Windows the Great Escape Route for Warmth in the Home

Heat loves an easy exit. After the roof, windows are the next great escape route for warmth. Plain glass is a poor insulator, so heat slips out in winter and barges back in during summer. That is why upgrading the glass and frames delivers one of the biggest comfort and energy wins in a New Zealand home.

What we do at Ryan Double Glazing

Ryan Double Glazing specialises in double glazing existing aluminium joinery. We simply remove the old single panes and fit sealed double glazed units into your current frames. No major demolition, no full window replacement, just a smart retrofit that brings year-round comfort and a house that feels quieter, warmer and drier.

Why double glazing works

Double glazing is often called window insulation. Two panes of glass with a sealed air or gas layer in between form a thermal barrier. That gap slows heat transfer, so winter warmth stays inside and summer heat is reduced. The result is lower energy use and the potential to save money on heating bills while making rooms more comfortable.

Frames matter as much as glass

If you choose aluminium frames, look for a thermal break in the profile. This separates the indoor frame from the outdoor frame to cut down heat loss and reduce the risk of condensation on cold mornings. Other framing materials such as uPVC or timber also perform well when insulation is the priority. We assess frame condition and recommend the best approach for each opening, including hardware upgrades and draught control.

Double versus triple glazing

Double glazing suits most Bay of Plenty homes and delivers excellent gains in comfort and condensation control. In specific cases where noise control or extreme exposure is a concern, triple glazing can add another layer of performance. We will explain the trade-offs in weight, cost and frame suitability so you can choose with confidence.

Humidity, ventilation and real-world comfort

Good ventilation helps, but it must be timed to conditions. On a dry winter morning, briefly airing a room can remove humid indoor air so the space heats more efficiently afterwards. When the outside air is very damp, throwing windows wide may add moisture rather than remove it. Double glazing reduces cold surfaces, which in turn reduces condensation risk, but smart ventilation and extraction in kitchens and bathrooms still play a key role.

Secondary glazing for specific situations

If full retrofit double glazing is not practical for a window, secondary glazing can be a useful step. Options include clear acrylic panels, magnetic systems or an additional pane installed on the interior face. When well fitted and sealed, these solutions can substantially improve comfort and reduce draughts. We can advise where secondary glazing makes sense alongside full double glazing elsewhere.

Dress the glass for maximum effect

Glazing is the first line of defence. Curtains and blinds are the second. Well-fitted, floor-length, lined curtains on tight tracks can further reduce heat loss overnight. In sun-exposed rooms, light-coloured linings help manage summer heat, while daytime opening allows welcome winter solar gain.

Coping with Tauranga conditions

Coastal air, salt spray and bright summer sun are part of life from the Mount to Papamoa. We specify glass types and edge seals suited to these conditions, along with spacer systems and sealants selected for durability. For north- and west-facing rooms, solar control or low-E glass can cut glare and reduce overheating while protecting furnishings from UV fade.

The upgrade pathway

1. Assessment

We measure each window, review frame condition, sun and wind exposure, and discuss your comfort goals.

2. Specification

Glass type, spacer, gas fill and thermal break requirements are matched to room-by-room needs.

3. Retrofit installation

Old panes out, new sealed double glazed units in, with careful sealing and tidy finishing.

4. Finishing touches

Optional hardware refresh, draught control trim and advice on curtains or blinds to complement the new glazing.

5. Enjoy the results

Warmer winters, cooler summers, reduced condensation and a quieter home.

Why act now

• Comfort: warmer, more even temperatures across the day.

• Energy: less heat loss means lower running costs.

• Health: fewer cold surfaces reduces condensation and helps keep mould at bay.

• Value: a desirable upgrade for buyers focused on efficiency.
