Low emissivity (Low-E glass) is a critical component of high performance energy efficient windows. This glass has unique coating that allows the passage of short wave solar energy into a building but prevents long-wave energy produced by heating systems and lighting from escaping outside. Low-E glass allows light to enter while also providing thermal insulation.

There are two types of Low-E products : Hard coat and Soft coat

The Glassroom provides Low-E glass products suitable for any climate. The transparent coating is applied using patented technology during the glass making process while the glass is still semi molten. The result is highly durable hard coating that is permanently bonded in the glass surface. Unlike ordinary glass, Low E products provide insulation that keeps your home or building warm in the winter by reflecting heat back into the room, and cool in summer by reflecting the sun’s heat back through the glass to the exterior. The enhanced insulation performance of these products reduce the need for heating and cooling, resulting in energy savings all year round.

Why Should I Choose The Glassroom to double glaze my timber window frames?

The Glassroom’s Retro-fit system creates a unique dry glazing system for double glazing to your existing timber windows and doors in your home.

According to the Department of Building and Housing, in a well-insulated building, windows and other glazed areas are the biggest source of heat loss. The installation of a double glazed unit effectively halves the heat loss when compared to a single-glazed window of a similar shape and size.

Glazing is an important consideration when renovating or building. The correct glazing choice can ensure you are creating a more comfortable, sustainable environment suitable for both hot and cool weather. In some areas of New Zealand, double glazing can be used to meet the new H1 requirements.

Insulation is becoming increasingly important in building and renovation; however heat loss due to inefficient or outdated glazing can mean that your insulation will be ineffective and less cost effective. Different types of glass are required for different environmental conditions. Our unique retrofit system is designed around an already existing and highly effective double glazing solution and guarantees that a range of high tech double glazing units can be installed.

Our system is designed specifically for New Zealand wooden joinery and can be used in a number of configurations.

The Glassroom’s Glazing system allows you to maintain the original character aesthetic of your home while adding value to your property and saving money on energy costs.

With specialist skills in lead light and heritage glass, we have the ability to introduce modern thermal technology whilst maintaining the character and quality associated with New Zealand’s building heritage.
