Windows
Energy rated windows
Installing energy efficient windows can vastly improve the energy efficiency of your home, saving you money and providing you all year round comfort.
Regulated by the British Fenestration Ratings Council ( BFRC) you can be assured that what it states on our energy label is what you are going to get.
To conform to current regulations, replacement windows must meet the minimum standard of a “C” rating or an overall “U” value of 1.6 W/m².K .
Our UPVc windows are designed to the highest standards which means that our minimum energy rating is a “A”. The sealed unit used in this window is 28mm wide, argon filled, with an aluminium spacer bar and a low ‘E’ soft coating to the internal pane. This provides a very cost effective method of achieving a high energy rating.
For the ultimate in energy efficiency without a large cost implication choose our “A” rated window. This has the addition of a thermal spacer bar, providing one of the most efficient windows in the market today.
Triple Glazing
Upgrade Your Comfort: Triple Glazing vs. Double Glazing
If you’re looking to improve your home’s energy efficiency, the windows are the best place to start. While double glazing has been the standard for decades, triple glazing is rapidly becoming the go-to choice for homeowners who want maximum comfort and long-term savings.
But is that extra pane of glass really worth it? Let’s break down the science.
What’s the Difference?
The fundamental difference lies in the construction. While double glazing uses two panes of glass with a gas-filled space between them, triple glazing adds a third pane and a second insulating cavity.
The Physics of Insulation
Both systems use an inert gas (usually Argon or Krypton) between the panes. This gas is denser than air, which slows down the transfer of heat. By adding a second cavity, triple glazing creates an even more formidable barrier against the elements.
Why Triple Glazing Wins: Key Comparisons
| Feature | Double Glazing | Triple Glazing |
| U-Value (Heat Loss) | Typically 1.2 to 1.6 | As low as 0.8 or less |
| Surface Temperature | Can feel cool to the touch | Stays close to room temperature |
| Sound Reduction | Good (standard) | Superior (reduces decibels significantly) |
| Security | Standard protection | Enhanced (harder to breach) |
1. Superior Thermal Efficiency
The “U-Value” measures how effective a window is at preventing heat from escaping.
2. Eliminating the “Cold Spot”
Have you ever sat near a window in winter and felt a draft, even if the window was shut? That’s often convection. When warm room air hits cold glass, it cools and sinks, creating a cycle of cold air. Because the internal pane of a triple-glazed window stays much warmer, this “draft” effect is virtually eliminated.
3. Noise Reduction
If you live near a busy road or under a flight path, triple glazing is a game-changer. The extra pane and varying thicknesses of glass disrupt sound waves more effectively, creating a significantly quieter indoor environment.
Is it Right for You?
While the initial investment for triple glazing is higher, the benefits in energy savings, acoustic comfort, and property value often outweigh the cost over time—especially in colder climates or noisy urban areas.
Pro Tip: If you’re only replacing windows in a south-facing room that gets lots of sun, modern double glazing might suffice. However, for north-facing rooms or bedrooms near a street, triple glazing is the gold standard.
