6 best Polish window manufacturers: Comparison and reviews
Polish window manufacturers are the natural starting point if you want to import quality European windows directly.
However, based on our clients’ experience, finding the right producer can be difficult and time-consuming. That’s why I’ve prepared a short ranking to help simplify the process and make your import journey easier.
How we evaluated Polish window manufacturers:
- Transparent pricing – to quickly get an estimate without the need for lengthy conversations
- Google reviews, portfolio – to reduce uncertainty about the manufacturers’ reliability and experience

Watch out for brand names – compare apples to apples
When researching offers and product brand names from manufacturers, be aware of how products are named.
In this comparison, what we refer to as a brand name is actually the system provider’s name. Manufacturers that assemble extrusions and glazing into windows often use their own branding, concealing the actual extrusion name from system providers.
This makes direct comparisons difficult.
We recommend learning about the European window production chain to better understand the relationship between manufacturers and system providers—because it directly impacts your profits.
