The Complete Guide to U-Values and Choosing Energy Efficient Windows

At Bluemanor Windows, we understand the importance of energy efficiency for your home. And with increasing concerns over the environment and global warming, investing in energy efficient windows has never been more important. Not only are energy efficient windows good for the environment however, they will also contribute significantly to saving on household energy costs. 

Whether you're replacing old windows or installing new ones in a recent build, energy efficiency should be a key concern. This guide by Bluemanor will walk you through everything you need to consider when choosing energy efficient windows.

Understanding U Values: What are They? 

A crucial aspect in selecting energy efficient windows is understanding the U-values of the windows. This term essentially refers to the rate of heat transfer through a window. The lower the U value, the better the insulation properties of the window, meaning less heat is lost during winter and less heat enters during summer. At Bluemanor Windows, we offer windows with low U values to ensure maximum thermal efficiency.

Types of Energy Efficient Windows

Double Glazing

Double glazed windows consist of two layers of glass with a gap in between, usually filled with air or argon gas. This design minimises heat loss, helps reduce noise, and decreases condensation inside the window.

Triple Glazing

For even greater energy efficiency, consider triple glazed windows which include a third layer of glass and additional airspace. These are particularly beneficial for extremely cold climates, providing superior insulation by further reducing heat transfer and enhancing soundproofing qualities.

Low-Emissivity (Low-E) Glass

Low-E glass has a microscopically thin coating of metal oxide on one of the glass surfaces inside the window. This coating reflects heat back into the home while still allowing in the natural light from the outside. Windows equipped with Low-E glass can significantly lower energy costs by improving thermal efficiency.

Window Frame Materials

The material of the frame also plays a significant role in the efficiency of a window. Each material offers different aesthetic and thermal properties:

• uPVC - Unplasticised Polyvinyl Chloride, or uPVC, is a popular choice due to its excellent insulation capabilities, low maintenance, and durability. It does not conduct heat, making it more energy efficient than metal frames.

• Wood - Wooden frames are not only stylish but also provide natural insulation properties. They require more maintenance than uPVC but can offer a traditional look that many homeowners desire.

• Aluminium - Aluminium frames are strong, durable, and slim, providing more glass area. When equipped with a thermal break, they become more energy efficient.

Installation and Proper Sealing

No matter how energy efficient a window is in terms of materials and design, poor installation can negate all benefits. Proper installation is crucial to ensure that there are no gaps or leaks around the frame, which would allow air infiltration and reduce the overall efficiency of the window.
