The "Thermo Extra" is a traditional folding attic ladder which folds in three parts. This differs from the "Thermo" because the trapdoor is twice the thickness, giving you twice the amount of insulation.
The trapdoor of the Thermo Extra is constructed using the same sandwich method as our standard model, but with this “Extra” model the door is 46 millimetres thick, meaning you get twice the insulation for even less heat loss. The same d-handrail is also fixed to the top third of the ladder section, and there are also protective rubber feet on the bottom of the wooden ladder. The trapdoor is spring loaded, meaning you do not have to take any weight while pulling it down and it makes it easier to close up as the springs take most of the weight.
The timber used in the making of this attic stairs is FSC environmentally rated, this means it has only been supplied by responsible sources. This ladders trapdoor minimises heat loss, which in turn can reduce consumption, making it even more kind to the environment.
The "Thermo Extra" is an excellent choice for people trying to achieve a high building energy rating (B.E.R.) on their home. If you are attempting to build an "Airtight" home, you can be confident in the fact that this attic stairs is you best option as we take care to seal all around the opening by using chalk sealant around the architrave and on request we can also use airtight tape under the architrave. This ladder has a certified class 4 airtight hatch. The latest model now has a second airtight seal added.
