Download UFH PLANK Details / Specs
The Warmwood UFH Plank has been specifically designed for use with under floor heating and has been tested and certified by the German EPH authorities for this purpose.
EPH stands for ( Entwicklungs- und Prüflabor Holztechnologie ) which means ( Development and testing laboratory of Wood Technology ).
All details on the EPH certificate can be found at ( www.eph-dresden.de )
THE EPH TEST
The test by EPH is very demanding and provides our product with a certificate for suitability of use with UFH (under floor heating) applications and shows that it meets specific industry standards with regards to the following:
1: Determination of bonding quality
This procedure is carried out by firstly soaking the Warmwood UFH Plank for 2 hours in a water bath at 70 degrees C then drying the Estrato Plank in an oven at 60 degrees C for a period of 3 hours.
2: Determination of the resistance to changing climates
This procedure is carried out by bonding the Warmwood UFH Plank to a underfloor heating panel of 1200mm x 1200mm using an appropriate adhesive then putting it into a climatic chamber for the following test at a water flow to surface temperature of 23 degrees C.
1 week at 50% Rh
1 week at 65% Rh
1 week at 85% Rh
1 week at 30% Rh
This tests for the following:
Average opening of short side joints
Maximum opening of short side joints
Average opening of long side joints
Maximum opening of long side joints
Height difference of short side joints
Maximum height differences of short side joints
Height differences of long side joints
Maximum height differences of long side joints
Average flatness over panel width
Maximum flatness over panel width
THE MANUFACTURING PROCEDURE
The procedure for making our Warmwood UFH Plank 2.5mm veneered floor is very different from that of a normal engineered floor board and involves the techniques employed within the hardwood veneering industry.
The Oak is boiled in water then dried at 130 degrees C to produce ultra stable 2.5mm veneers of the highest quality.
Next we glue press the 2.5mm veneers to the finest quality birch ply at 100 degrees C.
The boards are then put through our bespoke manufacturing line to be profiled and end matched to exacting standards with a surface to surface tolerance of less than 0.02mm.
The result is a plank that can withstand the variations in temperature and humidity in a wide range of commercial or residential applications due to its in built stability.
This unique procedure that we employ for manufacturing our Warmwood UFH Plank is normally only used for producing veneers for the furniture industry and hence this is the only production method using a real wood surface for engineered flooring that can guarantee a wide flooring board against the following problems that have now been found to be associated with engineered flooring.
Our Warmwood UFH Plank will not have the possibility to move due to the adverse effects of moisture or humidity levels, causing expansion of the Oak surface witnessed by the board becoming crowned due to the exceptional proportional strength of the Oak surface acting upon the birch plywood substructure.
Our Warmwood UFH Plank will not be adversely effected by excessive heat which may cause contraction of the oak when bonded to the plywood resulting in Fischer cracking to become present in the surface of the boards.
Our Warmwood UFH Plank will not suffer from delamination of the surface from the substructure due to the the excessive forces of expansion and contraction resulting from seasonal change and climatic effects.
