A recent study by leading construction consultants, Davis Langdon, found that the additional cost in using CO² blown extruded polystyrene compared to Jablite modified expanded polystyrene ranged from 10.2% to 22.9%.
“We had an inkling that our insulation was more economic than some of the competition, but we wanted it checked out by an independent, well-respected organisation,” explains David Teasdale, Sales & Marketing Director.
Jablite asked Davis Langdon to conduct an independent cost comparison using their own case studies and industry research. The results can be seen in a detailed report on Jablite’s website.
Davis Langdon found three reasons for the lower costs, they are:
- The better thermal conductivity of modified EPS bead over CO² blown XPS, allowing for thinner boards to be used.
- The greater variety of board thicknesses available in modified EPS bead modified EPS bead is available in 5mm increments, CO² blown XPS is generally available only in 20mm increments.
- CO² blown XPS is generally only available in board thicknesses up to 200mm; modified EPS bead is available up to 250mm thick.
