A sliding window including: a window frame that is fixed in a wall and is provided with at least one rail therein; and a sash that is provided with a window wheel unit in contact with the rail of the window frame, and is provided with a diverting unit for diverting wheels of the window wheel unit. Due to the diverting unit, the window wheel unit can bring the sash into close contact with or can release the sash from the window frame, so the sliding window can remove a narrow gap from between the sash and the window frame. Accordingly, not only airtight, watertight, insulating, and soundproof performance can be improved, but also wind pressure resistance performance can be improved.

Disclosed is a vacuum insulation panel having excellent thermal insulation and cold retention performance using conventional glass fibers. The vacuum insulation panel employs annealed binderless glass fibers as a core material, thus ensuring superior thermal insulation performance and preventing out-gassing in a vacuum due to the absence of organic residues in the fibers, and thereby a vacuum level of the vacuum insulation panel can be maintained for a long period of time.


The present invention relates to a radiation curable paint composition and a molded product comprising a cured coating layer formed therefrom, and more specifically, to: a radiation curable paint composition comprising a polyfunctional polyurethane acrylate being at least pentafunctional, a mono- or difunctional polyurethane acrylate, a mono-, di- or trifunctional acrylate, a photopolymerization initiator, and a triazine-based UV absorber, wherein physical properties such as adhesion to a metal or plastic substrate, water resistance, moisture resistance, heat resistance, thermal shock resistance and the like are remarkable, and particularly, weather resistance is remarkable, and thus it is useful for a hard coating for a plastic substrate, and particularly, for an automobile headlamp; and a molded product comprising a cured coating layer formed therefrom.
