Bring your home up to modern standards with expertly installed double glazing


Once you’ve insulated your ceiling, floors and walls, the next biggest culprits for heat loss are windows and glass doors.

Today, new builds and renovations require double glazing to comply with the New Zealand Building Code. National Glass Rotorua can install quality double glazing as part of your new build project to ensure your new home remains warm and dry for many years to come.

Our team is also experienced in the installation of retro-fit double glazing to older homes using Low-E glass which is designed to improve heat retention inside the home. We can visit your property and offer you a quote for some or all of your windows.

As an established company offering professional glazing services across the central North Island, National Glass Rotorua has your needs covered for double glazing and a wide range of other areas including glass repairs and replacements and installation for glass balustrades and glass splashbacks.

Five benefits of double glazing


Improved energy efficiency:
In double glazed windows the additional layer of glass acts as insulation, reducing heat transfer between the interior and exterior of a building. This helps maintain a more stable indoor temperature, leading to reduced heating and cooling costs. By reducing the need for heating and cooling, double glazing can contribute to lower energy consumption and, consequently, a smaller carbon footprint.

This is beneficial for both the environment and the homeowner's long-term energy costs.
Enhanced insulation:
Double glazing provides better insulation against external temperature fluctuations. This provides a more comfortable living or working environment as it helps to minimise drafts and temperature variations inside the building.

Noise reduction:
Double glazing can significantly reduce external noise levels. The additional layer of glass helps to dampen sound transmission, creating a quieter indoor environment. This can be particularly beneficial for homes located in busy urban areas or near noisy roads.
Condensation control:
Double glazing helps to minimise condensation on the interior surface of windows. This is especially important in colder climates where condensation can lead to mould growth and damage to window frames.
UV protection:
The extra layer of glass in double glazing can provide increased protection against harmful ultraviolet (UV) rays. This helps prevent fading of furniture, carpets, and other interior furnishings caused by prolonged exposure to sunlight.
