The sealed unit double glazing or thermo is one of the most common types of glass used in construction. Due to their excellent thermal and acoustic properties DVH units have replaced the core with monolithic glass windows. One of the important elements of a DVH is the separator.
The most common sealed unit double glazing, DVH, are composed of two pieces of glass and a spacer around the edge profile of the unit DVH. Profile inside separator has a silica compound that acts as a moisture remover space between the glass pieces. The problem with aluminum separators is that aluminum is an excellent thermal conductor, allowing the cold outer reaches of the interior of the unit DVH. To prevent heat loss caused by traditional aluminum spacer units DVH, more and more consumers are demanding low-conductivity materials to separate glass panels. The call to this problem was WARM EDGE SPACER (warm edge). The warm edge spacers refer to a type of material separator used to separate glass panels in a unit DVH. If the material conducts less heat than a traditional aluminum separator glass edge is called warm edge spacer. Many of the new spacers are less conductive and higher performance than aluminum. Warm edge spacers improve the thermal performance of windows, reduce condensation, and proper machinery, allows quick easy production of DVH. The big problem with this type of separator is even a higher price than conventional aluminum spacer.
