Replacements for Steel Windows
With sightlines less than 33mm deep our slimline aluminium windows are the perfect replacement for steel windows (including Crittall© Windows).* Our innovative/Trademarked aluminium profile has been specially designed to give a similar aesthetic to steel windows but with all the advantages in security and efficiency of a modern aluminium window.
With a full thermal break (separating the cold outside of your windows from the warm inside of your home) our profiles can easily be installed into existing or new timer sub frames or directly into stone or brick, making installation fast and cost-effective.
Many Heritage windows customers are choosing to replace old steel windows with new aluminium windows, due to the benefits of aluminium. Our aluminium windows give a very similar look to steel windows, but with many additional benefits including:
- Slim thermally broken aluminium profiles with a sightline of just 32.5mm
- Installable into existing or new timber sub frames or direct to brick or stonework
- Highly secure with modern multi point locking to PAS24
- Low maintenance
- Long-lasting and rust-free
- Competitively priced
- Fantastic sightlines
- 10 year warranty
