Roofing Accessories
Roofing accessories are any fixtures or structures that are an integral part of the roof itself or are incorporated later into the roof. Roofing accessories are generally functional in nature and ensure that the roof protects the building and its inhabitants from the elements. For the roof to be waterproof it has underlayment, which is a secondary water-resistant barrier laid under the external roofing material. In order to install some roofing materials, fasteners such as nails or staples are necessary. All roofing must have some kind of drainage system to ensure that rain does not seep through the roof causing structural damage. These systems are a form of guttering and water pipes to take the rain away from the walls. Water diverters are installed around chimneys and other roof projections whilst a drip edge extends over the eaves. These roof projections may be chimneys or roof vents, which are part of the building's ventilation system. Some roofs might also have a window roof especially in converted attics. Roofing accessories are installed in all buildings, whether they are residential, commercial or industrial. The type of accessories depends on the building's heating and ventilation system as well as its architectural design and roofing materials.

Bilco UK Ltd
View company profileThe Bilco Company was established in America in 1926 and has for many decades designed and supplied access products for construction and engineering industries all over the world.
In 1989, Bilco UK & Europe was formed and has built a reputation amongst architects, engineers, specifiers, and the construction trades for providing the right access solution.
In fire situations, most deaths and injuries are caused by fumes and smoke, not flames. Having an efficient and effective means of ventilating smoke and noxious fumes saves lives and can assist the emergency services greatly in facilitating fire fighting and evacuation.
Bilco smoke vents are designed to satisfy Building Regulations and meet Approved Document B, BS 9999 (which supercedes BS5588) and European Standards enshrined in EN 12101. As of 1st July 2013, the Construction Products Regulation came into force which requires smoke vents to be CE marked and to be supplied with a Declaration of Conformity. Bilco smoke vents have been fully tested and carry the CE mark as required by the new legislation.
For the EN 12101 key areas of the regulations are that the covers must reach the fire open position within 60 seconds and that single covers open to 140° to ensure there are no negative wind coefficients ie wind blowing smoke back into the building.
Bilco smoke vents are also compatible with other guidance and codes of practices, for example those issued by the British Research Establishment such as BRE 79204.
