Silva Joisted Floor System is installed in many refurbishment projects. Joists traditionally tend to be installed at 400mm centres. However, we can supply a more bespoke system to suit individual properties with varying joist centres as required.

The Silva Joisted Floor System is suitable for almost any floor finish, in particular where the flooring is wood or engineered wood.

When using tiles as the final floor finish, additional layers of plywood or tile backer board may be required to create a rigid base.
