However, if there is direct summer sun striking the glass, then external shading is the appropriate solution. Brand new double glazed windows are much more expensive than secondary glazing. There is also a considerable amount of effort involved in selecting, arranging, installing, plaster repair, painting and cleaning up afterward. With replacement windows, the old heavy windows also need to be removed and properly disposed of.
Tradesmen need to install the new windows carefully and the architraves and plaster around each window replaced or repaired. It can be challenging to co-ordinate multiple tradespeople in a timely manner when trying to get your home back to normal. Also, we often we hear that people are disappointed to find that their brand new double glazing does not allow the adequate still air space to deliver the comfort they paid for.
No other structural changes or managing tradespeople is required. Your home is left clean and tidy with seamless secondary glazing that provides perfect still air space. There are a number of glazing companies that provide this service. Please be mindful that your original window frames were designed for a single pane of glass and are weighted to allow them to open and close normally. So there are two issues with replacing the glass:. Its design provides the best possible still-air space to maximise thermal performance.
Argon filled double glazing is one of the most expensive types of double glazing available. Believe it or not, no glazing is vacuum sealed because it would put the two panes of glass under pressure and eventually the two panes would touch.
Factory fitted double glazing is hermetically sealed, meaning that no air can enter or escape. The level of conduction of heat is measured by a number called a U-value. The lower the U-Value, the better the performance of the glazing. The U-value of a 3mm single glazed window with aluminium frame is 6. Compare this to a double glazed unit, with 6mm spacing and aluminium frames, with a U-value of 3. Secondary glazing retrofit double glazing works the same way as factory made double glazing by providing a layer of still air that improves the insulation value of otherwise highly conductive glass.
In factory made units you have the opportunity to select many glass treatment options and also a gas fill. These units are hermetically sealed and have desiccant in them to absorb any water vapour that may impregnate the seals.
It relies on the water vapour in the air not being so high as to create condensation in the air space. This means that of all of the Melbourne-based installations we have carried out, there have been no reports of a moisture problem. There have been two homes at altitude above metres , that have a minor problem with misting.
The misting is insufficient to condense and it dissipates during the day. Secondary Glazing vs. Double Glazing…. No mess. No landfill. The appearance, character and function of the window or door is not compromised.
How does secondary glazing work? The benefits of secondary glazing…. How do I get started? STEP 3: Arrange a visit for a quote and a check measure. There is a range of glazing options available. It is possible to convert single- pane windows to double - glazing. Retrofit double - glazing , usually made out of PVC or acrylic laminate, is applied to your existing single- pane windows to effectively turn them into double - glazed windows.
Another method is through an acrylic insert held into place by magnets. The disadvantages of double glazed windows are: Can't be repaired. The space between the two panes of glass traps air, forming a layer of insulation. If the seal isn't airtight, condensation will appear between the panes. Seal your windows and stay comfortable when there's a chill in the air.
Curtains Like Warm Blankets. Roll Out the Shrink Wrap. Drop Your Storm Windows. Use More Bubble Wrap. To double glaze an existing window, all you need to do is to add another layer of glazing.
This is done by installing a discreet sub frame on the inside of the window, to which an optical grade acrylic panel is fitted and held in place by continuous channel magnets.
Retrofit alternatives to double glazing installing a new double glazed glass unit into the existing sash. Silicone caulk provides a solid seal for window glazing when properly installed.
This eliminates the chances of water seeping past the silicone glazing and destroying the newly installed pane of glass. Silicone caulk seals and secures glass in a window frame. Triple glazing obviously has an extra pane of glass, so each triple glazed sealed unit is thicker and heavier than double glazing , putting more strain over time on window hinges. Casement windows are generally the cheapest option, contrary to the dual turn which is considered to be most expensive. Argon is an inert gas found in our atmosphere.
When your windows are filled with Argon , there is a slightly higher efficiency rating of the window. But you might not get the outcome you are looking for unless you consider all the associated implications.

The windows in this unit were typical of many dwellings from the s.
