Natural wood sandwiched engineered flooring utilizes all natural wood as the raw material which is made into several components which are combined to make this product. The components are a single or multilayer top veneer bottom or base layer and a middle layer. The four sides of the natural wood sandwiched engineered flooring strip consist of either a tongue and a groove or an interlocking system. The middle layer consists of two parallel solid wood strips, and located perpendicular to and between the parallel solid wood strips are small pieces of soft wood, which are glued together. The small soft wood pieces can be of fast growing soft wood, and as such saves treasured hardwood lumber. The production cost of the raw material is much lower than other types of engineered flooring. Further, an enhanced stabilization of the hardwood flooring is provided which is more suitable for radiant heat. |

The method of this invention adheres a low emissivity radiant barrier material to an underlying lignocellulosic substrate within the primary manufacturing operation of the underlying lignocellulosic substrate. Thus, a radiant barrier covered substrate is formed by integrally joining the radiant barrier covering to a mat of lignocellulosic material during consolidation thereof with a first adhesive bonding material to form an underlying substrate. The integral joining operation can, for example, be accomplished by bonding the radiant barrier covering to a lignocellulosic mat in a product formation press. This is typically accomplished using a second adhesive bonding material for adhesion of the radiant barrier material to the lignocellulosic mat, and a first adhesive bonding material for consolidating the lignocellulosic mat to form a lignocellulosic substrate. More specifically, this invention is directed to a method whereby a low emissivity radiant barrier material is joined in situ to a mat of lignocellulosic particles using a second adhesive material, during the consolidation of the lignocellulosic particles and a first adhesive bonding material to form an underlying substrate, an integral laminated radiant barrier covered lignocellulosic product being produced. |

Wood can be hot-pressed into various composites using as adhesive subdivided plant foliage. Considerable bond strength is achieved, the bonds having water resistance adequate for many uses. The foliage is the primary adhesive i.e., is greater than 95% wt. of the active adhesive components present. The foliage can be used either in the form of a powder or as a dispersion in an aqueous liquid carrier. The foliage-wood system is hot-pressed to achieve the desired bonding, the pressing temperature being above the softening temperature of the foliage. The softening temperature of the foliage varies depending on the moisture content. The foliage proportions in the composite can range from about 1% to about 60% by wt. or more in some cases. Increased bond strengths have been achieved using formaldehyde crosslinking agents or alkaline additives. |

Absorptive substrates, such as asbestos cement, concrete plaster work, can be impregnated to lock the pores and to consolidate the substrate, especially old and weathered plaster work, with aqueous plastics dispersions, if dispersions are used which have an average particle size of about 0.02 to at most 0.1.mu.m, and preferably from 0.036 to 0.080.mu.m. As opposed to conventional dispersions with larger particle sizes, the penetration of dispersions according to the invention reaches the same values as that of the solvent-based impregnating and priming compositions hitherto used. Aqueous dispersions are easier to handle and permit relatively high solids contents at a moderate viscosity. |
