What They Do

IPB Insulated Headers eliminate thermal bridging.

Thermal bridging takes place when a continuous section of wood is connected (bridged) from outside a building to inside the building.

Also called a cold bridge or heat bridge, it is an area of a building which has a significantly higher heat transfer than the surrounding materials resulting in an overall reduction in thermal insulation of the building, increasing energy expenses and creating a less cozy building interior.

Thermal bridging occurs when a section of wood, such as a lumber header runs from the inside to the outside of a building. Wood, even though it has some insulation properties is still a conductor and when its cold outside a solid wood header will transfer heat to the outside robbing the building of its energy.

Thermal bridging in buildings not only reduces energy efficiency it can allow condensation (moisture) and thermal comfort problems. Condensation can result in indoor air quality problems and deterioration of the building.

IPB Insulated Header’s core of EPS insulation is laminated to both inner sides of the header lumber eliminating the cold bridge. This simple, inexpensive building solution performs the same for strength but makes a huge difference in energy performance and building operating costs!

How They Are Made

Wood /EPS headers use two lumber elements with a core of expanded polystyrene insulation pressure laminated to the lumber with capacity to bear a load.

Panel headers are essentially a small section of insulated panel filling a space with minimal or no requirement for load bearing capacity.

Insulated Panel Headers and lumber / EPS headers increase the energy use performance of a building by eliminating thermal bridging. Both of these products the Expanded Polystyrene rigid foam breaks the bridge and stops all conductivity.

Our headers are constructed by laminating structural lumber to a core of EPS foam insulation.
