Acoustic Windows and Doors Secondary

Installation of Secondary Double Glazed Windows for Renovations and Refurbishment

Sometimes it may not be possible to replace old windows and doors at your discretion, such as when the building is heritage listed and the owner is required to maintain the period features outside or when body corporate/council permission must first be obtained because any new double glazed windows and doors should match all other windows. In practice, customers are rarely rejected such quality, value added improvements, especially when the existing windows are deemed unsafe, but appropriate permissions can take months and considerable effort. For customers who do not want to go through this trouble, one of the solutions is to install secondary windows.

Other clients are referred to Double Glazed Windows and Doors for secondary glazing by energy efficiency consultants and acoustic engineers, because secondary glazing is extremely effective in insulating your home against heat, cold, wind, water and noise. Essentially, secondary double glazing will mimic the benefits of triple glazing, but with a wider air-gap, creating the ultimate environment for absolute luxury and comfort.

The only condition for secondary glazing is at least 50mm wide interval from your existing windows to the start of the wall or if you have a windowsill with minimum 50mm wall space on the side. If in doubt, feel free to send us pictures, photographs or we can arrange for a surveyor to visit you for a free consultation.

Installation Process

When installing secondary double glazed windows, existing windows are retained. Double Glazed Windows and Doors' installers do not remove existing windows during the secondary window installation.

Tools Required:

• Gloves, Goggles
• Tape Measure, Spirit Level, Pencil
• Electric screwdriver
• Hand Drill, with 3, 3.5 or 4mm drill bits
• Screws see below for sizes
• Any type of Saw (to cut an aluminium angle)
• Expanding foam
• Window Packers - 1, 3, 7, 12mm

Fitting Secondary Double Glazed Windows and Doors

Window insertion involves fitting the window in the aperture, which is a two-stage process. The first stage involves levelling the window horizontally and applying packers until the desired level is reached. The second stage entails using packers on the sides; to prevent tilting forwards or backwards, so the double glazed window does not fall out when it is no longer manually supported.

If the double glazed window leans forwards or backwards, the window was not levelled correctly. This can result in window sash swinging in or out (if casement) when it would otherwise have stayed in position without having to apply the lock. It is prudent to check everything before moving onto the next stage.

The second stage involves screwing the window in place. We recommend using 120mm size screws. Decide on the corner for the first bottom screwing points - either left or right.

The screws are affixed one side a time, and it is necessary to maintain the window level during this process. The screwing points are strategically selected: the primary screwing points are 100mm from the bottom and top, and the remaining screwing points 350-400mm in between the top and bottom points. The number of screwing points depends on the window and door size.

On first application, the screws are tightened lightly, and only finished tight after all the screwing points have been attached. Failure to leave the screws gently fixed may result in the window curving slightly on one side. If the side looks bent, it is possible to decrease the magnitude by releasing the screw somewhat, adding packers then re-tightening the screw.

Sealing Secondary Double Glazed Windows and Doors for Insulation

It requires considerable skill to seal the new secondary double glazed window on the outside because movement is restricted by existence of the original window, so a corner nozzle for sealant is used to reach far enough to seal the window completely. If it is not possible to get access between the new and existing windows with a sealant, it will result in incomplete weather sealing, which will compromise the technical excellence and high performance of the new double glazed windows or doors. The use of corner nozzle will eliminate the need for squeezing and reaching between narrow space, save time and provide a more through seal around the window.

The aperture and the window require cleaning with a wet cloth at this point, because expandable foam and silicon are applied next. If the area is dirty, the silicon will not adhere properly and dust will become trapped on the surface, resulting in a sloppy and messy appearance. Dust is normal, and appears during drilling, but it has to be removed to enable good adhesion of filling substances and, therefore, insulation for the window.

Expandable foam is applied before the silicon on all gaps bigger than 7mm wide, and is left to dry for an hour. Once the protruding excess of the foam is trimmed down with a knife, silicon can be applied.

To ensure that the window looks attractive and stylish when the installation is complete, the right colour of silicon should be selected. Ideally, the silicon colour should match the window colour. The silicon that is used on the outside should be waterproof to prevent water leakage. Although using a waterproof silicon on the inside is desirable, sometimes the owner's priority is for interior design, so to allow the possibility of different finishes, using silicon that can be painted may be more practical to such clients.

The silicon is not only cosmetic, but also provides an effective waterproof, weatherproof and noise proof barrier for maximum insulation rating of the double glazed panel, window or door. Silicon dries quickly, but care should be taken nevertheless not to smear it.

Glazing of Secondary Double Glazed Windows and Doors

Care must be taken and safety remembered at all times, since the double glazed units can be particularly heavy and the risk of injury higher than working with window frames.

Glazing also requires use of additional tools comprised of:

• Glass suction cups/ vacuum cups
• Rubber or plastic hammer
• Glass/ Glazing packers
• Silicon or plastic glue

To start, apply glass/glazing packers on the bottom section of the frame/sash, on top of the indentation for glazing in the profile. The width of the packers should be between 5-7mm. This will raise the insulated glass unit, and even if you install the window correctly, it is still necessary to keep the glass straight and centre it inside the window. The double glazed unit differs from a single pane of glass in that if the double glazed unit is not centred, it will be obvious and it will compromise the modern and stylish design of the window.

The glass should be centred, that is, the distance of the gap at the top is the same as at the bottom. The side packers will keep the glass straight and prevent movement inside the sash. From the top, measure about 1/3 of the height of the glass pane, and by using plastic glue or silicon, attach glass packers to the side of the glazing indentation in the profile. For best results, the suction cups should be used for the next step. Place the glass in the prepared area. By using vacuum cups, it is possible to move the insulated glass unit around inside the glazing area, to make slight adjustments in order to achieve the desired position. Finally, using a rubber or plastic hammer, tap the glazing bead or strips around to hold the glass in place.

Final Step of installation of Double Glazed Windows and Doors

Where appropriate, (not on fixed panels) fit the handle and hinge covers. Test the window by opening and closing to ensure it is operational.

You should not have to use force to open and close the window, and it should be airtight when closed. The sash should fit into the frame and there should be no gaps between frame and sash and frame and wall when closed. If the window or door looks crooked it has not been correctly installed. Open the sash a few times and check if the operation is smooth and comfortable. It is possible to ease or tighten the operation according to he users preference.

Many people have the impression that all silicone gels on the market are the same, but we have found that their properties and, therefore, suitability varies dramatically. Generally, the descriptions of silicone offer little information as to the correct grade and type for a given application, and because of performance variability, there is no one type of silicone sealant that should be used for everything. Using the incorrect silicone or improper use may cause joint failure, contamination of surfaces because of poor application, excessive movement in the sealed joint.   Read more on double glazed sealing

Upvc is the ideal frame material due to its inherent qualities of resistance to corrosion, fire, water, and sunlight. Apart from the most obvious applications in coastal areas where salt destroys the appearance and function of aluminium windows, while wooden windows must be specially treated with chemicals or paint, upvc frames have also been used in commercial and industrial applications and in areas of high pollution or for high impact winds.
