Surface elements comprising a decorative upper layer and a supporting core are disclosed. In such surface elements the decorative upper layer can comprise a digitally applied wood grain pattern made up of at least four colors, said pattern being applied to an underlying white ground coating provided on said supporting core, said pattern comprising at least one of visually simulated knots, cracks, flaws and grain. In such surface elements the decorative upper layer can further comprise an at least partly translucent wear layer arranged over said pattern, said wear layer consisting of a cured substance comprising silicon oxide. In such surface elements the decorative upper layer can further be provided with a surface structure increasing the realism of said wood grain pattern, being directed in accordance with the direction of said pattern and being in the form of narrow elongated recesses simulating the pores of wood.

The present application is directed to Large Enclosed Secure Greenhouse Structure Atrium/Hybrid Greenhouse Buildings that have the appearance of a new modern industrial building that will provide a complete agricultural growing facility with an office, maintenance and dry storage spaces. The roof and walls of the greenhouse area have a continuous sealed chamber through transparent open web joists and girders, with controlled sunlight transmission along with heat and cold circulation. More particularly, the Atrium/Hybrid Greenhouse Building provided is constructed using a number of joist and girder systems configured to support transparent reinforced roof, wall and ceiling panels, assembled in a way that provides maximum daylight transmission and significant insulating properties, enabling the Atrium/Hybrid Greenhouse Building to be an effective and economical grow-house in harsh environments and in areas with snowfall or widely varying temperature ranges. The air in the building will be filtered through a system capable of filtering out a variety of particle matter including pesticides and herbicides with clean rooms between separate growing areas and exit areas. The Atrium/Hybrid Greenhouse Building provided is constructed using a number of joist and girder systems configured to support transparent reinforced roof, wall and ceiling panels.
