Hatch box

Written by admin on . Posted in Stair dictionary. No Comments on Hatch box

Professionals refer to the rectangular frame of loft ladders, which is installed in the ceiling and in which the staircase remains when folded in, as a hatch box. The length and width of the hatch box must match the dimensions of the ceiling opening. In addition, when buying an attic staircase, you should choose the height of the hatch box according to the measured ceiling thickness. Hatch boxes can be made of wood or MDF. For many hatch boxes, Minka also offers a matching top cover that increases thermal insulation.

Rotation per step

Written by admin on . Posted in Stair dictionary. No Comments on Rotation per step

The rotation per step is about the angle at which the steps wind around the centre pillar of a spiral staircase. If the rotation per step is high, it means that the steps are comfortable to walk on. On the other hand, if the angle of rotation is smaller, less space is required for the stairs.

Fire-retardant EI30/EI60

Written by admin on . Posted in Stair dictionary. No Comments on Fire-retardant EI30/EI60

According to ÖNORM, the fire-retardant effect of materials is divided into several classes. EI230 and EI260 also belong to these fire resistance classes. The number in the designation indicates the minimum time the material can withstand a fire. For example, if a loft ladder is labelled EI260, it means that the staircase will prevent a one-sided fire from spreading further for at least 60 minutes. Fire-retardant attic stairs therefore save valuable time during rescue from a possible fire.

Attic staircase

Written by admin on . Posted in Stair dictionary. No Comments on Attic staircase

Attic staircases are stairs that lead to unoccupied attics or storage rooms. They are usually fixed in the ceiling and only folded out or extended when needed. Attic stairs can be made of wood or metal. A special form of metal attic stairs are so-called scissor stairs, which are pulled out like an accordion.

Staining

Written by admin on . Posted in Stair dictionary. No Comments on Staining

Staining is the application of a chemical solution (stain) to the surface of wood. This changes the colour of the wood, but the natural grain remains. The walnut steps of the Minka stairs are not made of real walnut wood, but of beech wood that has been stained to a walnut look. For additional protection of the wood, our stair treads are also coated with a high-quality layer of varnish.

Outdoor staircase

Written by admin on . Posted in Stair dictionary. No Comments on Outdoor staircase

All stairs marked with the term outdoor staircase are suitable for outdoor use. The metal parts of these stairs are galvanised and therefore extremely resistant to environmental influences of all kinds. They do not rust even in wind and weather. It is important to choose a suitable foundation for outdoor stairs. However, Minka outdoor staircases can of course also be used indoors.

Landing

Written by admin on . Posted in Stair dictionary. No Comments on Landing

Landing is the distance that a staircase needs from the rearmost point to the foremost point. The landing is therefore a measure of how much space a staircase requires. However, it should be remembered that space is also required in front of the first step in order to be able to climb the stairs comfortably.

Fold-out space

Written by admin on . Posted in Stair dictionary. No Comments on Fold-out space

The ladders of many attic staircases consist of several parts that are connected to each other via hinges. To be able to use the stairs, the ladder must be folded out. This requires a certain amount of space at the front, which should be taken into account when planning an attic staircase. This additional space required is also known as fold-out space.
