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.
Innovation
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.

Preserving a historical British chocolate-box village.
When the timber windows of 50 heritage properties began to show inevitable signs of ageing, such as rot and draughts, Bournville Village Trust turned to Ventrolla to sympathetically restore and renovate each window to its former glory.
Subtly transforming a historic schoolhouse.
For over a century, King Edward VI Handsworth School in Birmingham has stood as a symbol of educational excellence and architectural grandeur. Its 73 stately sash windows have long framed the school’s vibrant learning environment. However, time had diminished the windows’ original splendour, and the building failed to meet modern efficiency standards.
Bespoking sash windows for a 200-year-old Georgian home.
With a vision in mind but little more than the skeleton of a building, Dunsley House homeowners Louis and Haley turned to Ventrolla to bring their timber sash windows back to life during their extensive renovation project.
Reviving heritage: the Andersons’ journey with Ventrolla.
For Mr. and Mrs. Anderson, the windows and doors in their beautiful Grade II listed home needed to balance functionality with their passion for heritage preservation.

Restoring an iconic hospital façade.
On Nuttall Street in Hackney stands the venerable St Leonard’s Hospital, a Grade II listed building steeped in rich heritage. Our project was to breathe new life into 160 of its distinguished sash windows, each a silent witness to the hospital’s heroic past.
