Six blocks of sheltered housing accommodation owned by Bournemouth Borough Council were in need of a smoke ventilation system. The project was carried out to replace older ventilators that were proving unreliable and did not meet current requirements for energy performance.
Powrmatic Krystalite louvres were selected from a shortlist following a tender exercise by Bournemouth Borough Council, and installed by Dorset Electrical and Fire Alarms (DEFA). They are located at the ends of corridors and stairwells, providing natural daylight and ventilation to common areas, with automatic smoke and heat ventilation in the event of a fire.
Each ventilator is equipped with a manual switch for residents, as well as rain and wind sensors to automatically close the louvres in bad weather. In addition, the warden has a manual override function to close the louvres at night, safeguarded by an anti-finger trap facility.
Krystalite ventilators feature high levels of thermal insulation, combined with a polyamide thermal break to minimise energy losses. Consequently, Bournemouth Borough Council will benefit from improved energy efficiency while ensuring the safety and comfort of its residents.
