Water proofing

For water proof construction all joints, penetrations and fastener locations must be treatedby approved polyurethane water proofing agents as per manufacturer's recommendation.

Brick and concrete walls

Even walls procedure

- For clean and sound wall use flexible tile adhesive. Coat the wall surface or apply an adhesive directly to the board surface (min. thickness 10 mm) - Comb out with 10 mm trowel creating a ribbed adhesive bed. Offer up boards and align vertically and horizontally. Bed firmly into place. - If adhesion can not be achieved by adhesive use dowels, screws and washers at the rate of 5 dowels per m . Use min. 20 mm boards. - Cover all joints with fiber glass tape embedded in flexible tile adhesive.

1.5 Marmox XT: Phenolic Foams®

Marmox XT differs from standard Marmox Board in that the core material is made of a specially selected type of phenolic foam instead of XPS.

The main advantages of Marmox Board XT in comparison to the XPS type are the considerably better heat insulation values, the non-combustible fire safety and higher continuous working temperatures (more than double) and the considerably higher resistance to fire and high temperatures.

On the other hand, the XPS type usually has lower water absorption properties. However, Marmox Board XT has comparable water absorption when using an additional surface waterproofing.

Marmox HD boards differ from standard construction boards in that they are strengthened with regularly distributed polymeric concrete prismspassing through the total thickness of the board. The diameter of the prisms range between 10 to 30mm. They are spaced at distances of 25 to 100mm in both directions. The main advantage of the Marmox HD board is its high compressive strength which varies between 4 and 24 Kg / cm at a negligible compressibility compared to the standard Marmox board.

Compared to the standard type, Marmox board HD doesn't show a significant decrease in heat insulation or weight increase.

Installing Marmox Board under-floor heating insulation

Whatever the construction of your subfloor, our under-floor heating insulation will be sure work with it. The system can be installed on both concrete and timber floors.

Fixed with adhesive Procedure:

- Make sure the floor is clean and dirt free.- Using a floor trowel comb a thick bed of cement based flexible tile adhesive over the floor.- Lay Marmox Board down in place and press firmly. Stagger all the joints in a brick like fashion. Tape the joints with Marmox reinforcing tape. For extra waterproofing you can use Marmox acrylic sealant over or between the joints. Or for really wet areas use Marmox self-adhesive waterproof tape.- The under-floor heating system can then be simply rolled out and fixed according to the manufacturer's recommendations and is then ready for tiling.

®

Fixing with screws and washers Procedure:

- Make sure the floor is clean and dirt free. - Use 12 stainless steel screws / Marmox washers per 1.25 m board (3 rows or 4). Secure the Marmox Boards tightly to the floor, ideally in a brick like fashion. - Tape the joints with Marmox reinforcing tape. For extra water proofing you can use Marmox acrylic sealant over or between the joints and over screw holes. For really wet areas use Marmox self-adhesive waterproof tape.
