U-Values Explained
A simple way to compare thermal performance
U-values measure how effectively a window or door prevents heat from escaping.
The lower the U-value, the better the thermal performance.
Our windows and doors are engineered with multi-chamber frames, high-performance seals and advanced glazing to achieve excellent U-values across the range.
Double Glazing
Double glazing consists of two panes of glass separated by an insulating cavity.
Improved Thermal Insulation
The insulating cavity between the glass panes helps reduce heat loss, keeping your home warmer in winter and cooler in summer. This can improve everyday comfort and support lower energy use.
Reduced Condensation
By maintaining a warmer internal glass surface, double glazing helps minimise condensation forming on the inside of your windows. This supports a healthier indoor environment and helps protect surrounding frames and finishes.
Enhanced Acoustic Comfort
Two panes of glass create an effective barrier against external noise. This can noticeably reduce everyday sounds from traffic or neighbouring activity, helping your home feel calmer and more peaceful.
Excellent Balance of Performance and Value
Double glazing offers strong all-round performance without unnecessary complexity. It’s a reliable, proven solution that delivers comfort, efficiency and durability at a sensible price point.
Availability
Available across all window and door styles. Flush casement windows are available with double glazing only

Triple Glazing
Triple glazing uses three panes of glass and two insulating cavities for enhanced performance.
Exceptional Thermal Insulation
With three panes of glass and two insulating cavities, triple glazing significantly reduces heat loss. This makes it an excellent choice for homeowners prioritising energy efficiency and year-round comfort.
Improved Internal Comfort in Colder Months
The additional glass layer helps maintain a more consistent internal temperature, reducing cold spots near windows. Rooms feel warmer and more comfortable, even during winter.
Further Reduction in External Noise
The extra pane of glass provides increased sound insulation, helping to soften traffic noise and other external disturbances. This can make a noticeable difference in busier or more exposed locations.
Greater Temperature Stability and Reduced Drafts
Triple glazing helps minimise heat transfer and cold air movement around the window area. This supports a calmer, more stable indoor environment and enhances overall living comfort.
Availability
Available on selected window styles. Not available on flush casement windows
