In order to retrofit roller shutter casings with thermal and acoustic insulation, BOSIG GmbH, Germany, has turned to BASF's Basotect®, the thermoset melamine resin. This lightweight, flame-retardant foam is used in the Rolaflex® system, which simply and cost-effectively provides built-in or walled-in roller shutter casings with energy-efficient thermal and acoustic insulation, the company says. Thus, Basotect is making a contribution towards meeting the standards for passive and low-energy houses. The system will be showcased at the building and construction trade fair BAU 2009 in Munich, Germany from January 12 to 17, 2009.
As per the company, the gray, specially coated Basotect strips have a thermal conductivity of < 0.035 W/m .K, so they reliably prevent so-called thermal bridges, in other words, heat losses that can occur when roller shutter casings are inadequately insulated. The roller shutter casings are lined with one or more layers of Basotect and the strips are fastened with a pasty, solvent-free adhesive. It is not necessary to replace the windows or roller shutter casings, the system can be flexibly adapted to all kinds of roller shutter systems.
