Ventrolla Perimeter Sealing System (VPSS)

Intelligent draught-proofing

When it comes to draught-proofing heritage windows, you want to feel the difference, not see it. Our innovative draught-proofing technology creates an effective barrier against cold air entering your property.

Typically fitted as standard to all replacement sash and casement windows or doors. Using strips of low-friction Weatherfin polypropylene pile to seal gaps, creating an airtight seal, preventing heat or cool air from escaping your property.

The VPSS was created by Ventrolla’s founder, Robert Tunicliffe. Drawing on his experience designing gaskets and seals for Ford Motors, this innovative window seal has evolved over the last 40-years into a precision-manufactured system.

The process

VPSS for your existing windows and doors.

Restoration

Our master craftsmen meticulously restore each window, addressing issues like rotten timber, damaged cords, and faulty pulleys. We apply our unique VR90 Wood Repair System, a two-part epoxy resin, to reinforce tenon joints and fill sill cavities, enhancing the strength and longevity of your windows and doors.

VPPS upgrade

Regardless of shape or size of the window, the VPSS is installed to all areas discreetly – top of the box, mid rail, bottom rail, parting bead and staff bead. The system upgrades the performance of restored or new wooden windows and doors without affecting either their appearance or character. Our final quality inspection ensures optimal performance and operation.

Do I need to replace my sash windows to make them energy-efficient?

No, our renovation and draught-proofing system enhances energy efficiency without the need for replacement.

What is the Ventrolla Perimeter Sealing System (VPSS)?

The VPSS is our patented draught-proofing system that reduces noise, prevents draughts, and improves energy efficiency while preserving original window character.

How does the Ventrolla Perimeter Sealing System improve comfort levels?

The main complaints we hear about are draughty, rattling windows. Our draught proofing system closes the gap around the sashes; eliminating draughts, rattles and reducing dust ingress and heat loss.

Will renovation reduce outside noise levels?

Noise is subjective, but our Secondary Glazing systems and the Ventrolla Perimeter Sealing System (draught proofing) have been independently tested and proven to significantly reduce sound intrusion.
