There is quite little to be found on the internet about the door manufacturers (probably all of them are solid)
On site we will probably look at the doors live next week and get some advice there again
I can only find out the prices on site as we are bound to this supplier
Our current favorite is Dextüra because of their Superlak
I would still like to hear experiences about the Dextüra doors from everyday use and possibly longer use (if any of you have them)
