Each time a storm accompanied by heavy rain hits, it poses a formidable challenge to the integrity of aluminum window profiles and doors. People are particularly concerned about their air-tightness, water-resistance, and stability during such weather conditions. In the rainy season, numerous households report instances of leaks in aluminum window frame extrusions and doors, leading to mildew on floors and walls seemingly without cause.

So, why do these leaks occur?

While many might attribute the issue solely to product quality, leaks can stem from various factors:

1.Inadequate Installation:

Insufficiently trained assembly workers may overlook crucial steps during installation.

Proper sealing using high-elasticity rubber strips between metal frames and window frames is vital for water-proofing.

Ensuring a slight angle on window lintels and sills facilitates water drainage.

Regular testing post-installation is imperative to catch any potential issues early on.

2.Window Instability:

Loose connections between window sashes and aluminum window frame sections are a common issue.

Continuous usage and wear can exacerbate vibrations, widening gaps between frames and walls.

Poor-quality products with insufficient hardness may deform over time, leading to surface issues like color fading or flaking.

⭐ Solutions:

Regularly checking and maintaining the gaps between walls and aluminum window frame sections.

Replacing aging or damaged sealing materials and applying sealant to the gaps.

Using padding to fill wider gaps before sealing.

3.Damage to Water-Proof Layers:

Older houses may suffer from deteriorated water-proof layers around the windows due to aging.

Neglecting to repair damaged water-proof layers during renovations can also lead to leaks.

⭐ Solutions:

Repairing damaged water-proof layers by accessing them through the exterior walls.

4.Blocked Draining Holes:

Certain aluminum windows, particularly sliding ones, may lack draining holes, causing water to accumulate in the tracks.

Construction debris or other obstructions can inadvertently block draining holes, leading to water seepage.

⭐ Solutions:

Thoroughly cleaning the tracks and draining holes to ensure unimpeded water flow.

If draining holes are improperly positioned, creating new ones using hole punches is recommended.

By identifying these common issues and implementing the suggested solutions, homeowners can mitigate the risk of leaks and preserve the integrity of their aluminum windows and doors, even during adverse weather conditions.
