Modern architecture requires new standards in the technical, functional and aesthetic sphere. The changing legal requirements for construction joinery, as well as, above all, the expectations of customers looking for warmer and warmer windows are trends that cannot be left indifferent to.
IDEAL 7000 is an example of the synergistic use of the properties of profiles and insulating glass in order to create windows with very low thermal transmittance. The heat transfer coefficient of the profiles with the Uf value of 1,1-1,0 W / m2K obtained in the tests, combined with the possibility of using wider and warmer glazing units up to 51 mm wide, guarantees the best thermal parameters of the window.
It is a system with an external seal, which makes it possible to offer an energy-saving solution also for glazed structures, without the need to use adapters. A large chamber with solid steel reinforcement guarantees the stability of the frame. The system enables easy connection of frames with other series of profiles with a depth of 85 mm. It is a system with an external seal, which makes it possible to offer an energy-saving solution also for glazed structures, without the need to use adapters.
The Ideal 7000 series is a multifunctional system that uses the MULTIFALZ technology, i.e. the optional possibility of using the glued-in glass technology. Thanks to the new geometry of the glazing rebate, it is not only possible to use conventional glazing, but also to glue the glazing. These technologies can be used alternately or combined depending on the needs, e.g. it is possible to improve the thermal properties of the structure by eliminating steel reinforcements and gluing glass panes, or using larger window sizes, colors, etc., with both steel reinforcement and glass gluing technology. The optional use of glass bonding technology allows for even greater stability of the windows. Due to the permanent bonding of the glass and the sash, the risk of warping, bending and subsidence of the sash is reduced, thus extending the life of the sashes without the need to adjust them.
"Powerdur inside" - an innovative technology of pvc profiles construction with the use of special thermoplastic inserts reinforced with ultradur® high speed glass fiber, developed in cooperation with BASF.
IDEAL 7000 is a perfect example of a "hybrid" solution, in which, on the one hand, we increase the depth of the profiles to 85 mm, increase the number of chambers, enable glazing of energy-saving glazing units with a width of 51 mm, and on the other hand we eliminate steel reinforcements, i.e. elements that negatively affect the properties thermal structures. The glass-fiber reinforced thermoplastic replaces the steel used in conventional PVC window frames and provides significantly better thermal insulation properties with the same mechanical properties of the window.
Thanks to the elimination of steel reinforcements within the Ideal 7000 "powerdur inside" profiles, thermal bridges are limited, and the heat transfer coefficient of the frames for this series is Uf = 1.0W / m2K, which is a very good result for a system with external sealing. The structure of the profiles also allows for further improvement of the thermal permeability of sections by optionally filling some internal chambers with thermal insulation material.
Metal stiffening in the profiles of window frames creates a thermal bridge due to high thermal conductivity. The extremely good mechanical properties of the Ultradur High Speed material make the material suitable for use in window frames. The use of powerdur allows for a significant improvement in the thermal properties of the profiles, which is largely related to the thermal conductivity of Ultradur High Speed, which is 50 times lower than that of steel.
This is very good news in the context of meeting the requirements of the regulation on technical conditions to be met by buildings and their location, in which the requirements for window joinery have been tightened by specifying the minimum thermal insulation coefficient from 01/01/2017 at the level of Uw (max) = 1.1W / ( m2 * K), and from 01/01/2021 already at the level of - Uw (max) = 0.9 W / (m2 * K)).
Improving thermal properties was undoubtedly one of the basic goals when designing this system, however, the elimination of steel reinforcements from the frames also brings a number of additional benefits for window producers in the form of improved production processes by: reducing the processes related to storage, cutting and screwing of steel reinforcements, as well as less wear on saws for cutting steel.
