2. Can folding window doors be set up in existing homes, or are they just for new building and construction?
They can certainly be installed in existing homes through a retrofit process. Nevertheless, doing so may require structural modifications, such as installing a steel header or lintel to support the weight of the wall once the opening is widened.
3. Do folding windows leakage water during heavy rain?
Modern, expertly set up folding window systems are engineered with advanced weather-rated sills and drain channels. When installed properly, they effectively avoid water infiltration even during severe storms.
