Highest standards, as standard

Large national organisations that make thousands of windows each week have immaculate production procedures and set very high standards. 

When they outsource their sash window needs they expect suppliers to meet these standards.   

Each time we are asked, any higher standard set as a result becomes the new minimum that we make every window to, and not just those for the nationals.

Hassle free innovations

We don’t stop there either, Everyday we look at minor problems or customer feedback to improve our products or eliminate issues. That’s why we invented self-adhesive foam cill pads to prevent any chance of water ingress, foam baffles to reduce air infiltration pads, balance retaining cills to secure balances for life, two part pivot bars and even strapping for carry handles to make handling on site easier.

A supply partner you can trust

As the UK’s longest established company dedicated to PVC-U sash windows, we’ll do what we can to help you win orders. If things don’t quite go to plan, we really do help sort it out. We’re just a phone call away.

Trusting any company with your client’s order, you need to be certain they will deliver, on time and in full. You should always use a dedicated sash manufacturer for two important reasons:

  • If a company makes everything, they don’t invest in bespoke solutions to overcome system weaknesses, nor do they offer anything other than standard solutions.
  • Most casement fabricators actually sub contract their sash windows. You pay an extra margin for someone else to make your windows.
