Benefits of Triple Glazing

Why Upgrade Your West London Home?

  • Significant Energy Savings: Triple glazing delivers superior thermal efficiency compared to standard double glazing, achieving ultra-low U-values. This is essential for the many Victorian and Edwardian properties in Twickenham and Richmond, locking in heat to lower bills and keeping drafty period homes warm.
  • Superior Noise Reduction: Enjoy a peaceful sanctuary by reducing external noise by up to 40dB with acoustic glass. This is the ideal solution for West London residents living under the Heathrow flight paths or near busy routes like the A316 and South Circular, significantly dampening overhead and traffic noise.
  • 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 in these affluent boroughs.
  • Condensation Control: Advanced insulation minimizes the “cold spot” effect on the internal pane, virtually eliminating condensation. This helps protect the interior decor of your home and reduces the risk of damp or mould developing on window sills—common in older river-side properties.
  • Weather Resistance: Our triple-glazed units are engineered to withstand the elements, ensuring your home stays draught-free and watertight, whether you face the winds coming off the Thames or heavy urban showers.
  • Increased Property Value: Upgrading your home’s EPC (Energy Performance Certificate) rating is a smart investment. In the competitive West London property market, high-performance windows make your property significantly more attractive to future buyers.

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.

Improved 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.
