Proper Housewrap and Weather Barriers
Before installing siding, a high-quality weather-resistant barrier (WRB) like Tyvek or Typar should be applied over the sheathing. This prevents air and moisture infiltration while allowing vapor to escape.
- Use breathable housewrap in humid climates
- Ensure all seams are taped and sealed
- Install kick-out flashing at roof-to-wall junctions
Flashing and Water Management
Flashing is critical around windows, doors, and roof intersections. Improper flashing is the leading cause of water damage in siding systems.

- Install Z-flashing above windows and under sills
- Use pan flashing for sliding doors
The Building Science Corporation emphasizes that “water management is more important than insulation in wall design.”
Nailing and Expansion Gaps
Insulated siding must be nailed correctly to allow for thermal expansion and contraction.
- Nail at the center of the nailing hem
- Leave a 1/32” gap between panels
- Do not overdrive nails—they should be flush, not tight
Vinyl siding, in particular, expands significantly in heat and contracts in cold. Improper nailing can lead to buckling or warping.
Maintenance Tips to Extend the Life of Your Insulated Siding
Regular maintenance ensures your durable insulated siding options perform optimally for decades.
Annual Cleaning and Inspection
Wash siding annually with a mild detergent and garden hose. For tougher grime, use a soft-bristle brush or low-pressure washer (under 1,500 PSI).
