Property advice: Is there any merit to spending money on triple glazed windows?

With options including double and triple glazing as well as wood, aluminium or aluclad frames — how do I choose what kind of windows to use on my new extension?

Kieran McCarthy: "I would be tempted to upgrade your patio door to a sliding aluminium or modern timber type door. And due to the width and the weight of the triple glazing I would push for a ‘lift and slide’ option."

Hi Kieran,

I’m proposing to build a single-storey, full-width rear extension to a typical three-bed semi (built 1995) that would just be under planning requirement and will involve the demolition of an existing half width sun room (added in 1999). I have occupied the house from day one.
