How many Do I Need ?

How many Loft Storage Stilts you need depends on a number of factors :-

The size of the Loft Storage platform you want to create
The type of the loft boards you use .
the distance between your loft joists.

1. The Size of the Loft Storage Platform

This will depend on how much stuff you have to store , remember building regs recommends only 25kg of storage for every m2 of the loft storage platform.

The larger your loft the bigger the area you can board.

2.The Type of the loft boards you use.

There are two main types of loft boards :-

Loft boards sold in a pack of 3
These are most common used they are 1.2m * 300 m * 18mm in size and are easier to handle and actually carry into the loft through the loft hatch especially if you have a small loft hatch
These are also sometimes called chipboard sheets or loft chipboard sheets.

Flooring grade loft boards which are 22mm plus in thickness sold in single sheets

These are much longer 2.4m * 300mm * 22mm thick
These are only usually used by the trade, because of the size and weight of these it is very difficult to actually get them into the loft through the loft hatch and are only really used by professional loft boarding companies

3. The distance between your loft joists.

Most lofts in the UK and Ireland are either 400mm spacing or 600mm spacing Loft Storage Stilts will work for both .
for the very small number of lofts with different spacing Loft Storage Stilts will still work but you will need different amounts not in our tables below.
