uPVC windows are a preferred choice in Saudi Arabia for heat and sound insulation, but they occasionally face some issues, such as leaks, difficulty in opening and closing, and external noise.<\/span><\/p>\n

At<\/span> Home View Saudi Arabia<\/span><\/a>, we are keen to provide our customers with practical solutions to these problems in a simplified manner. This article reviews the most <\/span>common uPVC window problems,<\/i><\/b> and the available solutions to maintain comfort and ideal insulation in your home.<\/span><\/p>\n

\u00a0<\/span><\/p>\n

First – The Problem of Leaking Windows: Causes and Remedies<\/span><\/h2>\n

Often, <\/span>water or air leakage<\/b> occurs due to a defect in the insulation around the window frame or blocked drainage channels (weep holes).<\/span><\/p>\n

During window installation, gaps in insulation may appear, or damage to the <\/span>rubber gaskets<\/b> can occur; therefore, it is recommended to check the seals around the window regularly and replace damaged gaskets.<\/span><\/p>\n

Additionally, <\/span> blocked drainage holes<\/span><\/a> lead to rainwater pooling inside the frame, and subsequently leaking inside.<\/span><\/p>\n

\u00a0<\/span><\/p>\n

Solutions for Window Leakage Problems<\/span><\/h3>\n

1 – Cleaning Drainage Channels (Weep Holes)<\/span><\/i><\/h4>\n

Use a soft brush or water from a hose with slightly strong pressure to remove dirt from the drainage holes, so that water flows outwards without accumulating inside the frame.<\/span><\/p>\n

\u00a0<\/span><\/p>\n

2 – Resealing the Frame<\/span><\/i><\/h4>\n

If the insulation was applied using silicone or insulating foam, new sealant silicone must be applied around the window edges after cleaning the old one. Use a high-quality special silicone like Dow Corning to fill any cracks.<\/span><\/p>\n

\u00a0<\/span><\/p>\n

3 – Checking the Filter Slope (Virtual Window Ceiling)<\/span><\/i><\/h4>\n

Ensure the window is slightly tilted outwards so that water does not pool. Incorrect installation with a downward tilt can cause water to stay at the edges.<\/span><\/p>\n

\u00a0<\/span><\/p>\n

4 – Ensuring the Frame is Secured<\/span><\/i><\/h4>\n

If the frame is loose, it must be firmly fixed with screws, and gaps around it should be filled with polyurethane foam (expanding foam) and then re-covered with silicone.<\/span><\/p>\n

\u00a0<\/span><\/p>\n

Bottom Line<\/span><\/h5>\n

Leakage<\/b> is often due to seal failure or blocked drainage. Solutions begin with inspecting and cleaning the frame gaskets and resealing any gaps.<\/span><\/p>\n
