Environmentally Friendly Using Non-toxic Recycled Materials

Thermalite Plantation Shutters is the look and feel of wood with several major advantages. Thermalite is the GREEN CHOICE. It’s the only 100% synthetic material that looks and feels exactly like timber. Thermalite is a solid non toxic polymer foam and is a ‘by-product’ of natural gas – no natural resources (including trees) are destroyed in the manufacturing of this product and unlike vinyl/PVC it contains no toxic ingredients. It is also more friendly to the environment, using less resources in production, and does not break down into toxic chemicals when they are disposed of.

Thermalite is also tested and proven via independent testing carried out by the National Association of Home Builders Centre (U.S). In that testing it showed that the R factor for Thermalite is nearly three times that of timber. This means that, compared to timber, it takes nearly three times the amount of energy applied to one side of a piece of Thermalite to raise the temperature on the other side one degree centigrade. To be specific, the R factor for PVC is R2.18, while the R factor for Thermalite is R6.1 (U.S imperial statistics).


Quality Product that’s Made to Last

Every single Thermalite Plantation Shutter comes with a structural 25-year transferable warranty in addition to the paint finish that will be warranted for 5 years against yellowing, cracking or peeling. Every one of these shutters are custom-made in order to fit any kind of door or window and precisely fitted by us. Moreover, you can choose from a variety of styles, including hinged, fixed, bi-fold as well as sliding.






Installation Types

Thermalite Plantation Shutters is custom made in a range of flexible installation methods including, fixed panels, bi-folds, traditional shutter hinged, and sliding.


The most common and cost effective installation method is Traditional Hinged in Z-frame. By using this method it hides the gaps on openings that are out-of-square and/or out-of-shape. In addition, it also brings the panels closer into the room meaning you don't need as deep a reveal to fit Thermalite Plantation Shutters.  The reveal depth required on a 90mm blade using Z-frame is 55mm, and 70mm using L-frame.

UltraClear Mechanism & Elliptical Louvres

The louvres (blades) rotate using the patented Ultraclear Mechanism that’s hidden inside the stile and that means no more unsightly connector rods that most manufacturers use as standard. Basically, this is a unique system that uses a hidden gearing system that allow the blades to rotate together. This is very important, as the weakest and most likely part to fail on a plantation shutter is the screw used to connect the connector rod! In addition, the shutters also feature elliptical louvres that have a hidden reinforced aluminium core.

Easy to Clean

Thermalite Shutters are incredibly low-maintenance. A gentle dusting with a feather duster is usually sufficient, given that each meter contains around twelve 90mm blades, allowing most panels to be cleaned in under a minute. In case of more stubborn dirt and grime, a solution of warm, soapy water with mild dishwashing detergent can be applied using a microfiber cloth, ensuring that your shutters retain their stunning appearance for many years.
