Suitable for Refurbishments and All Floor Types

The Silva Joisted Floor System is recommended for refurbishment projects featuring a traditional wooden joisted construction.

The heating pipes are installed between floor joists and on top of The Clypso System’s Insulation Panels. The Silva Joisted Floor System is suitable for almost any floor finish, in particular where the flooring is wood or engineered wood.

For Installation between Timber Joists

The system requires the battens to be securely installed by a flooring contractor and whilst joists tend to be installed at 400mm centres, we can supply a more bespoke system to suit individual properties with varying joist centres as required. After successful installation of the insulation between the joists, a thin layer of screed is applied.

Although the system is suitable for most flooring finishes, when using tiles as the final floor finish additional layers of plywood or tile backer board may be required to create a rigid base.
