When installing new windows, choosing the right method is just as important as selecting the window itself. The correct installation ensures durability, energy efficiency, and protection against Australia’s changing weather. In most Australian homes, there are two main installation methods: Timber Reveal and Subsill & Head. The choice depends largely on your wall type.

‍

Timber Reveal: Ideal for Timber Frame Walls

‍

Definition

‍
Timber Reveal is designed specifically for timber frame houses. A timber surround is added around the window, creating a transition layer that allows the frame to fit tightly into the wall.

‍

Installation Features

‍

Timber walls are light and easy to process, making installation simpler.

The timber reveal ensures a close fit between frame and wall, improving sealing and stability.

It suits small-scale homes and traditional wooden houses.

Installation is relatively fast and cost-effective.

‍

Advantages

‍

Excellent sealing performance

Simple installation process

Retains the architectural style of timber homes

Affordable solution

‍

Common Regions

‍
Timber Reveal is widely used in Melbourne and Victoria, where many homes are timber-framed. In small villas and cottages, this method is especially popular because it blends with the existing style.

‍

‍

Subsill & Head: Best for Solid Walls

‍

Definition

‍
Subsill & Head installation is designed for solid wall structures, such as double brick, concrete, or cement walls. It includes a subsill (window base) and a head (window top), which provide extra support and drainage.

‍

Installation Features

‍

Solid walls are thicker and heavier, requiring extra support.

The subsill and head strengthen the window frame.

The system prevents water from pooling and leaking into the wall.

Suitable for modern homes that need stronger weather resistance.

‍

Advantages

‍

Added structural strength

Effective drainage system

Excellent protection against water and moisture

Long-term durability for solid walls

‍

Common Regions

‍
This method is common in Sydney, NSW, and other regions with many brick or concrete homes. Double brick construction is especially popular in these areas, making Subsill & Head the mainstream installation system.

How to Choose the Right Method

‍

Timber frame walls → Timber Reveal

Double brick, concrete, or cement walls → Subsill & Head

Using the wrong method may reduce sealing, weather resistance, and lifespan. Always match the installation to your wall type.
