Energy efficient insulated loft ladders for Passivhaus buildings…

 

Achieving energy efficient buildings is becoming a very high priority for new-builds, renovation and home improvement projects alike. Premier Loft Ladders are therefore pleased offer the Designo loft ladder and Klimatec 160, which are both certified by the Passive House Institute, along with two highly insulated loft ladders designed for passive and low carbon buildings; the Designo DD and Supreme DD.

The Designo and the Klimatec 160 are both certified by the Passivhaus Institut (cert. available on request). As such, they pass the strict requirements for passive building standards. Furthermore, the Climatic 160 has the benefit of 30 minutes fire protection and a very high load rating of 250 kg per tread.

The Supreme DD insulated loft ladder 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. In addition, upper covers are available for the Designo (Designo DD) and the Klimatec 160.

More insulated and airtight loft ladders…

Premier Loft Ladders offer a range of insulated loft ladders that are certified with Class 4 air permeability ratings. As such they prevent air leakage through the loft hatch and help keep in the warmth. Class 4 certified loft ladders include the Supreme (including standard, electric and F30 fire rated versions), Ecco, MiniLine (F30, F30 Plus and F60 fire rated), Designo, Quadro, Cadet 3, Esca 11, and the ProfiLine (F30, F30 Plus and F60 fire rated).

The Designo wooden loft ladder is certified with Class 4 air permeability ratings
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 Columbus 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 Supreme DD 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.
