Install a retractable attic stairs

The installation of a loft ladder is relatively easy to implement due to the wide range of prefabricated stairs. Sliding models or concertina folding staircases are used as standard technical functions. The attic stairs must be mounted on a sturdy flap and must be thoroughly sealed.

Preparation and calculation

Who wants to install a loft ladder, must first decide on a model and measure the height to be bridged, taking into account the climbing angle. When calculating the stairs, the information provided by the manufacturers, which are based on the legal standards and regulations, help. In addition, the dimensions for the required stair opening are specified, the feasibility of which must be checked.

As a floor staircase for sinking a sliding staircase or a scissor staircase to choose from. When installing a push-in staircase, a model with spring technology or a variant that can only be moved by hand can be selected. A scissor stair is usually provided with a spring technique.

Insulation and insulation

Great attention is to be paid to the insulation of the attic stairs. The stairwell in the ceiling to the attic offers a risk of permanent heat loss. In order to sufficiently insulate an attic staircase, the flap or hatch must prevent surface heat dissipation. In addition, there are thorough bearings of the flap edges in the bottom opening to avoid cracks and joints. Ideally, the attic stairs are completely airtight when closed.

If the hatch or hatch does not have the necessary strength and texture to prevent heat loss on a flat surface, insulation boards can be mounted on top of which the prefabricated staircase is then mounted. The installation of a push-in staircase and a scissor staircase usually differs only with respect to the tensioning of the spring to complete the installation.

To install a loft ladder

  • Wooden strips for frames
  • Screws and dowels according to ceiling conditions
  • Insulating boards (e.g., Styrofoam) and glue
  • wood screws
  • Two hinges with fixing screws
  • Locking pin lock with fixing screws
  • Dämmkrepp
  • drilling machine
  • Cordless Screwdriver
  • spirit level

1. Set the frame

Dress all four inside edges with wooden strips that form a stable screwed box for later mounting the stairs.

2. hinges and lock

Screw the hinges and the lock lining of the lock to the appropriate places on the frame. Pay attention to the correct opening direction.

3. Damp the hatch

If necessary, apply an insulating layer to the top of the hatch. Remember recesses for the hinges and the pin lock.

4. Mount the stairs on the hatch

Attach the prefabricated staircase to the hatch as specified by the manufacturer.

5. Insert hatch

Insert the hatch open and screw the open hinge wings already mounted to the frame.

6. Insulate edges

Stick the bearing edges, on which the closed hatch presses, with elastic insulation crepe.

7. Tension the spring

If necessary, follow the manufacturer's instructions.

Tips & Tricks

Build a guard rail around the hatch opening in the loft, leaving only the entry side open. The railing protects against accidental fall into the stairwell.
