ECOMAX-DUO is a dual board overlay system suitable for use over ECOFILM underfloor heating. It is a dry lay system that creates a free floating subfloor that is extremely stable and is instantly ready to receive the finished floor covering. ECOMAX-DUO provides a smooth stable laying surface onto which most finished floor coverings can be fixed. This enables ECOFILM elements to be used as the underfloor heating source for a variety of floor coverings such as carpet, linoleum and luxury vinyl.
Installation of ECOMAX-DUO is quick, clean and simple. The system consists of a baseboard and a top board, each with a layer of contact adhesive. The combination of ECOFILM and ECOMAX-DUO provides a labour saving, cost effective method for heating linoleum, vinyl and carpet.

The ECOMAX DUO system consists of two self-adhesive components, base boards and top boards, which bond to each other. ECOMAX DUO is a floating sub-floor. It is not fixed to the floor below. Each layer is laid out with staggered joints and arranged so that the top boards overlap the joints in the
baseboards. Base boards are thinner and have a protective plastic film to keep the self-adhesive coating clean. This is laid facing upwards and the film is left in place until cutting and fitting is completed. The top boards are thicker and have no plastic film over the adhesive coating. They are care-fully positioned, adhesive side down, so that they overlap all the baseboard joints. It is important to check that any trimming of the top board is accurate and that the adhesive coating is free from dust or fragments before removing just sufficient amount of the protective film from the baseboards to allow the top board to be bonded in place.
The adhesive will allow adjustments to be made for accurate positioning until pressure is applied. Tapping down with a rubber mallet will ensure close contact of the adhesive coatings and produce a strong, permanent bond. Take care to position boards accurately as it is very difficult to separate them once bonded. The heating system must be switched off before installing ECOMAX DUO. If the floor finish is to be glued to ECOMAX DUO, the system must not be switched back on until the glue has set completely. Temperatures should then be increased gradually.
Instructions for Installation Over Carbon Film
ECOMAX DUO boards must acclimatise in their sealed packaging, in the room where they are to be fitted, for at least 48 hours, at a temperature of at least 18°C. Before fitting ECOMAX DUO over a carbon heating system, a polythene moisture barrier sheet must be laid. This should be of a minimum thickness of 200 microns / 800 gauge and any joints must be overlapped by at least 200mm. The joints must be sealed over their total length with a self-adhesive PVC cloth tape (Duct Tape). Refer to carbon film installation instructions.
Before starting your installation of ECOMAX DUO ensure your sub-floor is permanently dry, clean and free of dust.
* Cutting ECOMAX DUO, we recommend that you use a Retractable bladed knife or similar and a straight-edge. Score the boards two or three times and then snap along the cut. This avoids making sawdust which would prevent the adhesive from bonding correctly.
Heating System Floor Sensor Installation
Special attention should be made to the location of the floor sensor. It should be installed as close to the surface as possible and be located in an area over a heating element in order to achieve accurate control. A 5mm wide groove should be formed in the top board layer of the Heat-Pak® to take the tip of the sensor and allow the cable to run to the 50mm gap at the edge of the room where the cold tails are located. If the final floor finish is to be vinyl or similar the groove and sensor should be covered with flexible filler. Care should be taken to select filler that will not react with the floor finish.
