Steel windows have long been a defining feature of architectural ambition, gracing everything from heritage properties to striking new commercial buildings. Yet, despite their reputation for elegance and durability, a number of persistent myths continue to circulate.

As a trusted leader among steel window manufacturers, Crittall Windows is committed to providing clarity, dispelling misconceptions and guiding you on the beginning of your purchase journey with confidence.

Myth 1: Steel windows are prone to rust and corrosion

A lot of people believe that steel windows are susceptible to rust and moisture damage. In reality, modern steel window services employ advanced protective coatings and galvanisation techniques that prevent corrosion.

Crittall Windows, with over a century of expertise, manufactures steel frames designed to withstand the rigours of the British climate. With proper installation and minimal regular maintenance, these windows will retain their integrity and beauty for generations.

Myth 2: Steel windows offer poor thermal insulation

The notion that metal windows allow excessive heat transfer is outdated. Today’s steel windows, such as those in the Crittall range, feature advanced glazing and thermal barriers that provide excellent insulation. This technology significantly reduces heat loss, supports energy efficiency and helps lower energy costs for both homeowners and occupants of commercial property.

Steel windows now meet stringent building codes and are a smart choice for those seeking to balance style with sustainability.

Myth 3: Steel windows require constant upkeep

The perception that steel windows demand more maintenance than aluminium windows or other building materials is misplaced. Thanks to modern manufacturing processes and durable finishes, Crittall steel windows are remarkably resilient. Occasional cleaning and routine checks are typically sufficient to maintain their functionality and aesthetic appeal.

Their longevity and minimal maintenance requirements make them ideal for busy homeowners and large commercial buildings alike.

Myth 4: Steel windows are only suitable for traditional or conservation area projects

Steel windows are often associated with period properties, yet their versatility extends far beyond heritage settings. Crittall offers a wide variety of different profiles and colours, allowing these windows to complement contemporary new builds and ambitious renovation projects as well as historic structures.

Steel glazing can be specified for casement windows, internal partitions and commercial buildings, making it one of the best solutions for diverse architectural visions.

Myth 5: Steel windows are prohibitively expensive

While the initial investment in steel windows may be higher than some alternatives, their durability, longevity and low maintenance make them a sound financial decision in the long run. The longevity of your windows means fewer replacements and repairs, and their energy efficiency contributes to ongoing savings in heating and cooling.
