EUROPEAN STEEL WINDOWS
Steel windows are fixed or opening window frames built from slender steel profiles — known for ultra-slim sightlines, large glass surfaces, and a distinctive industrial or loft aesthetic that aluminium and PVC cannot replicate. Icon Loft manufactures custom steel windows to order in our factory in Wrocław, Poland, supplying B2B to dealers, contractors and architects across the UK, Netherlands, Germany, Belgium and the US. Average production lead time: 10-12 week from deposit to dispatch.
Fabrication lead time of 10-12 weeks

from deposit payment to goods ready for shipping from our warehouse in
Wrocław, Poland. This includes shop drawings and approval.

Why dealers choose steel windows from Poland
Why dealers choose steel windows from Poland
Poland is Europe’s largest exporter of steel windows and doors.
Icon Loft manufactures exclusively for B2B — we do not sell direct
to consumers or compete with our dealers in their local markets.
What this means in practice:
Factory direct pricing — no distributor margin added. You buy at
manufacturer prices with dealer discounts based on volume.
White label — we do not disclose that we are your supplier. Your
client sees your brand, not ours.
Weekly consolidated shipping — we run fixed weekly routes to the UK,
Netherlands, Belgium and Germany. Your orders travel with other
partners’ orders, keeping freight costs low.
Online configurator — registered B2B partners quote steel windows
24/7 with real-time pricing. Average time saving: 65% per quote
versus email back-and-forth.
No minimum order — start with a single window. We produce to order,
so you carry no stock risk.

FAQ
Frequently asked about steel windows
Steel profiles split by an insulating barrier to reduce heat transfer while keeping slim frames; verified by EN 14351-1 in EU and NFRC methods in the U.S.
Yes, when the product carries NFRC ratings aligned with local IECC adoption; verify climate zone targets before ordering.
System literature ranges from ~0.8–1.5 W/m²K (Uw) depending on system/IGU/size; NFRC U-factors will differ by unit size and frame/glass ratios.
Plan 7–8 weeks fabrication (2024 average 41 days to RTS) + ocean freight; door-to-port ~10–12 weeks with clean paperwork.
Jansen, Ottostumm, RP Technik—each publishes performance classes and thermal data.
Yes—interior and thermally broken exterior steel doors to keep
Steel windows are window frames manufactured from slender steel profiles, offering ultra-slim sightlines and large glass areas that aluminium and PVC cannot match. They are used in loft-style interiors, heritage buildings, commercial spaces and high-end residential projects. Available as fixed, casement, pivot, awning and tilt-turn configurations.
A thermally broken steel window uses a layer of insulating material — typically glass-fibre reinforced polyamide — inserted between the interior and exterior steel halves of the profile. This breaks the thermal bridge, reducing heat loss while keeping the characteristic slim steel frame. Required for exterior applications in most European building regulations.
We manufacture using Jansen Janisol, Jansen Economy 50, and Ottostumm W40 profile systems — all European-certified thermally broken systems with documented performance data, CE marking, and full technical documentation available for architects and building control.
Our average production time is 42 days from deposit to dispatch — including shop drawings and approval. UK and European delivery adds 3–5 days via weekly consolidated road freight. US delivery adds approximately 20–45 days ocean transit.
All steel windows are fully bespoke — there are no standard sizes. Typical width per sash: 400–1,200 mm. Typical height: 600–3,000 mm. Multi-sash configurations and fixed light combinations are available in any dimension within structural limits.
Yes — we manufacture steel windows and steel doors from the same profile systems, ensuring matching sightlines, finishes and hardware across a project. This is a significant advantage for architects specifying whole-building fenestration packages.
System performance ranges from approximately 0.8–1.5 W/m²K (Uw) depending on profile system, glazing unit specification, and window size. Full thermal data is available per system on request.
Yes — we run weekly consolidated shipments to the UK. All export paperwork is handled by us. We have supplied UK dealers and contractors since 2022 and are familiar with UK building regulation requirements.
