Loft Ladders for Passivhaus Projects

Loft Ladders for Passivhaus Projects

The drive towards cutting emissions and the enhanced focus on sustainability means buildings constructed to Passivhaus standards are becoming increasingly popular. Choosing the right products for these building projects is essential, especially when aiming to achieve Passivhaus certification.

Premier Loft Ladders offer three loft ladders that pass the strict requirements for passive building standards and are certified by the Passivhaus Institut; the Designo, Klimatec 160 and LWT.

They are designed to offer high thermal insulation and an airtight seal. However, what differentiates them from other loft ladders are the extra steps that have been taken to minimise thermal bridging.

Their entry-level passive house loft ladder is the LWT, which features a folding wooden ladder and is available in a range of standard sizes. It boasts an impressive U-Value of 0.51 W/m2K.

The Designo is supplied made-to-measure to suit a wide range of aperture dimensions and ceilings heights of up to 3.3m. It also has an innovative 6-point locking mechanism for a window-tight seal all the way around the hatch, as well as a patented sealing and insulation tape pre-assembled to the outside edges of the hatch box, which offers an airtight seal with the building.

For more demanding situations, the Klimatec 160 offers not only superb thermal insulation and an airtight seal, but it also benefits from 30-minute fire protection.

Furthermore, the high strength steel ladder is finished in a durable powder-coat and is rated for up to 250 kg per tread. As such, the Klimatec 160 is an ideal solution for commercial and industrial use.
