Custom OEM/ODM extruded profiles engineered for low thermal conductivity, high airtightness (EN 1026 Class 4), and supreme water tightness (EN 1027 9A).
The construction sector across Central Europe, particularly in the Slovak Republic (Slovensko), has undergone an unprecedented transformation driven by strict energy performance mandates. With the adoption of the European Energy Performance of Buildings Directive (EPBD) and local building standards such as STN 73 0540-2 (Thermal Protection of Buildings and Buildings Components), requirements for building envelope integrity have never been more demanding. Achieving the coveted A0 Energy Class Rating for ultra-low energy and passive buildings in Slovakia mandates holistic fenestration engineering—where high-performance window sealing systems, EPDM gaskets, and co-extruded polyamide thermal break barriers serve as the critical line of defense against unwanted heat exchange, infiltration, and structural moisture degradation.
Information Gain Insight: A window or curtain wall system is only as effective as its secondary and perimeter seal integrity. While triple-pane glass units achieve Ug values of 0.5 W/m²K, micro-gaps around uncalibrated perimeter gaskets can degrade the installed system's overall Uw value by as much as 35% through wind-driven infiltration and thermal bridging in cold alpine zones.
As a leading project-driven manufacturer and export supplier of architectural aluminum systems, thermal break window gaskets, and custom weatherstripping solutions, ALUCCO (under GOMAX Emlak Gayrimenkul Insaat Dis Ticaret Ltd. Sti.) provides end-to-end OEM (Original Equipment Manufacturer) and ODM (Original Design Manufacturer) capabilities. Operating out of Turkey's premier industrial aluminum extrusion cluster and serving developers, window fabricators, and façade contractors throughout Bratislava, Košice, Žilina, Poprad, and Prešov, we bridge the gap between architectural vision and certified physical compliance.
Analyzing local procurement behavior and engineering search intent across Slovakia reveals distinct regional climatic pressures that demand tailored window seal engineering:
Multi-lip EPDM and TPE weatherstripping engineered to guarantee Class 4 air tightness, eliminating micro-convection currents across high-rise curtain walls.
Continuous vulcanized corner seals and internal drainage channel gaskets designed to resist static water pressure up to 9A (600 Pa) and E750 special ratings.
Interlocking polyamide (PA66 GF25) thermal breaks with embedded sponge rubber gaskets, pushing composite window U-values down to $U_w \le 0.9$ W/m²K.
Selecting the appropriate polymer compound for architectural window seals, lift-and-slide door gaskets, and structural glazing gaskets dictates the long-term service life of the fenestration system. Below is an engineering comparison matrix of sealing polymers routinely customized for our Slovakian OEM/ODM clients:
| Polymer Type | Hardness (Shore A) | Temp. Resistance (°C) | Compression Set (22h @ 70°C) | UV & Ozone Resistance | Recommended Application |
|---|---|---|---|---|---|
| Peroxide-Cured EPDM | 55 – 75 ±5 | -40°C to +125°C | < 20% (Excellent) | Superior (30+ years) | Primary glazing seals, exterior frame gaskets, lift-and-slide bottom tracks. |
| Foamed / Cellular EPDM | 20 – 35 ±5 | -40°C to +110°C | < 25% (Very Good) | Superior | Acoustic insulation core, frame rebate seals, expansion joint fillers. |
| Thermoplastic Elastomer (TPE) | 60 – 80 ±5 | -30°C to +90°C | < 35% (Moderate) | Good (Requires UV stabilizers) | Welded sash gaskets, interior decorative trims, economical PVC profile co-extrusion. |
| Structural Silicone (VMQ) | 50 – 70 ±5 | -60°C to +200°C | < 15% (Outstanding) | Impervious | Structural silicone glazing (SSG) curtain walls, extreme cold Tatras applications. |
In luxury residential construction across Žilina, Poprad, and Liptovský Mikuláš, massive lift-and-slide aluminum patio doors are the norm. These large glass expanses (often weighing over 350 kg per sash) require heavy-duty seal design. Our OEM EKO NFRC triple-glazed lift-and-slide sealing profiles integrate dual-durometer EPDM dynamic wiper seals and silicone-treated pile weatherstrips. When locked in the down position, the seals compress uniformly, guaranteeing zero cold draft penetration even under severe winter wind pressures exceeding 1,500 Pa.
Modern high-rise developments along the Danube riverfront demand unitized and stick curtain wall systems (EN 13830) capable of accommodating floor-to-floor structural deflection. ALUCCO manufactures custom ODM EPDM pressure plate gaskets, mullion-transom joint sleeves, and structural glazing isolators according to precise customer DWG profiles. Every extrusion batch complies with EN 12020-2 dimensional tolerances, ensuring seamless snap-in assembly on job sites and reducing labor installation costs by up to 20%.
Logistics facilities in Senec and retrofitted apartment blocks in Košice require cost-effective yet resilient seals for UPVC vinyl windows and aluminum-clad timber windows. Utilizing Roto and STAC compatible hardware slots, our customized dual-extrusion TPE seals provide weldable corners for automated window assembly lines, helping local Slovak manufacturers achieve high production throughput without compromising thermal efficiency.
At ALUCCO, our authority as a global architectural system provider stems from rigorous quality control and engineering discipline. Every export contract for window seals and aluminum profile systems undergoes a four-stage verification protocol before shipping to Europe:
Custom OEM/ODM Tooling Advantage: Require a unique seal profile for a proprietary profile series? Our in-house matrix shop fabricates custom extrusion dies within 10 to 14 business days, accompanied by initial sample inspection reports (ISIR) and physical prototype samples prior to mass production.
Yes. All of our architectural sealing profiles and thermal break systems are manufactured to EN 12020-2 profile tolerances and meet testing requirements for EN 1026 (air permeability), EN 1027 (watertightness), and EN 12211 (wind load resistance). Complete test reports and CE compliance documentation are supplied with every shipment.
For custom profile tooling, our standard MOQ starts at 1,000 meters for trial production runs. For existing standard EPDM/TPE seal profiles, we accept consolidated orders starting at single container loads or mixed shipments alongside aluminum window profiles, pergola systems, and hardware accessories.
Our cold-climate EPDM formulas utilize peroxide curing systems enriched with specialized plasticizers. This ensures the material remains elastic down to -40°C without micro-cracking, stiffening, or losing its memory recovery upon sash opening.
Yes. We offer fully vulcanized or molded corner rings tailored to your window sash dimensions. Pre-welded corners eliminate manual corner splicing on the fabrication line, guaranteeing 100% water barrier continuity at critical lower frame junctions.
Production typically takes 15 to 20 business days following technical drawing approval. Transit from our factory cluster in Turkey to major Slovak logistics hubs (Bratislava, Košice, Žilina) via overland truck freight takes approximately 4 to 6 transit days, making ALUCCO a highly responsive supply chain partner.
