Energy efficient insulated loft ladders for Passivhaus and EnerPHit certified buildings

 

The UK government has committed to achieving a 78% reduction (against 1990) in carbon emissions by 2035. As such, achieving energy efficient buildings is becoming a very high priority for new-builds, renovation and home improvement projects alike. Furthermore, embracing a Fabric First approach and Passive House (Passivhaus) standard of building is widely considered to be key for achieving the emission reduction targets.

Choosing the right products for your building project is essential, especially when aiming to achieve Passive House or EnerPHit certification. Premier Loft Ladders are therefore pleased to offer the Designo, LWT and Klimatec 160 which are certified by the Passivhaus Institute (PHI). Also available are a a range of very highly insulated loft ladders designed for low carbon buildings.

The Designo, LWT and Klimatec 160 Passive House loft ladders are certified by the Passivhaus Institute (certs. available on request). As such, they pass the strict requirements for passive building standards. Furthermore, the Klimatec 160 has the benefit of 30-minutes fire protection and a very high load rating of 250 kg per tread.

In addition to the Passivhaus certified loft ladders, our product range includes a number of loft ladders with exceptional thermal insulation. These include the Isotec 200 and Designo DD. The Designo DD features a special hatch box with an upper cover that can be closed immediately after entering the loft. Therefore, the upper cover prevents the flow of warm air into the loft space.  As a result, this helps to lock the warmth in the building and also prevents moist air from flowing into the loft and condensing in the cold areas. Further details can be found below:

WDL sealing and insulation tape for an airtight connection between the loft ladder hatch box and the building

Enhanced insulation with WDL insulation and sealing tape…

The Roto WDL insulation and sealing tape is a patented solution to ensure an airtight connection between the loft ladder hatch box and the building.  The airtight seal helps to prevent the loss of warm air into the loft, therefore resulting in improved energy efficiency and reduced heating costs.

The WDL tape is pre-assembled to the Designo, Designo DD and Ecco loft ladders. Also, it can be ordered as an optional extra on other aluminium concertina stairs and wooden loft ladders.  Contact us for further details.

Application guides

Help and advice for choosing the right loft ladder

Insulated loft ladders – information guide and data sheet

An uninsulated home loses a large amount of its heat through the roof. Insulating your loft/attic and fitting an insulated loft hatch and ladder could therefore save you hundreds of pounds in energy costs. There are three important factors to consider when choosing an insulated loft hatch and ladder:

  1. The amount of thermal insulation provided by the loft hatch
  2. Air permeability through the loft hatch box
  3. Air permeability around the outside of the hatch box

Make sure you know exactly what to look for when choosing your new insulated loft ladder. Read our complete guide and download a copy of your insulated loft ladders data sheet.
