You look at the price tag. Then you look at the window.
It looks exactly the same as the double glazed one next to it.
So why pay the extra?
The Noise
Forget the heat for a minute. The big difference is the sound.
Round here, traffic is a nightmare. Anyone near the Wessex Way or Castle Lane knows the drone never stops.
Double glazing dulls it. Triple glazing kills it.
That third sheet of glass just shuts the world out. The house goes properly silent.
The “Cold Spot”
Touch a standard window in February. It’s freezing.
That cold surface creates a draught. It runs right across the floor.
Triple glazing doesn’t do that.
The inside pane stays warm. Sit your sofa right next to the glass. You won’t feel a thing. No chill on your neck. No draughts.
The Numbers (U-Values)
The U-Value is just the score for heat loss.
Old single glass: 5.0 (Rubbish)
Standard double: 1.2 (Standard)
Triple Glazing: 0.8 (Passive House standard)
That 0.8 is the target. It keeps the heat in the lounge.
The Verdict
Quiet street? Save your money. Standard double glazing is fine.
Busy road? Cold lounge? It is the only way to go.
Come down to 78 Alma Road. We have a sample unit. Knock on the glass yourself. You can hear the solid “thud” compared to the hollow sound of a standard window, or give us a call on 01202 533126.
