Aluminium Windows and Doors, Double Glazed Doors and Windows, Double Glazed Windows and Doors South Australia, Double Glazed Windows and Doors Manufacturer Australia

Aluminium Double Glazed Windows and Doors Manufacturer Australia

Nautilus Pacific Windows provide an amazing range of Commercial Grade Thermal Break and Thermally Enhanced Double Glazed Windows and Doors to suit every domestic and commercial requirement.

Double Glazed Windows provide significant reductions in heating and cooling costs. Recent surveys show up to 50% of household energy is lost through single glazed aluminium windows and doors. Nautilus Pacific Windows and doors perform 3 times better than standard aluminium frames.

Nautilus Pacific Windows and doors have been designed with both functionality and aesthetics in mind. Windows can be opened in multiple configurations, provide superior security and come in a wide range of both traditional and contemporary finishes including marine grade. Double-glazing your home can provide massive reductions in outside noise levels; up to 44db of reduction can be achieved (industrial ear muffs provide only 33db) making Nautilus Pacific Windows and Doors perfect for busy roads and noisy flight paths.

What’s in Between

Because the space between the panes in double glazed windows is fully sealed, it acts as an insulator, limiting the transfer of cold air coming into your home. Thermal and acoustic performance can also be increased when argon gas fills this space. Nautilus Pacific Double Glazed Windows and Doors are argon filled as standard.
Double glazed units include a spacer which is a metal or polymer strip that separates the two panes of glass. Typically, spacers contain a desiccant (drying agent) to remove moisture trapped in the air space.

The Benefits of Double Glazing

Double glazed windows are an ideal energy efficient choice with the added benefit of minimising noise.

  • The sealed argon filled gap between the two panes acts as an added layer of insulation.
  • This added thermal and acoustic resistance reduces the amount of heat escaping in winter and keeps your home or office at a more comfortable temperature.
  • Double glazing has the reverse effect in summer, preventing unwanted heat from coming into the home or office.
  • This extra insulation lessens your reliance on artificial heaters and air conditioners and can provide up a 30% reduction to your heating and cooling costs.
  • Double Glazed Windows are considered a safer option when compared to standard single pane windows. Two sheets of glass are a lot harder to break than one and for even greater security you can specify toughened or laminated glass.

What to Look for

Amount of space between panes

  • Nautilus Pacific Windows typically use a space of 9 to12mm, which is recommended for optimum thermal performance. Glass thickness is typically 5mm, but thicker glass can be specified, as well as low-e, laminated and even bullet proof glass.

What’s in between?

  • Because the space between the panes in double glazed windows is fully sealed, it acts as an insulator, limiting the transfer of cold air coming into your home.
  • Thermal and acoustic performance can also be increased when gas fills this space. The most popular gas used is argon which has low conductivity properties to improve insulation. All Nautilus Pacific Double Glazed Windows and Doors are argon filled.
  • Double glazed units include a spacer which is a metal or polymer strip that separates the two panes of glass. Typically, spacers contain a desiccant (drying agent) to remove moisture trapped in the air space.

Type of glass used

  • A wide range of different glass types such as low-e and laminated, can be used in double glazing units to further increase energy efficiency and noise control.
  • Low-e glass will further reduce the amount of heat escaping while thicker laminated panes disrupt sounds waves to improve acoustic performance.

Frame and Glass Options

Nautilus Pacific Double Glazed Windows and Doors offer two frame options.

Typically, these frames have cross section of 50 to 80mm, with toughened 5mm glass and an argon filled gap of 9mm; and

Thermally Enhanced Frames

Thermal Break Frames

These frames have a typical cross section of 68 to 150mm, with toughened 5mm glass and an argon filled gap of 12mm, ensuring maximum thermal and acoustic performance. Windows and doors need to be considered as a whole unit.

The framing material you choose to complement your glass may enhance its performance or in some cases reduce its energy efficient properties. Standard aluminium window frames readily conduct heat and cold and if not thermally enhanced, may eliminate any benefit from installing expensive double glazing. How well the cavity is sealed and the type of spacer used is also an important factor to consider. If the double glazed unit is not sealed properly or if the spacer does not contain adequate desiccant, it can reduce performance and condensation will appear on cold surfaces.

What is U-value?

U-value measures how well a product prevents heat from escaping. It is a measure of the rate of non solar heat loss or gain through a material or assembly. U-value ratings generally fall between 2.0-10.0 W/m2K for Australian products. The rate of heat is indicated in the terms of the U-value of a window assembly which includes the effect of the frame, glass, seals and any spacers. The lower the U-value, the greater a window’s resistance to heat flow and the better its insulating value.

U-Value for our Thermally Enhanced Windows and Doors: 2.8W/m2K

U-Value for our Thermal Break Windows and Doors: 2.5W/m2K

Why is Solar Heat Gain Co-efficient (SHGC) Important?

SHGC measures how well a product blocks heat caused by sunlight. The SHGC is the fraction of incident solar radiation admitted through a window, both directly transmitted, and absorbed and subsequently released inward. SHGC is expressed as a number between 0 and 1. The lower a window’s SHGC, the less solar heat it transmits.
