Welcome To Met Therm Windows

Met Therm is a family-run business on the Hampshire/West Sussex border. Our dedicated team draw on extensive experience within the replacement steel windows industry to meet the needs of our customers.

Recognising the distinctive and coveted features of steel windows and doors, we have designed and manufactured a composite aluminium product which solves the problems traditional and period windows can create.

Our product reflects our commitment to quality. It offers residential customers an opportunity to enjoy the benefits of a modern window that is almost indistinguishable from the original. You can personalise our products by selecting hinges, handles and paint finish to ensure an authentic replacement, every time.

We’re happy to discuss your specific requirements and can tailor our products, where possible, to meet your needs.

At Met Therm Windows, we provide a wide range of doors and windows including a variety of metal windows, period windows and bespoke windows.
