Abstract: Disclosed are a sound absorbing sheet having a micro resonant structure and capable of improving sound absorption performance up to the low frequency band by means of the micro resonance principle, a method for manufacturing same, and a sound absorption type soundproof panel using same. The sound absorbing sheet according to the present invention has multiple uneven patterns configured to have convex parts and concave parts on one surface of a porous base material, and the area ratio of the concave part determined by the following formula 1 is 40 to 99%. The area corresponding to the concave part has a lower air permeability than the area corresponding to the convex part. Area ratio of concave portion=[area portion of concave portion]/[area portion of porous base material].

Abstract: Provided is a sound absorption sheet comprising: a porous substrate; and a micro-resonance layer having a pattern of a plurality of sound-absorbing holes penetrating both surfaces thereof. Also provided is a sound absorbing soundproofing panel, the exterior surface of which is covered with the sound absorption sheet comprising: the porous substrate; and the micro-resonance layer having a pattern of a plurality of sound-absorbing holes penetrating both surfaces thereof.

Abstract: A hood insulator including a non-woven fabric and a fine resonance layer comprises a porous substrate and a skin material disposed on a surface of the porous substrate, wherein the skin material comprises the non-woven fabric and the fine resonance layer, the fine resonance layer includes a plurality of perforations, and the fine resonance layer is disposed on the non-woven fabric.

Abstract: The present invention relates to a sound absorbing sheet having excellent sound absorbing performance and surface decorative effects. The sound absorbing sheet of the present invention is characterized by comprising a base and having an average sound absorption of 0.4 or higher in a frequency range of 200 to 2000 Hz. The permeability and air porosity of a base layer of the sound absorbing sheet of the present invention may be adjusted, thereby achieving significantly superior effects of sound absorbing performance despite the thinness of the sound absorbing sheet.

Abstract: The present invention relates to a surface-waterproof sheet for inorganic boards including multi-use non-woven fabrics and a waterproof coating layer, and a method of manufacturing the same. The method includes preparing a multi-use non-woven fabric composed of cellulose fibers, glass fibers and organic fibers; preparing a waterproof coating solution containing a powdery acrylic binder, water, an inorganic filler, a water repellent, a pigment and an antimicrobial agent; and coating the waterproof coating solution on the multi-use non-woven fabric, followed by drying the waterproof coating solution, thereby providing surface-waterproof sheet for inorganic boards for buildings, which has improved adhesion to the inorganic board and economic feasibility.

Abstract: The present invention relates to a panel installation set used to finish the surface of a building, and to a method of installing panels using the panel installation set. The panel installation set comprises a support member (10) having a coupling projection (15) and a panel (20) having a coupling groove (25). The installation method includes the steps of fixing a support member (10) having a coupling projection to a building and assembling a panel (20) having a coupling groove (25) to the support member (10) in a manner such that the coupling projection (15) is inserted into the coupling groove (25). According to the present invention, since panels are assembled in a sliding manner, the panel installation set has the advantage of enabling easy and simple assembly of the panels, and reducing installation cost by reducing the use of subsidiary material.
