Information about the Roof and wall structure:

Genugten Agri B.V. delivers complete steel structures with timber or steel purlins. Various types of steel profiled sheets, sandwich panels, eco panels, but also traditional corrugated sheets are delivered for roof covering. A wide range of insulating materials is available for roofs, such as glass wool blankets and PU and PS insulating sheets. To construct the outer walls, Genugten Agri B.V. delivers precast insulated concrete elements, sandwich panels and steel profiled sheeting. And for the inner walls of the pig house, we are your contact for different types of plastic sections and panels which can be installed in stainless steel sections.

Roof covering

Various types of steel profiled sheets, sandwich panels, eco panels, but also traditional corrugated sheets are delivered for roof covering.

Steel purlins

The use of steel purlins enables a greater span to be created. As a result, the number of roof trusses required will be lower and they can be placed further apart, enabling wider rooms to be constructed in the house. Steel purlins, which can be used for spans of 6 to 10 metres, are light and easy to install.

Steel profiled sheets

We supply steel profiled roofing sheets. Not only do steel profiled sheets weigh less, but they are also suitable for larger purlin distances of 1.5 to 1.8 metres. In addition, the price per m² of roof will be lower than with conventional corrugated sheeting, because it is no longer necessary to take a 15% overlap into account. If required by the customer, the sheets can be supplied with thick plastisol coating in various colours. This coating is guaranteed for 10 years. The sheets are delivered to a length of maximum 15 metres, enabling very fast installation. If local government regulations require corrugated sheeting to be installed, we can supply black steel corrugated sheeting. Glass wool insulation blankets are the most suited for roofs with steel profiled sheets.


Sandwich and eco panels

Sandwich or eco panels can be chosen to insulate the roof. The most commonly used panel thickness is 60 mm, but 40 and 80 mm is also possible. These panels enable a high-quality insulation to be created. In addition to quick installation, the use of these panels also allows a greater purlin distance, enabling further savings on the costs of installation. The sandwich panels have steel profiled sheets of various thicknesses and coating materials on both sides. The underside of eco panels is finished with aluminium foil instead of a steel profiled sheet. This makes these panels less expensive, but this is partly offset by the extra cost of the shorter purlin distance.

Corrugated sheeting

Although conventional corrugated sheeting is used less and less, Genugten Agri B.V. still supplies the complete range of asbestos-free fibre cement corrugated sheets with all the accessories and fasteners required.

Roof insulation

Modern pig houses are fitted with a “SOFT-AIR” ventilation ceiling. Where this ceiling is used, no heat will escape through the roof in cold periods, which means a saving on heating costs. In this situation, roof insulation is only necessary to prevent the air above the ceiling being warmed up too much on hot days. Genugten Agri B.V. supplies a large range of insulating materials for roofs and ceilings.

Glass wool insulation blankets

With this method of insulation, glass wool insulation blankets, with foil on their undersides, are attached over the purlins. The steel profiled sheets are installed directly on top of them. This results in a so-called 'cold roof' structure, which means that the temperature of the roofing sheets fluctuates along with the outside temperature. This prevents condensate from forming on the underside of the sheets. This use of insulation blankets is not possible in combination with fibre cement corrugated sheets, because these sheets require ventilation on their undersides. When using corrugated sheets, battens must be fitted on top of the insulation blankets and the corrugated sheets are installed on top of the battens. Genugten Agri B.V. supplies glass wool insulation blankets of various thicknesses to length and in widths of 100 and 120 cm.

PU insulation sheets

These well-known insulation sheets, with an alukraft layer on both sides, are commonly used in the agricultural sector. These sheets are strong, available in various thicknesses and easy to install. The sheets can be delivered with flat sides, making them suited to the use of plastic H-sections, or with rebates, causing them to partly overlap. These sheets have a good insulation value and are easy to clean. When using a “SOFT-AIR” ventilation ceiling, a sheet thickness of 30 mm is sufficient for roof insulation. When these insulation sheets are used in combination with another ventilation system which works via the ceiling, a thickness of 60 mm has to be selected.

PS insulation sheets

PS insulation sheets can also be used for roof insulation. These polystyrene sheets have a lower insulation value and are much cheaper than higher quality insulation sheets. In addition, higher density polystyrene sheets are available in the most common thicknesses of 40, 50 and 60 mm.

Precast concrete walls

More and more companies prefer to use precast concrete elements. These concrete elements can be supplied with various gravel and brick patterns. The fast construction method enables a lot of time to be saved when using these elements. In addition, these elements enable a very high quality building to be made. These concrete walls are available in different thicknesses, depending on the insulation required. All the necessary openings for windows, inlet valves and doors are already made in the panels during production.


Inner walls

The multifunctional plastic inner walls are easy to install. They are finished with stainless steel sections. These plastic walls are made from first-quality PVC and have a thickness of 35 mm. They are available in different heights in the colours light grey and off-white. Instead of PVC sections, PE panels -which are more stable- can be used to create plastic walls. These panels are 1 metre wide and 50 mm thick.
