Building system and method utilizing integrated insulation, method to construct wall panel

A method of constructing a wall panel comprising the steps of:

• a. providing a rigid framing;
• b. elevating the rigid framing above a non-stick surface such that a predetermined amount of space is formed between the rigid framing and the non-stick surface;
• c. applying a single layer of foam insulation, the single layer of foam insulation:
• i. fills the predetermined amount of space between the rigid framing and the non-stick surface;
• ii. fills an interior section rigid framing;
• iii. encapsulates an exterior flange of the rigid framing;
• d. leaving a utility cavity between an interior face of the single layer of foam insulation and an interior surface of the rigid framing;
• and
• e. allowing the single layer of foam insulation to dry wherein a solid monolithic piece is formed comprising the single layer of foam insulation fused to the rigid framing.
