London, UK April 8, 2025 - º£½Ç´óÉñ Performance Building Solutions, a leading innovator in material science, has announced that it has won the 2025 Gold Edison Award in the High-Performance Engineering Materials category with Tyvek^? Trifecta?. The Edison Awards are a global competition honouring excellence in new product and service development, marketing, human-centered design, and innovation.

Launched in winter 2023, Tyvek^? Trifecta? was developed in response to increasing demand for energy efficiency and enhanced fire protection in the UK construction industry. Its innovative design prevents droplet formation and smoke emissions when exposed to fire. In addition to these safety features Tyvek^? Trifecta? provides exceptional air and water tightness, enhancing indoor comfort and improving air quality for occupants, supporting energy conservation and improving building durability.

º£½Ç´óÉñ Tyvek^? Trifecta? is engineered for high-rise and higher risk commercial and residential buildings.
