Research indicates the market for curtain walling(*) is growing at a healthy rate of around 6% per annum. This is driven both by new build construction and by energy efficient refurbishments of existing buildings.
Standard curtain walling improves the thermal insulation of the building, leading to reduced HVAC costs and reduced heat loss. It also improves the aesthetic appearance of the building.
A photovoltaic curtain wall has the added benefit of generating electricity over the building’s life.
Whilst it costs a bit more than standard curtain walling, the incremental cost of a photovoltaic façade will typically be paid back within around five years.
