Disadvantages of SIP panels
- SIPs have the same transportation limitations as panelized elements.
- Cranes are often used for installation, requiring careful project site planning for material delivery.
- Special tools might be needed for on-site modifications.
- A special concern is OSB’s sensitivity to moisture, which must be carefully managed on-site to reduce SIP damage.
- Panel damage or on-site changes can require the entire panel to be replaced, which increases the cost and duration of construction.
- SIPs must not be placed in direct contact with the ground and should be organized in an efficient process that allows the worker to easily read identification marks or labels for each panel.
- SIPs require exterior finishes that protect the structure from water. Asphalt shingles are recommended for a SIP roof. Steel, tile, vinyl, wood, or brick are suitable for siding.
- The insulated foam provides an excellent nesting material for pests. Periodic inspections must be carried out.
- Because SIP panels are practically hermetically sealed and do not allow air exchange, a good ventilation system must be provided for the building to ensure the health and safety of the occupants. Passive air infiltration will not be adequate for good indoor air quality.
- It is recommended that indoor humidity should be controlled by the ventilation system.
