Roof Vents
Roof vents are fixtures located on the top of a building. They are used to remove hot air or moisture from the attic and are a part of the ventilation system. They can be motorised, work on electricity or be wind- or solar-powered. The choice of which to install depends on the design of the roof and the home's airflow. There are a variety of roof vents. Box vents are static vents, which means they have no moving parts. They are installed over an opening in the roof and to be effective should be located next to the roof ridge. Off Ridge vents are similar but are rectangular in shape. Ridge vents are also static and run the entire length of the horizontal ridge and are used in conjunction with soffits to ensure an even distribution of temperature. Wind turbines rely on the wind to turn them in different directions. Powered by electricity, Power vents have motors to turn the fans. Soffit vents are placed in the eaves and used with a continuous ridge vent. Roof vents are installed in many buildings to aid the ventilation system so there are no problems with airflow. In this way structural damage such as damp are avoided.

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.
