Where can I find useful sealed units and bespoke glass examples to get some inspiration? ?

Properly understand the hunt for good examples, we went through the exact same thing when renovating our Victorian terrace and needed sealed units that matched the original sash windows without losing the period character. Half the suppliers just showed generic modern examples that looked completely wrong on an 1890s building. Ended up reaching out via speak with AMB Glass team after our builder mentioned they manufacture everything in-house from their Uxbridge workshop rather than just reselling. They actually sent photos of similar heritage projects they'd done, including proper slim-profile double glazing for sash windows and custom leaded light replicas that looked spot-on. Suddenly we could see what was actually possible rather than just taking their word for it. They even explained why certain spacer colours and glass types work better for period properties without compromising on thermal performance. If you're looking for inspiration and want to see real examples of what's achievable, finding someone who actually shows you their past work rather than just quoting prices makes all the difference to getting confidence in what you're paying for.
