Dear Customer,


UKCA Glass Marking


The UKCA (UK Conformity Assessment) mark is the new UK product marking that will be required for processed glass products for use in buildings being placed on the market in Great Britain (England, Wales and Scotland). It replaces products that previously required the CE mark.


Dual Seal Glass has started the changeover, which must be completed by the 31st December 2022. All processed glass manufactured by Dual Seal from the 1st January 2023 will be marked in accordance with the relevent product standard containing the prescribed information together with the UKCA mark.


During the transition period there will be some orders for projects that will contain CE marking and some for the same project may also contain UKCA marking. Both types of marking are valid during the changeover period.


Thank you for your continued support.

We are pleased to announce that dualseal has been awarded ISO 14001:2015 Environmental Management Systems and ISO 45001:2015 Occupational Health & Safety Management Systems. This has come after hours of hard work from Oliver, Health, Safety & Technical Manager, and an audit on Friday 15th May atdualseal by CEN Solutions.

Oliver Ashford played an important role in achieving this, and when asked, said, “Achieving these accreditations has been an in-depth process but well worth the hard work and effort, as they are the three main international standards in the construction industry and demonstrate our highest commitments and standards of compliance in place across all areas of our delivery. We’re incredibly proud to have obtained these certifications and achieve an integrated management system for all three standards, especially against the backdrop of the recent pandemic and the challenges that has presented the business, and it shows everyone’s hard work across the whole of the organisation to be able to achieve this.”

Similarly, these are accreditations which Managing Director, Nigel D Meredith, has aspired to have for years. Nigel said, “This is a great accolade for the company and shows how we have developed over the years and become aware of how we can make a difference to the environment by the way we produce and re-cycle responsibly. I would like to say a big thankyou to Oliver Ashworth, our QC Manager/Health & Safety Officer for his many hours of work establishing the systems required and to all employees for buying into this ethos.”

Lamination manager, Brijesh said “In production we are so busy, so it is good to be able to learn about other parts of running a business such as marketing and sales.  The module I am looking forward to the most is the quality assurance module.  We take quality so seriously here atdualseal I always welcome the opportunity to learn more in this area”.

dualseal are committed to developing all team members

UK manufacturing is going through an uncertain time, not least because there is a shortage of skilled employees and an ageing workforce.  With this in mind dualseal, who employ 150 local individuals put a strategy together, designed to provide a workplace in which individuals can learn and grow and where career development through education in embraced and encouraged.

Around 50% of the entire workforce are enrolled on an external qualification or have received formal training in the past 6 months, the majority of those who are not, have already recently received it.

The future is bright

dualseal is a place where people can learn and grow and have a long career with us. We now have people calling and emailing speculatively to enquire about vacancies.  This is because they have heard from our employees that it is a place to work that values and looks after its employees.  We have seen improvements in attendance and fewer individuals are leaving our employment.  dualseal are in the planning stage of a major apprenticeship scheme so we can recruit, develop and grow our own talent.
