THERMAL CONSTRUCTION BOARDS
Delta construction thermal boards are made from high density polystyrene. The solid insulating center is protected by a refined cement coating, creating a tough surface designed specifically for tiling, plastering and some rendering.
The polystyrene center is a high quality thermal insulator. The lightweight compressed core provides excellent strength. The refined cement outer layer has fire resistant features. All our Delta construction thermal boards are ideal for use with underfloor heating and wetrooms and are suitable for internal and external projects.
Available in the following thicknesses:
6mm, 10mm, 12.5mm, 20mm, 30mm, 40mm, 50mm, 60mm and 70mm
BESPOKE SHOWER TRAY
Our Delta bespoke design drain trays are designed to create a “walk-in” easily accessible shower area. Much like our Delta construction thermal boards, our bespoke drain trays are also made from high density polystyrene with a refined cement coating, creating a tough surface designed specifically for tiling and other applications.
The Delta bespoke drain trays can be easily trimmed to suit specific measurements if needed.

LINEAR DRAIN TRAYS
Delta Linear Drain Trays
Our Delta linear design drain trays are designed to create a “walk-in” easily accessible shower area. Much like our Delta construction thermal boards, our linear drain trays are also made from high density polystyrene with a refined cement coating, creating a tough surface designed specifically for tiling and other applications.
The Delta linear drain trays can be easily trimmed to suit specific measurements if needed.

OFFSET DRAIN TRAYS
Delta Offset Drain Trays
Our Delta offset drain trays are designed to create a “walk-in” easily accessible shower area. Much like our Delta construction thermal boards, our offset drain trays are also made from high density polystyrene with a refined cement coating, creating a tough surface designed specifically for tiling and other applications.
