The TERMI-K Plus system is supplied by UKEG for the construction of steel frames for windows and doors with thermal break. The profiles are manufactured using two steel tubes (steel sheet thickness of 1.5 mm) with a central component in pultruded fiberglass and a core in rigid polyurethane foam with a low thermal conductivity. This last component has high mechanical resistance, and it is designed to interrupt the heat flow, and increase soundproofing. The sections of the profiles are 80 mm deep and with variable widths from 25 mm to 50 mm. The extreme strength of the steel – combined with the characteristics of the fiberglass and the series of accessories chosen and designed specifically – allows the creation of doors and windows with large dimensions and a minimum amount of frame on view. The “closed joint” gasket system allows the achievement of high performance in terms of air and water tightness and control. The sturdiness of the profiles allows high safety performances against extreme atmospheric events, guaranteeing the required high levels of heat and sound insulation and safety. The profile, thanks to its perfect flatness and precision, ensures ease and speed in welding and cutting operations. The treated fiberglass component allows the use of powder coating, without any deformation of the profile.
