  • ProAir Venting

Overview
Ventilation louvres can be applied to Profarm, Procolor and Proclad to allow airflow. Both the 1000 mm and 800 mm cover widths can be vented.

Mainufacturing Details
The diagram below illustrates some of the capabilities and limitations in relation to venting.

Duggan Steel - ProAir Vented Sheeting Profile

Standard Vented Area
Unless indicated otherwise at time of order the maximum possible area of the sheet will be ventilated, i.e. venting will start 100 mm from top and extend to 200 mm from bottom with vents spaced at 40 mm.

Available Lengths
Maximum length: 6 m
Minimum length: 610 mm

  • Non Drip

Overview
NonDrip condensation control membrane is specially designed to help control condensation and prevent dripping in non-insulated metal buildings. It can be applied on our range of 14/3 corrugated or 1000/32 box profile sheeting.

Application
NonDrip membrane can help control condensation in an environment where the condensation appears cyclically. In order to work it needs to get dry in between cycles so it should not be used in buildings where relative humidity approaches saturation for extended periods. To facilitate drying adequate ventilation is necessary. Without proper ventilation the risk occurs of the build-up of moisture and droplet formation.

Installation
Care must be taken to avoid penetration of rainwater due to capillarity through the side or end laps. The following should be observed during installation:

Vertical overlaps (A)
All profiled sheeting with NonDrip is supplied with the vertical side lap left uncovered. The capillary effects in the lateral direction (A) can be prevented by installing sheeting so the interior side is completely covered with NonDrip membrane (no bare metal visible).

End laps at (B) and (C)
Sheeting is supplied with the NonDrip membrane flame sealed (burn back) at one end. To avoid penetration of rainwater due to capillarity through horizontal overlaps B and C the following should be observed:

  • The burn back should be at the downslope end of the sheet.
  • The overhang of the eave above the gutter should be at least 15 cm to avoid rain water penetrating into the building. This part of the roof is permanently ventilated in the outside air.

Ventilation
Key to the working of NonDrip™ is sufficient ventilation within the building envelope, to allow it to dry. The air flow movement and temperature within the building structure, will determine how quickly the NonDrip™ membrane will return to its original dry state.  The build up of condensation can be reduced in the first place by the use of natural ventilation provided by eave, ridge and wall openings.

Absorption capacity
The water absorbency rates listed below were found from laboratory testing. As the roof pitch increases the absorption decreases under the influence of gravity.
Absorption & Drying Properties

Absorption at roof pitch Unit Value Conditions
Absorption at 0 degree* g/m² 1037 100%RH, ΔT:17°C
Absorption at 10 degreeg/m² g/m² 716 100%RH, ΔT:17°C
Absorption at 30 degree g/m² 538 100%RH, ΔT:17°C
Absorption at 45 degree** g/m² 394 100%RH, ΔT:17°C
Drying speed*** g/m²/h 80 50%RH, 23°C

*With the sheet laid flat, and the relative humidity within the building at 100%,and the temperature on the inside of the building 17°C higher than the outside temperature, 1037 g/m2  water was absorbed by NonDrip before it started to drip.

**This is an average time to drip for a roof pitch of 20 degrees given the relative humidity within the building at 100%, internal temperature of 40 degrees and the temperature on the inside of the building 17°C higher than the outside temperature. If the roof pitch is increased the time to drip will be somewhat shorter while lower angles will exceed 6 hours.

***With the relative humidity within the building at 50%, and the temperature on the inside of the building at 23°C, the drying speed was 80 g/m2/h.

Clearlights
Due to the risk of droplet formation on the underside of the light, clearlights are not recommended on a roof with NonDrip.

Purlins
All prepainted metal sheets, including those with NonDrip, should be separated from wet, green or treated timber purlins by a DPC strip.

Corrosion resistance
NonDrip™ does not negatively impact the corrosion resistance of the sheeting to which it is applied. The value of any guarantee supplied with sheeting will not be affected when NonDrip is used.

Chemical resistance
NonDrip should not be exposed to any solvents. Special care should be taken when using disinfectants. The disinfectant to be used should be tested on a small area to verify its effect. High pressures or hard brushes should not be used on the NonDrip membrane.

Installation precautions
To prevent damage to the NonDrip™ membrane, avoid rubbing the sheets together or against the roof structure.
