System Summary

The Alreflex ZebraFloor system is a simple and cost-effective R1 classified insulated beam and block flooring system that is made up of 2 main components.

Alreflex ZebraFloor Infill Planks – Unique EPS planks that fit between flooring beams that have a layer of Alreflex bubble foil is bonded to the underside to improve thermal performance.

Alreflex ZebraFloor Top Sheet – High-performance EPS boards designed specifically with the thermal resistance and strength required in this application.

U-Values

About System

The Alreflex ZebraFloor system provides an extremely cost effect way to achieve low U-values in beam and block floor constructions. This is achieved by replacing the concrete blocks with Alreflex ZebraFloor Infill Planks to provide insulation and form work. This is then covered by a high performance ZebraFloor Topsheet followed by a structural concrete topping.   

Alreflex ZebraFloor Infill Planks 

By combining high performance EPS with our Alreflex bubble foil insulation we have created a thermally efficient, lightweight insulation that is ideal for use in beam and block construction. 

The Alreflex ZebraFloor system has been designed to be as efficient as possible. Each plank is 1200mm long, the equivalent of more than five standard concrete blocks, making installation very quick and simple. The planks are 440mm wide, this means that there is no need to change any existing beam designs and their square edges make them suitable for use with all major beam suppliers. 

The Alreflex bubble foil insulation found on the underside of the infill planks improves the systems thermal performance while maintaining the ease of installation.  

ZebraFloor Topsheet 

This high performance EPS insulation has excellent thermal and compressive strength performance. It is available in a range of thicknesses, allowing low U-values to be achieved while maintaining a thin overall floor construction.  

ZebraFloor Topsheet is also available in two compressive strength variants, Topsheet 120 and Topsheet 200. ZebraFloor Topsheet 120 designed for normal domestic loads, while ZebraFloor Topsheet 200 is projects where higher than normal loading is expected. A structural engineer should always be consulted when specifying this type of product. 

ZebraFloor boards are UKCA marked and tested to BS EN 15037-4. 

Environmental 

The EPS used in these products is recyclable and has a BRE Green Guide A+ environmental rating. No blowing agents are used in the production of ZebraFloor products and they have an Ozone Depletion Potential (ODP) of zero and a Global Warming Potential (GWP) of less than 5.
