 Our innovative-patented product provides ventilation at eaves level, and offers maximum airflow into the roof void. It is the only product of its kind on the market, has NHBC approval, and meets all the requirements of the new Part L Building Regulations.
Please use this website to view, in detail, the benefits and solutions provided by the Airtrac tray. We currently supply some of the largest house builders in the UK, as well as contractors, roofing companies and self-build projects.
If you would like to place an order or have any questions, please do not hesitate to contact CK Supplies (UK) Ltd. Airtrac is an environmentally friendly eaves ventilator that allows for the 'higher insulation' requirement of the new building regulations.
 Designed to allow maximum ventilation using innovative new design features, our eaves ventilator product meets all the requirements of the new Part L Building Regulations. It is easy to install and costs no more than some inferior products currently available.
The Problems
Many eaves ventilators currently available are not fitted in the correct position, which either blocks the ventilation path into the roof void or prohibits the ceiling insulation being carried over the wall plate. This causes a cold bridge in the most vulnerable part of the building and therefore fails to comply with the latest regulations, with subsequent cost and environmental implications.
▪ | The importance of the regulations are not always understood | ▪ | Products that were designed years ago are not adequate for current insulation standards. | ▪ | Cold bridges are formed in the most vulnerable part of the building. | ▪ | Ventilation path to the roof void is blocked | ▪ | Many products currently available are flimsy and do not give adequate performance. They are often installed incorrectly | ▪ | A number of current eaves ventilators fail to direct the ceiling insulation. |
Building Regulations - Approved Document F1 - F2
Condensation in Roofs
F2. Adequate provision shall be made to prevent excessive condensation - a) in a roof; or
b) in a roof void above an insulated ceiling
BRE Report - Thermal Insulation: avoiding risks
2.1 (c) Provide an air path to the roof space from the eaves ventilation opening equivalent to a 50mm continuous gap.
2.3 Condensation of Thermal Bridges
2.3 (a) Carry the loft insulation over the wall plate to link with the cavity insulation.
NHBC - Thermal Insulation 7.2 - S.14
▪ | Cross Ventilation of the roof is provided | ▪ | Insulation does not block the ventilation path at eaves level | ▪ | Insulation is laid over the whole loft area, including the wall plate | ▪ | There are no gaps in the insulation |
Global Warming is a worldwide problem!
The Airtrac Rafter Tray can have a positive effect in reducing energy waste. The Airtrac Tray can have a significant effect on heat loss and as a consequence save millions of litres of fuel.
Failure to comply with the regulations will result in the very problems they were designed to prevent.
The Result:
▪ | Cost to the home owner | ▪ | Environmental Impact | ▪ | Cost to the Builder | ▪ | Claims against the NHBC | ▪ | Condensation in the roof void |

Heat loss and energy wasted through a cold bridge will be a huge cost to the home owner. On an average semi-detached house the cold bridge is approximately 6 square metres. This is equivalent to roughly 15% of the total roof area. The loss of heat through such a large area equates to millions of litres of heating oil every year. This is an enormous waste of fossil fuels that can be prevented easily and cheaply using the Airtrac rafter tray.
