With energy prices continuing to climb, homeowners across Bristol and Bath are searching for practical ways to cut their household costs. Double glazed windows remain one of the most effective home improvements for reducing energy bills while making your living space more comfortable throughout the year.
At DM Windows, we’ve helped countless local homeowners transform their properties with high-quality double glazing installations. The right windows can make a significant difference to both comfort and running costs.
Let’s take a closer look at exactly how high quality glazing works to save you money, and why it might be the smart choice for your home.
The Science Behind Double Glazing and Energy Efficiency
Double glazing works by creating an insulating barrier that standard single pane windows simply cannot provide. Rather than having just one pane of glass separating your home from the outside world, double glazing features two glass panes with a carefully sealed gap between them.
This gap is usually filled with argon gas – an inert gas that conducts heat much less efficiently than air. The sealed unit also includes a spacer bar around the perimeter, which keeps the glass panels perfectly positioned while helping to prevent heat transfer around the edges.
How Double Glazing Reduces Heat Loss
The average home loses approximately 20% of its heat through windows. Single pane windows are particularly problematic because glass is a good conductor of heat, meaning warm air inside your home quickly transfers to the cold air outside.
Double glazing addresses this problem in several ways:
- Trapped gas barrier: The layer of argon gas between glass panes is key to the window’s insulation properties, dramatically reducing heat transfer
- Quality seals: Modern double glazing units are precision-sealed to prevent warm air escaping
- Improved frames: Our uPVC and aluminium window frames provide additional thermal insulation around the glazed unit
- Warm edge spacer bars: These components reduce heat loss around the perimeter of the glass
The result is a window system that keeps your expensive heated air inside where it belongs. When less heat escapes, your central heating doesn’t need to work as hard to maintain room temperature, leading directly to lower heating bills.
Additional Benefits Beyond Energy Savings
While lower energy bills are often the primary motivation for installing double glazing windows, there are several other significant advantages worth considering.
Noise Reduction
The same technology that prevents heat transfer also blocks external noise. The two glass panes with the gas-filled gap between them create an excellent barrier against noise pollution. This is particularly valuable for homes near busy roads, flight paths, or in bustling urban areas of Bristol and Bath.
Reduced Condensation
Condensation forms when warm, moist air hits a cold surface. Double glazing keeps the inner pane of glass warmer, significantly reducing the likelihood of condensation forming. This means less wiping of windows and a lower risk of mould growth around window frames.
Added Security
Double glazed units are inherently more difficult to break through than single pane windows. At DM Windows, we enhance this security further with multi-point locking systems on all our window styles, giving you peace of mind alongside energy efficiency.
Added Property Value
Quality replacement windows not only save you money while you live in your home but can also increase your property value when it’s time to sell. Potential buyers recognise the value of energy-efficient windows, and homes with modern double glazing typically command higher prices.
Is Triple Glazing Worth Considering?
For those seeking the best possible thermal performance, DM Windows also offers triple glazing options. As the name suggests, triple glazing adds a third pane of glass and a second insulating gas layer.
Triple glazing provides:
- Around 40% better insulation than standard double glazing
- Further reduced heat loss and even lower energy bills
- Superior noise reduction properties
- Almost complete elimination of cold spots near windows
Our triple glazed windows can achieve impressive A++ window energy ratings, representing the very best in energy efficiency. While they represent a higher initial investment, for those planning to stay in their homes long-term or those in particularly cold or noisy locations, triple glazing offers exceptional performance.
Window Styles and Options at DM Windows
At DM Windows, we understand that energy efficiency needs to come with a style that matches your home. That’s why we offer double and triple glazing across our entire range of window styles:

Frequently Asked Questions
How much could I save by switching from single to double glazing?
The exact savings depend on your current windows, home size, and heating habits. However, most households see a reduction of 10-25% on their heating bills after installing quality double glazing. With today’s energy prices, this typically means annual savings of £100-200 for an average home.
How long does double glazing last?
Quality double glazing from DM Windows is built to last. Our uPVC windows typically perform well for 20-25 years, while our aluminium windows can last 30+ years with minimal maintenance.
Can I install double glazing if I live in a conservation area?
Many homes in Bristol and Bath’s conservation areas face restrictions on replacement windows. At DM Windows, we offer several solutions, including our Residence Collection windows, which replicate traditional designs while providing modern thermal efficiency.
