Designo: the Passive House certified loft ladder

Designo: the Passive House certified loft ladder

The innovative and beautiful Designo from Premier Loft Ladders is now certified by the passive house institute.

The high specification Designo wooden loft ladder offers excellent thermal insulation and a class 4 certified airtight seal. It is therefore no surprise that it has been certified by the Passive House Institute for use in passive buildings. The passive house certified version of the Designo benefits from modifications designed to further reduce the risk of thermal bridging.

As a result of high quality materials and the latest innovations in technology, the Designo offers reduced heat loss without compromising on aesthetics. As can be seen in the thermal map, the Designo’s trapdoor is just 620mm thick. In addition, the insulating material is concealed behind durable white panels.

The Designo passive house certified loft ladder continues to offer high strength performance. This is because the load of the ladder and its occupant is directly carried by the hatch box (rather than the trapdoor). It is therefore rated to 180kg per tread, with an overall load of 420kg/m2. This makes it ideal more demanding residential projects, as well as some commercial/industrial applications.

Furthermore, the Designo features concealed hinges and a discrete, recessed operating latch. The result is a high quality, seamless finish.
