37" x 46" FWU-L Egress Roof Window - Tempered Glass – Fakro 

Accessing the roof and maintaining adequate natural light shouldn't be a challenge. Unfortunately, traditional solutions often provide either access or daylight, rarely both effectively. The 37" x 46" FWU-L Egress Roof Window by Fakro solves these problems by combining easy roof access with generous natural lighting. 

The FWU-L features a strategically positioned handle halfway up the sash, making operating even in tight spaces effortless. With its ample glazed area, this window transforms dark attics into bright, welcoming spaces. It also provides straightforward roof access for maintenance or inspection needs. 

Why Should You Use the 37" x 46" FWU-L? 

  • Maximize Natural Light: The window's generous daylight area brightens every corner, minimizing the need for artificial lighting. 
  • Easy Access: Its thoughtfully positioned handle ensures smooth operation for routine roof maintenance 
  • Flexible Installation: The FWU-L is compatible with roof pitches between 15-55 degrees, adapting to most architectural designs 
  • Energy Efficient: Low-emission and heat-reflecting double-glazed glass helps maintain comfortable indoor temperatures 
  • Weather Resistant: The internal gasket system effectively manages condensation, protecting your interior.
