Many thanks to Sealed Units Online. You have helped us to turn our draughty old Victorian house into a much warmer place to spend the winter! The whole ordering process was extremely simple with the very accurately made glass units arriving on time and in perfect condition. Great work! Thanks!

I purchased over 20 sealed units to change all of the glass in my house. Delivery was quicker than expected and all units were to specification, including different thicknesses, different spacers, some toughened glass, some obscured, some clear. I enjoyed using the website, ordering was easy with the help of Customer Services, in all a good experience.
