Double Glazing Or Triple Glazing - Which Does Your Home Need?


Window buyers have never had as much choice as they have nowadays, and there’s certainly lots of choice at James Oliver, where we supply double and triple glazed window solutions. 

Heritage Windows

This poses customers with a question, namely, “which am I best buying for my home, double or triple glazed windows?”

It’s a toughie, that’s for sure! A bit less so though perhaps if you know more about what both options have to offer. 

James Oliver can fill you in with info about that:

Energy efficiency

To identify the standard of thermal efficiency delivered by a double or triple glazed window, just look to see what its U-value is – the lower the U-value, the better its thermal performance. 

You can anticipate a U-value of around 1.0 W/m²k from an average, standard UPVC triple glazed window, which is largely 40% more thermally efficient than a usual A-rated window. If you opt for new windows from our EXTREME range, they will come A+ energy rated as standard.

Soundproofing

When promoting their triple glazed windows, some suppliers say that they are good for reducing the impact of external noise in the home. That can be true, but a window must be specified in a certain way for it to provide effective, and noticeable soundproofing.

The three panes must all be of varying thicknesses, and so must the cavities. Use the same thickness throughout for both, and they’ll have little or no effect.

Security

A window upgrade should lead to a more secure home. Double and triple glazed windows both have robust frames, and the security features within them help to keep the windows firmly closed shut when locked.

The multi-point lock is virtually unbreakable and tamper-proof, and most double and triple glazed windows are internally glazed, stopping any glass panes from being removed from outside. For obvious reasons, having three glass panes, as opposed to two, gives you added protection from intrusion. 

Price

Though triple glazed generally costs more than double glazing, you’re likely to get a greater return from it via the energy savings you make over the lifespan of the windows.
