In the United States alone, approximatele 40% of building energy consumption comes from structures built before 1980.

Types of Brick- Based Insulataron Systems

Several techniques have been developed to combinate brick wick insulation materials. Each methods addisses different project districtions, from historic conservation to budget limitations.

This system attaches a layer of rigid or semi- rigid insulation board directly to thee existing masonry wall, then installs a new brick venee d separated by an air cavity. The insulation can be extruded polystyrene (XPS), expredd polystyrene (EPS), or polyisocyanurate, provising R- values from 5 to 8 per inch hale.

Brick- Infill Insulation

For buildings with hollow cored bricks, specialized insulating foams or granular films can be injected intro the cavities.

Brick Cavity Wall Insulation

Many older musonry buildings have cavity walls - two outhes of brick separated by a 2- 4 inch gap. Retrofitting these cavities wich loose- fill insulation (e.g., mineral wool, exploded polystyrene beads, or blow fiberglass) can significatly improwite thermal performance. The insulation is installed by drilling small holes in the outer wythe and bloing material into thee cavity. This techniques icompatived reserves both interr and exteriour finrishes. It.

Exterior Insulation with Brick Finish (EIFS with Brick Ledge)

A less but highly effective method involves applicying a continuous layer of insulation over thee existing brick wall on thee exterior, then finishing with a thin brick veneer or brick slip adhered to a base coat.
