As the chills of Winter start to settle across Duffield, Derby, and the wider Derbyshire area, keeping your home warm becomes a priority. One of the most effective and often overlooked ways to retain heat and reduce energy bills is by upgrading your windows. At Kedleston Glass & Glazing, we specialise in supplying and fitting high-quality, energy efficient windows designed to keep your home cosy and draught-free all winter long.
Why Energy Efficiency Matters in Windows
Windows are often the weakest link in your home’s thermal envelope. According to research from the Building Research Establishment (BRE), poorly insulated windows can account for as much as 25-30% of heat loss in a typical UK home during winter. This means that cold air seeps in and warmth escapes, making your heating system work harder and costing you more on your energy bills.
Energy efficient windows minimise this heat loss by using advanced glazing technology combined with thermally efficient frames. Their multi-layered glass panes are often filled with inert gases such as argon, which reduce convection heat transfer. Additionally, low-emissivity (Low-E) coatings reflect heat back into your home while allowing natural light in, helping you to maintain a bright yet warm interior environment.

Types of Energy Efficient Windows at Kedleston Glass & Glazing
We offer a wide range of windows tailored to suit both traditional and modern homes in Derbyshire. Whether you’re looking for the timeless charm of Heritage flush sash windows or the sleek appeal of aluminium windows, each of our products is designed with energy efficiency in mind.
Flush sash windows have a minimal gap between the sash and frame, reducing draughts and heat loss while providing excellent security. Our heritage flush sash windows are perfect for period properties, allowing you to retain the original aesthetic without compromising on performance. For homeowners preferring easier maintenance, uPVC windows offer a cost-effective, thermally efficient solution that can be customised to match any style.
Casement windows, hinged at the side, create a tight seal when closed, making them highly energy efficient. Sliding sash windows provide traditional aesthetics with modern upgrades to improve insulation. If you are looking for versatility, tilt and turn windows are an excellent option, allowing for both secure ventilation and an airtight seal during the colder months.

The Benefits of Installing Energy Efficient Windows
Upgrading your windows with energy efficient double glazing options brings tangible benefits beyond warmth. You’ll see a significant reduction in heating costs, with figures from the Energy Saving Trust suggesting that double or triple glazed windows can save you up to £175 per year on heating bills, depending on your existing setup.
These windows also reduce condensation (a common problem in cold weather) which helps prevent issues like mould and dampness. Enhanced sound insulation is another advantage, creating a peaceful indoor environment even on busy Derby streets or near main roads.
In addition, energy efficient windows improve your home’s overall value and appeal. When it comes to selling properties in Derbyshire, modern, well-performing windows are often a key selling point.
