21st Century Machining Meets Traditionally Handcrafted Sightlines

Designed to eliminate draughts, rattles and dust ingress, the Ventrolla Perimeter Sealing System was awarded the prestigious Design Council Award (Engineering Components) in 1986. Using strips of low-friction Weatherfin polypropylene pile to seal the gaps, this patented system, along with our innovative sash removal system, are still core heritage renovation products 35 years on.

With workshops based in Harrogate, Henley-on-Thames, and Lockerbie, manufacturing our products in-house gives all parties involved complete control of the process from start to finish – from customisation to pricing and everything in between.

We were most impressed with the speed of your reply, the sympathy you had with the building’s integrity, the quality of your demo kit and the attention to detail in your quote. You are an excellent advocate for your company.
