Benefits of Triple Glazing
Why Upgrade Your Southampton Home?
- Significant Energy Savings: Triple glazing delivers superior thermal efficiency compared to standard double glazing, achieving ultra-low U-values. This design locks in heat, helping to lower your heating bills and keep your home comfortable, even during the coldest coastal winter snaps.
- Superior Noise Reduction: Enjoy a peaceful sanctuary by reducing external noise by up to 40dB with acoustic glass. Whether you live near the busy M27 corridor, under the flight path of Southampton Airport, or close to the bustling docks, our acoustic glass significantly dampens traffic and industrial noise for a quieter living environment.
- Enhanced Security: With a third pane of toughened glass and robust internal beading, our units act as a formidable deterrent against intruders. This extra layer of defence provides peace of mind that your home and family are well-protected.
- Condensation Control: Advanced insulation minimizes the “cold spot” effect on the internal pane, virtually eliminating condensation. This is vital in Southampton’s humid maritime climate, protecting your decor and reducing the risk of damp or mould on window sills.
- Weather Resistance: Our triple-glazed units are engineered to withstand the elements, ensuring your home stays draught-free and watertight, whether you face the strong winds from the Solent or heavy coastal rain.
- Increased Property Value: Upgrading your home’s EPC (Energy Performance Certificate) rating is a smart investment. High-performance windows make your property more attractive to future buyers in Southampton’s competitive property market.

u-Values - Thermal Performance
Not all triple glazing is the same. For maximum efficiency, the gap between the panes is just as important as the glass itself.
The Gold Standard: 44mm Units
Our premium option uses a massive 44mm sealed unit. This allows for two optimum 16mm cavities filled with Argon gas. This specification fits perfectly into our Sheerline Prestige, Residence 9, and Residence 7 systems, delivering centre-pane U-values as low as 0.5 W/m²K.
The Slimline Option: 28mm Units
Some window profiles cannot accept a 44mm unit. For these, we offer a 28mm triple glazed unit using Krypton gas. Krypton performs better in smaller gaps than Argon, allowing us to achieve excellent thermal performance (U-value 0.60) even in a slimmer profile. Beware this comes with a hefty price tag.

Contact UsImproved Security
Improved security over double glazed windows, due to the extra pane of toughened glass. Internally glazed windows offer added security and prevents the removal of the glass from the outside.
Sound Insulation
There is no major gain having triple glazing with three equal thicknesses of glass. The best solution would be with a thicker centre pane, please enquire for further information.
Heat Insulation
44mm sealed units filled with two 16mm cavities of argon gas. Argon gas is heavier than air, so acts as an insulator
Prevent Cold-Bridging
Warm edge spacer bars made from a composite material to stop the cold-bridge across the unit.
Low-emissivity Glass
Two coatings of low-emissivity glass (Low E). This is a microscopically thin coating that stops the heat from your house going outside.
Plenty of Options
Available in the Sheerline Prestige, Residence 9 and Residence 7 systems as a 44mm unit.

Frequently Asked Questions
Will triple glazing reduce noise from Southampton Airport and the docks?
Yes, significantly. Noise pollution is a common concern in Southampton, whether from flight paths over Swaythling and Bitterne, the M27 corridor, or heavy industry near the docks. Our triple glazing can be specified with acoustic laminated glass. This setup disrupts sound waves much more effectively than standard double glazing, reducing external noise by up to 40dB to create a peaceful home environment.
Is triple glazing suitable for Southampton’s coastal weather?
Absolutely. Being a port city, Southampton is exposed to strong winds from the Solent and higher humidity levels. Our triple-glazed units are designed to withstand these conditions. They offer superior weather sealing to prevent draughts during coastal gales and are built from durable materials that resist corrosion from salt air, ensuring they look good and perform well for years to come.
Do I need planning permission specifically for Southampton properties?
For the majority of residential homes in Southampton—including the suburbs of Bassett, Shirley, and Totton—replacing windows is considered “Permitted Development” and does not require planning permission. However, if you live in a designated Conservation Area (such as Oxford Street or the Polygon) or a Listed Building, you will likely need consent. We recommend checking with Southampton City Council, and our team can assist with compliance.
How does triple glazing help with condensation in a maritime climate?
Southampton’s humid maritime air can often lead to condensation issues in winter. Triple glazing is the most effective solution for this. The internal pane of glass is shielded by two gas-filled cavities, keeping it close to room temperature. This eliminates the “cold spot” where moisture condenses, keeping your windows dry and significantly reducing the risk of damp or mould forming on your sills.
Is triple glazing a good investment for a Southampton home?
Yes. Improving your home’s energy efficiency is a smart financial move. Not only does triple glazing lock in heat to lower your utility bills, but improving your EPC (Energy Performance Certificate) rating also makes your property more attractive to buyers in Southampton’s competitive market. It adds both immediate comfort and long-term value to your property.
