Typhoon "Huajiasha" swept through coastal areas with a wind force of 14, causing deformation of door and window frames, glass breakage, and detachment of sealing strips in many areas.

The hardware components of high-rise residential windows have become loose due to excessive wind pressure, balcony sliding windows have accumulated water due to blocked drainage holes, and the aging and cracking of sealant in old residential areas have led to rainwater leakage... These scenes expose the fragility of the door and window sealing system.

How to systematically solve the sealing hazards of doors and windows after typhoons? Genesis provides solutions with professional performance.

PART-01

After the typhoon, three major pain points in door and window sealing have been exposed

1. During the typhoon, the pressure on the windward side of high-rise buildings with more than 20 floors exceeded 300 Pa, and poor quality sealing strips suffered permanent deformation due to insufficient elasticity, resulting in a 0.5-2mm gap between the window frame and the glass.

2. Failure of structural adhesive bonding. Traditional acidic glass adhesive has poor weather resistance and may peel off at the bonding interface under strong wind pressure during typhoons (with a single point force of 200 kilograms on window frames during a level 12 typhoon). Statistics show that 28% of door and window failures after typhoons are caused by structural adhesive cracking between glass and window frames, leading to glass shaking or even detachment.

3. The drainage system is blocked, and the sliding window track drainage hole is blocked by debris, resulting in water accumulation exceeding the sealing line of the window frame. Tests have shown that during typhoons, sliding windows with poor drainage can accumulate up to 3cm of water within 2 hours, causing the wall below the window sill to become wet.

C-678 | Technological Breakthrough Designed for Extreme Weather

1. The military grade weather resistance performance adopts imported silicone modified polymer, which has been tested according to GB 18583-2008 standard. It maintains elasticity under a temperature difference of -40 ℃ to 150 ℃ and has a tensile strength of 1.8MPa.

2. Elastic adaptation window frame "elastic buffer layer+rigid adhesive layer", can adapt to window frame deformation of 0.5-3mm.

3. Environmental protection and safety are both guaranteed through SGS environmental certification. The VOC content is less than 10g/L, and it is non-toxic and odorless after curing. Colloidal hardness is high, ensuring both impact resistance and avoiding stress concentration in glass caused by hardness.

Sealing System Reconstruction | Four Step Method for Door and Window Repair

1. Comprehensive testing

• Appearance inspection: Use a strong flashlight to illuminate the glass and observe hidden cracks; The verticality of the window frame should be checked with a level, and if the deviation is greater than 2mm, it needs to be replaced as a whole.      

•Sealing test: Insert A4 paper into the window gap, and the pulling resistance should be greater than 5N; use a smoke pen to detect air leakage points and record the location of the leakage.      

•Hardware evaluation: Check the locking force of the handle (should be greater than 30N), the resistance to hinge rotation (should be less than 1.5N · m), and replace rusted parts.

2. Reconstruction of sealing system

•Rubber strip replacement: EPDM material rubber strip should be selected, and the cross-sectional design should match the window type (D-type for casement windows and P-type for sliding windows). Reserve 5% compression during installation to ensure even sealing pressure.

• Sealing glue construction:

▶  Substrate treatment: Polish the oxide layer with an angle grinder, clean with alcohol, and apply primer.      

▶  Glue application process: Use an electric glue gun to move at a constant speed at a 45 ° angle, with a glue seam width controlled between 8-12mm and a depth of half the width.      

▶  Timing of trimming: After the surface dries (about 30 minutes), use a scraper to trim it to avoid difficulty in adjusting after curing.

3. Optimization of drainage system

•Drainage hole dredging: Clean the track drainage hole with a φ 5mm needle and install mosquito nets to prevent secondary blockage.      

•Waterproof threshold reinforcement: Pour C20 concrete threshold below the balcony door, with a height of 10cm, and paste 2mm thick waterproof adhesive strip on the inside.

4. Emergency protection enhancement

•Glass reinforcement: For cracked glass that has not yet ruptured, use 5cm wide tape to stick a "m" shaped reinforcement to delay the rupture time.      

•Anti fall device: Install limiters on high-rise exterior windows to control the opening angle to ≤ 30 ° and prevent strong winds from lifting the windows.

Construction quality determines service life | Professional construction advice

1. Material selection

•Sealing glue: Genesis C-678, suitable for sealing various types of building doors and windows, suitable for door and window production and use.

2. Construction specifications

•Environmental requirements: Construction temperature should be between 5-40 ℃, humidity should be less than 85%, and outdoor work is prohibited on rainy days.      

• Safety measures: When working at heights, it is necessary to wear a five point safety belt and use an electric lifting platform.

3. Acceptance criteria

• Sealing: Airtight box testing, when the pressure difference is 100Pa, the leakage rate per unit area is less than 1.5m ³/(m ² · h).      

•Appearance quality: The surface of the adhesive joint is smooth, without bubbles or cracks, and transitions naturally with the substrate.
