When the glass unit mists up, this means that the seal has failed and is allowing moisture inside the glass unit. Unfortunately you can’t just wipe this away as the moisture is inside the unit and can’t be accessed.

Misting occurs when the seals in a glazed unit begin to degrade and can no longer protect the interior of the unit from moisture, dust and general grime. In a brand-new glazed unit, the seal is impenetrable and provides flawless protection for the gap between the panes. When this protection is compromised, it is only a matter of time before problems begin to present themselves.

Every property of every size, type, age and specification loses heat through its windows. In fact, a property’s windows are almost always the number-source of heat loss, which can have a detrimental effect on both energy use and heating costs. And while there’s a lot that can be done to help by way of heavier curtains, storm-strips and so on, you cannot expect to run an efficient home if you do not have fully-efficient windows.

It’s the million-dollar question every glazing company in the UK is asked day in and day out – is triple glazing really worth the money? It’s been around for some time and plenty of people swear by it, but is it really necessary to make the upgrade to triple glazing if you haven’t already?

Bring the question to any responsible glass suppliers and manufacturers in Stockport and they should all give you the same answer – it depends on the circumstances. There are certain instances in which triple glazing could make a big difference, though in others it may be advisable to stick with what you already have.
