Window Opening in Interior Walls of Prefabricated Panel Houses

Whether it is possible to open windows in the interior walls of prefabricated panel houses requires discussion on a case-by-case basis and cannot be generalized.

For prefabricated panel walls in brick-concrete structures, windows cannot be opened under any circumstances. In brick-concrete structures, prefabricated panel walls usually serve as load-bearing walls, bearing part of the weight of the house and being key structural components that maintain the overall stability of the building. Opening windows would damage the integrity and load-bearing capacity of the wall, leading to uneven stress distribution in the wall and affecting the stability of the house. Especially during natural disasters such as earthquakes, this kind of damage would make the wall more prone to collapse or fracture, seriously threatening the lives of the occupants. In addition, according to Article 5 of the 'Measures for the Administration of Interior Decoration and Renovation of Residential Buildings', it is prohibited to enlarge the original door and window sizes on load-bearing walls. Enlarging window sizes is an illegal act and will face corresponding penalties. Therefore, opening windows in the prefabricated panel walls of brick-concrete structures is absolutely not advisable.

For non-load-bearing walls in prefabricated panel structures composed of prefabricated assembled concrete lightweight insulation panels, square steel keels, reinforced concrete components, etc., theoretically, they can be removed, but caution is still required when opening windows. These walls do not bear the main weight of the house and can theoretically be removed or renovated. However, before removal or renovation, a static load test must be carried out to determine the load-bearing capacity of the wall, and safety measures such as reinforcing the wall and covering it with protective nets should be taken to prevent damage to the surrounding environment and personnel safety. If windows are to be opened in such walls, it is also necessary to carefully evaluate their structural impact to ensure that opening windows will not damage the integrity and stability of the wall. In addition, according to relevant regulations, construction cannot be carried out without the assessment and approval of a professional design unit. This is to ensure the structural safety of the renovated house and avoid safety accidents caused by improper renovation.
