Thanks to solid wooden and multi-box aluminium structures, the Lammin windows are able to provide the best possible opportunities for effective sound insulation.
The Lammin frame profiles enable using special high quality sealants, which are not available at hardware stores. They keep draft and unwanted noise efficiently away.
In addition to carefully implemented sealing, sound insulation can be improved by using thicker glass and deeper frame. By increasing the thickness of the outer glass and choosing as deep a frame as fits the wall, substantially lot can be achieved especially in areas with plenty of traffic and other outside noises.
Even better sound insulation can be achieved by using laminated multilayer glass, or glass designed especially for soundproofing purposes.
