W20 Metal Windows and Doors

We are able to replace the polular W20 steel window profile with a modern warmer thermal aluminium version, which not only replicates the originals good slim looks but we are also able to offer both 24mm and 28mm thick double glazed sealed units, giving a thermal U value of 1.6.

Available in all RAL colours, and with excellent lead times, our W20 style windows and doors are perfect for any project involving schools, work places and industrial renovations  where original looks and energy ratings are important.

Here at Jennyfields we pride ourselves as the experts in steel window and door replacements.
