Installation Methodologies and Best Practices

Comprehensive Installation Guide

Proper installation is critical for achieving rated performance. RUBASIA provides detailed technical support for all installation scenarios.

Preparation Phase

1 Door Inspection:

◦ Verify door alignment and track condition

◦ Check for damage or misalignment affecting sealing surface

◦ Measure gap dimensions at multiple points along door width

◦ Document floor irregularities for threshold seal coordination

2 Surface Preparation:

◦ Clean groove or mounting surface thoroughly

◦ Remove old seal material and adhesive residue

◦ Degrease with isopropyl alcohol or approved cleaner

◦ Ensure surface temperature between +10°C and +40°C for adhesive applications

3 Material Selection Verification:

◦ Confirm profile matches door groove dimensions

◦ Verify material type matches environmental requirements

◦ Check length requirements (door width + 5% allowance)

Installation Procedures by Profile Type

Method A: T-Bar Seal Installation (Sliding Fit)

1 Lubrication: Apply silicone-based lubricant to groove and seal head

2 Insertion: Starting from one end, feed seal into groove maintaining consistent pressure

3 Progression: Work along full length, avoiding stretching or compression

4 Trimming: Cut excess length with sharp utility knife, allowing 2-3mm compression at ends

5 End Caps: Install compatible end caps to prevent seal migration over time

6 Verification: Cycle door 3-5 times to verify smooth operation and full floor contact

Method B: Wrap-Around Seal Installation

1 Positioning: Raise door to comfortable working height, exposing bottom rail

2 Alignment: Position seal centrally on T-bar section

3 Clipping: Starting from one end, press and clip one side of wrap-around flap onto the T-bar

4 Progression: Work along full length, maintaining consistent tension

5 Second Person Assistance: Recommended for doors exceeding 3 meters width

6 Verification: Ensure seal is square and fully engaged along entire length

Method C: Brush Seal Installation

1 Position Selection: Identify optimal position on bottom inside edge

2 Pre-drilling: If required, pre-drill holes in aluminum carrier

3 Temporary Fixing: Secure carrier with clamps or tape

4 Marking: Mark screw hole positions with pencil

5 Fastening: Install self-tapping screws with appropriate driver

6 Trimming: Trim ends flush with door edges after installation

7 Verification: Check door closure and adjust if necessary

Floor Threshold Seal Integration

For sites with uneven floors—common in older buildings across towns like Tawau, Sibu, and Kuching—our door seals are designed to work in conjunction with aluminum or rubber floor threshold seals, creating a complete "4-sided seal" solution. This integration is critical for:

• Flood prevention in low-lying areas

• Pest exclusion in food facilities

• Energy efficiency in climate-controlled spaces
