In today's environmentally conscious world, energy efficiency is more important than ever. Quality window and door fittings can greatly contribute to better energy performance in a home. For example, weatherstripping and insulated window frames help minimize air leaks, keeping interiors comfortable regardless of external temperatures. This can lead to significant savings on heating and cooling costs, as homeowners rely less on HVAC systems. By investing in high-quality fittings that prioritize insulation and energy efficiency, homeowners can reduce their carbon footprint while enjoying a more comfortable living environment.

Aluminium profiles are also characterised by the greatest stability among the materials used for windows. They are lightweight and durable, making them the best choice for the installation of large and heavy glazing. A typical frame can hold burglar-proof glass packages weighing as much as 50-60 kg/m2! In addition, aluminium is easily mouldable, allowing the creation of a variety of window shapes, such as rectangular, round or arched. Thanks to its high stability and strength, the profile can be relatively narrow, allowing for large glazings with almost no visible frame.

With proper care, it can last for generations, making it a sustainable investment for homeowners and businesses alike.

Cast iron fencing is typically chosen for its ornate and precise designs, made possible by the casting process which allows intricate patterns and shapes. This type of fencing is quite strong and can withstand significant wear. However, cast iron is technically more brittle than wrought iron: meaning it’s more likely to crack or break rather than bend if subjected to high impact or pressure.

What’s more, aluminium blends in perfectly with simple yet modern shapes, making it a fashionable element in the construction industry.
