Replace the Old House. Get the New Home Right From the Beginning.
A knockdown rebuild gives you the opportunity to create a home suited to your family, block and lifestyle without working around the limitations of the existing building. Your windows and doors are an important part of that opportunity.
They influence how much natural light enters the home, how rooms connect with outdoor areas, how effectively the house can be ventilated and how comfortable different spaces feel throughout Melbourne’s changing seasons.
Unlike a simple window replacement, a knockdown rebuild allows the window and door package to be considered as part of the complete home design. Opening sizes, window placement, glazing, frame systems, colours and door configurations can be reviewed before construction reaches the stage where changes become difficult or expensive.
Imperial manufactures custom aluminium windows and doors for knockdown rebuilds, new homes and architect-designed residences across Melbourne. We can work from your architectural drawings and window schedule to develop a coordinated package for the entire home.
Why Windows and Doors Should Be Planned Early
Windows and doors are sometimes treated as a later product selection; however, their dimensions, placement and performance can significantly influence your new home’s architecture, external appearance, comfort and everyday usability. Early planning allows you and your project team to carefully consider window orientation, natural light, cross-flow ventilation, privacy, street noise, opening sizes, indoor–outdoor connections, single or double glazing, frame styles and colours, flyscreens, security screens, hardware, locking options, energy-rating requirements, weather exposure, structural needs and installation requirements. Involving an experienced window manufacturer early can also help identify openings that may require an alternative frame system, glazing specification or door configuration.
Double-Glazed Windows for Melbourne New Homes
Comfort and Performance Beyond the Building Minimum
Double glazing uses two glass panes separated by a sealed space. When combined with a suitable frame and correct installation, it can reduce heat transfer compared with basic single glazing and support a more comfortable indoor environment.
Potential benefits include:
- Improved thermal performance
- More consistent internal comfort
- Reduced reliance on heating and cooling
- Better control of external noise when correctly specified
- Reduced internal glass-surface condensation under suitable conditions
- Compatibility with modern energy-efficient home designs
However, double glazing should not be treated as a single standard product. Glass thickness, coatings, pane combinations, air space, frame system and installation quality all influence the final result.
Imperial can review the window schedule and project requirements to help determine which systems and glazing options are appropriate for different areas of your home.
