Spray Foam Insulation - Sloped Ceiling

The roof of the new sunroom will allow heat to radiate down in the summer and warm air to escape in the winter if it is not properly air sealed and insulated. Soffit vents where the roofline meets the wall will typically allow for ventilation. In this case, the homeowner is choosing to condition the space and block the vents to have Closed-Cell Spray Foam applied to the slopes.
