The electromagnetic field (EMF) is an entity that encompasses the magnetic field and the electric field. Electromagnetic fields are produced wherever electrical currents exist. Thus, every time we use household appliances, we expose ourselves to electric and magnetic fields. The intensity of the electromagnetic field is directly proportional to the intensity of the current and decreases exponentially with the distance from the source. The intensity is expressed in milligauss (mG) in North America and in Tesla (T) or micro tesla (μT) in Europe. The electromagnetic field is like an invisible cloud that radiates around any connected electrical device that is in operation.

Since the polystyrene beads are bonded to each other, this material is more permeable to moisture than an extruded polystyrene insulation.

Instrument for measuring the resistance of a component or an electrical circuit. The units of measurement is Ohm, KOhm or MOhm.

Structural wood panel manufactured by gluing under pressure and at high temperature thin strips of wood in specific orientations.

A type of strong thin wooden board consisting of 2 or more layers glued and presses together with the direction of the grain alternating.

Transfer of heat from a hot surface to a cooler surface or object by infrared waves.

A heating system designed to directly transfer radiant energy from a heat source to objects or occupants of the heated space. In homes, radiant heating systems most often have electric cables or hot water pipes arranged in loops inside ceilings, walls or floors.
