Tempo:
Sensitivity to workmanship—As is the case with many multi-component, hand-applied systems, EIFS performance is sensitive to workmanship. Quality control is necessary to assure the various components are properly applied and that they effectively work together to provide the desired performance.
Long-term performance—While a minimum 30-year service life for properly designed and applied EIFS is anticipated and indicated by field performance, longer term service for many product formulations has not been determined. As with all cladding, maintenance is a prerequisite to longevity. Problems with local deterioration or moisture ingress must be dealt with promptly to achieve an acceptable service life.
SUSTAINABLE HOUSING INSIGHT Healthy Indoor Environment
Water entering the house can cause mold growth. As the cladding on a house is the first line of defence against water infiltration, it should be designed and installed to resist water penetration. It should also be maintained in good repair to keep water out of the wall system.
Resource Efficiency and Affordability
Energy Efficiency
Consider using high levels of rigid insulation over the exterior wall framing to reduce thermal bridging and increase the thermal insulation in the building envelope.
Exterior Insulation Finish Systems provide both insulation value and a finished wall surface, and can effectively reduce thermal bridging caused by the wall framing.
Carefully estimate the amount of cladding material required including some allowance for wastage, rejection and future repair. When ordering materials, investigate the possibility of returning unused materials for a partial or full refund. Store and handle materials to avoid damage. Reduce cladding and sheathing waste by applying the 4 Rs: reviewing, reducing, reusing and recycling materials.
