CE Marking


We are excited to share that we've successfully completed the window tests for CE marking in the final week of our two-month Korean Startup Centre onsite program in Finland. ✨️🎉

The window specimen features a timber frame, triple glazing, and a UBLO circular window insulated with aerogel.

This is our first European trial, but we have already conducted two trials in Korea, so the results were excellent as expected. It also meets local Finnish window performance standards. The test results are as follows:

→ Airtightness (EN 12207) Class 4 (highest glass)
→ Watertightness (EN 12208) Class E1200 (75min 1200Pa; better than the highest class)
→ Wind pressure resistance (EN 12210) Class 4 (P3 3500 Pa; better than the highest class)
→ Thermal insulation (EN 10071-1, EN 10077-2, EN 673) Uwindow set≤0.87 W/m2K; Ucircular window≤0.95 W/m2K
→ Sound insulation (EN 10140-1, EN 717) Rw= 36 dB

UBLO window can be now approved for use in projects and is available for sale across Europe!

We would like to express our sincere gratitude to all our collaborators involved in the tests and to the KSC program organizations for their support throughout this process.
