Precision-engineered, thermal-break architectural glass and frame systems custom manufactured in Foshan, China for direct export to Irish contractors, developers, and trade distributors.
A comprehensive analysis on structural durability, thermal break geometry, air-tightness, and oceanfront corrosion resistance required under Irish Building Regulations.
Ireland's geographical exposure to North Atlantic low-pressure systems results in severe wind-driven rain and wind load demands under IS EN 1991-1-4. Traditional timber or basic steel bulkhead doors frequently fail due to wood rot, paint flaking, water seepage, or thermal bridging.
Our export-grade aluminum bulkhead doors utilize 6063-T6 architectural alloy profiles with a wall thickness exceeding 2.0mm. Combined with continuous EPDM triple-gasket seals and continuous pressure-equalized drainage tracks, these assemblies achieve a watertightness rating of up to 1200 Pa (Class E1200), ensuring zero water penetration into sub-level basements or exterior utility shafts during extreme weather events like Storm Eunice or Barra.
Under Ireland’s updated Building Regulations Part L (Conservation of Fuel and Energy), all building envelope components—including secondary bulkheads, roof access hatches, and subterranean entrance hatches—must conform to stringent thermal performance standards to meet Nearly Zero-Energy Building (nZEB) metrics.
We integrate multi-chambered polyamide 66 thermal break strips (PA66-GF25, 25% glass fiber reinforced) directly into the aluminum frame profile. When combined with dual or triple-pane Low-E insulated glass units (IGUs) filled with 90% Argon gas and warm-edge swisspacers, our bulkhead assemblies achieve structural overall U-values down to 0.85 W/m²K, preventing interior condensation and thermal draft losses.
A major failure mechanism for imported structural bulkhead hardware in coastal Irish regions (such as Galway Bay, West Cork, and Donegal) is airborne salt aerosol corrosion. Standard powder coating rapidly degrades within 24–36 months. Veltor applies a pre-anodization pretreatment process followed by Qualicoat Class 2 fluoropolymer or AkzoNobel Interpon D2525 powder coating. This provides a minimum 60–80 micron dry film thickness certified for ISO 12944 C5-M high-salinity marine atmospheric conditions, guaranteeing a 25-year structural aesthetic life cycle.
Custom structural bulkhead doors engineered for residential, commercial, agricultural, and historic retrofit developments throughout the Republic of Ireland.
Homes built along the Wild Atlantic Way face severe water ingress risks during high tides combined with heavy rainfall. Our hydraulic gas-strut aluminum basement bulkhead doors feature concealed stainless steel 316 multi-point locks, dual EPDM peripheral bladders, and integrated channel drains. This ensures an airtight and flood-resistant seal protecting below-grade living spaces, wine cellars, and plant rooms.
Refurbishing Georgian and Victorian properties in Dublin 2, Dublin 4, and Limerick center requires daylighting access hatches that comply with local planning guidelines. Our slim-profile, double-glazed walkable aluminum glass bulkhead doors deliver flood-rated sub-floor entry while maximizing natural light transmission (TLR > 78%) into basement office spaces or retail inventory rooms.
Boutique hotels, spa resorts, and restaurants along the Irish coastline utilize our large-span motorized glass aluminum bulkhead hatches to seamlessly open subterranean lounges, rooftop bars, and utility vaults to daylight while providing wind pressure resistance exceeding 2.4 kPa.

Market dynamics driving the adoption of custom Chinese extruded aluminum systems over traditional domestic steel or timber access options.
With the Sustainable Energy Authority of Ireland (SEAI) offering significant capital grants for residential and commercial deep retrofits, builders are mandated to eliminate cold-bridging at all entry points. Traditional steel cellar flap doors present severe thermal bridges that cause dampness, condensation mold, and failed BER (Building Energy Rating) audits. Direct sourcing of thermally broken aluminum bulkhead systems allows developers to achieve BER A2/A1 ratings while retaining competitive material costs.
Irish building material suppliers and main contractors often face supply chain bottlenecks and inflated intermediary margins from European distributors. By partnering directly with a top-tier Foshan manufacturer like Veltor Window & Door Co., Ltd., buyers receive custom CAD/BIM shop drawing customization, precision CNC fabrication, and factory-direct pricing—reducing total door schedule procurement costs by 30% to 45% without sacrificing technical quality or CE certification compliance.
Direct manufacturer capabilities tailored for smooth international project delivery to Dublin Port, Cork, and Shannon.
No mandatory standardized sizes. Every bulkhead door, roof hatch, and glazed casement unit is engineered against buyer-provided structural elevations, CAD files, or structural opening dimensions.
Equipped with 5-axis double-head CNC profile machining centers, guaranteeing corner crimping alignment tolerance within ±0.5mm for flawless frame weather-sealing and hardware mounting.
Units are wrapped in anti-scratch protective film, fitted with impact-resistant corner guards, separated by foam layers, and packed in ISPM-15 compliant fumigated plywood crates clearly labeled by room/opening number for rapid site installation.
Complete handling of FOB, CIF, or DDP (Delivered Duty Paid) ocean freight to Dublin Port, Port of Cork, or direct site delivery across Ireland, including full customs export declaration documentation.
Essential answers regarding compliance, shipping schedules, thermal engineering, and structural customization.
Our bulkhead access systems are engineered with multi-chamber polyamide thermal break profiles (PA66-GF25) and factory-fitted perimeter EPDM weather seals. Glass panels feature dual or triple glazing with Low-E coatings and Argon gas fills, yielding overall U-values down to 0.85 W/m²K—fully satisfying Irish Part L energy conservation requirements and preventing interior cold-bridging condensation.
Yes. For installations within 5 km of the Irish ocean coastline (ISO 12944 C5-M marine atmospheric environment), we utilize a multi-stage pre-anodization treatment topped with Qualicoat Class 2 hyper-durable powder coating (AkzoNobel Interpon D2525). This coating passes 2,000 hours of acetic acid salt spray (AASS) testing, completely preventing salt air pitting and corrosion.
Production takes approximately 20 to 25 business days following final CAD shop drawing sign-off and deposit receipt. Ocean container shipping from Shenzhen/Guangzhou ports to Dublin Port or Port of Cork typically takes 30 to 35 calendar days. We provide end-to-end tracking and direct bill of lading documentation.
Yes, our heavy-duty bulkhead doors are certified under EN 12207 for air permeability (Class 4) and EN 12208 for watertightness (up to Class E1200, 1200 Pa static water head). Frame structures are verified against IS EN 1991-1-4 wind load requirements, easily withstanding coastal gusts up to 180 km/h.
After receiving your structural opening dimensions or architectural PDF/DWG plans, our dedicated engineering desk generates comprehensive 2D/3D BIM CAD shop drawings detailing profile cross-sections, drainage paths, lock placement, and threshold details for your written approval before any profile extrusion or cutting begins.
We supply both manual hydraulic gas-strut lift systems (using SS316 gas pistons) and fully automated 24V DC electric linear actuators. Automated options can be interfaced with smart home controllers, rain sensors, or emergency egress switches complying with Irish fire safety egress regulations (Part B).
