Most of the cost and most of the life of an interior comes from what is inside the shutters. Here is a plain guide to the common choices.
Plywood
Plywood is made of thin wood layers glued together, which makes it strong and good at holding screws. It comes in grades. BWP (boiling water proof) plywood is meant for wet areas such as the kitchen sink unit and vanities. MR (moisture resistant) plywood suits dry areas such as wardrobes and TV units.
MDF and HDHMR
MDF has a very smooth surface, so it is a good base for painted or routed shutters. Plain MDF does not like water, so keep it away from sinks and bathrooms. HDHMR is a denser board that handles moisture better and is often used for shutters.
Solid wood
Solid wood such as teak is beautiful and can last for generations. It is best for doors, frames, pillars and furniture. It also moves a little with the seasons, so wide panels need to be made by someone who understands the wood.
A simple rule
- Wet areas: BWP plywood
- Dry storage: MR plywood or HDHMR
- Painted and grooved shutters: MDF or HDHMR
- Statement pieces: solid wood or veneer
Ask your interior team to write the board type and grade for each unit in the quote. It is the easiest way to compare two quotes fairly.
