• Step 1

Clear work Area

You only need clear a small area, by placing items already in the attic to one side. There's no need to remove items from the attic altogether, as you can build the deck in stages and put items back on to an area you’ve completed. Insulate between the joists if it's not already been done, but temporarily roll back any insulation, or move aside blown insulation that sits over the joists (this will be put back later). Make sure you have all your tools ready – you only need a tape measure, an electric drill and the screws that are supplied with the StoreFloor kits.


  • Step 2

Arrange Tri-Supports

Align the Tri-Supports along the joists, avoiding obstacles and spacing them 24 inches apart. Screw the supports into the joists through the two pre-drilled holes.


  • Step 3

Slide on steel beams

Slide the galvanised steel Cross-Beams on to the supports and secure them through the pre-drilled holes and slots. The sliding nature of the Cross-Beams gives you adjustment in case your joists are unevenly-spaced apart. There is no need for the Cross-Beams to meet exactly in the middle.

If you're going to lay StoreFloor close to the edge of your attic space, then you may not have enough room to slide on the final Cross-Beam. In this case, just assemble the final set of Cross-Beams on to the Tri-Supports (without screwing anything in just yet) before placing the latter on to the joists, then lift them all up as one sub-assembly into place.


  • Step 4

Fit the Uni-Supports

Simply slide each Uni-Support underneath the Cross-Beams and secure them with a screw through a slot in the top of the Cross-Beam, and another through the hole in the foot of the Uni-Support into the joist. In our standard kits, we supply one Uni-Support for every Cross-Beam.


  • Step 5

Add the full depth of insulation

Now add the extra level of insulation above the joists, by rolling out the recommended depth of insulation or adding the required batts or loose fill material.The supports can be used as a guide so you know how deep the insulation should be


  • Step 6

Secure attic flooring deck

Secure the deck by screwing the attic flooring boards into the top of the Cross-Beams
