Energy Efficient Double Glazing Epsom

Energy Efficient Double Glazing Epsom

Our industry-leading uPVC windows, doors and conservatories will make your Surrey home more energy efficient. Relax in comfort, knowing that your brand-new double glazing is lowering your heating bills and reducing your carbon footprint, while also adding solid market value to your property at the same time.

Our Double Glazing Provides Superb Energy Efficiency

It’s important to choose double glazing that will add visual value to your home. Equally, your newly-fitted conservatory, doors or windows need to come armed with a range of cost-saving features that will reduce your ever-burgeoning heating costs. That’s why energy efficiency is high on the priority list of most homeowners seeking a viable double glazing solution for their property.

Poorly fitted windows, doors or conservatories create problems that will be expensive and time-consuming to fix later. From a purely cosmetic perspective, the ingress of cold drafts will cause unsightly mould-related issues to manifest themselves in your home, orangery or conservatory, which will reduce the market value of your home by making it less appealing to buyers.

It is estimated that approximately 20% of heat escaping from a home is due to badly installed double glazing. Choosing an installer with the requisite experience to complete your home improvement project is essential if you want to benefit from improved energy efficiency.

Better Energy Efficiency for Your Home, Orangery or Conservatory

If your doors and windows are performing poorly, they’ll be adversely affecting the internal climate of your home. To compensate for the heat that’s escaping, you’ll be turning up your thermostat, which will exponentially increase your heating costs. Your home will also be a less comfortable place to spend time in, which will make entertaining friends or family difficult. Investigating ways to improve the thermal efficiency of your home is, therefore, high on your list of priorities.

Double glazing that’s old or poorly fitted will return a low Windows Energy Rating (WER). These ratings were defined by the British Fenestration Ratings Council (BFRC) to provide homeowners with a way to determine the energy efficiency of their windows. The scale supplied ranges from A-G, and the highest level attainable is an -A, which indicates superior thermal performance.

Regarding attaining a minimal level of energy efficiency, windows need to achieve a ‘C’ WER rating as a minimum. By using this scale as a metric, homeowners have access to a viable benchmark to identify whether any further steps are needed to make their home more thermally efficient. Our range of high-performing window profiles will meet your requirements in full.

Energy Efficient

Energy Efficient, Sustainable and Eco-Friendly

The technology incorporated into the frames of all modern windows, doors and conservatories is designed to conform to the minimum standards laid down by the BFRC. Thermally broken profiles, which trap convection currents and create a thermal barrier designed to lock in heat and block out cold air, work to create interior environments that provide superior energy efficiency – regardless of the weather.

A range of glazing options is available to homeowners. Low emissivity glass is invisibly coated in a metal oxide that adheres to one of the internal planes. It permits the entry of light and heat but prevents the warm air from escaping. This dramatically improves the energy efficiency of the designated space.

The gap between the panes of glass in a window is sometimes filled with gas – ordinarily Argon or Xenon – which improves the energy efficiency of the profile in question. Gas-filled windows like these will supply superior U-values, which could be 30% higher than that of a standard double glazed window.
