Specialist Heritage Manufacturing Capabilities

Our plant is designed for precision. We can replicate the look of historic hand-drawn glass while incorporating modern low-emissivity coatings. Whether we are filling units with high-density Krypton or creating the perfect vacuum in our LandVac range, our equipment and our people are the best in the business.

Advanced Thermal Performance Engineering

Single glazing is a relic of the past; our manufacturing makes it obsolete. We pack maximum thermal properties into dimensions that conservation officers find invisible. We solve the conflict between energy standards and historical integrity, providing a solution that satisfies both the building inspector and the historian.

Vacuum Glazing Manufacturing Excellence

Very few can manufacture vacuum glazing; even fewer can do it for heritage properties. Our LandVac units are the pinnacle of what is possible – superior to triple glazing but a fraction of the weight and thickness. We make the “impossible” restoration projects viable.

Quality Standards and Certification

Our BS EN 1279 Parts 2 and 3 certification is our badge of honour. It proves our units are built to last in the real world, not just a lab. From the selection of the glass to the final gas-retention test, every step is a demonstration of our commitment to being the best.

When you choose SlimLite™, you choose a unit that is guaranteed to perform.
