The Project Timber Evolution Cedar Insulated Garden Room

If you are planning to use your building more frequently and have furniture items to add, then an 11mm floor is a more solid choice. It is constructed with engineered interlocking boards, giving you a stronger floor to walk on and store items. Our tongue and groove floors come untreated but with pressure treated joists as standard.

If you will be having heavier items, such as storage shelves and sofas, then a 19mm tongue and groove floor will support all of your items. The tongue and groove floor is untreated but comes with pressure treated joists to make them more resistant to ground moisture.

For the ultimate heavy duty floor, choosing our 28mm thickness will give you an extremely solid and extra durable floor which you can store heavy items, such as gym equipment and large furniture items. The 28mm thickness also offers superior strength and rigidity and is strong enough to support the weight of a van driving over it!
