In light of efforts to reduce wasteful usage of energy in order to achieve a low-carbon society, various policies are being successively strengthened in Japan as a means to increasing the thermal insulation performance of housing, such as a major revision of the “Energy Saving Standard” and addition of the “Top Runner System” for “windows” (sash / glass). In addition to plans to make the revised standard mandatory for all new housing by the year 2020, a number of new standards are being established with the goal of achieving a higher level of energy saving performance than this standard, such as the “Low-Carbon Structure and Other Component Accreditation Standard” and “Net Zero Energy House”. Therefore, increasing the performance of “windows” which constitute the main entry/exit point for heat, will lead to boosting the insulation performance of housing.

1) Expand Glass Area by Making Frame SlimmerWe started with the development process based on the thinking that insulation performance could be boosted by reducing the frame area that is exposed since it tends to conduct heat, and increasing the glass area which does not tend to conduct heat. The frame for the Samos X model that is being introduced was decreased in size while maintaining durability by using resin and aluminum with superior strength and adopting anchor type glazing channel. The same level of insulation perfor-mance as a conventional resin window frame has been achieved by maximizing the glass area.In addition, by adopting a “Frame in Structure” which the frame and window frame lines are aligned, insulation performance was increased as the heat loss was reduced by minimizing the area of frame that is exposed.

2) High Performance Glass Featuring High Thermal Insulation and LightnessAdoption of triple layer window for high thermal insulation.This triple layer window has a structure of “Smart Light Structure” where the special thin glass that is only 1.3mm thick is used for the middle layer of glass, achieving higher thermal insulation yet lightness the same as a double layer window.

3) High Performance Frame with High Thermal InsulationThe adoption of a “Multi-Layer Hollow Structure” with multiple hollow layers of resin which have low heat conduction are used on the indoor side, separated from the aluminum material on the indoor side, combined with a “Thermal Break Structure” connected to the resin material that has low conductivity, achieve high thermal insulation perfor-mance.
