Slimline heritage IGUs that combine slim sightlines and an authentic appearance with improved thermal performance.

SUNtec™ eDGe

The SUNtec™ eDGe range from Olympic Glass is designed for heritage and refurbishment projects where slim sightlines and authentic appearance matter. Combining advanced insulating glass technology with elegant slimline construction, the range helps improve comfort and thermal performance while respecting traditional window aesthetics.

Its slim construction suits traditional timber window designs, making it a refined choice for luxury refurbishment, conservation-led projects and heritage-sensitive renovations where preserving the look of the original windows is a priority.

The range comes in two options. SUNtec™ eDGe Ar uses an argon gas fill for improved thermal performance in everyday heritage applications. SUNtec™ eDGe Kr uses krypton for enhanced insulation in ultra-thin cavity constructions. Together they give specifiers a clear, straightforward choice for upgrading heritage glazing.
