What MDF shutters are
Medium density fibreboard is wood fibre bonded with resin and pressed into board. It is dimensionally stable, it machines cleanly and it takes a sprayed finish well, which is why it is used in a great deal of fitted furniture.
Its problems as a shutter material are density and water. MDF is considerably heavier than the hardwoods used for shutter panels, and a shutter is a hinged object carrying its own weight all day. It also swells irreversibly if it gets wet, which rules it out for bathrooms and makes it a poor bet at a kitchen window above a sink.
How the materials compare
| Material | Character | Best for |
|---|---|---|
| Paulownia | Light, stable hardwood. The workhorse of our painted range. | Most rooms in most houses. The default for a painted finish. |
| Basswood | Fine, even grain that takes paint or stain beautifully. | Where the finish quality is the priority, and for stained panels. |
| Ashwood | Open grain with real character, best shown off in a stain. | Rooms where you want visible timber rather than paint. |
| Hybra | Engineered core with a hardwood face. | Strength over wide spans, and tall panels that must stay flat. |
| Waterproof PVC | Fully water resistant throughout. | Bathrooms, wet rooms, utility rooms and real humidity. |
| Fauxwood | Hard wearing and cost effective, with a painted timber look. | Budget conscious projects and secondary rooms. |
| MDF | Heavy, water sensitive, cheap. | Not something we supply. |
Why weight matters more than people expect
A shutter panel hangs from two or three hinges and is opened and closed for years. Every extra kilogram is load on those hinges and on the frame fixings, and it is the main reason budget panels start to drop at the leading edge and catch on the frame.
Weight also limits how wide a single panel can be before it needs splitting, and more panels means more stiles across the glass and less view out. A lighter material buys you a cleaner window.
Where each of ours goes
In practice most of what we fit is Paulownia in a painted finish, because it does the job in a living room, a bedroom or a hallway and it does not add cost that you would not notice.
Basswood goes in where the finish is the whole point, particularly on stained panels where the grain is visible. Ashwood goes in when someone specifically wants the timber to read as timber.
Hybra earns its place on tall or wide openings where a panel has to stay flat over a long span. Waterproof PVC goes in every bathroom without discussion, and we will not fit a timber panel over a bath or in a shower room whatever the customer asks for.
