Fit-From-Below Systems

Our Fit-From-Below system makes installing underfloor heating on joists simple. Often used in renovations and on first or second floors. It doesn’t raise the floor height and no screed is required. Perfect for fitting between joists on any storey.

The aluminium sheet allows for a more even heat distribution.

This system provides the opportunity to install underfloor heating to upper floors when renovating the room below and the joists are exposed.

What’s unique about the Fit-From-Below system?

The Fit-From-Below Heat Plates are specifically designed to sit between joists from below and due to the fact that they are single-tile J plates, they benefit from being able to be fitted in any joist width, making them extremely versatile.
