Bilco UK - Roof Access Hatches

Roof Access - Smoke Vents - Bilco - Hatches

The Bilco Company has served the building industry since 1926. During these years it has built a reputation among architects, engineers, and the construction trades for dependability and for products that are unequalled in design and workmanship.

Manufacturing

Based in Suffolk, Bilco UK can supply the trade with a range of standard roof hatches, smoke vents and floor doors in various sizes, and materials direct from stock. If a special is required our fast track shop allows us to deliver in an industry leading 4-6 weeks. Our quality access products comply with current Building Regulations and legislation and are engineered to provide many years of trouble free service. All products come with a minimum 10 years warranty.

Natural Smoke Vents

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 Construction Products Regulation (E.U. no. 305/2011) came into force in the U.K. and it is now mandatory for smoke vents to be C.E. marked and to be supplied with a Declaration of Conformity. Bilco smoke vents have been fully tested and are C.E. marked making them fully compliant with this new legislation.

The Bilco REM single leaf ventilator opens to the fire open position of 140° within 60 seconds, meeting the requirements of Approved Document B and EN12101-2 to ensure rapid dispersal of smoke and noxious fumes. 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.

Bilco are also able to supply the essential control equipment to enable control of the ventilator for smoke control, comfort ventilation or access.

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 are manufactured to provide a high degree of thermal efficiency and are supplied with 50mm of polyisocyanurate insulation to both the up stand and the cover. In addition the cover is fitted with a closed cell EPDM gasket designed to reduce the air leakage though the closed cover ensuring the air leakage requirements of Building Regulations Part L are achieved. 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.

The acoustic, thermal and air leakage performance of these 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

Floor Access Doors

Pit and floor doors provide access to equipment stored underground or below/between building floors. Products include drainage doors, non drainage doors, doors that receive flooring materials, doors for interior applications, fire rated doors, and special application doors.

The doors are available to suit a range of loading capabilities and are all fitted with the unique counterbalancing spring mechanism to ensure that doors are easily operable within the Manual Handling Regulations.

Floor Access Covers

Floor Access Covers

Bilco floor access covers are designed to provide convenient, direct access to underground areas and services, while blending in with the surface in which they are laid. The covers incorporate metal pans, which accept a wide variety of floor materials, allowing them to go virtually unnoticed in the surrounding floor. Typical applications include airports, underground railways, warehouses, hospitals, retail outlets and general commercial building interiors.

Pan Covers

Shallow-pan, standard-pan and deep-pan covers are supplied in pan depths from 27 to 102mm. Available in lift-out and hinged designs, they are suitable for all kinds of horizontal access applications.

Fire-rated Pan Covers

BV-F90 fire-rated covers are certified to resist fire for 90 minutes following a live test by the Institute of Fire Protection Technology & Safety Research (IBS).

Insulated Pan Covers

BV-Thermo insulated covers incorporate an insulation plate with thermal properties as follows: resistance 3.2m2K/W; co-efficient 0.3W/m2K.

Sealed Duct Covers

BVA sealed duct covers are suitable for continuous access to pipes and cables. They are available in two- or three-part assemblies, which feature demountable cross-beams that can be removed without tools. Systems can be specifically designed for longer runs.

Operation

All covers have a tapered profile that makes them easy to remove and operate, and secure when closed. They are also available with a hinged design that features lift assistance for applications requiring regular opening with minimum effort. Lift-off covers use a 'golden key', which is inserted into one of the four corner keyways on the cover. The unique shaft design breaks the seal between the cover and the surrounding frame. This, coupled with the tapered profile of the cover itself, allows even a 'sticking' cover to be easily removed from the frame. The keyways also provide lifting points. Each cover comes with two keys to enable it to be moved easily to one side to provide access to services or underground space.

Composition & Manufacture

Panels are available in 2mm-thick cold-formed, galvanised mild steel, in grade 304 stainless steel, or in aluminium. Available in a range of depths, covers are precision manufactured, and some feature a full EPDM seal that is capable of withstanding up to a 1000mm head of water.

Finish & Appearance

Cover pans are available in four depths - 27, 50, 66 and 102mm - to accommodate brick, concrete, paviours, tiles, carpeting or other materials, allowing panels to merge with factory and warehouse floors.

Safety Products

Bilco offer a range of safety products including Ladder Up Safety Posts to provide a hand hold for persons mounting or demounting a fixed vertical ladder and a products to provide fall protection around openings in the roof or the floor.

Technical Support

Bilco's dedicated support team are available to provide UK coverage for all technical enquiries relating to access or smoke ventilation solutions.
