Monument protection authorities require preserving original building fabric during window restoration. Upgrading energy efficiency while maintaining authentic façade appearance is challenging. Traditional double or triple glazing is often too thick for historic window frames and lacks the textured look of old glass.
Vacuum-Insulating Glass Technology
AGC’s FINEO Heritage Series offers ultra-thin vacuum-insulating glass (10–17 mm) that fits into original frames without alteration. This makes it ideal for heritage buildings where preserving original frames is essential.
The Heritage Series combines vacuum glass with Fourcault glass, known for its wavy, textured surfaces, preserving the look of glass from 1880 to today. Five types: Classic, Classic Light, Classic Strong, Modern, and Traditional Light, reflect historical glass textures, keeping façades true to their era. 
Superior Thermal and Acoustic Insulation
FINEO Heritage achieves a U-value of 0.7 W/m²K versus over 5.8 W/m²K for single glazing. It reduces heat loss, improves thermal comfort, and offers sound insulation up to 40 dB, ideal for noisy environments.
Durability and Sustainability
With a 20-year guarantee and expected 60-year lifespan, FINEO is durable and low-maintenance. As a CE-marked European product, it supports sustainable, circular production.
