From Parent to Great-Great-Grandparent stock, Harlows are able to design the correct environment for all of today's most valuable pedigree breeding stock, helping to ensure the best conditions possible for maximum egg production.
Internal layouts of nests, slats, ventilation, feeding and water are all taken into account during the design consultation phase.
Special light baffling to inlet vents and fan housings excludes light during the rearing and laying stages, yet is simply removed for ease of cleaning.
For commercial pullet rearing we can also design housing to take account of the slatted platforms used during perchery training and can accommodate the various types of ventilation systems available.
Harlow poultry houses are designed and constructed by a highly skilled and experienced workforce.
Construction begins in our CAD drawing office where plans are made for our extensive Mill to cut and pre-assemble the building panels. These are then quality checked before being loaded onto our own transport and delivered directly to site. From here, our professional erection teams will unload our vehicle and complete the construction process with care and attention.
All our buildings can be constructed with timber or steel portal frames and clad with timber weatherboard or on occasions, steel profile sheeting.
Having built timber Poultry Houses for over 80 years, our reputation for building quality is recognised throughout the world.
All our exterior timber cladding, including sole plates and door posts, are pressure treated in our own treatment plant with Wolmanit CX then left to cure and dry.
This ensures the treatment lasts for the life of the timber and gives a pleasing golden brown finish - as an alternative, steel profiled sheeting can be used for the external cladding. All the timber is machined and supplied from our own Mill in Long Whatton, Leicestershire, enabling us to maintain a very high standard of quality control.
Roof sheeting is supplied in a variety of colours, being galvanised then usually polyester coated.
Roof insulation is with fibreglass which we seal in a polythene enclosure before laying. This ensures the prevention of moisture absorption or dust build up and maintains effectiveness.
Wall insulation is also by fibreglass which is attached to each panel before despatch to avoid any vertical movement. Once a design is agreed, we provide full specification drawings suitable for Planning Applications along with detailed foundation plan drawings for your basework.
For larger turn-key projects, we can be employed as main contractor to take care of everything from site clearance to finished farm ready for livestock.
All Harlow housing can be supplied as clear span. Up to 40 feet wide with low cost timber trusses, or over 40 feet steel portal frames.
The vertical steel stanchions are galvanised and the rafters are zinc phosphate coated.
Once the steel frame is erected, the external cladding can be traditional timber or profiled steel sheeting.
Internally, the roof lining is profiled steel, but the walls are lined with fireproof and waterproof fibreglass resin board. This ensures that where the lining board can come into contact with the livestock, the board will not rust, is hygenic and can be easily cleaned. Insulation throughout the roof and the walls is with fibreglass, incorporating a polythene vapour barrier.
Once your individual design is agreed, we will provide you with full specification drawings suitable for your Planning Applications. For larger turnkey projects we can be employed as main contractors to take care of everything from site clearance to finished farm ready for livestock.
Our experience of designing houses for many Countries throughout the World from Saudi Arabia to the Falklands, helps us to provide you with the correct system for your needs.
Correctly designed ventilation is of vital importance to the modern Poultry Farmer.
We offer advice on the most suitable system which generally falls into either Controlled Ventilation or Natural Ventilation utilizing our comprehensive range dependent upon site location and intended use.
The most modern method of moving air efficiently is through a round tube, and Harlow Bros have designed a circular acrylic fan shaft liner which can be fitted inside the plywood fan shaft to offer greater airflow, ease of cleaning and fully insulated walls.
The shaft tops have a polyester coated smooth steel cover and can be supplied with deep sides for extra light baffling.
Inside the house, we offer various designs of back-draught shuttering, fail safe openings and under-tray housings.
Harlows are also just as happy to install plastic type chimneys, supplied by other Climate Control Companies.
All Harlow shutters are insulated and fitted with draught excluders. Air inlet shutters are operated either manually or automatically using a rack and pinion mechanism. This offers a very fine adjustment helping to reduce draughts and give the best possible supply of fresh air to the livestock.
The shutter can be single type, hinged at the top or bottom, and also double type with a second row of shutters underneath, to direct air down over the birds on hot days. The bottom row is usually operated by hand, but can be automated if desired.
In Naturally Ventilated Buildings, the centre hinged shutters in the ridge are also connected to a rack and pinion mechanism, operated by a hand or motorised gear winch.
External air baffles are important to help guide the air into the house, protect the shutters from weather extremes and offer a convenient way of light proofing the building.
All Harlow baffles take these factors into account, with our comprehensive range offering different advantages, with most offering ease of cleaning and a minimum restriction to the air flow.
