Outdoor timber that looks great and lasts longer, whatever the season

CarterHoltHarvey Allseasons® for outdoor applications where appearance matters.

The CarterHoltHarvey Allseasons® Outdoor Premium Grade sets the benchmark for appearance and quality in outdoor treated timber. Attention to quality during production and strict observance of visual over-rides for appearance ensures a premium product guaranteed to look great and last longer ... whatever the season.

Allseasons® Outdoor Premium Grade is a popular choice for bearers, joists, rafters and posts for outdoor applications for a number of important reasons: · Aesthetic appeal and visual appearance qualities · Visual over-rides for appearance · Durability - Preservative treated against borers, rot and termites · Manufactured from 100% renewable plantation pine · Seasoned to minimise movement of the installed timber · Consistent sizing · Rougher header finish for ease of handling · Economical and readily available in a large range of sections sizes and in lengths of up to 6 m · Reliable ­ compliance product testing and grade property verification · A great base for popular timber appearance flooring

The Loading Code, AS/NZS 1170.1: 2002, has introduced a reduced imposed loading of 2.0 kPa on domestic decks above 1 m from the ground. This now enables designers and builders to take advantage of the reduced loading and utilise the most commonly used seasoned softwood grades without compromising on the all important appearance and quality. As the timber is for external exposed above ground application, it is assumed that it will be preservative treated to H3 level.

Benefits

CarterHoltHarvey Outdoor Premium Grade is treated to repel termites, fungi and rot, and retains its strength and youthful appearance when properly installed and maintained. Allseasons treated timber is also kiln dried and seasoned which has benefits in dimensional stability. Allseasons strict quality controls ensures an excellent end product.

Why treated timber works the best

Wood deterioration, brought about by insects, rot and fungi, can be prevented if the surrounding conditions are unsuited to the growth of these organisms or if the wood is resistant to them. Timber preservation in a practical sense refers to the improvement to the wood durability by treatment with preservation agents that render the wood highly resistant to insects, rot and fungi.

Product Applications

Outdoor retreats and pergolas

CarterHoltHarvey Allseasons® treated range is suited for all kinds of projects, including retreats like pergolas, gazebos or shade house, outdoor seating areas, ferneries, bird aviaries, tool sheds or dog kennels. CarterHoltHarvey Allseasons® is available in a rougher headed finish for bearers, joists, rafters and posts to ensure consistent sizing and aesthetic appeal. Painting, staining or sealing of Allseasons outdoor timber is strongly recommended for best aesthetic results and minimisation of checking (splitting and cracking), warping & fading.

Technical Information

Good practices to help prevent timber from excessive movement and damage · Specify CarterHoltHarvey Allseasons® for quality kiln dried treated pine. · Make sure CarterHoltHarvey Allseasons® is correctly installed in accordance with AS 1684 residential timber - framed construction standard and safe building practices. · Always use good building practices. · Unless otherwise advised by the paint manufacturers, our general recommendations for external opaque paint finish is a primer/sealer coat followed by two coats of premium acrylic paint. For semi-transparent finish to external timber work we recommend oil-based penetrating stains. · Avoid installing CarterHoltHarvey Allseasons® timber during extremely hot or very wet weather. · Use hot dipped galvanised (or stainless steel) nails, bolts, coach screws and other fasteners. Avoid using gun nails unless your supplier guarantees similar performance. · To prevent wall cladding from cupping, use a breather type sarking such as Tyvek or Flamestop Building Paper. · Protect CarterHoltHarvey Allseasons® by covering it with a canvas or heavy tarpaulin when transporting or storing on site. Store CarterHoltHarvey Allseasons® on timber bearers spaced every meter at least 100mm above ground level. Please remember timber is a natural product with natural characteristics. Incorrect fixing and/or selection of grade can result in a disappointing finish. We recommend that you clearly explain to your CarterHoltHarvey Allseasons® stockist what you want to achieve. Your stockist can also recommend competent tradespeople who can advise on and price your project. For more "Do It Yourself " ideas and project sheets visit www.chhwoodproducts.com.au Check with local and state regulations prior to installation to ensure compliance.

F5 Span Table

Designers and builders can take advantage of the reduced loading introduced by the 2002 version of the Australian and New Zealand Loading Standard (AS/NZS 1170.1, 2002) which introduced changes to the imposed loading for balconies and decks. The new distributed imposed loading on decks is now 2.0 kPa for decks at or above 1 m from the ground and the imposed concentrated load remains at 1.8 kN. For decks less than 1 m from the ground the imposed distributed loading is the same as the internal domestic loading of 1.5 kPa. The existing AS 1684 Residential Timber-Framed Construction Standard is based on the 1989 version of the Loading Code.

Balconies and Decks Floor Joist Spans

The 2006 AS 1684 Residential Timber-Framed Construction Standard is based on the loadings contained in the Loading Code AS1170.1 - 1989. The current Loading Code, AS/NZS 1170.1:2002 has introduced a reduced imposed loading of 2.0 kPa (previously 3kPa) for domestic balconies and decks above 1m from the ground. This guide has been produced so that designers and builders can take advantage of the reduced loading when selecting and using CarterHoltHarvey Allseasons® Outdoor Premium Grade treated pine. For decks less than 1 m from the ground the imposed distributed loading is the same as the internal domestic loading of 1.5 kPa.

ii. Check available joist lengths with your supplier before specifying. iii. While the same deflection criteria used by Timber Solutions © to produce the AS1684 span tables have been used, the resultant deck may exhibit some "bounce". Where this is not desirable, for sizes above 190×35 mm designers and builders may reduce the spans by 500 mm and cantilevers by 250 mm. iv. Maximum deck joist span is based on supporting a maximum decking mass of 20 kg/m2, imposed point load of 1.8 kN, imposed distributed loading of 2 kPa. Suitable for high and low decks. v. Maximum cantilever length is 30% of the backspan. Minimum backspan is 200% of overhang. vi. Joists crippled over supports must be considered as single span joists. vii. Where joist depth is more than 4 times greater than breadth, restraint may be required. Refer AS1684.2 or AS1684.3 Cl. 4.2.2.3. viii. Bearing lengths shall be a minimum of 35 mm at end supports and 70 mm at internal supports for continuous members. ix. Continuous indicates continuous members, i.e. where the joists span over 3 or more bearers. x. NS = Not Suitable, D = member depth, B = member breadth

Personal Protection

Risk

Excess exposure to wood dust from any source has been identified as a potential health hazard. Wood dust is irritating to the eyes, skin and respiratory system. May cause sensitisation by inhalation (asthma) and by skin contact. Repeated inhalation of wood dust increases the risk of nasal cavity cancer and may increase the risk of lung fibrosis (scarring).

Safety

Avoid repeated or prolonged contact with skin. Avoid contact with eyes. Avoid breathing dust. Wear suitable clothing, gloves (light duty leather or equivalent AS2161), and eye protection (dust resistant AS/NZS 1337). Avoid inhaling wood dust and wear a filter mask conforming to AS/NZS 1715 & 1716 while power sawing, machining, sanding or any operation where wood dust is generated. Air extraction in enclosed work areas may be required in some cases. Wood dust can form explosive mixtures with air. Keep work areas clean by wet sweeping and/ or vacuuming. Wash work clothes regularly and separately from other clothes. Wear gloves when handling the material, and wash hands after work and before eating, drinking or smoking.

First Aid

Irrigate eyes with plenty of water. Wash skin with soap and water.

Disposal

Follow above safety instructions. Collect in containers for disposal as trade waste in accordance with local authority guidelines. DO NOT burn treated timber off-cuts or waste pieces for any purpose, as irritating gases are emitted.

Fire

Sawdust may cause an explosive mixture with the air. Earth all exhaust equipment and prevent high dust concentration in confined spaces. Store product in a dry place.
