Building with glass is currently all the rage and offers residents light, sun-filled living spaces. As the requirements in terms of energy efficiency and living comfort are also increasing, good heat insulation of windows and other glass surfaces is becoming increasingly important. Advances in the design of insulating glass and its bonding mean that extensively glazed buildings and energy-saving construction are no longer mutually exclusive. At the forefront in this respect is a dry bonding process that offers greater design flexibility in window construction.
“Dry Static Bonding” from Lohmann is essentially an insulating glass bonding process that bonds the sheet of glass directly into the window sash using a high-end adhesive tape. The double-sided mounting adhesive tape from the DuploCOLL 56000 range offers the required profile stability and provides a reliable barrier against the cold. “The high final strength and ageing resistance of the adhesive tape give the bonded frame a stable structure and guarantee a reliable load transfer”, explains Harald Krämer, Market Manager Architecture. A stabilising steel core inside the window profile is no longer required, saving the manufacturer material and production costs. Another advantage: The absence of any steel strengthening reduces the weight of the window and frees up the profile chamber for additional insulating material. Thermal bridges are thus eliminated and the heat insulation of the window is improved. The design of the window also offers greater protection against break-ins, as the bonding joint around the edge of the glass makes the sheet more difficult to press out.
The profile manufacturer can apply the adhesive tape directly to the existing window profile. Alternatively a suitable adapter profile which is already equipped with tape may be applied to the window profile. Both options can be integrated into the existing process so there is no need to invest in new machinery. Whether manual, semi-automatic or automatic – Lohmann engineers have the right solution for your adhesive tape application.
