Buying Guide
What to check before buying:
- Length needed: Measure the door width and buy a seal that matches or exceeds it to avoid gaps.
- Material: EPDM rubber lasts longer in harsh climates; standard rubber works for milder conditions.
- Profile design: U-shaped channels with end plugs offer stronger end seals; T-end designs provide robust edge sealing.
- Temperature range: For extreme cold or heat, choose materials rated well below/above typical seasonal temps.
- Adhesion and installation: Some kits use adhesive while others are screw-free; pick based on your skill level and door type.
- Visibility and fit: Colored strips or serrated bases can aid alignment and safety during installation.
Installation considerations
Prepare the door edge and threshold by cleaning dust and debris. Trim seals to fit using a utility knife. For end plugs, install according to the channel design to ensure a snug seal. Check the entire length after installation and reseal any gaps.
Maintenance tips
Clean seals regularly with mild soap and water to extend life. Inspect for cracks, hardening, or detachment at the ends, and replace sections as needed to maintain airtight performance.
