If there are gaps between the window frame and the wall, first clean the缝隙 thoroughly, then fill it with expanding foam. After that, use high-grade cement mixed with river sand to seal the gap completely, followed by finishing touch-ups for a smooth appearance. For leaks between the window sash and the frame, consider adding sealing strips or weatherstripping. And if the gaps are particularly large, installing an additional PVC or plastic steel window inside the existing one would be a better solution.
1. Trick #1: Classic Window Layout with Mezzanine Floor
For double-layered, older-style windows, the best solution is to fill the gap between the panes with sawdust. Not only does sawdust help address moisture issues in the window area, but it also effectively blocks the strongest cold air from seeping in at the bottom of the window. As for gaps around these types of windows, you can seal them tightly using kraft paper and paste, ensuring an airtight barrier that keeps the temperature surprisingly high.
2nd Trick: Adding a Layer of Plastic to PVC Windows
Over time, PVC windows tend to become drafty, with gaps at the joints that are too large to seal effectively. The best solution is to first apply a layer of sponge around the window frame, then cover the entire window with a plastic enclosure. This plastic not only absorbs heat efficiently but also creates an airtight barrier, helping to maintain a stable and comfortable temperature inside.
3. Trick #3: Dealing with Window Gaps
If there are gaps between the window frame and the wall, first clean the缝隙 thoroughly, then fill it with expanding foam. After that, use high-grade cement mixed with river sand to seal the gap completely, followed by finishing touch-ups for a smooth appearance. For leaks between the window sash and the frame, consider adding sealing strips or weatherstripping. And if the gaps are particularly large, installing an additional PVC or plastic steel window inside the existing one would be a better solution.
4. Trick Four: Using Styrofoam to Address Remaining Installation Issues
First, determine whether the issue stems from improper installation by the workers or if it’s a problem with the product itself. If the fault lies with the product, you should contact the dealer or the manufacturer. On the other hand, if the problem was caused by minor mistakes during installation by the workers, you can simply remove the item and reinstall it properly. Alternatively, you can start by thoroughly cleaning the gaps between the window frame/door casing and the wall, then fill them tightly with expanding foam. After that, use a mixture of cement and sand to carefully seal the gaps, and finally apply touch-up work to ensure a smooth finish.
Different windows require different solutions to fix drafts—of course, choosing the right window is key!
