Abstract: A method of using liner-like cores or core assemblies for creating in-ground concrete spas or swim pools. For larger projects, that is for enlarged scale spas or swim pools, the inventive liner-like core comprises an assembly of sections. The cores or core assemblies are re-usable at least for several projects if reasonably maintained and cleaned. The core assembly comprises two long walls and two short wall defining the perimeter around a split level bottom with a shallow end, a deep end, and an intermediate transition slope. The liner-like core is constructed from a suitable rigid material like fiberglass for stiffening purposes and is an assembly of sections and also comprises: leveling blocks, transverse support beams, and hangers that attach to the walls of the core assembly and stiffens the long walls against being warped inward during the concrete pour.

Abstract: A method of manufacturing a hollow core door is disclosed, as well as a corresponding hollow core door. The method includes the steps of providing a solid flat door skin, moisturizing the flat skin, applying a conditioning resin thereto, pre-heating the flat door skin, and thereafter pressing the flat door skin between a pair of heated platens in a press in order to reform the flat skin into a molded skin including a plurality of panels defined therein. The press continuously closes in order to reform the flat skin into the molded skin, with the rate of press closure being a function of the determined hardness of the flat skin to be reformed. The resulting door skins have an improved bond strength, and are efficiently manufactured.

Abstract: A method and system is provided for insulating piping installed in an exterior wall in a manner that protects the piping from freezing. Generally, the system includes an insulation block that has an interior side, an exterior side and a slot formed therein for receiving a pipe to be insulated adjacent the interior side, wherein the block is dimensioned particularly for installation into a building wall cavity. When installed, the block insures that the piping is positioned immediately adjacent the back surface of the interior sheathing material. The insulation block reliably provides a thickness of insulation material behind the piping such that the insulation material is positioned between the piping and the exterior wall surface while also maintaining the piping in contact with the rear surface of the interior wall sheathing to facilitate heat transfer from the interior of the building and into the piping.
