Our extruded vinyl and precision-welded combination windows are custom-fabricated to fit structural bay assemblies, bow extensions, and high-performance architectural openings.
As Ireland accelerates toward stringent Nearly Zero Energy Buildings (nZEB) standards and Part L compliance, local window distributors, developers, and general contractors demand factory-direct OEM vinyl bay windows that combine structural rigidity with superior thermal performance.
The Sustainable Energy Authority of Ireland (SEAI) offers significant home energy upgrade grants requiring strict Building Energy Rating (BER) improvements. Our high-density, multi-chamber uPVC profile systems with argon-filled Loʳ-366 triple glazing deliver ultra-low U-values (down to 0.8 W/m²K), easily surpassing Irish thermal bridge and transmittance thresholds.
Coastal developments along the Wild Atlantic Way (Galway, Kerry, Mayo, Cork) face severe driving rain and corrosive marine winds. Our virgin vinyl profiles are UV-stabilized and non-corrosive, featuring fusion-welded corner joints that eliminate water ingress and structural deterioration common in mechanically fastened alternatives.
From Dublin Victorian terraced refurbishments to suburban residential developments in Kildare and Meath, bay windows represent a key architectural feature. OEM production allows custom 30-degree, 45-degree, and 90-degree bay angle corner posts with integrated structural mullions to preserve original sightlines.
Our custom manufacturing setup allows Irish commercial buyers to order tailored vinyl bay window configurations designed specifically for regional microclimates and structural aesthetics.
In mature housing estates across Dublin 4, Rathmines, and Dun Laoghaire, single-glazed timber bay windows suffer from draughts, high heating bills, and rot. Our factory crafts custom OEM vinyl bay windows featuring integrated vertical sash or tilt-and-turn sashes that replicate historic proportions while lowering sound transmission from traffic by up to 42 dB Rw.
Exposed coastal projects require fenestration units capable of handling gust wind pressures surpassing 2400 Pa. By pairing fusion-welded virgin PVC-U frames with warm-edge composite spacer bars and Loʳ-366 thermal coatings, our bay units keep oceanfront interiors warm, moisture-free, and draft-resistant year-round.
Comprehensive physical and thermal test data comparison engineered for B2B procurement officers, structural engineers, and architectural specifiers.

We own the entire manufacturing chain — from raw PVC profile extrusion to automated glass cutting, gas filling, and structural bay kit assembly.
Every bay window opening on an Irish building site presents unique tolerances. We manufacture all units to order in precise 1/8-inch (3mm) increments, eliminating oversized masonry trim, unsightly sealants, or compromised perimeter insulation.
Unlike mechanically screwed frames that loosen during transit or expand/contract under extreme weather, our fusion-welded frame and sash corners melt into a single structural body. No corner gaskets to shrink, leak, or fail over time.
We supply Irish distributors, hardware groups, and project builders directly. Orders are fully crated, edge-protected, and palletized for safe oceanic container shipment directly to the Port of Dublin or Port of Cork with complete hardware labeling.
Everything Irish architects, contractors, and fenestration importers need to know about specifying, ordering, and importing our custom vinyl bay windows.
Our vinyl bay window profiles are designed with multi-chamber thermal breaks and accommodate up to 44mm triple-glazed insulating units with warm-edge spacers. This enables U-values as low as 0.78 W/m²K, comfortably meeting and exceeding Part L (Conservation of Fuel and Energy) targets. Additionally, frame heads can be factory-milled for integrated trickle vents to meet Part F ventilation specifications.
Yes. As a direct OEM factory, we produce custom bay pole assemblies and variable-angle corner couplers (30°, 45°, 60°, 90° box bays, and custom curved bow windows). All bay corner profiles include heavy-duty internal aluminum or galvanized steel reinforcements engineered to withstand wind uplift and structural roof loads.
Fusion welding heats the uPVC vinyl frame and sash corners to 250°C and fuses them under pressure into a continuous monolithic structure. Unlike mechanically screwed corners that rely on gaskets and sealants (which deteriorate under harsh sea spray and thermal expansion cycles in coastal Ireland), fusion welds are 100% airtight, watertight, and structurally permanent.
Standard manufacturing lead times are 2 to 3 weeks upon final CAD shop drawing sign-off. We offer full container load (FCL) and consolidated less-than-container load (LCL) freight solutions. All products are packed in reinforced steel/wooden crates with heavy-duty corner guards to ensure flawless arrival at Dublin, Cork, or Shannon ports.
We offer a Limited Lifetime Factory Warranty covering vinyl extrusion integrity, colorfastness (no yellowing or chalking under UV exposure), corner fusion welds, and insulating glass seal failure. Hardware components carry up to a 10-year anti-corrosion guarantee.
