Oakleigh Contracts specialises in the rectification of large-scale builds in order to bring them up to the latest fire safety standards. We are able to offer rainscreen cladding due to the compartmentalisation opportunities the structure provides; this means the external wall cladding can incorporate cavity fire barriers, which sit within the cavity.
Cavity fire barriers are non-combustible and are designed to block off sections of a cavity to limit the spread of flames, hot gases, and smoke in the event of a fire. This contributes towards the safe evacuation of a building, as well as establishing entry points for firefighters.
Oakleigh Contracts can work with planners whilst undergoing cladding design and installation, to ensure we meet your preferences regarding the exterior appearance of the building or the requirements of Homes England funding. Whether this is aiming to maintain a similar appearance to the existing exterior, or to update the appearance of the building, we can supply a range of cladding solutions to meet all expectations.
What is the difference between rainscreen and cladding?
The main difference between rainscreen and traditional cladding is the air cavity incorporated into the rainscreen system. Whereas traditional cladding sits directly on top of the load bearing wall and insulating materials, rainscreen cladding is separated from the load bearing wall by a ventilated and insulated cavity.
What are the types of rainscreen cladding?
The two main types of rainscreen systems are drained and ventilated and pressure-equalised.
Drained and ventilated systems feature a cavity which is open at the top and bottom, allowing moisture to drain out of the bottom of the system or evaporate out of the top. The top of the cavity is typically partially covered to prevent excess moisture entering the system.
Pressure-equalised, or PE, systems feature a cavity which is closed at the top, so moisture can’t enter from above. This system still enables moisture to escape out of ventilation gaps, the pressure of which equalises the pressure of moisture being driven in from external forces such as wind.
