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, which is certified by the Passive House Institute, along with two highly insulated loft ladders specifically designed for Passivhaus (or Passive House) buildings; the ‘Designo DD’ and ‘Supreme DD’.

The Designo DD and Supreme DD insulated loft ladders feature 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.  This not only helps to lock the warmth in the home or building, but also prevents moist air from flowing into the loft and condensing in the cold areas.

The Supreme DD insulated loft ladder is based on the high strength yet extremely easy to operate Supreme aluminium retractable ladder. It can also be specified with a low-noise electric motor to make operation of the ladder even easier. The Designo DD insulated loft ladder is based on the beautiful Designo 3-part folding wooden loft ladder, which perfectly balances aesthetics with strength and quality.

Other energy efficient thermally insulated loft ladders…

Premier Loft Ladders offer a range of insulated loft ladders that are certified with Class 4 air permeability ratings (certified by IFT Rosenheim according to DIN EN 12207/12114), which is a measure of how well the loft ladder and hatch box assembly prevent air leakage.   Class 4 certified loft ladders include the Supreme (including standard, electric and F30 fire resistance versions), the Mini (including F30, F30 Plus and F60 fire resistant versions), the Designo, the Cadet 3, the Cadet 2, Esca 11, and the ProfiLine (including F30, F30 Plus and F60 fire resistant versions).

The Designo wooden loft ladder is certified with Class 4 air permeability ratings
WDL insulation and sealing 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.
