BILCO supplies Roof Access Hatch and Smoke Vent to the Brentwood Community Hospital, Essex, as part of the new hospital's fire safety systems.
Access hatch manufacturer BILCO UK supplied Roof Access and Smoke Vent solutions to Brentwood Community Hospital.
The hatch and vent are vital parts of the hospital’s fire safety systems.
The Brentwood Community Hospital is a new building on the site of a former hospital. The two-storey building includes a 50 bed inpatient ward as well as outpatient and radiography facilities.
BILCO has supplied a 1,000 x 1,250 mm EW-50 REM Smoke Vent with increased thermal insulation and reduced air leakage, and a 915 x 760 mm S-50T Roof Access Hatch with its LadderUP Safety Post, to provide a secondary means of escape from the flat roof area.
INSULATED COVER AND CURB
BILCO Roof Access Hatches are fitted with 50mm thick faced rigid polyisocyanurate insulation board to both the cover and curb. Super TUFF-R has a component U value of 0.47 Wm²/K and is ideally suited to accepting a variety of roofing adhesives. It is made with hydrocarbon blowing agents to ensure that its manufacture does not deplete the Earth’s atmospheric ozone layer.
CLASS 1 RATING - BS EN 12207:2000
All BILCO Roof Access Hatches are fitted with a specially designed closed-cell EPDM sponge gasket to provide a better seal of the cover to the curb, and help meet Building Regulation Air Leakage targets. Independent tests have shown that the maximum air permeability performance at pressures up to 600 Pascals is less than 4.83m³/hour/m² – giving the hatches a Class 1 rating under BS EN 12207:2000, and helps architects and engineers meet the requirements of Part L of Building Regulations.
TESTING DOCUMENTATION AVAILABLE
The acoustic, thermal and air leakage performance of the hatches as well as their resistance to wind and snow load and to impact, has been independently verified by tests at Taylor Woodrow’s Technology Centre in Bedfordshire. BILCO can provide full test results for inclusion in building documentation.
The design of hinges and other features ensures that the hatches are resistant to the effects of ageing and weather in exposed locations.
