PlankCo UFH Plank has been specifically designed for use with under floor heating and has been tested for this purpose.
THE MANUFACTURING PROCEDURE
The procedure for making our PlankCo 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 PlankCo 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 PlankCo UFH Plank has exceptionally little movement when subjected to the adverse effects of moisture or humidity levels, normally 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 PlankCo 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 PlankCo 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.
How do we make those veneers and why are they different to normal 4-6mm top layer.
First we select veneer quality logs
We then submerge the logs is tanks of boiling water and boil for a period of 4 days.
We then slice the logs into 2.5mm veneers
The veneers are the dried at 130 degrees
The veneers are then cut to width and bonded to the finest quality Scandinavian Birch Ply in a heated press firstly at 100 degrees for a period of 5 minutes and then at 20 degrees for 5 minutes
This whole procedure closes the cells of the oak and thus limits the hygroscopic effect e.g. its ability to absorb or give off moisture, the result being a board surface that will not move due to excessive climatic changes.
Normal 4-6mm surface layers are dried in a kiln for around 3 weeks at 60 degrees the cells remain open and working and hence will always have movement.
The engineered floor board in its current form was a creation that was developed from the world of veneering.
It is commonly believed within the flooring industry and end users alike that engineered boards in their current most commonly manufactured form are a fool proof solution to the need for a wooden floor in a commercial or residential setting, and that the effects of climatic change will have no drastic effect on the engineered board in comparison to the use of employing a solid board for the same installation.
But this is where they are very mistaken and wrong and it seems that the great majority of architects, interior designers, wholesalers, retailers, and end users have got carried along on this great tidal wave of misinformation for a for quite a number of years.
Until now as the industry as a whole are starting to realise that this idea of controlling the movement of a layer of Oak by bonding it to a plywood base has limitations and in fact have the same limitations as to that of a solid floor and hence must be in effect treated the same way.
But where as the solid floor can expand and contract naturally the engineered board cannot due to it having been bonded to a plywood or cross ply sublayer which causes stress within the surface layer of the engineered board causing fracture within the oak layer.
When contraction takes place over radiant heat the surface layer may dry out excessively causing the layer of oak to shrink within itself and as it is bonded to a plywood of cross ply sub layer this contraction will be witnessed by ripping and cracking visible in the oak surface layer, these are called Fischer cracks.
When the Oak layer expands and contacts over a period of time due to seasonal change it also has a sheering effect on the adhesive that is used to bond the surface and the result is partial delimitation and in extreme circumstances were the boards have been installed over UFH full delimitation has been witnessed.
