Shutter material choices vary by personal choice as well as durability and structural criteria and fit for purpose use.
Building code requirements may also have an influence over these choices.
Some differences to consider:
- Aluminium conducts temperature whereas Timber is a natural insulator.
- Aluminium is more durable and better suited to external, security minded areas, high maintenance or adverse weather affected areas.
- Timber is durable as well, hardwood is more durable than softwoods for the types of chosen woods used in windows and shutters. Cedar is a very soft wood and is prone to accidental knocks and dents very easily.
- Timber is a natural product and nothing can emulate the softness and character of natural wood products.
- Polywood is a PVC based material, our Polycore system has an Aluminium core through each profile. It is very strong, does not warp and has a UV rated satin paint finish resembling our wood and Aluminium profiles. We can combine the mediums to suit the design need.
One way that insulation is created is with dead-air space.
Our panels are precision built so that they restrict the chance of draft between junctions or laps of blades. A properly constructed and installed shutter provides more insulation than a single paned glass. Other factors contribute to the insulation qualities of a shutter, such as gaskets, material type etc.
The U/R value tells how the product insulates. It is a formula derived from the efficiency of the product, and that formula takes into account many of the factors aforementioned.
A good "R" measurement is a high one, while a good "U" measurement is low.
Homeowners are more interested in the R-value, while builders are interested in the U value.
