Bilco UK - Natural Smoke Ventilation & Roof Access

Natural Smoke Ventilation - Roof Access - Ladders - Bilco

BILCO serves the commercial and construction sectors in the UK with permanent, safe access solutions for all areas of the building. Formed in 1989, we have built a reputation amongst architects, engineers, specifiers, and the construction trades in the UK for providing high quality, reliable and safe roof and floor access solutions.

In March 2017, Howe Green was acquired by the home security specialist ERA and now operates alongside Bilco UK. The BILCO and HOWE GREEN brands offer the building services sector a comprehensive range of roof hatches, smoke vents, floor doors, floor access covers, wall access hatches, ceiling access panels and ladders to facilitate the safe access of all areas.

Natural Smoke Ventilation

Natural smoke vents help remove smoke and gases from burning buildings, primarily to provide clearer escape routes for people within the building. They also aid firefighter’s visibility when entering the building to tackle the fire and reduce the lateral spread of the fire; important to reduce the damage to the building and its contents. Used widely in the stairwell, corridor, smoke shaft and on roof areas of factories, warehouses, auditoria and retail facilities.

As of 1st July 2013, the EU Construction Products Regulation No. 305/2011 came into force in the UK and it is now mandatory for smoke vents to be CE marked and to be supplied with a Declaration of Conformity. Bilco smoke vents have been fully tested and are CE marked making them fully compliant with this new legislation.

The Bilco REM single leaf ventilator opens to the fire open position of 140 degrees within 60 seconds, meeting the requirements of Approved Document B and BS EN 12101-2 to ensure rapid dispersal of smoke and noxious fumes.

Double leaf vents for larger ventilation areas are manufactured to open to 90 degrees. In addition, the construction of the ventilator includes rigid polyisocyanurate insulation to the cover and the curb to provide maximum thermal efficiency and a closed cell EPDM gasket to ensure the air leakage requirements of Building Regulations Part L are achieved. Their design means that nearly all REM vents can be used for access onto the roof area and can also be linked into the BMS for comfort ventilation.

Roof Access Hatches

Roof access hatches provide safe and convenient access to the roof areas for routine maintenance and inspection as well as for servicing of HVAC systems and other roof mounted equipment. They are ideally suited for use in office buildings, flats, factories, warehouses, retail stores, shopping complexes, hotels, manufacturing plants, hospitals, schools, auditoria and sports facilities where roof access is a requirement.

The wide range of stock sizes will provide access solutions for ladder, ship stair and full sized stairways, or for equipment access applications. Standard sizes are available ex stock and are generally delivered to site within 2-3 working days.

All Bilco roof hatches provide a high degree of thermal efficiency and are supplied with 75mm of polyisocyanurate insulation and manufactured with thermally broken construction. The unique counterbalancing spring mechanism ensures that all hatches are easily operable by one person to assist designers and employees in meeting the requirements of the Manual Handling Regulations.

Fixed & Retractable Ladders

Bilco’s range of fixed vertical ladders are available in either aluminium or galvanised steel and can be supplied with safety cages and guard rails as necessary. Our standard range has ladders up to a height of 6.0m but special sizes are available on request. All our fixed ladders are manufactured to BS 4211:2005.

The retractable ladders can be supplied with or without a trap door and lining and a fire rated option of F30 or F90 is available. Other options include telescopic handrails, opening from above and electronic operation. All retractable ladders are manufactured to BS EN 14975 (DN 4570) and we also have a range of roof walkways, step over ladders and edge protection.

Additional Products

Bilco can also supply a range of floor access doors and floor access panels as well as a range of safety products to offer fall protection and easier means of access when using fixed ladders.
