To eliminate any potential problems with wiring or insulation use two by four or two by six lengths to create a subfloor system for the new decking.
Adding plywood to attic.
Adding a floor to an attic can increase storage space or create a new room.
Two shelves made of 1 x 4 lumber with plywood decking and leaving some open space below work out to be just about ideal for storing most household goods.
Attic flooring consists of materials as basic as sheets of plywood as well as more elaborate interlocking floor systems.
But if the floor is covered in plywood you can t stuff enough insulation beneath it to do the job sufficiently not even in warm climates.
Install two by four blocking between joists or wherever needed to support edges of the plywood that do not have support from the bottom.
It might seem impossible to haul it up to the attic.
Adding shelves around the perimeter of the room is a lot of work but can make it much easier to organize your things in the attic.
Plan to pull up the flooring and layer new insulation on top of the old.
To properly add an attic storage deck start by measuring the largest area available that is not hindered by any ductwork.
To make the job easier use a circular saw to cut the plywood sheet first into 2 2 8 strips which will be much easier to handle.
Then you ll need to build a grid like structure that can hold up the plywood flooring.
If your attic joists won t bear the weight necessary to finish out a living space but the engineer cleared them to support floor decking for light storage you can install inch plywood or.
The solid base allows you to store items in the attic as well as to walk.
While this is not the optimal setup it is acceptable to have ceiling joists covered with plywood or osb to use for light attic storage of dead loads.

In attics built purely for storage purposes you may find 2x6 ceiling joists or in some cases even 2x4 joists.
Stop using your attic for storage.
Plywood comes in large sheets.
Maneuvering heavy 4 x 8 sheets of plywood or osb oriented strand board up to an unfinished attic is sometimes like trying to fit a square peg into a round hole.
And preferably can avoid any existing roof support.
Because the simplest and cheapest way to insulate an attic is to add material to the floor.
