What Sets Us Apart At Denval

we pride ourselves in implementing our core values throughout all aspects of the business and strive to exceed our customers expectations through the delivery of high quality architectural aluminium products and workmanship.

Our Core Values are Quality, Innovation, Accountability, and Teamwork

We have a dynamic team who will support you from design conception through to post installation services. If there is something in the envelope of the building you want us to incorporate into our package we will.

For example we are in the final stages of completion of the prestigious John Steet office block for JR Smart where we worked with the architects at the planning stage to achieve their design intent which needed to develop a thermally efficient building ensuring the occupier enjoys efficient running costs without compromising on the required aesthetics of the building.

Our site and production Quality teams work together to hand over our products snag and defect free allowing our customers a smooth completion of their projects. We believe that teamwork is essential to our business and the collaboration and cooperation between ourselves and our customers is fundamental in order to reach our shared goal of delivering a successful project.

We are committed to prioritising the safety of our colleagues, the public, and clients through implementation of Risk Assessments, training, education, safe practices of work and compliance with the latest health and safety legislation. Our site staff are trained to SMSTS, our production team are NVQ Level 2 fabricators and throughout the business we employ a team of highly skilled technical personnel with numerous years experience in the Aluminium and Glazing industry.

This year saw our first apprentice qualify through a government backed Apprenticeship Scheme supported by Coleg Sir Gar which we have now developed further in conjunction with XR Training to provide a bespoke NVQ Level 2 apprenticeship in the fabrication of aluminium glazed products which we are rolling out to encourage more young people into the industry.

We have recently begun to embark on a journey of collaboration with our clients to bring our Corporate Social Responsibility to the forefront of our business activities. We and have partnered with a company that is providing us support to engage with schools to deliver an unrivalled package of benefits to the communities in the location of each of our projects.
