Double glazing will provide noise insulation, enhanced security and thermal efficiency to your Wiltshire or Oxfordshire home…
Double glazed windows are the minimum window requirement...

The vast majority of UK homes are double glazed, but there still remain a surprising number of properties with single glazed windows. You’d be unwise to not make the leap to modern double glazing as the thermal efficiency levels of a double-glazed window are far in excess of those offered by a single glazed window.

Future-proof your home from energy price hikes with our energy-efficient glazing. The insulating cavity between the two glazed panes ensures this is the case. For the biggest reduction in fuel costs, include A+ rated glass in the window.

If you live on or near a busy road, it can also be part of the solution to create a quieter, more peaceful home.

Our fade-resistant aluminium windows equate to making a vibrant impression...

Once you have decided on a colour, your aluminium window will go through an 11-stage powder coating process to induce strong paint adhesions. This will ensure the colour is of the highest quality with a beautiful sheer finish. If you choose one of our aluminium woodgrain finishes, such as Walnut, Oak or Rosewood, your window will go through a sublimation process to give it the look of timber.

Double glazed windows really are essential for any home in the UK, but some homes do still have single paned windows. If you’re considering upgrading your windows, our team is on hand to answer any questions you have, in the meantime we’ve answered some of the most commonly asked questions about them below. Why not visit our showroom to see our fantastic range of windows for yourself?

How much energy can modern double glazing save compared to existing windows?

Double glazing is known to significantly improve energy efficiency compared to existing windows.

The specific amount of energy saved can vary depending on various factors such as the condition of the existing windows, the type of double glazing installed, and the property itself.

Generally, double glazing’s enhanced insulation properties create a more thermally efficient environment, potentially resulting in notable energy savings by reducing heat loss and improving temperature regulation.
For a more precise estimation tailored to your situation, we recommend consulting with our experts who can provide personalised insights and guidance based on your Oxfordshire or Wiltshire home.

How does double glazing keep a home energy efficient and how much does it cost?

At TWC, we understand the importance of energy efficiency in homes across Wiltshire and Oxfordshire.

Double glazing plays a pivotal role in enhancing energy efficiency by providing superior insulation. The dual glass panes separated by a layer of gas create a thermal barrier, effectively minimising heat transfer and maintaining more stable indoor temperatures. This reduces the reliance on heating systems, potentially lowering energy consumption and utility costs.

Regarding the cost of double glazing, prices vary based on numerous factors such as window size, materials, and installation requirements. At TWC, we offer bespoke solutions tailored to individual needs.

For an accurate quote and to explore the options best suited to your home, we encourage you to contact our knowledgeable team. We are committed to providing competitive pricing and high-quality double glazing solutions designed to enhance energy efficiency, while adding value to your Wiltshire and Oxfordshire property.

What materials are available for double glazing frames? Will will it help reduce outside noise?

Various materials are available for double glazing frames, each offering distinct advantages.

TWC offers a diverse range including the Extreme UPVC range, Eclipse aluminium, and Envisage flush windows crafted from UPVC. The Extreme UPVC range boasts durability and excellent insulation, while Eclipse aluminium frames offer strength and a sleek modern aesthetic. Envisage flush windows combine the classic look of flush casement windows with the benefits of UPVC, blending timeless style with efficiency.

Double glazing significantly aids in reducing outside noise infiltration. The insulation provided by the two glass panes separated by a layer of gas acts as a barrier, minimising the transmission of external sound into your Wiltshire or Oxfordshire home.

Choosing high-quality double glazing frames, such as those offered by TWC, enhances noise reduction, providing a quieter and more peaceful indoor environment. For specific noise reduction capabilities and advice tailored to your needs, we recommend consulting our experts for personalised guidance.

Does it reduce condensation on windows?

Double glazing significantly minimises condensation on windows.

The insulating design of double glazing, consisting of two glass panes separated by a layer of inert gas, helps maintain more consistent indoor temperatures. This thermal barrier reduces the likelihood of the inner pane becoming cold, which in turn prevents condensation from forming.

By preventing drastic temperature differences between indoor and outdoor environments, double glazing effectively combats condensation, ensuring clearer and drier windows.

Its insulating properties not only enhance comfort but also contribute to maintaining a healthier and more pleasant indoor environment by mitigating condensation issues.
