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. ✅

At Slenderpane, our thin double glazed units come in a range of U-values to meet any project's needs, ensuring optimal energy efficiency.

Our warm edge spacers maintain sleek sightlines without compromising thermal performance. Choose from 6mm Heritage, 7mm, 8mm, 9mm, and 11mm options.

For a perfect fit, we recommend deducting at least 3mm from the opening size to get the ideal unit size. The lower the U-value, the better the insulation and thermal efficiency.
