An interlock connector interlocks building blocks that are assembled so as to provide a wall structure. The building blocks have respective front surfaces for defining a front façade of the wall structure and respective rear surfaces with at least one respective horizontal groove. The interlock connector comprises first and second bodies. The first body is inserted in the rear surface horizontal groove of a first building block. The second body is inserted in the rear surface horizontal groove of a second building block adjacent the first building block. Insertion of the first and second bodies in the respective rear surface horizontal grooves of the first and second building blocks provides for interlocking the first and second building blocks.

An insulating system for retrofitting the roof and/or walls of a building. The retrofit system includes a first layer of insulating material extending transverse to the purlins, girts and chords and atop the existing roof or wall structure as well as a plurality of longitudinally extending bridge members each with an upper and a lower surface. The system also includes a plurality of orthogonally extending spacer members that compresses the first layer of insulating material proximate to the spacer members and allowing an otherwise uncompressed first insulation layer to span between the spacer members. The system further includes a second layer of insulation extending across the upper surface of the bridge members wherein a plurality of panel clips each with a panel clip tab are disposed atop the second layer of insulation and are fastened to the bridge member and the clip tabs engage with the lateral edges of the roof or wall panels in the formation of a water resistant seam.

A floor may include a substrate having a top side and a bottom side. A top layer may be provided on the substrate. The top layer may consist of a printed thermoplastic film and a thermoplastic transparent or translucent layer provided on the printed thermoplastic film. The top layer may be directly adhered to the substrate by heat welding the printed thermoplastic film and the top side of the substrate, in the absence of a glue layer. The substrate may be a synthetic material board including a filler. The substrate at least at two opposite edges may include coupling means provided in the synthetic material board. The thermoplastic transparent or translucent layer may be provided with a structure.

A connector block is provided, for joining boards of a garden bed or of a planter box. The connector block has a top face, a bottom face and four lateral faces, each face being provided with a slot for receiving the extremity of a board. The connector block is also provided with a through hole extending from the top face to the bottom face for receiving a grounding rod bar.

A construction block unit includes a construction block including a bottom plate having a rectangular shape, sidewalls attached to each side of the bottom plate via hinges, wherein the sidewalls rotate on the hinges from a position planar with the bottom plate for storage to a position perpendicular to the bottom plate to form a receptacle configured to receive and contain a weight, and a pair of interlocking portions, each at opposite sides of the construction block to fasten the sidewalls in the position perpendicular to the bottom plate. Each of the pair of interlocking portions is shaped to receive a corresponding interlocking portion of a second construction block by vertically sliding the corresponding interlocking portion into the interlocking portion.

Polyurethane composites and methods of preparing polyurethane composites are described herein. The polyurethane composite can comprise (a) a polyurethane formed by the reaction of (i) one or more isocyanates selected from the group consisting of diisocyanates, polyisocyanates, and mixtures thereof, and (ii) one or more polyols; (b) fly ash comprising 50% or greater by weight, fly ash particles having a particle size of from 0.2 micron to 100 microns; and (c) a coarse filler material comprising 80% or greater by weight, filler particles having a particle size of from greater than 250 microns to 10 mm. The coarse filler material can be present in the composite in an amount of from 1% to 40% by weight, based on the total weight of the composite. The weight ratio of the fly ash to the coarse filler material can be from 9:1 to 200:1.
