2. INTRODUCTION | ABOUT US METSÄ WOOD – THE COMPANY: Metsä Wood is part of Metsä Group, a Finnish forest industry group that operates in international markets. Our main raw material, wood, comes from sustainably managed nordic forests where growth exceeds use.

METSÄ WOOD UK: With a long history of supplying timber products for the demanding needs of our construction, industrial, and distribution and retail customers with our operational sites spread across key locations in the UK.

• We use 100% traceable wood from Nordic forests, 84% is from certified forests even though just 10% of the worlds forests are certified • 90,000 private forest owners in Finland • Operating in over 30 countries • For every tree we harvest, 4 saplings are planted in its place • FSC and PEFC certified

Metsa Wood Academy

3. ENVIRONMENTAL | CERTIFICATION AND SUSTAINABILITY

3()&

FOREST STEWARDSHIP COUNCIL Formed in 1993, FSC is an international non-government organisation dedicated to promoting responsible management of the worlds forests

Metsa Wood Academy

PROGRAM FOR THE ENDORSEMENT OF FOREST CERTIFICATION Formed in 2000, PEFC is a non-profit non-governmental organisation and is considered the certification system of choice for small forest owners

CHAIN OF CUSTODY Chain of Custody certification is the way of tracking certified material from the forest to the end use. This shows via a paperwork trail from which forest the timber has been sent

4. TYPES OF TIMBER | HARDWOOD & SOFTWOOD

HARDWOOD AND SOFTWOOD We know that timber is cut from the trunk of trees. But from which trees does the timber we sell come from?

There are two categories of timber: HARDWOOD AND SOFTWOOD These terms may cause confusion with customers as some hardwoods have soft textures - balsa for example - and softwood does not mean the timber is not strong The difference between the categories relates to their botanical characteristics

Metsa Wood Academy

HARDWOOD

SOFTWOOD

Broadleaf trees that tend to lose their leaves during the winter

Conifers trees that have needles and cones

Also known as deciduous trees E.g. Oak, Cherry, Ash, Teak

Also known as coniferous trees E.g. Pine and Spruce

4. TYPES OF TIMBER | SOFTWOOD

REDWOOD (PINE)

WHITEWOOD (SPRUCE)

• Distinctive border between heartwood and sapwood.

• No distinction between heartwood and sapwood.

• Live knots reddish in colour.

• Knots are a similar colour to the surrounding wood and can be a dull grey colour.

• Contains more resin.

• Turns darker with age giving an orangey-red appearance.

• Is easy to machine.

• More oily to the touch.

• Easier to treat, accepts pressure treatment more readily.

REDWOOD (PINE)

Metsa Wood Academy

• Has a large proportion of pin knots.

• Has resin pockets.

• Much more pale in colour, turns to a silvery grey colour with age.

• Harder to treat, does not accept pressure treatment readily.

5. TIMBER GRADING | STRENGTH

Strength has less to do with looks and more to do with strength, i.e:

CE / UKCA

• Floor joists • Roof joists • Structural use

CE and UK CA marking is to ensure that construction products are safe by considering performance levels, ensuring the products are fit for purpose.

The stamp shown is a typical stamp that is on all strength graded timber

UK CA Marking will come into effect by the end of December 2024

The most important part of the stamp is the strength grade in the bottom right corner “C16” or “C24”

See www.gov.uk for more guidance Key timber products that have to be CE marked:

• Structural Timber (joists etc).

• Interior Timber Cladding.

• Exterior Timber Cladding.

• Timber Flooring.

• Non-structural Plywood.

6. COMMON TIMBER DEFECTS | DISTORTIONS

Spring Caused partly from the drying process but can also be caused due to stresses built up within the tree during its life

Bow Caused partly from the drying process but more often due to poor stacking

Twist Most frequently caused by spiral growth. All trees spiral during their growth, normally in their early growing life

Cup Almost always caused as part of the drying process

Metsa Wood Academy

6. COMMON TIMBER DEFECTS | VARIOUS Live knots are an integral part of the timber. The branch associated with this type of knot was still growing when the tree was felled

Blue stain - Fungi blue in colour.

Caused when the timber has been allowed to get wet. Blue fungi has no affect of the strength of the timber

Dead knots are an integral part of the timber. The branch associated with this type of knot was dead when the tree was felled.

Decay/Rot - Wood-eating fungi that thrive in conditions that promote growth. There are many different types of rot, the most common are wet and dry rot

Fallen knot - This term is used when a knot falls out of a piece of wood leaving a hole. This normally happens when a dead knot dries out and shrinks.

Pin hole borer - Neither the beetle or larvae feed on the timber, but is a convenient breeding habitat.

Unsightly for visual use, strength properties are unaffected

Wane - Bark on part of the board.

Caused by the machining process when cutting the board too close to the edge of the log.

Resin pockets - Normally seen as yellow-amber streaks that run along the grain. Most common in European whitewood. Sticky to the touch

Shake - Split along grain. Caused by natural stresses in the tree’s growth and during the drying process

Metsa Wood Academy

7. CONDITIONING TIMBER Timber is hygroscopic which means that the moisture content of the timber will vary in relation to the moisture in the air around it known as the relative humidity. This change in the moisture content will make the timber move as it swells and contracts accordingly.

High Moisture Environment Timber absorbs moisture and expands

Low Moisture Environment Timber dries out and contracts

Conditioning All timber that is used internally needs to be conditioned before use to ensure future problems with movement are avoided for approx 72 hours

Metsa Wood Academy

8. DOOR LININGS AND CASINGS Door linings and casings are used internally and inside openings to hang a door on. there are several different types.

Most have trenched or pre cut slots in the top rail.

Door Linings Have a loose door stop which is fitted to the lining and top rail

Door Casings Have an integral door stop pre machined into the lining and top rail

There are variations to the above such as special sizes for linings / casings that should be used in conjunction with CLS studwork walls and for fire protection, the latter also need an intumescent strip normally purchased separately to complete the fire protection of the lining or casing.

9. PRESSURE TREATED TIMBER

Timber is pressure treated with preservative so that it will last longer.

USE CLASS 1

USE CLASS 4

Roof timbers (dry)

Decking in ground contact

Once treated and dried:

First floor joists

Fence posts Garden products

• It is safe to use around the home • It is protected against insect attack and decay

USE CLASS 2

Garden products - water contact

Roof timbers (risk of wetting)

Always: • Cut in a well-ventilated room

Tiling battens Timber frame components except sole plates

USE CLASS SUMMARY

• Any cut ends or drilled holes should be treated

Battens for external cladding

• Wear protective clothing

Ground floor joists

1. INTERNAL, DRY 2. INTERNAL, RISK OF WETTING 3. OUTDOORS, TREATED, ABOVE GROUND

• Rough Sawn Treated range is treated wet so the level of penetration is limited limiting its life span

USE CLASS 3

• Incised posts are the harder to treat spruce.

Grooves are scribed into the surface to allow treatment to penetrate to a greater degree

External cladding

• Decking and constructional timbers are treated dry giving great levels of penetration for a longer life span

Decking out of ground contact

Fence panels Garden products Barge boards, fascias, soffits External joinery External doors

16. EXTRA INFORMATION | HOUSEKEEPING SIMPLE HOUSEKEEPING RULES It is well known that customers prefer to buy from neat and tidy, well stocked racks.

The following simple rules will ensure you maximise your sales: 1. When timber is sold as packs and single pieces ensure the single pieces are at the front of the rack and available.

No more than 1 pack should be opened for singles for each product 2. Face up regularly remove all plastic and strapping 3. Regularly turn outer layers of stock around to enable the product to dry out evenly to reduce the defects caused by uneven drying 4. Never leave any untreated timber or sheet materials outside 5. Always place timber on 2-3 equal bearers when storing for any length of time 6. Keep the database accurate so that your system does not allow any over stocks to occur 7.

Make sure product is in the correct bay and labelled correctly.

This will not only help customers but the staff who have to put the stock away

8. Sweep regularly between the aisles dirty looking displays suggest shoddy goods

Metsa Wood Academy

9. Forklift drivers watch your forks - timber damages easily 10. Keep racks free from obstructions. If a customer cannot get to the rack or even see the product it is unlikely they will buy it 11. Put timber under cover as soon as possible after delivery to avoid damage or getting it wet 12. When using line drawings please note that although sometimes shown on the plan, separate spigot arms should not be used to accommodate single pieces 13. Ensure the correct module is being used 14. Check that all lines that are on promotion or part of any deals have the relevant POS in place to promote the offer and that stock is available and well featured 15. When putting stock on the shelf make sure the label is the correct way up and facing the front of the rack There is a responsibility on store staff to ensure that timber products are properly looked after and maintained to ensure maximum sales and safety are achieved at all times.
