Habitable roof space

People are driven to demand habilatble roof space by various forces.

Demands for higher housing densities and a reduction in footprint size forces builders to build up or down to put floor area into houses. Homeowners on the other hand want the extra space for a home office, a guest room or a play room.

The Kingspan TEK Building System is ideally suited to the creation of a room in a roof. The System's roof and wall panels can achieve U-values of as little as 0.16 W/m²·K as standard but can achieve 0.10 W/m²·K or better with extra internal insulation.

Floor space

A lower thermal conductivity can result in a thinner insulation. A thinner insulation can result in a thinner external wall construction. A thinner external wall construction can result in greater internal floor area. A greater internal floor area can result in a greater return on investment (ROI).

The usable space within a building is a fundamental metric in understanding the valuation of real estate. Properties with greater internal floor areas command a higher return in addition to a higher overall financial value, so could give rise to a greater ROI.

The width of external walls incorporating the Kingspan TEK Cladding Panel is thinner than comparative solutions – allowing for internal space gains without having to increase the overall designed footprint of a building.
