Technology

Our energy-efficient wall system is engineered to provide exceptional protection against heat, cold, noise, and fire — all while ensuring lasting structural stability. With high-performance insulation and premium material layering, every wall is designed to meet the highest standards of comfort, safety, and durability.

Superior Protection with Our Wall System

On the interior side, double structural reinforcement is achieved through a combination of 12.5 mm fire-rated plasterboard and 15 mm engineered wood panels, offering outstanding static stability for decades to come.

All wall elements are precision-prefabricated in our Romanian facility, under controlled indoor conditions. This guarantees a consistently high build quality, with no exposure to moisture or weather during production. Thanks to this dry construction method, your home benefits from better thermal performance and shorter on-site assembly time.

Whether in the chill of winter or the heat of summer, our walls maintain a stable, pleasant indoor climate — reducing your energy costs and increasing long-term comfort.
