In the realm of modern architecture and construction, the choice of materials plays a pivotal role in ensuring energy efficiency, durability, and aesthetic appeal. One of the increasingly popular options for high-performance window and door systems is the thermal break aluminium profile. This technology not only offers robust structural integrity but also enhances energy efficiency, making it an ideal choice for contemporary buildings.

A typical extrusion billet comes in form of a solid or hollow cylindrical shape.
Despite their names, both cast iron and wrought iron are actually alloys, meaning they contain certain amounts of other materials in addition to iron. Cast iron is usually 2 to 4% carbon and contains small amounts of silicon, manganese and occasionally sulfur and phosphorus. Cast iron is made either by smelting iron ore or pig iron (an intermediate iron ore product) then mixing it with carbon and other metal alloys.

While wrought iron is naturally durable, it is essential to protect it from rust and corrosion.

An excellent example of the limitations is how large a hinged window’s opening element can be. Most aluminium windows only go up to around 1.2 m or 1.5 m, with side-opening windows even smaller at 600 mm or 900 mm. So you won’t find extra-large opening windows beyond these sizes.
The bottom line here is that modern aluminium profiles are absolutely no worse insulated than wooden or, even more so, plastic ones. On the contrary, modern aluminium window profiles are distinguished by the best thermal performance and are often used in the construction of passive houses. As a result, the price of aluminium windows and doors has risen considerably in recent years, and we currently have to pay more for them than for wooden windows!
