2 results about "Building envelope" patented technology

There are currently two major types of exterior building envelope finishing systems: window wall systems, and curtain wall systems. Window wall systems use panels which fit between concrete floor slaps, and hence, are prone to leakage and are not aesthetically appealing. Curtain wall systems are installed proud of the concrete slabs, so have better performance, but are expensive to install. The system of the invention has the high performance of a curtain wall system, with the ease of installation of a window wall system. The invention uses rigid panels which cover the face of a building like a curtain wall system, providing a complete gasketed seal without the need for caulking as in the case of window wall systems. The vertical mullions are notched, so that the mullions can be easily anchored to the upper and lower surfaces of the concrete slabs.

The invention relates to a PVC (Polyvinyl Chloride) wallboard without stabilizer pollution, which is characterized in that a perforation runner extrusion forming die is invented according to the specification and the shape of the PVC wallboard by adopting industrial chain manufacturing technologies of PVC granules without stabilizer pollution, an accurate measurement blanking machine, an ultrahigh-pressure single-screw extruder and the like invented by the inventor; and a set of operation technology for processing and manufacturing the PVC wallboard is designed. The processing and hot melting time of the PVC wallboard is controlled within 45 seconds and is far away from the HCL decomposition point of a PVC material, and the PVC wallboard which is waterproof, mildew-proof, fireproof, windproof, shockproof, acid-resistant, alkali-resistant, corrosion-resistant, weather-resistant, durable, heat-insulating, sound-insulating, environment-friendly and attractive is manufactured. The PVC wallboard has the advantages that the PVC wallboard is a full-function building material of a building envelope structure, the service life is more than 500 years, the market consumption is very huge, and the PVC wallboard is a new technology, a new material and a new product for industrially manufacturing houses, and is an important link of a 500-year house industry chain manufacturing technology.
