Parc Gelli Werd industrial park with torverk q doors

British Business Park Achieves BREEAM Excellent rating

The Project

Torverk Industrial Doors collaborates with British door specialists, HAG Ltd. & the Welsh Government, in South Wales, UK.

Presenting our recent partnership with British door specialists HAG Ltd. at Parc Gelli Werdd, South Wales, featuring 15 Q doors – a robust and highly insulated industrial door systems.

Parc Gelli Werdd is a new and sustainable development of state-of-the-art workshops, industrial units & offices, situated 1 hour from Cardiff, the capital city of Wales. The units are designed to be flexible & are primarily aimed at the following industries: advanced manufacturing, agri-food technology, creative and energy & environment. Externally, the development includes ample car parking, electric vehicle charging points, service yard and bike store as well as extensive landscaping.

The primary goal of this business park centred on sustainability in both its design and operation. By incorporating Active Building and Passivhaus principles, which emphasise high insulation levels, our top-tier Q doors, known for their high insulation and durability, perfectly complemented the core design requirements.

The project, aiming for ‘Net Zero carbon in-use,’ has achieved BREEAM “Excellent” and EPC “A” ratings. BREEAM assesses sustainability across energy, water, materials, and more, while in the UK, EPC rates energy efficiency from A to G based on factors like insulation and heating. Achieving both ratings is highly commendable and signals a highly sustainable and energy-efficient building.

The Product

Q Doors offer excellent thermal insulation, ensuring long-term cost savings and enhancing both security and the aesthetic appeal of the building.

As a versatile bi-folding product, Q Doors can be externally fitted to address space constraints, providing additional room in the appliance bays. Numerous customisation options are available to tailor your Q Door to specific requirements, including insulated double-glazed windows, colour choices, and the option for manual or electric operation.

In this environment, aligned with the sustainability goals, we offered customisation by utilizing personnel doors, which decreases the entrance and exit space compared to opening the entire Q door. This approach conserves energy, consequently lowering the building’s carbon footprint.

The Q Doors sealing system complies with top European requirements, and still met them at 3 times the required test pressure! (The top European class 3 for air leakage describes air leakage (T Value) as at best 1.5m3/m2/h at 50 Pa pressure. i.e. 1.5m3/m2/h to 150 Pa).


Building upon our long-standing relationship with HAG Ltd. we were thrilled to be involved in such an exciting and progressive project, incorporating sustainability principles, the flexibility of pedestrian doorsets in the Q Doors, as well as offering exceptional levels of both security & thermal protection.

For more than 20 years, we have worked closely with HAG Ltd, whose philosophy aligns seamlessly with Torverk’s values. With an emphasis and commitment to providing customers with cost-effective and forward-thinking solutions.
