Crittal Windows & Doors Current Trends And Product Deep Dive

Crittall – A Product Deep-Dive

These days, you can’t turn on a high-end architectural design show without seeing floor-to-ceiling interior steel screens or crittall style windows and stunning crittall style bifold doors. Offering minimal sightlines and super slim profiles, the crittall style has never been more popular for consumer, commercial, and heritage applications alike.

So, what is crittall? The crittall look is one that has been absolutely dominating the interior design world over the past few years, and for good reason, it looks genuinely stunning.

Essentially the crittall style means thin black steel or aluminium frames with glass panels and our range windows and doors have been specially designed and developed to meet the exacting requirements of refurbishment and renewal projects as well as, the most modern look of new-build projects as our current trends section further down will highlight.

Aluminium Advantages

Our Crittal style range is fabricated in aluminium which means they offer a high strength, light weight and cost effective solution to heritage renovation projects and modern homes alike, where thermal efficiency is of the utmost importance.

Check out the following benefits:

  • Increased lifespan – Aluminium is widely regarded as having the longest lifespan of any framing material and the typical replacement period is a whopping 40 years.
  • Low maintenance – Aluminium frames will never require repainting as they will never fade, all that is required for maintenance is a routine wipe down to keep the frames looking their best.
  • Increased thermal efficiency – Most modern aluminium frames are thermally broken using polyamide as an insulator which reduces thermal transmittance offering outstanding thermal performance.
