While the benefits of using capillary tubes are straightforward, there are numerous issues when considering their use including:
- Magnitude of elevation change to require use
- IGU pressurization due to temperature difference
- Use with insulating gases
- IGU sizes and aspect ratios
- Glass thickness, type and coatings
- Glazing space thickness
- Short term (in transit) vs. long term (installed) elevation and/or temperature changes
- Types of edge seal construction
- Multiple-cavity IGUs (triples, quads, etc.)
- Proper IGU design and fabrication for use of capillary tubes
