Why Double Glazing?

Double glazing minimises heat loss through your windows by providing an insulated layer for your home.

We specialise in retrofitting new double glazed units on to existing aluminium or timber joinery.

Warmer Living

Double glazing keeps out cold air and retains warm air inside the house resulting in a warmer, healthier and drier home all year round.

Reduced Condensation

The insides of the windows will have significantly reduced condensation resulting in drier window sills with longer lives.

UV Protection

Reduced Power Costs

Added insulation results in more moderated temperatures throughout your house reducing the energy bill required to heat your house.

Reduced Noise

The extra thickness and gap between multiple panes of glass will help shut out outside noise from the road or the neighbours.

Reduced UV rays will mean that the harsh rays of the sun will not damage your family's skin or the furniture around your household.

Increased House Value

For most people, their home is their greatest asset and adding double glazing will increase the value of your home.

Double Glazed Units

We order custom double glazed units for your property from our supplier Stake Glass who are a major glass manufacturer based locally in Christchurch. Double glazed units consist of two panels of glass which are sealed together with a space filled by Air or Argon gas.

There are different grades of double glazed units:

Double Glazing (Air)
Double Glazing (Argon)
Double Glazing (Argon + Low-E Coating)

As you progress down the list, there is an increase in the material cost of the glass but the performance is substantially improved with the addition of Argon gas and the Low-E Coating. Other companies charge a premium to obtain the highest specification double glazed units with both Low-E and Argon gas but we offer this standard with all our quotes as the difference in performance is huge. This is further explained below in the U-Values section.

U-Values

Low-E glass has a thin, almost invisible coating which lets sunlight in but reflects heat to optimise thermal efficiency in your house. This allows for warm air to stay inside the house on cold evenings and reflects warm air back out during hot days.
