About Us


Zero International was established in the USA in 1924 by two Hungarian immigrants who, starting out with ‘nothing’, named their new company ‘Zero’. For 90 years, Zero has been designing and manufacturing window and door seals and sealing systems, and is known worldwide for its acoustic ‘soundtrap’ systems. Zero Seal Systems Ltd was formed in the UK in 1997, and has rapidly become known as a reliable supplier of quality products to the architectural hardware, door and partitioning industries.

As the company has grown, so we have added specialist products designed specifically for these markets; today, we have brought our product package together in this website. It does not show all the products available, so please ask us if you require something out of the ordinary.

The ZEROplus range is exactly what it says – Zero products plus other products that are specified by architects and used for door openings.



Our product range now extends to virtually anything that can be fitted to a door; in fact we sell everything except the door! Not just door seals to seal it, but hinges to hang it, stays to limit it, bolts to bolt it, intumescent to fireproof it, panic bolts to exit it, louvres to ventilate it, windows, vision frames and porthole windows to let light through it, closers and floor-springs to close it, and door handles to operate it.

Ancillary products now include finger protection strips, letter plates, door viewers, sliding door gear, door selectors, glass, louvre mesh, glazing tapes, frame fasteners, privacy screens and a lot more besides.



We take great pride in our customer service. Indeed, our business reputation has been built on the service levels we offer. Over the years we have steadily increased stocks to meet demand and maintain service levels. We now occupy a modern 12,000 sq ft warehouse and office unit near Stafford. However we do recognise that nobody is perfect, and mistakes can happen. If something doesn’t go according to plan we will always do our utmost to put it right as quickly as possible.

Zero Seal Systems Ltd is an ISO9001:2008 accredited company and operate a fully documented Quality Management System.



All our staff are hands-on and have spent time working in our warehouse and handling the products we sell. This means they can offer full product technical support whether on the phone, by email, or face to face.



Our company has a culture of continuous improvement, for services and products. In the interests of continuous product improvement, we reserve the right to alter the specification and detail of items shown on this website without notice. Zero Seal Systems Ltd accepts no liability howsoever arising from errors or omissions on this website.

We believe service is vitally important and we have built our business on meeting and trying to exceed our customers’ requirements. We operate in an industry where service levels are notoriously poor and we have tried to buck the trend.
