Timber is such a plentiful andversatile construction material thatallows manufacturing andconstruction flexibility as well ashaving real benefits over man-madealternatives.

Firstly, timber has a natural warmth and beautythat provides a real aesthetic advantage whencompared to conventional block or brickstructures. The timbers we use are from slowergrown trees, producing a dense make up withexcellent straight grain. Any splitting anddistortion is minimised, allowing your timberbuildings to keep their natural good looks fordecades.

Environmentally, timber is also the best choicefor us all. The great majority of Europe’s forestsare now sustainably managed and growing insize, supplying high quality softwood timbers ina responsible manner.

As a building material wood has the lowestenergy consumption in its production as well asthe lowest carbon dioxide emission. Timberbuildings act as a ‘carbon sink’, actually lockingin CO2 into their structure.

Wood has a superb natural thermal efficiencywhich increases with the thickness of thetimber, reducing the cost of heating andinsulation materials in a building.

Timber is very strong. In relation to its weight,timber is stronger than any other buildingmaterial, producing lighter buildings andsimpler foundations.

With the development of effective preservativetreatments, timber can have a greatly extendedservice life, even when exposed to the harshestof weather conditions.

The majority of timbers used in our Challowbuildings are pressure pre-treated with thelatest generation of wood preservative to give ourselves and our customers a real confidence

in their long term performance. Finally, andprobably most important of all, timber buildingsare more cost effective to construct. Timberoffers a 30% more predictable constructiontime than block or brick work and beingrelatively light in weight, provides reducedtransport costs.

Timber is the natural, high performance andaffordable choice for your next building.

Central feed passages can easily be designedinto the interiors for livestock management, asrequired.

The low pitch angle of the roof pitches keepsthe ridge height on the buildings relatively lowand reduces any impact of the structure on thelandscape.

This aspect, together with the natural look ofthe buildings, allows regular approvals fromplanning authorities.

Challow agricultural buildings are designed tobe simple to erect and extend. We offer acomprehensive design service and a full erectionpackage is also available using our own fullytrained and experienced staff.

Internally the width of the bays can be variedand also sectioned with double sided exteriorplywood dividers. These can be to a height of1200mm or to the full height of the building toprovide separate and private tuition areas.Bench seating constructed from pressuretreated timbers can also be incorporated intothe design.

The roof design is a box profile ‘Plastisol’ coatedsteel sheeting with shadowline typebargeboards and PVC guttering and downpipesystems.

Optional lean-to buildings can be incorporatedinto the building structure to securely housefacility equipment.

A welcome addition to our range oftimber buildings, this stylish timberframed garage incorporates a substantial loft facility.

The design creates four 3m ground floor bays,one with robust timber doors. The externalstairway which leads to the loft can help createan ideal office area or the loft space can simplybe used for storage.

All the structural and external cladding timbersare pressure preservative treated to ensure along and low maintenance service life and theroof material is hard wearing, reconstitutedslate and incorporates three skylight windows,together with all the necessary PVC gutteringand downpipes.

Inside the loft there is an 18mm plywood floorand a large casement window in one gableend. The roof area and walls are insulated with100mm thick high performance quilt materialand then lined with 9mm plywood.

Within the loft there are two framed, ledgedand braced doors complete with standard doorfurniture.

General InformationPLANNING APPROVAL Many kinds of buildings and structures canbe built without the need for planningpermission. However, because the planningrules and regulations are continuallyreviewed, in the first instance we wouldstrongly recommend contacting your localplanning department. They will be able toadvise if you are permitted to build astructure without permission or whatprocedures must be followed if permission is required.

MAINTENANCE AND DECORATION

Treated TimbersThe majority of external timbers used in thedesign of Challow buildings are preservativepressure pre-treated to ensure a long termprotection against all forms of wood decay andinsect attack and provide a greatly extendedservice life for the building.

Initially the colour of the treated timber will be

a natural pale green. Upon exposure this greencolour slowly weathers to a warm honey brownand in the longer term becomes a natural silvergrey.

Although treated timber can be decorated ifdesired, it does not have to be painted orstained to maintain its preservative properties.

If treated timbers are to be painted, stained orvarnished we would always recommend a highquality, high performance coating. Always consult the coating manufacturerrecommendations before applying a coatingproduct to pressure treated timber and followthe manufacturer’s instructions, taking note ofthe recommended maximum moisture contentof the timber and subsequent maintenancecycles. Before applying a coating, the treatedtimber should be dried throughout the crosssection.

If waterbased coatings are applied, somediscolouration may occur in exceptionalcircumstances. If this happens, allow the

coating to dry completely. Then apply anadditional coat of product, preferably one witha high build, high solids content.

If any cuts or notchesare made to any of thetreated timbers of thebuildings, the area oftimber revealed mustbe liberally brushedwith a suitable end-

grain preservative, such as Ensele, to maintainthe integrity of the preservative protection.Always follow the instructions on the can.

Untreated TimbersSome external timbers in Challow buildings aresupplied untreated, for instance doors andwindows and Log Cabin profiles. In thesecircumstances we would recommend theapplication of a high quality, high performancedecorative coating, preferably with a high build,high solids content. Always consult the coatingmanufacturer recommendations on applicationand subsequent maintenance.

Metal Fixings and FasteningsBecause the treated timber used inChallow buildings has a long lifeexpectancy we use metal fixings andfastenings that have a comparablelength of life and will not requiremaintenance.

Roof MaterialsRoofs should be checked on a regularbasis to confirm that no movement ordamage to the materials have beencaused by the weather or physicaldamage. Any damage should be repairedas soon as possible.

Gutterings and DownpipesThe drainage systems used on Challowbuildings are all PVC based. Regularchecks should be made for cracks andjoint breakages and repaired as soon aspossible. Regular checks should also bemade to ensure there are no blockageswithin the guttering and downpipes.
