Sound Curtains

Sound Curtains offer maximum sound control and noise reduction using a combination of sound absorption and noise barrier material. The acoustic blankets have been used in many industrial, commercial and OEM noise control applications. The system can accommodate ventilation and access while maintaining high noise control. Product description: vinyl coated fiberglass cloth on 1" quilted fiberglass batting. Fire resistant, soundproof, flexible and custom mountable.

Cork

Cork flooring is made from bark peeled from cork oak trees. The cork oaks thrive and regenerate, while never being cut down, which makes them completely sustainable. Cork floors are durable and resilient, while offering softness and warmth (life-cycle savings as well as “quality of life” benefits). Cork floors are ideal for almost any room in the home. Cork flooring is easy to install and maintain, which makes it more cost-effective than other flooring surfaces.
Cork floors offer excellent sound absorption and acoustical excellence. Cork flooring radiates warmth and atmosphere, allowing you to express your personal taste freely. Cork tiles are available either with untreated surface finishes to which flooring urethane (we recommend waterbased) must be applied after installation, or pre-finished with urethane. Either option will bring pleasing results.

ETFE

Ethylene tetrafluoroethylene, colloquially known by its abbreviation ETFE, is a fluorocarbon-based polymer (a fluoropolymer): a kind of plastic. Trade name "Tefzel". It was designed to have high corrosion resistance and strength over a wide temperature range. In addition it has a high melting temperature and does not emit toxic fumes when ignited.





Compared to glass, ETFE film is 1% the weight, transmits more light and costs 24% to 70% less to install. It's also resilient (able to bear 400 times its own weight, self-cleaning (due to its nonstick surface) and recyclable. On the other hand it is prone to punctures by sharp edges, therefore it is mostly used for roofs.[1] In sheet form as commonly employed for architecture, it is able to stretch to three times its length without loss of elasticity. Employing heat welding, tears can be repaired with a patch or multiple sheets assembled into larger panels.
