Yes, windows can indeed be installed from the inside of a building.
Based on information regarding window replacement practices, installation is possible using either an interior or exterior approach. According to a reference from 09-Mar-2023, "Windows can be installed both from the inside and the outside."
While it is technically possible to install windows from the inside, professional installers most "commonly... fit your windows from the outside."
Installation Methods
The choice between installing windows from the inside or outside often depends on various factors:
- Outside Installation (Common): This is the standard method for many types of windows. Installers work from scaffolding or ladders outside the building. It often allows for easier flashing and sealing from the exterior weather barrier perspective.
- Inside Installation: This method is often preferred or required in specific situations:
- High-Rise Buildings: Exterior access can be difficult or dangerous. Installing from the inside is often the only practical option.
- Difficult Exterior Access: If landscaping, obstructions, or the structure of the building makes working from the outside challenging.
- Weather Conditions: In instances of severe cold, heavy rain, or strong winds, working from the inside can be safer and more comfortable for the installers.
Regardless of whether the installation is performed from the inside or outside, proper sealing, insulation, and structural fastening are crucial for the window's performance and longevity. The method primarily affects the workflow and accessibility rather than the fundamental function of the installed window unit itself.
Summary of Installation Possibilities:
- Inside Installation: Possible, often used when outside access is limited.
- Outside Installation: Possible, the common method used by professionals.
Choosing the right method depends on the specific project requirements, site conditions, and installer expertise.
