Climatec Windows

What Climatec Windows does

Climatec Windows Limited is a privately held UK uPVC window and door manufacturer founded in 1993 and headquartered in Southend-on-Sea, Essex. Operating as part of The Climatec Group alongside aluminium sister company Alu-tec and FENSA-registered installation arm Climatec Home Improvements, the company manufactures and supplies bespoke fenestration products to trade installers, commercial projects, social housing providers, and new-build developers across a ~250-mile radius covering East Anglia, the Home Counties, and South East England. From a 50,000 ft² footprint across 10 factory units producing over 1,000 fabricated units per week, the company holds BFRC, Secured By Design, CE, PAS24, Document Q, BSI, and FENSA accreditations.

The core technology stack centres on third-party uPVC profile systems — REHAU Total 70 (70mm, 5/6-chambered), Calibre (45° chamfered, 55/67mm), REHAU Heritage vertical sliders, REHAU Rio flush sash, the premium Residence Collection (R7 7-chambered / R9 9-chambered), and Solidor 44mm composite doors with Brisant Ultion cylinders — assembled into casement, bay/bow, fully reversible, vertical slider, and flush sash windows and entrance, French, stable, patio (REHAU Slinova), and composite doors. Hardware is sourced from ERA, Yale, Pilkington, Coastal Group, and Glazpart; ordering is supported by the Window Designer Cloud online configurator. No proprietary AI, software platform, or data-asset is disclosed.

The business model is B2B trade fabrication: quote-based bespoke manufacturing to installer and commercial-customer specifications, with revenue from uPVC fabrication and supply, aluminium products via Alu-tec, and installation services via Climatec Home Improvements. GTM is sales-led through the website, multiple phone lines per division, contact-form enquiries, and direct trade relationships. Marketing is content-heavy (corporate site, quarterly Vista newsletter, YouTube videos, Information Centre) targeting top- and mid-funnel installer and commercial-buyer engagement. No public pricing tiers, no disclosed revenue, and no external funding are present.

Direct peers

• Eurocell plc: UK-listed PVC-U window, door, and roofline fabricator with a national branch network and B2B trade supply model. Closest direct comparable to Climatec's uPVC trade fabrication business, but at materially larger scale and geographic reach.
• Origin Global: UK aluminium windows, doors, and internal screening specialist. Comparable to Climatec's Alu-tec aluminium division as a focused UK aluminium fabricator serving trade and commercial customers.
• Masterframe Windows: UK PVC-U fabricator specialising in heritage and timber-alternative windows. Directly comparable to Climatec's Residence Collection, REHAU Heritage, and Period Door offerings in the premium heritage segment.

Broad incumbents

• Deceuninck UK: UK arm of Belgian group Deceuninck, manufacturing PVC-U profile systems and supporting fabrication partners. Climatec previously used Deceuninck's Slider24 system, and Deceuninck competes for the same fabricator customer base.
• Veka plc: UK subsidiary of VEKA AG, one of the largest global PVC-U profile manufacturers, with downstream fabrication capabilities. Operates at significantly greater scale than Climatec and supplies many of the same installer and trade customers.
• Profile 22 (Epwin Group): UK PVC-U profile manufacturer within the Epwin Group, supplying trade fabricators across new build and commercial segments. Overlaps with Climatec in profile supply and end-customer segments, but operates as a profile supplier rather than a fabricator.
• Synseal Extrusions: UK PVC-U profile extrusion business referenced by Climatec in its vertical slider product range. Operates in the same profile supply and fabrication ecosystem as Climatec's core product lines.
• AluK: Aluminium systems supplier (referenced in Climatec's own newsletters) serving UK fabricators and installers. Directly comparable to Alu-tec's supplier base and competes for the same commercial aluminium trade customers.
• REHAU UK: UK division of the German polymer group REHAU, Climatec's primary profile supplier for Total 70, Heritage, Rio, and Slinova systems. REHAU also fabricates its own products and serves competing trade fabricators in the same installer base.
