Environmental commitment underpins all our activities at Thermotek, with our company taking a holistic approach to all policies and procedures. 

Our sustainability focus is three-fold. From our own offices to the materials that go into our products, and the environment in which they are manufactured, we aim to minimise environmental impact through continuous improvement. 

Some of the practices we adopt include: source reduction, use of recyclable and recycled materials, degradability and encouraging re-use where possible, without compromising on quality. 

Our Victorian head office has also implemented several green initiatives, including:

•    Efficient glazing of all office windows
•    Environmental lighting - lights automatically switch off after a period of non-movement, minimising electricity usage
•    Water tank usage
•    Wall insulation

Importantly, our energy efficient doors and windows stand to benefit your home or property the most. We offer a range of solutions to keep you warmer in winter and cooler in summer, reducing both energy bills and your carbon footprint, and increasing the resale value of your property.
