The insulation properties of Open Shutters
Window shutters from Open Shutters have great insulation properties. This can be put down to the fact that the right materials are used in their construction and care is taken with their fit.
In fact, Western Red Cedar which is used in the manufacture of these shutters has the best insulation qualities of any wood. Tests show that they reduce heat transfer by 47% and that 1cm of Western Red Cedar is equal in insulation terms to 4cm of brick.
In addition, the tighter the air gap between the shutter and window, the better the insulation effect. This is another benefit of Open's made-to-measure handcrafted shutters and individually made joinery.
