Triple glazing is often marketed as the ultimate upgrade but is it always necessary? For many homeowners, the answer depends on the property, location, and how the home is used.
Understanding the Difference
Double glazing uses two panes of glass with a sealed insulating gap, while triple glazing adds a third pane for additional insulation. This can improve thermal performance, but the gains aren’t always dramatic in every situation.
When Triple Glazing Makes Sense
Triple glazing can be beneficial if:
- Your home is in an exposed or rural location
- You experience significant heat loss through large window areas
- Noise reduction is a priority
- You’re aiming for the highest possible EPC rating
In these cases, the extra insulation can improve comfort and reduce energy demand.
When High-Quality Double Glazing Is Enough
For many UK homes, modern A-rated double glazing provides excellent performance:
- Strong thermal insulation
- Reduced draughts and condensation
- Better value for money
- Slimmer frames and better light transmission
In typical urban or suburban homes, the difference between premium double glazing and triple glazing may be marginal.
The Right Choice Is About Balance
Admiral Homespace helps homeowners choose glazing based on real-world performance not just headline specs ensuring comfort, efficiency, and value without unnecessary cost.

‘Over the years and in different properties I have had doors and windows replaced using the usual companies you see advertised on TV. Most of the work if not all was done
to about 70% satisfaction. The installers were contracter’s that had no commitment to what they were doing and it showed. We needed a new set of patio doors, thinking here
we go again going to get another job done that I know I won’t be overall happy with. I passed Admiral Homespace by chance, popped in had a chat with one of the sales team
who was not a cheesy sales guy in fact nice and pleasant to talk with (good start). We arranged a site visit he came over I explained what I was after which was to limit the
amount of surround and centre join of the doors he offered me a new to the market product that gave a centre join of 20mm and minimal surround. To cut a long story short,
bought the product it has been fitted by an excellent team who are employed with the company so have vested interest in doing a good job which they did. overall from sales
to surveying to organising and fitting the whole team are excellent very professional and actually care, the fitters Andy & Wayne look genuinely pleased with the doors and the
fact I was so pleased. I would highly recommend them looking to get new windows fitted so am going back to them. Happy to pass on pictures to them to forward to potential
customers’

Great After Sales Support!
Admiral installed our doors and windows in 2012. In 2026 our front door lock broke and the manufacturer didn't make them anymore nor had any spare parts !
Nadine and Andy road to our rescue. Andy researched a potential fix, Nadine ordered the parts and Andy promptly repaired our lock mechanism and then installed it back in the door.
Absolutely super service and support - even years after our initial install!

The customer service was really good when I made my initial enquiry and I felt like the company prided itself on that. I had several questions which were answered promptly
and professionally and customer service is really important to me, particularly when I'm making a substantial purchase. I had a slight issue with the lock on my door and an engineer visit was arranged quickly and efficiently. The matter was resolved in a few minutes with a few adjustments. Very happy with the service.’

Admiral Homespace built and supplied the wooden windows and patio doors for our new Garden Room. They were built to a high standard and, working with our main contractor, adjusted to accomodate design changes as went along.
Installation went well and we are very happy with the result.
I'd definitely recommend Admiral Homespace to anyone looking for custom, handmade windows & doors for their project.

I used Admiral to have new conservatory, windows and doors fitted at my previous address. I was very pleased with the results so chose them to do the work when I moved house. I am delighted with my new glass conservatory roof. it’s made the room look bigger and brighter and much more inviting. Excellent customer service from start to finish, with Stuart, Nadine and Dave making the whole process smooth and stress-free. Highly recommend!’
