1 SKYTEX Light and Ventilation Ridge Agricultural product for Light and Air

2 2 Light and ventilation ridge SKYTEX light and ventilation ridge letting the light in and the air out for more milk A light ridge must fulfil two functions in that it needs to deliver more light into livestock housing and also extract spent air. Both of these requirements are ably achieved with our unique SKYTEX light ridge! SKYTEX provides optimal lighting and ideal ventilation along the entire length of the building and over a width of 4-7 m. A special two-ply sheet diffuses daylight throughout the shed and simultaneously prevents direct sunlight from heating up the building. The inner woven sheet is extremely weather-resistant and fully UV-stabilised. Application of the sheet is based on decades of agricultural building technology experience. The outer protective mesh fabric provides both maximum stability, including under extreme snow loading, and optimum mechanical protection even against the sharpest bird claws. Light on the inside and dark on the outside, the ridge fits harmoniously into its environment. High wind deflectors and large openings ensure constant air extraction. The wind deflectors channel the flow of air around the openings, consequently drawing the spent air out of the shed. A robust arch assembly reliably accommodates the highest structural loads (Fig. 1). Spent air Wind Bright light and fresh air are essential for milk production and cost nothing, we just have to let them in! light Fig. 1

3 3 Why use a wide light ridge? An essential component for both milk production and livestock health, in modern livestock housing light is generated through the use of intensive lighting systems. The aim is to keep lactating cows at over 200 Lux for 16 hours and in the dark for 8 hours, while the opposite is recommended for dry cows 8 hours of light and 16 hours of darkness. But what is the point of burning watt-hungry lamps all day when 20,000 Lux is available free of charge above the roof? Many livestock shed owners are already using natural light through the roof membrane via transparent PVC roofing sheets; however, these sheets only deliver a narrow shaft of light straight downwards, which unnecessarily heats up the interior. The outcome is heat stress! (Fig. 2). Spent air must be extracted from livestock housing. An open ridge is certainly the simplest form of construction, but only works with high wind deflectors. Darkness and the ingress of rain are other disadvantages (Fig. 3). Fig. 2 The solution: The SKYTEX light ridge broadly diffuses light throughout the shed using special sheets. This is achieved with the special sheets, an arched construction shape and an exceptional ridge width of up to 7m. (Fig. 4). Warming is limited to the area directly below the sheet, with the warm air escaping immediately with the air vented through the lateral ridge openings. The rounded construction and slanting wind deflectors cause the wind to flow gently and turbulence-free over the shed in an arch, effectively drawing the spent air out of the building. Brushes on the bottom edges close off the gap between the wind deflectors and roof membrane. Fig. 3 Benefits: Diffuses light broadly throughout the shed Opening width 4-7 m No greenhouse effect Extremely robust thanks to woven fabric and arches Effective extraction due to high wind deflectors Fig. 4 Lighting from lamps requires 16 hours of electricity per day to complete a lighting programme. Daylight through the roof membrane is unlimited; we only have to let it in.
