Barsinghausen, November 12, 2025. The SCHOLLGLAS Group, together with the US-based Transparent Insulation pioneer LuxWall™, is presenting the latest generation of high-performance vacuum insulated technology with GEWE Enthermal™ and GEWE Enthermal Plus™.
Through this partnership, SCHOLLGLAS is making LuxWall’s Transparent Insulation technology exclusively available to customers in Germany for the first time. The innovative units combine exceptional insulation performance of only 0.3 W/m²K with a unit structure just 8-mm thin, opening new possibilities for renovation, restoration, and high-quality new construction projects.
Combined Expertise
The collaboration combines LuxWall’s pioneering role in Transparent Insulation with the comprehensive market access of the SCHOLLGLAS Group. The shared goal is to advance the adoption of high-performance building envelopes across key European markets.
“As a major European glass trading and processing group, we have always viewed it as our responsibility to develop glass innovations or identify them on the global market, make them operationally available, and actively bring them to market,” says Günter Weidemann, Owner and Managing Director of the SCHOLLGLAS Group. “The exclusive partnership with LuxWall is an important addition to our range of high-performance glass products that enhance the capabilities of the building envelope. Through our network of sales and production locations, we coordinate a robust supply chain to meet the growing demand for advanced glazing solutions for renovation and new construction”
The fine vacuum between the tempered safety glass panes of GEWE Enthermal, combined with a low-E coating, suppresses convectional and radiant heat transfer, two of the three heat transfer principles, and virtually eliminates heat conduction.
GEWE Enthermal: Lightweight, Slim, and Bright
The vision behind GEWE Enthermal is to transform windows from a weak point in the building envelope into a high-performance asset.
GEWE Enthermal achieves insulation values comparable to a brick wall with 10-cm of insulation. With a total thickness starting at just 8-mm and a weight reduction of over one-third compared to triple glazing, GEWE Enthermal is ideal for renovation and restoration projects. Even in historic buildings, original frames can often be retained while improving thermal and acoustic performance.
The 1:1 replacement capability enables modernization with minimal retrofitting effort. The improved insulation of refurbished window surfaces reduces building operating costs and may allow for the use of smaller HVAC systems, saving capital expenditure.
At the same time, the double-pane construction provides up to 10% higher light transmission than conventional triple-glazed units, allowing noticeably more natural daylight into interior spaces.
Patented Technology, Maximum Performance
GEWE Enthermal Transparent Insulation units are manufactured in exclusive partnership with LuxWall using a multi-patented process. The result is a combination of maximum performance and elegant aesthetics with a long service life, as GEWE Enthermal retains its insulating properties for decades.
“Germany is one of the most advanced markets when it comes to building performance standards. Our collaboration with SCHOLLGLAS marks an important milestone in scaling our Transparent Insulation technology across Europe,” said Scott Thomsen, CEO and Founder of LuxWall. “Together, we’re enabling the next-generation of high-performance buildings designed for lasting comfort and cost-savings.”
Flexible Extension to GEWE Enthermal Plus
GEWE Enthermal Plus expands the product range with hybrid structures that add an additional outer pane. These customized units achieve a minimum Ug value of 0.25 W/m²K, setting new benchmarks in insulation performance.
SCHOLLGLAS can integrate all common functional glass types as outer panes, including single-pane and laminated safety glass with optional solar or thermal protection coatings, and even bird-safe patterns. GEWE Enthermal Plus therefore offers maximum flexibility for demanding architectural applications in both existing and new buildings.
“By adding the GEWE Enthermal series to the SCHOLLGLAS product range, we now offer building owners, architects, and planners another highly efficient Transparent Insulation option that significantly improves energy performance and operating efficiency,” said Günter Weidemann.
GEWE Enthermal vacuum insulated units are available now. Interested parties can contact enthermal@schollglas.com for more information.
