As the UK’s premier manufacturer, SlimLite™ is where traditional craft meets laboratory-grade technology. Our facility produces the slimmest authentic units in the country. We don’t make “cookie-cutter” glass; we manufacture bespoke thermal barriers for the nation’s most important buildings.
Our Manufacturing Power:
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.
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.
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.
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.
Understanding our manufacturing capabilities helps architects, builders and homeowners appreciate why SlimLite delivers superior heritage double glazing solutions. Here are answers to common technical questions.
We specialise exclusively in heritage double glazing, with manufacturing processes designed specifically for slim units, krypton gas filling, and vacuum glazing that standard double glazing manufacturers cannot produce effectively.
Our manufacturing process uses minimal-depth warm-edge spacers, precision glass selection, and advanced edge sealing techniques. Combined with krypton gas or vacuum technology, this achieves exceptional thermal performance in ultra-thin profiles.
Yes, our manufacturing capabilities include bespoke heritage double glazing for windows of any dimension. From small sash window panes to large heritage range units, we manufacture to exact specifications.
We maintain BS EN 1279 certification including Parts 2 and 3, requiring rigorous quality management throughout our manufacturing process. Every unit undergoes inspection ensuring it meets the highest standards for heritage applications.
Primarily we manufacture glass units, though we partner with specialist timber window manufacturers for complete heritage window solutions. Our heritage double glazing integrates with premium timber frames for listed building and conservation area projects.
