Velux Windows Upgrades: When and Why to Replace Your Glass

Double Glazing vs. Triple Glazing

Double Glazing: This option features two panes of glass separated by a layer of insulating gas, usually argon. Double glazing offers excellent thermal performance, reducing heat loss in winter and minimising heat gain in summer. It’s an ideal choice for standard Velux window upgrades, providing a balance of insulation and cost-effectiveness.

Triple Glazing: For those looking to take insulation to the next level, triple glazing adds a third pane of glass, creating two insulating layers of gas. This setup significantly improves thermal performance, noise reduction, and energy efficiency. If you’re upgrading Velux windows in a loft conversion or a bedroom, triple glazing can enhance comfort by reducing noise from outside and keeping the temperature stable year-round.

Understanding U-Values

What is a U-Value? The U-value measures how well a window can prevent heat from escaping. The lower the U-value, the better the insulation. Upgrading to our high-performance Velux glazing can significantly reduce heat loss, keeping your home warmer in winter and cooler in summer.

Comparing U-Values: Traditional single-pane windows have a high U-value (around 5.0 W/m²K), meaning they lose heat quickly. Our double glazing has a U-value as low as 1.1 W/m²K, while our triple glazing goes even lower, offering U-values of around 0.7 W/m²K. This means greater insulation, less heat loss, and lower energy bills.

Why Our Glazing is Perfect for Velux Windows

Optimal Insulation: Our Velux glazing options are specifically designed to offer superior thermal performance. Whether you choose double or triple glazing, you’ll benefit from enhanced insulation, reducing the need for additional heating during colder months.

Solar Control: Our glazing solutions are engineered to balance natural light with solar control. The combination of Low-E coating and UV protection ensures that your rooms stay bright and airy without becoming overly hot, even in the summer months.

Noise Reduction: The high-quality construction of our Velux glazing also provides excellent sound insulation. This is especially beneficial if your windows face busy roads or noisy neighbourhoods, turning your loft or attic into a quiet, comfortable space.

Durability and Longevity: With toughened glass options and protective coatings, our Velux glazing is built to withstand the elements, offering long-lasting performance with minimal maintenance.
