How Brackenwood Turns Old Windows Into Energy Savings for Homeowners

Unlike most installers, Brackenwood uses a closed loop recycling system to benefit both the environment and your budget. The video shows how old uPVC frames, glass units, aluminium profiles and hardware are processed, sorted and recycled to achieve an outstanding 98% recovery rate. The revenue created from this recycling programme is then used to reduce the cost of our advanced triple glazed window systems, giving homeowners an instant financial advantage when choosing A plus plus thermal performance. This circular approach cuts waste, lowers carbon impact and enables more families to enjoy warmer homes, reduced energy bills and a long term sustainable upgrade at a far more affordable price.

A Circular Recycling Process That Offsets the Cost of Your New Triple Glazed Windows, 98% Material Recovery, Lower Energy Bills and a More Sustainable Upgrade

Brackenwood recycles up to 98% of every old window, door and conservatory and uses the income to reduce the cost of our premium A++ triple glazed windows for homeowners.

Triple glazing offers enhanced security features that provide homeowners with peace of mind. With an additional layer of glass, triple glazing significantly increases resistance to break-ins compared to double glazing, as there is yet another layer to get through.

The added security of triple glazing is particularly beneficial for those living in areas with higher crime rates or vulnerable to burglary attempts.

Greater Acoustic Values with Triple Glazing

In addition to providing unrivalled insulation, the multiple layers of triple-glazed glass and gas act as an effective sound barrier, keeping unwanted external noises at bay.

This is particularly advantageous for residences located in busy urban areas or near high-traffic zones, where unwanted noise can be a constant challenge.

Whether you live near a busy road, construction site, or in a noisy urban area, triple glazing can significantly reduce the impact of external noise, allowing you to enjoy a quieter home.

For many homeowners in Hampshire, Berkshire, Surrey, Dorset & West Sussex, uPVC windows are a popular choice thanks to their affordability and reliable performance. This weather-resistant material is designed to withstand the elements with minimal upkeep – a quick wipe down with soapy water is all it takes to keep it looking its best.

uPVC is highly versatile, complementing both modern and traditional properties. While it may not have the same long-term durability as aluminium, it offers an excellent balance of value and functionality. For a cost-effective, low-maintenance solution that enhances your home’s energy efficiency and security, uPVC remains a smart option.

Combining strength, style, and sustainability, aluminium windows are an excellent choice for homeowners in Hampshire, Berkshire, Surrey, Dorset & West Sussex seeking an upgrade. Their slim yet strong frames allow for larger panes of glass, maximising natural light and creating uninterrupted views of your surroundings.

Aluminium is durable and resistant to warping, meaning these windows deliver exceptional performance with minimal maintenance. As a fully recyclable material, it is a sustainable material. With customisation options – from colours and finishes to hardware styles – aluminium frames offer a sleek, contemporary aesthetic alongside outstanding security and energy efficiency.

Timber windows were originally the traditional choice for homes across Hampshire, Berkshire, Surrey, Dorset & West Sussex. Wood is a natural insulator, offering excellent thermal performance thanks to its low heat conductivity. It’s also a renewable material – ideal for homeowners seeking a sustainable option.

In conservation areas or listed properties around Hampshire, Berkshire, Surrey, Dorset & West Sussex, timber windows are often a requirement to maintain heritage aesthetics. That said, modern uPVC and aluminium alternatives can now replicate the classic timber appearance with advanced finishes and detailing, providing a traditional look with modern benefits like reduced maintenance and improved durability.

What are triple glazed windows?

Triple glazed windows use three panes of glass separated by insulating cavities that are filled with argon gas. This design reduces heat loss, improves comfort and helps your home stay warmer for longer with less reliance on heating.

How do triple glazed windows improve energy efficiency?

Triple glazing improves energy efficiency by slowing the transfer of heat through the glass. The additional pane, the gas filled chambers and the Low E thermal coatings reduce heat loss and allow modern triple glazed units to achieve A plus plus energy ratings and very low U values.

Are triple glazed windows more secure?

Yes, triple glazed windows include an extra pane of glass which increases strength and resistance. Combined with Secured by Design approved locks and reinforced frames they offer a higher level of home security.

Do triple glazed windows reduce noise?

Triple glazing can significantly reduce outside noise because the extra pane and the insulated cavities disrupt sound waves. This is particularly effective for homes near main roads, schools or flight paths.

Are triple glazed windows worth the investment?

Triple glazing can be an excellent long term investment due to improved insulation, lower heating bills and enhanced home comfort. Many customers find that the benefits outweigh the initial cost, especially in colder climates or homes seeking the highest performance.

How do I get a quote for triple glazed windows?

You can request a quotation at any time using Brackenwood’s remote quote system or by arranging a home visit. A consultant will take accurate measurements and provide a tailored price based on your chosen style and specification.

How much do triple glazed windows cost

The cost of triple glazed windows varies depending on size, style and specification. While usually more expensive than double glazing, A plus plus rated triple glazing can reduce heating bills and improve long term comfort. A personalised quotation provides the most accurate price.

What U value can triple glazed windows achieve

High quality triple glazed windows can achieve U values as low as zero point eight or better when paired with energy efficient frames and warm edge spacers. Lower U values mean better insulation and reduced heat loss.

Are triple glazed windows better than double glazing

Triple glazing provides superior insulation, better noise reduction and increased comfort, although double glazing remains an excellent option for many homes. The best choice depends on your property, heating usage and desired performance levels.

Do triple glazed windows stop condensation

Triple glazing can reduce internal condensation because the inner pane stays warmer, which lowers the risk of moisture forming. Good ventilation throughout the home remains important for managing humidity.

Are uPVC or aluminium triple glazed windows better

Both uPVC and aluminium frames can deliver excellent results. uPVC offers strong insulation and value, while aluminium provides slimmer sightlines and a modern appearance. The best choice depends on the style of your home and your preferred look.

Do I need planning permission for triple glazed windows

Most homes do not require planning permission for triple glazing because it is considered a like for like replacement. Listed buildings or properties in conservation areas may require approval, and Brackenwood will advise before installation.

How long do triple glazed windows last

High quality triple glazed windows can last twenty to thirty years or more when installed to BSI and FENSA standards. Brackenwood provides a full guarantee and uses products designed for long term performance.
