At Slenderpane, we have a glass toughening solution for heritage panes that need toughening but are too small for most toughening plants, all this can be done in our own workshop in Haddenham. 🪟

Our expertise in the manufacturing of small slim heritage units and the introduction of a small toughening plant has allowed us to now process toughened glass efficiently with sizes down as small as 100×100mm. ✅
