Why Double Glaze?
Your Windows Are Costing You More Than You Think
Single-glazed aluminium windows — common in most NZ homes built before 2000 — are one of the biggest sources of heat loss, noise and condensation. Upgrading to double glazing is one of the highest-return improvements you can make to a NZ home.
Warmer in Winter
Double glazing reduces heat loss through windows by up to 50% — keeping your home warmer for less energy and cost.
Cooler in Summer
The insulating air gap also keeps heat out in summer — reducing reliance on heat pumps and air conditioning.
Quieter Home
Double glazing significantly reduces external noise — particularly valuable on the Kāpiti Coast near roads or the coast.
No More Condensation
Cold single-glazed windows cause condensation that leads to mould, rot and health issues. Double glazing eliminates this.
Higher Property Value
Double glazed homes command higher sale prices and are increasingly expected by buyers across the Wellington and Kāpiti market.
Lower Energy Bills
Reduced heating and cooling costs mean double glazing pays for itself over time — especially at just 1% finance.
