Integrating Insulation and Surface Finishes into Concrete Walls and Floors

摘要

Available concrete systems integrate insulation and concrete into one system.These systems have the benefit of providing thermal mass and continuous insulation to reduce energy loads.This combination reduces thermal bridging often found in steel or wood frame construction and provides continuous air and thermal barriers.Examples include insulating concrete form (ICF) systems and insulated precast sandwich panel walls.Decorative finishes,when used in precast systems,are integral to the interior or exterior surface of concrete walls and the top surface of concrete slabs.Exterior decorative finishes eliminate the need for siding materials while providing a hard,durable exterior surface.Interior decorative finishes eliminate the need for gypsum wallboard and also provide a durable interior surface.Formed and colored or stained surfaces can closely match cut stone or other historic facades,and can mimic brick veneer.Decorative finishes on floors eliminate the need or additional flooring finishes such as carpet or wood.Geometric patterns can be scored,stamped,rolled or inlaid into the concrete.The top surface can be ground to expose aggregate for an effect similar to terrazo.These concrete systems are a resource efficient method of providing thermal mass and low air infiltration.In addition,concrete has low volotile organic compounds (VOC) emissions and does not degrade indoor air quality.
