Scandinavian design and craftmanship are combined to deliver the industry leading energy effiency. Our patented clickFIX® technology secures that there are no thermal bridges from clickFIX® loft ladders. Because the trapdoor solely consists of high-insulating material and no wooden construction. The unique sealing also ensures air-tightness. All this allows us to achieve excellent heat insulation for your home. Our loft ladders are manufactured in Denmark and most of our timber is sourced from renewable FSC® certified forrest.
We are constantly expanding our product range and are working on technical improvements and innovations: For example, DOLLE pioneered thermal insulation and developed windproof installation solutions for loft ladders. All our loft ladders are manufactured in accordance with DIN ISO 9001 and tested in accordance with DIN EN 14975.
ClickFIX® loft ladders are comprised of three separate components, the casing, ladder and trapdoor, which are assembled using a patented click system.

We are certified and our products are manufactured and tested according to all relevant standards and regulations. The quality and reliability of our loft ladders meets the requirements of all applicable requirements. Here you will find an overview of all certificates and test certificates:
Before launching a new loft ladder, we always test them thoroughly to ensure that the loft ladders meet legal requirements, industry standards and guidelines as well as our own quality demands. Our loft ladders are subjected to many different types of tests. We test the insulation capacity U-value, we test airtightness EN 12207 and we test the loft ladder's strength, repetition testing on closing mechanisms and hinges as well as tensile testing according to EN 14975. Our loft ladders are approved up to 150 kg, but we test up to 265 kg.
Our loft ladders have the market leading U-values and are tested as a building component like doors and windows. The lower u-value, the lower heat loss. At DOLLE you can get the certificate on our tested U-values.
With the DOLLE clickFIX® loft ladders a new standard is set. You have the security that you will have no thermal bridges from the loft ladder. Because the trapdoor solely consists of high-insulating material and no wooden construction. The unique sealing also ensures airtightness. All this allows us to achieve excellent heat insulation for your home.
The unique sealing system in DOLLE's loft ladders is very important as it protects against draft and heat loss. We have developed a sealing system to ensure that the gap between the trapdoor and the frame is tight preventing draft and heat loss. Our loft ladders have been tested at IFT Rosenheim according to the highest airtight class 4 - EN 12207.
DOLLE also have a series of fire-resistant loft ladders - REI 45 which have been tested according to the new European standard. REI stands for:
R (resistance) carrying capacity during fire.
E (integrity) ability to keep flames and gases out.
I (insulation) ability to keep out heat.
The 45 minutes indicates for how long the loft ladder can withstand a fire. Hence DOLLE REI 45.
Thanks to the loft ladders low weight and patented assembly technology with click modules, clickFIX® loft ladders can also be easily installed by one person. It's simple: align casing, screw in place, click on the trapdoor and ladder section and adjust to the room height - job done! To ensure a perfectly airtight loft ladder installation. Vapour barrier is supplied with the loft ladder. This ensures an airtight connection between the loft ladder and the ceiling construction.
The loft ladder comes with a well-developed spring system making the loft ladder extra easy to handle! Some would call our loft ladder light as a feather. To provide extra comfort and safety, the loft ladder is equipped with deep anti-slip treads and a handrail. It is possible to buy additional handrail to the ladder for support on both sides! The safe way up.
