Mdf is medium density fibreboard.
Chipboards are made of wood chips packed up together with resin so to stay together.
Some chipboards are better than others, denser and heavier.
When you cut it you feel the difference compared to cheaper, lighter chipboards.
Howdens use a 18mm chipboard, melanine faced for their carcasses and they're ready built.
You won't believe how much time that saves.
Also, howdens carcasses have a solid 12mm or 15mm back chipboard, while the diy from b&q or
wickes have a 3.5mm mdf panel which pops off as soon as a pan is pushed against it.
When I had to fit such kitchens I would ask the customer to
1. Send me an email confirming that they understood the fragility of these back boards and accepted full responsibility for it
Or
2. Pay me to re-inforce them so they won't pop off.
