Installing Double Glazed Windows for Renovations and Refurbishments

When it comes to replacing double glazed windows and double glazed doors, two primary installation methods exist, both requiring thorough preparation.

Tools Required:

• Gloves, Goggles

• Tape Measure, Spirit Level, Pencil

• Electric Screwdriver

• Hand Drill with 3, 3.5, or 4mm Drill Bits

• Screws (various sizes)

• Any type of Saw (for cutting aluminum angles)

• Expanding Foam

• Window Packers (1, 3, 7, 12mm)

Initial Preparation:

Replacing windows and doors can be a messy task, so it’s crucial to minimize debris and damage to surrounding areas. Begin by clearing the vicinity of the window, removing any blinds and curtains, and covering floors with rugs. Remove any valuable items from the area to prevent damage.

Removal of Existing Windows and Doors:

Start by taking out the old window glass and frame. For small aluminum windows, you might remove the sash with the glass intact. Generally, the glass is removed first, followed by the sashes and frames. The removal process depends on the type and size of the window or door and its frame material. Cleaning the aperture is essential after removal. Fill the cavity between bricks with aluminum or hardwood for a secure base. This step ensures the new window can be properly screwed in place.

Fitting New Double Glazed Windows and Doors:

Insert the double glazed window into the aperture in two stages. First, level the window horizontally using packers until the desired level is achieved. Next, use packers on the sides to prevent tilting. Trained installers recommend using 120mm screws. Start by screwing in the bottom corners, 100mm from the top and bottom, with remaining screws 350-400mm apart. Lightly tighten the screws initially, then fully tighten after all are in place to avoid bending the frame.

Sealing for Insulation:

Clean the aperture and window with a wet cloth before applying expandable foam and silicon. This ensures proper adhesion and a neat appearance. Apply expandable foam to gaps larger than 7mm, let it dry, then trim the excess. Choose silicon that matches the window color for a stylish finish. The silicon provides a waterproof, weatherproof, and noise-proof barrier, enhancing the insulation of your energy efficient windows.

Glazing:

Handle double glazed units with care, as they are heavy and pose a higher risk of injury. Use glass suction cups, a rubber or plastic hammer, glass packers, and silicon or plastic glue. Place packers on the bottom section of the frame to keep the glass straight and centered. Attach side packers with silicon or glue to maintain the position. Use suction cups to adjust the glass as needed, then secure it with glazing beads or strips.

Final Steps:

Fit handles and hinge covers where appropriate. Test the operation of the double glazed window or door to ensure it opens and closes smoothly. It should be airtight when closed, with no gaps between the frame and sash or frame and wall. Adjust the operation as needed for smooth and comfortable use.

By following these steps, you ensure a proper installation of double glazed windows and doors, enhancing the energy efficiency of your home. Remember, quality upvc double glazed windows and doors, manufactured in Sydney, can significantly improve your home’s insulation and energy efficiency.
