This low - maintenance characteristic makes aluminum windows a convenient choice for busy homeowners and building managers.

 Installation Process of Aluminum Around Windows

 Pre - installation Preparation

Before installing aluminum around windows, thorough preparation is essential. First, the existing window and its surrounding area need to be carefully inspected. If replacing an old window, the old window frame, glass, and any associated trim must be removed. This process should be carried out carefully to avoid damaging the surrounding wall structure.

The opening for the new aluminum window should be measured accurately. The width, height, and depth of the opening need to be determined to ensure a proper fit for the new window unit. Any irregularities in the opening, such as uneven walls or damaged framing, should be corrected before installation. Additionally, the necessary tools and materials, including the aluminum window unit, screws, sealants, and insulation, should be gathered and prepared.

 Frame Installation

Once the preparation is complete, the aluminum window frame can be installed. The frame is typically placed in the window opening, and its position is adjusted to ensure it is level and plumb. Shims may be used to fill any gaps between the frame and the opening and to achieve the correct alignment.

The frame is then secured to the wall using screws or anchors. In the case of wooden walls, screws can be directly inserted into the wall studs. For masonry or concrete walls, anchors are required to provide a secure attachment. After the frame is firmly in place, the gaps between the frame and the wall are filled with insulation material, such as foam insulation, to improve energy efficiency and prevent air leakage.

 Glass and Hardware Installation

After the frame is installed, the glass panes are inserted into the frame. The type of glass used depends on the specific requirements of the window, such as energy efficiency and sound insulation. Once the glass is in place, it is secured with glazing beads or other securing mechanisms.

The hardware, including hinges, locks, handles, and any automated opening systems, is then installed. The hinges are attached to the frame and the window sash, ensuring smooth operation. Locks and handles are installed for security and ease of use. If an automated system is being installed, such as a motorized opening mechanism for large windows, it is carefully integrated into the window system and tested for proper functionality.

 Trim and Finishing

Finally, the aluminum window trim is installed. Exterior trim, such as sill pans, head flashing, and jamb extensions, is attached to the frame to provide a weather - tight seal and enhance the appearance. Interior trim is installed to cover the gaps between the frame and the wall and to create a finished look.

Sealants are applied around the edges of the trim and the frame to ensure a watertight and airtight seal. This helps to prevent water infiltration and air leakage, improving the energy efficiency and performance of the window. The entire window installation is then inspected to ensure that all components are properly installed and functioning correctly.
