Insulglass® units are an excellent choice for window insulation and provide home owners and builders a cost effective way to achieve superior energy ratings.

On an average home, 49% of heat loss and 87% of heat gain is through the glazing. Comfort at home depends on the effective window insulation as well as ceiling and wall treatments. As part of the overall program of envirosmart building materials, energy efficient windows minimize the need for artificial climate control. The use of Insulglass units reduces heat transfer through the window by over 50%.

An Insulglass unit is made to customized sizes and specifications. An aluminium spacer, creating the gap between the 2 panes of glass is cut and bent onsite, and this is then filled with a dessicant which acts as a drying agent. The units are then hermetically sealed with a dual  polyisobutelene and polysulphide as a sealant to provide durability. Argon or air is used to insulate the unit, then sealed. The glass used can be tailored to suit your requirements by utilising different glass products in the make up such as tints, performance tints, reflective, Low E, laminated glass, obscure or toughened. 

How do Insulglass units work?

Glass on its own is a poor insulator, allowing heat to transfer at a high rate. However, Insulglass units provide insulation as the layer of air or argon sealed between the 2 panes of glass is a very good insulator. The larger the gap between the 2 panes of glass, the greater the insulation you can achieve.

IGU's are able to provide insulation, passive solar heat gain, solar heat reduction, safety, privacy, noise reduction, natural light, views and all of this while improving the comfort of your home or building.

Points to Note:

Condensation

As we heat or cool our home or building, we increase the risk of condensation. This is formed when warm moist air comes into contact with the colder surface of glass giving the appearance of moisture. When using Insulglass units condensation is significantly reduced as the inner pane remains substantially warmer than when using single glazing.

Cleaning & Handling

Insulglass units require additional care when handling, installing and cleaning. Please click here for a copy of our cleaning and handling recommendations.

Installation & Glazing

A high percentage of IGU’s fail due to improper glazing techniques. It is most commonly characterized by the appearance of moisture inside the unit. The glazing system must be designed to drain out all the water in the rebate to ensure water isn’t trapped against the edge of the glass, causing exposure to the sealant or desiccant.

Thermal Stress

All performance glass may also be subject to thermal stress, and we recommend a thermal assessment analysis is carried out. This assessment considers glass type, frame type, glazing method. To confirm if the glass selected for your project is at risk of thermal stress, please complete the attached questionnaire, and fax to (03) 9730 7488.

Low E Coating

Low E products have a special coating that provides thermal and solar properties, and therefore does not have the same appearance or surface as regular float glass. A small degree of haze may be observed under certain light conditions if this glass type is used in your unit.

Insulblind
Insulblind is an integrated system that seals blinds permanently in a double glazed cavity.  These units are completely UV stable and protected from dust, dirt and moisture.
Product benefits include:

• Blinds stay new, clean and protected from damage.

• Lower air conditioning costs through controlled blocking of infrared light.

• Reduced fading of furnishings and fabrics through UV protection.

• Manual operating system to tilt, raise and lower blind.

• Fully motorized system to tilt, raise and lower blind.

 Insulblind is a must for commercial projects such as hospitals, motels and special accommodations.
