Our history

Founded in 1983 by Robert Tunnicliffe, a former Ford Motors engineer, Ventrolla was born from his quest to resolve draught issues in his own home.

What began as a handmade prototype evolved into the world’s first perimeter sealing system (VPSS) and sash removal system (SRS).

Designed to eliminate draughts, rattles and dust ingress, VPSS was awarded the prestigious Design Council Award (Engineering Components) shortly after its invention. This system, along with our SRS, remains central to our distinguished offering over 40 years later.

Perfection is imperceptible

No matter the property, no matter the complexity, our obsession means you don’t have to settle for anything less than perfection. So perfect, in fact, we don’t expect you to see the difference. Just feel it.

Experience begets expertise.

Our joinery houses are bastions of artisanal woodworking and technical fastidiousness. By blending time-honoured craftsmanship with innovative technology, like our VPSS and SRS systems, we enhance the character, value, and efficiency of historic homes, commercial buildings, and landmarks.

Our dedicated R&D experts are fixated on finding new ways to enhance our products. From smartphone-controlled sash openings to augmented reality visualisation, we rethink, redesign and revolutionise.
