Enter the innovative use of high performance windows and doors. To solve the challenge of temperature regulation without compromising on aesthetics, the architects leveraged AGG Insulglass LowE Plus^® clear double glazing in German-engineered aluplast uPVC window and door joinery. The resultant u-values of 1.7 – 1.8 are indicative of exceptional insulation, ensuring minimal heat transfer and, thus, better energy efficiency. Moreover, the SHGC (Solar Heat Gain Coefficient) values ranging between 0.24 – 0.43, demonstrate the glazing’s capacity to modulate the influx of solar radiation.

These glazing solutions, fabricated by Eurotech Windows, encompassed an eclectic blend of tilt-turn, sash, fixed, smart-slide, French and hinged door systems, thereby serving dual purposes. First, they acted as robust barriers, maintaining the home’s internal temperature, which synergized seamlessly with other energy efficient measures, such as the solar panels and underfloor heating. Second, they contributed aesthetically by enhancing the diffusion of natural light, a vital component in evoking the tranquility inherent in both Japanese and Scandinavian designs.

By integrating these high performance glazing systems with eight strategically placed skylights, the architects ensured the flood of controlled, abundant natural light throughout the property. This luminance accentuated the beauty of the interior elements, like the Taj Mahal quartzite stone, genuine oak flooring, and walnut timber accents.

Moreover, the choice of the aluplast uPVC Ideal 4000 system for the joinery further reiterated the project’s commitment to sustainability. uPVC, being recyclable, durable, and requiring minimal maintenance, made it an environmentally conscious selection. It also contributed to the home’s sound insulation, creating pockets of serenity, a necessary attribute for a dwelling inspired by Japanese zen and Scandinavian hygge.
