Anyone familiar with the Eucalyptus tree knows that its wood is far superior to most other trees. The grain is smooth and the colour is matchless. Van Acht’s Calyptus window range is made exclusively from the wood of these majestic trees. Great pains have been taken to ensure that the manufacturing process is as sustainable as possible. This means that forests are well managed, sources are controlled, and materials are reclaimed wherever possible.

In addition to the superior wood that these windows are made from, we also ensure that high quality fittings accompany them. Satin chrome handles look and work great. Full 90-degree hinges ensure a longer lifespan and functional practicality. All of these benefits come at an unbelievably reasonable price. So if you’re on a budget, we highly recommend our Calyptus window range.

FSC Logo

Merensky Eucalyptus products are FSCTM certified. FSCTM certification is intended to provide a credible guarantee to customers, whether business, government or end consumer, that products sold with a specified FSCTM certificate originate from well-managed forests, controlled sources, reclaimed materials, or a mixture of these.

The windows are less bulky and much better priced than our standard windows, yet we use the same satin chrome handles and full 90-degree hinges on the Calyptus range that we use on our top of the range Manor Windows .

Up to 40% cheaper than equivalent Aluminium window!
