At a glance: roof windows and skylights from Poland
- 🏭 Global manufacturing hub: Poland is home to some of the world's largest roof window manufacturers, supplying loft and attic glazing to markets across Europe and beyond.
- 📐 Sizing is standardised, fitting is not: roof window formats follow common European sizing codes, but flashing kits must match your specific roof covering.
- 🌬️ Airtightness matters most: the insulation collar and internal finishing kit determine long-term performance as much as the window unit itself.
- 🚚 Fragile, high-value cargo: roof windows travel in dedicated crating and need careful handling to avoid glazing and frame damage in transit.
Why Irish buyers are sourcing roof windows from Poland
Following on from our recent guide to roofing materials, roof windows and skylights are one of the most requested follow-up items from Irish contractors converting attics and finishing loft spaces. Poland's roof window industry supplies a huge share of the European market, giving Irish buyers access to a wide range of formats, glazing specifications and price points directly from factory.
The products themselves are well engineered and widely trusted. The value Actitrade adds is in getting the specification, flashing kit and delivery right the first time — a mismatched flashing kit or the wrong insulation collar can turn a straightforward loft conversion into a leak risk.
1. Choosing the right roof window specification
- Glazing: double or triple glazing, with U-values that should be checked against Irish nZEB requirements for habitable roof spaces.
- Opening type: centre-pivot for general use, top-hung for low-level access, or fixed units for light-only applications.
- Size code: confirmed against the rafter spacing on your specific roof, not assumed from a catalogue default.
- Finish: timber, laminated or PVC-coated frames, depending on the interior finish and moisture exposure of the room.
2. Flashing kits and insulation collars
A roof window is only as weathertight as its flashing kit, and flashing kits are matched to the specific roof covering — flat tile, profiled tile, slate or metal sheet all require a different kit. Ordering the wrong flashing type for your roof covering is one of the most common and most disruptive mistakes on a loft conversion.
The fix: confirm your roof covering type and pitch before ordering, and pair the flashing kit with the manufacturer's dedicated insulation collar to maintain a continuous airtight and thermal line around the window opening — the same principle covered in our earlier guide to XPS and airtightness detailing.
3. Transport and site handling
Roof windows are glazed units and travel on dedicated crating, usually with the flashing kit and insulation collar packed separately. Confirm with your supplier or logistics partner that units are crated upright, edge-protected, and that crates are clearly marked for careful handling at every stage of a multi-leg delivery to Ireland.
| Element | What to specify | Why it matters |
|---|---|---|
| Roof window unit | Glazing spec, opening type, size code | Matches performance and fit to your roof structure |
| Flashing kit | Roof covering type and pitch | Prevents leaks at the window-to-roof junction |
| Insulation collar | Manufacturer-matched to the window model | Maintains airtightness and avoids cold bridging |
| Transport | Upright crating, edge protection | Reduces risk of glazing and frame damage in transit |
