Engineering / statics
At ThermDura we provide an engineering report for our conservatories. We work with a specialized engineer and passive house designer to achieve the most efficient and cost effective solution for your project.
CONSTRUCTION
Experts in Europe agree on one thing: The timber-Aluminium construction is the most durable and thermally most effient construction for windows, doors and conservatories today. The advantages of Aluminium and timber are combined in this construction.
Timber has got excellent load bearing and insulation characteristics. Besides this timber provides a warm atmosphere for us humans and acts as a regultor of the room climate as it is hygroscopic. As an option we also offer a timber exterior for our conservatories.
Aluminium is an almost maintenance free product and can be powdercoated in many colours. The Aluminium colour can be matched to the outside architecture of the house. The Aluminium shell ensures weather protection and low maintenance for the years to come.
