Vacuum Insulated Glass Solutions by CTWS

Werkman Tech & Fineo High-Performance Heritage Glazing

At CTWS, we specialise in the supply and installation of advanced Vacuum Insulated Glass (VIG) systems, working with leading manufacturers including Werkman Tech and Fineo. These cutting-edge glazing solutions represent the very latest in thermal performance technology, allowing homeowners to dramatically improve energy efficiency while retaining the character of original timber windows.

Operating throughout Dorset, Hampshire, Wiltshire, & parts of Somerset, and Devon, CTWS provides expert installation and restoration services for period, listed, and traditional properties. Our work extends beyond glazing upgrades to include full window restoration, repair, and conservation-led joinery solutions.

What is Vacuum Insulated Glass

Vacuum Insulated Glass uses a microscopic vacuum layer between panes to dramatically reduce heat transfer. Unlike conventional double or triple glazing, which relies on gas-filled cavities, VIG technology significantly improves insulation while allowing for ultra-slim units that are compatible with existing timber window frames.

The result is exceptional thermal performance without the bulk, weight, or visual compromise of traditional modern glazing systems.

Werkman Tech Vacuum Glass

Werkman Tech VIG is a premium heritage-focused solution designed for ultra-efficient thermal performance in slimline units starting from approximately 8mm thickness.

‍ ‍Key benefits include:

• Exceptional thermal efficiency with very low U-values

• Ideal for conservation and listed properties

• Slim profiles suitable for traditional sash and casement windows

• High performance without altering original window aesthetics

Werkman Tech is particularly well suited to projects where maximum thermal performance is the priority, and where homeowners want the most advanced insulation values available in a heritage-friendly format.

Fineo Vacuum Glass

Fineo Vacuum Glass offers a highly refined, ultra-thin glazing solution designed specifically for heritage applications where discretion and authenticity are essential.

‍ ‍Key benefits include:

• Extremely slim profile (starting from around 7–8mm)

• Excellent thermal and acoustic performance

• Minimal visual impact, ideal for sensitive restorations

• Suitable for listed buildings and conservation areas

Fineo is often the preferred choice where aesthetics, discretion, and conservation sensitivity are the primary considerations.

Which System is Right for You?

Both Werkman Tech and Fineo represent state-of-the-art glazing technology, and both significantly outperform traditional double and triple glazing systems.

At CTWS, we provide honest, expert guidance to help you choose the right solution:

• Werkman Tech is often selected where the highest possible thermal performance is the priority

• Fineo is frequently chosen where ultra-discreet appearance and conservation sensitivity are key considerations

In many cases, the best solution depends on the property type, existing window condition, and planning or conservation requirements. Our team will assess your windows and recommend the most suitable option for your home.

Premium Installation & Long-Term Value

Vacuum Insulated Glass represents a long-term investment in both comfort and energy efficiency. While the initial supply and installation cost is higher than standard double glazing, the significant reduction in heat loss can contribute to meaningful long-term energy savings over time.

For many homeowners, especially those with period or timber properties, VIG offers a rare opportunity to achieve modern thermal performance without replacing original windows.

State of the art hi-tech ultra slim by design

Vacuum glass features an ultra-slim, high-performance vacuum-insulated design, only 7.7mm thick making it an ideal modern glazing solution & retro fitting into existing sash frames, for listed and conservation area homes. With a thickness comparable to single glazing.

VIG a modern vacuum-insulated glass, provides insulation comparable to triple glazing while being as thin and lightweight as single glazing. It offers excellent thermal performance, improved durability, and is ideal for retrofitting older windows without altering their appearance & reduces your carbon footprint.

Superior thermal insulation (U-value 0.7 W/m2K) & acoustic enhancements that reduce external noise, preserving the aesthetic integrity of historic properties & enhancing energy efficiency. Its lightweight structure allows for easy integration into existing frames without compromising heritage architecture.
