component are produced from decor paper or sanitary paper.
