Passive House Certified Loft Ladder

The Passivhaus Institute has awarded the Designo wooden loft ladder certification for use in passive buildings.

The Designo features the latest innovations in loft ladder design to perfectly balance aesthetics with performance. It offers excellent thermal efficiency (U value 0.60 W/m2K) and an airtight seal (class 4 certified) thanks to a highly insulated trapdoor with 6-point locking mechanism.

The Designo also benefits high strength performance; rated to 180kg per tread. This makes it ideal for demanding projects. Furthermore, it features concealed hinges and a discrete, recessed operating latch. The result is a high quality, seamless finish.
