OEM/ODM Aluminium Doors & Windows Supplier Serving the UK Market

Document L (amended June 2022) mandates whole-window U-values (Uw) of ≤ 1.4 W/(m²·K) for existing building replacements and ≤ 1.2 W/(m²·K) for new dwellings. Our systems deploy custom multi-chambered polyamide PA66 thermal barrier struts (ranging from 24mm to 44mm) coupled with soft-coat low-emissivity glass assemblies, warm-edge composite spacers, and 90% Argon gas cavities. This enables us to achieve verified Uw figures as low as 1.1 W/(m²·K) for double-glazed units and 0.82 W/(m²·K) for Passivhaus-standard triple-glazed configurations, comfortably exceeding current requirements and anticipating the Future Homes Standard 2025.

Yes. All export fenestration products manufactured for Great Britain and Northern Ireland carry full Declaration of Performance (DoP) documents and test reporting under designated standard BS EN 14351-1 (Windows and Doors). We supply thermal transmittance calculations verified in accordance with BS EN ISO 10077-1 and BS EN ISO 10077-2, as well as glass impact safety conformity to BS EN 12600 and BS EN 12150. These documents are directly accepted by local authority building control officers (LABC) and private approved inspectors across England, Scotland, and Wales.

Under Document F (Volume 1: Dwellings), background ventilation is compulsory, demanding equivalent areas between 4,000 mm² and 8,000 mm² per habitable room. We precision-machine concealed head drip trickle vents directly into our outer frames or install overhead acoustic trickle vents (sourced from premier British hardware partners such as Titon or Greenwood Airvac) during factory assembly. These units preserve the slimline aesthetic while eliminating draft complaints and passing airtightness pressure tests (BS EN 13141-1).

Our window suites and sliding doors are tested strictly against BS 6375-1 (Weather tightness). Utilizing a multi-stage pressure equalization chamber, internal concealed continuous drainage channels, and continuous vulcanized synthetic EPDM gaskets, our systems achieve Class 4 Air Permeability (600 Pa), Class 9A Water Tightness (600 Pa), and Class E2400 Wind Resistance. For exposed Scottish or South West coastal regions, we supply heavy-duty structural mullions and reinforced sill sub-cills (150mm–180mm projection) with concealed weep-hole drain systems.

Our standard OEM manufacturing cycle is 20 to 30 working days from final sign-off of shop drawings. Ocean transit to UK ports (Felixstowe, Southampton, or London Gateway) takes approximately 26 to 32 days. We offer complete Delivered Duty Paid (DDP) logistics, managing customs clearance (UK tariff code 76101000 for aluminium doors and windows), VAT processing, and onward flatbed transport with offload-ready crating directly to your jobsite or consolidation depot.

Yes. While RAL 7016 (Anthracite Grey) and RAL 9005 (Jet Black) represent over 70% of current UK architectural orders, our fully automated vertical powder-coating plant applies any RAL Classic, British Standard (BS 4800), or metallic anodized finish. Dual-colour finishing (e.g., Matt Anthracite Grey exterior with Traffic White RAL 9016 interior) is readily accommodated to harmonize with modern external cladding and light-reflective internal plasterboard finishes.
