What Makes Our Windows Better?
Our most energy efficient triple glazed windows introduce a slimmer frame whilst maintaining dual compression seals for achieving high air tightness standards. Make a genuine difference to the comfort of your home by keeping your home warm during the colder months and cooler during the summer.
So, trust in our 30 years of experience helping people create energy efficient dream homes. Let us be part of your team, and we’ll be with you every step of the way, delivering comfort by making buildings better.
Due to the complexity of specifying our products, we have a minimum order policy. To realise the benefits of triple glazing, including the continuity of thermal performance, we only recommend replacing windows throughout all of your home for replacement or retrofit projects.
What Are Triple Glazed Windows?
Windows that are triple glazed have three panes of glass instead of the more common single or double glazed windows. The extra argon filled cavity in a triple glazed window offers an extra layer of insulation, making them more energy efficient.
How Do Triple Glazed Windows Work?
Each layer of glass is separated by sealed gaps of Argon. These gaps act as insulation that keeps your home warm in the winter and cool in the summer.
Our triple glazed windows have the following features:
- Low u values: Argon triple glazing as standard for comfort and great thermal performance
- Airtightness: Dual air compression seals ensure long term airtightness to class 4
- High security: Multipoint locking tested to Secured by Design standards
