Benefits of Triple Glazing
Why Upgrade to Triple Glazing?
- Significant Energy Savings: Triple glazing offers superior thermal efficiency compared to standard double glazing, achieving ultra-low U-values. This keeps your home warmer during Hampshire’s chilly winters and helps combat rising energy prices.
- Superior Noise Reduction: Reduce the impact of outside noise by up to 40dB with acoustic glass. Whether you live near the M3 or M27, under the flight path of Southampton Airport, or in a busy town centre, triple glazing creates a peaceful, quiet sanctuary.
- Enhanced Security: With a third pane of toughened glass and internally beaded frames, our windows provide an extra layer of defense, deterring intruders and keeping your family safe.
- Condensation Control: The improved insulation reduces the “cold spot” effect on the inner glass pane, virtually eliminating internal condensation and the risk of damp or mould build-up.
- Weather Resistance: From the coastal gales in Portsmouth and Southsea to the rural elements of the New Forest, our triple-glazed units are built to withstand the diverse local weather conditions.
- Increased Property Value: Improving your home’s EPC (Energy Performance Certificate) rating makes your property more attractive to future buyers across the county.

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
What is triple glazing and how does it work?
Triple glazing is a type of window or door that features three panes of glass, providing superior insulation and energy efficiency. The three panes of glass are separated by gaps, typically filled with a gas such as argon or krypton, which helps to reduce heat transfer and prevent heat from escaping.
How much do triple glazed windows cost?
As a rough guide triple glazing will cost on average around £150 extra per window over double glazing, based on one square metre of glass. This would be the average window size of a 1.2m square (4ft) UK window as it would have around one square metre of glass.
Are triple glazed windows better than double glazing?
While the initial cost of triple glazing windows may be higher than double glazing, the long-term savings in energy bills make it a cost-effective choice. Triple glazing windows significantly improve the energy efficiency of your home, reducing heat loss and thereby lowering your heating costs.
What do triple glazed windows do?
For a long time windows in the UK were single glazed, in the 1980’s double glazing really took off. Back in the day the best double glazed window had a u-value of around 3 w/m²k. The glass units were made of two panes of normal glass with a metal spacer holding them apart. Triple glazed windows have changed the thermal performance hugely.
Today, the units are manufactured with three panes of glass, two of them will have a low-e coating, the gaps between the panes are filled with an inert gas commonly argon. Finally the triple glazed unit will have two warm edge spacers that stop cold transferring through the edge of the glass. This will normally reduce the overall whole window u-value down to less than 1 w/m²k. Do remember all triple glazing is not the same, generally with argon filled units, the gaps between the panes should be 16mm, any smaller and the efficiency will be less.
Are smaller triple glazed units available?
We can offer 28mm triple glazed units (2 x 8mm gaps) filled with krypton gas and 3 layers of 4mm glass, which achieves a centre pane U-value of 0.50 W/m2K. We offer this smaller unit to accommodate for the smaller units that we offer and for our customers who prefer the bead detail on the 28mm system. Krypton gas works better on smaller air-gaps than argon, but is MUCH more expensive than argon filled units. Either way KJM can provide a triple glazed unit to suit your requirements.
