I have heard in the past that houses should breathe and have attic ventilation. Wouldn spray-foam insulation seal my house too tight?
Your house DOES need to be ventilated, BUT most home engineers and building scientists (as well as the US Department of Energy) advise that you seal the structure as tight as possible and provide necessary ventilation through your air conditioning and heating system. Many systems employ an “air exchanger” which pre-conditions incoming outside air to control humidity and energy efficiency. This type of design along with spray-foam creates a true Thermal Envelope.
