WHAT WOOD SHOULD I USE FOR MY GARDEN FENCE ?

SOFTWOOD TIMBER WITHIN THE UK IS AVAILABLE MAINLY IN WHITEWOOD (NORWAY SPRUCE) AND REDWOOD (SCOTS PINE)

AT JON WALKER TIMBER WE RECOMMEND AND USE REDOOD PINE FOR GROUND CONTACT , KILN DRIED TO MAXIMUM 28% MOISTURE CONTENT, FOR FENCING TIMBER POSTS .

JOINERY REDWOOD IS KILN DRIED AS LOW AS 12% MOISTURE CONTENT .

WHITE WOOD SPRUCE IS USED MAINLY AT JONWALKER TIMBER FOR BOARDS, FEATHER EDGE ,  RAILS  AND  PALES , REASON BEING IT IS RELATIVELY FREE FROM KNOTS .

KNOTS TEND TO BE PREVALENT IN REDWOOD AND FALL OUT CREATING PEEP HOLES – NOT IDEAL FOR A PRIVACY FENCING – SO HENCE REDOOD FOR POSTS.

REDWOOD PINE KILN DRIED AND WHITEWOOD SPRUCE ARE CHECKED PRIOR TO TANALISING PRESSURE TREATMENT WITH A MOISTURE METER TO MAKE SURE WE CAN IMPREGNATE THE TIMBER UNDER PRESSURE TO THE  RETENTION KG PER METER CUBED .

UNFORTUNATELY IN THE MARKET PLACE THERE IS VAST QUANTITIES OF TIMBER THAT IS NOT CORRECTLY KILN DRIED TO THE  RIGHT LEVEL OF MOISTURE .

THEREFORE THE TIMBER CANNOT ABSORB UNDER PRESSURE THE RIGHT LEVEL OF TREATMENT

ALSO BECAUSE TIMBER IS COMPETITIVE ON PRICE , BUYING THE CHEAPEST IN REAL TERMS WILL VERY OFTEN WORK OUT TO BE THE MOST EXPENSIVE.

AND ON CARBON FOOTPRINT  – A POOR TREATMENT MEANS TIMBER ROTS QUICKLY AND MORE TREES HAVE TO BE CUT DOWN .

 

SO MANY COMPANIES IN THE UK DON’T CARE ABOUT THIS AND THINK THE CUSTOMER THEN HAS TO RETURN TO THE MARKET PLACE EARLIER TO RE-PURCHASE THE SAME TIMBER .

WITHIN A 25 YEAR PERIOD THE SAME TIMBER COULD BE REPLACED 3 OR 4 TIMES .- 

HIGH MOISTURE CONTENT AND LOW CHEMICAL STRENGTH  WILL CAUSE THE TIMBER TO ROT IN 3 – 5 YEARS .

ON MANY INSTALLATIONS WE HAVE REPLACED TIMBER BECAUSE OTHER COMPANIES HAVE SUPPLIED AND INSTALLED WHITEWOOD SPRUCE FOR GROUND CONTACT .- THIS IS UNACCETABLE PRACTICE.

AT JON WALKER TIMBER WE USE  A HEAVY DUTY TREATMENT  BRANDED JON WALKER TIMBER “GOLD” TREATMENT .

WE, AT JON WALKER TIMBER  TANALISE PRESSURE TREAT TO RETENTION OF CHEMICAL IMPREGNATED INTO THE TIMBER    – NOT JUST A CYCLE ,  IT IS SO SO IMPORTANT TO MAKE ABSOLUTELY SURE THE CORRECT LEVEL OF CHEMICAL  IS RETAINED WITHIN THE TANALISING PRESSURE TREATMENT PROCESS.

 

THE PROCESS WE USE AT JON WALKER TIMBER ENSURES TIMBER WILL LAST THE TERM OF 25 YEARS  – SO WE ARE NOT AFRAID TO PUT OUR NAME ON A GOLD BRANDED TIMBER PRODUCT THAT WILL LAST ,

WE RECOMMEND AND TO QUALIFY FOR OUR 25 YEAR GOLD WARRANTY , INSTALLING REDWOOD POSTS, HEAVY DUTY TANALISING, WITH POSTSAVER SLEEVES .

AT GROUND LEVEL – DEW POINT LEVEL AND WET GROUND , PARTICULARLY THE CANOPY AT EDGE OF FOREST OR UNDER DECKING WHERE THE TIMBER NEVER DRIES OUT , THE BITUMEN PLASTIC POSTSAVER SLEEVE WILL RESIST THE PENATRATION OF WATER   AND HELP THE TIMBER LAST TO ITS WARRANTY TERM OF 25 YEARS

TESTING AT LONZA LABORITORIES

 – OVER A TWO YEAR PERIOD WE HAVE SENT OUR TIMBERS AFTER TREATMENT AND IS NOW ONGOING  – TESTS HAVE PROOVED THAT  JON WALKER TIMBER TREATS TIMBER TO RETENTION AT 29.4KG PER M3 . THIS IS EQUIVALENT , AND VERY OFTEN IN EXCESSS TO DEPARTMENT OF TRANSPORT SPECIFICATION.

WE ALSO SEND OUR CHEMICAL FOR TESTING ON A MONTHLY BASIS TO MAKE SURE CONCENTRATES OF CHEMICAL ARE MIXED CORRECTLY .

TIMBER POST STOCK CODES  AS PER OUR WEBSITE  SAW002A ,SAW004CC ,SAW003 , SAW009AC1SAW009AI,SAW009AZ4    WHETHER IT BE GATE POSTS , FENCING POSTS , POST AND RAIL , POSTS FOR GARDEN PANELS AND HURDLES

ROUND TIMBERS REFER STOCK CODES MTP001 TO MTP028

ASK FOR JON WALKER TIMBER GOLD LABEL TREATMENT WITH 25 YEAR WARRANTY.

COLOURS CAN BE TANALISED GREEN OR TANATONE BROWN .,

 

WHEN REQUESTING BOARDS , RAILS , FEATHER EDGE , TRELLIS , GARDEN FENCE PANELS , BATTENS , CAPPINGS MAKE SURE THESE ARE TREATED TO A MINIMUM OF HAZARD CLASS 4 TREATMENT

15 YEARS AND CHEMICAL RETAINED T 17.5KG PER M3  – NOTHING LESS WILL DO.

SO ASK FOR JON WALKER TIMBER GREEN LABEL 15 YEAR SERVICE LIFE .

AT JON WALKER TIMBER WE HAVE BEEN TANALISING PRESSURE TREATING TIMBER FOR 30 YEARS .

WHY 25 YEAR WARRANTY GOLD TREATMENT AND WHY 15 YEAR GREEN LABEL TREATMENT ???

30 YEARS AGO WE USED TO TREAT WITH CHEMICAL MAKE UP WITH COPPPER CHROME ARSENIC .

THIS WAS TANALISED PRESSURE TREATED TO 5.3KG RETENTION PER M3 .FOR A 15 YEAR HAZARD CLASS 4 TREATMENT TRADE COST WAS ABOUT £25 PER M3 .

TODAY THE HEALTH AND SAFETY EXECUTIVE HAVE BANNED THE USE OF ARSENIC IN TANALISING CHEMICAL .- THIS WAS ONE OF THE MAIN TIMBER PRESERVATIVES .

TIMBER TREATERS ARE STILL TRYING TO TREAT TIMBER AT A PRICE OF £16 – £25 M3 BUT IN REALITY THIS DOESN’T DOSE THE TIMBER WITH ENOUGH CHEMICAL

HAZARD CLASS 3  REQUIRES 8.5KG OF CHEMICAL RETENTION PERM3 OF TIMBER

HAZARD CLASS 4  15 YEAR SERVICE LIFE REQUIRES 17.5KG RETENTION PER M3  OF TIMBER.

JON WALKER TIMBER GREEN LABEL TREATMMENT

HAZARD CLASS 4 30YEAR SERVICE LIFE – 25 YEAR WARRANTY REQUIRES 29.4KG RETENTION PERM3 OF TIMBER

JON WALKER TIMBER GOLD TREATMENT 

THESE NEW TIMBER PRESERVATIVES USE BIOCIDES , BARROMINE, AND AZALES . BUT WE FEEL AT JON WALKER TIMBER THESE ARE NOT AS STRONG AS THE OLD COPPER CHROME ARSENIC PRESERVATIVE. AND THEREFORE REQUIRES EXTRA DOSING .

SOME TIMBER TREATERS RELY ON ADVICE THAT IF THE TIMBER IS 50% SAPWOOD THE CHEMICAL RETENTION CAN BE REDUCED BY 50%.

AT JON WALKER TIMBER WE DON’T RELY ON THIS 50% REDUCTION  AND FEEL IT IS BETTER TO OVERTREAT THE TIMBER AND MAKE TOTALLY SURE AND GIVE THE TIMBER ITS BEST CHANCE OF LASTING THE TERM BY OVERTREATING .

WHILST OUR PRICE REFLECTS THIS , ITS NOT CHEAP TO WORK TO A HIGHER SPECIFICATION

BUT WE WOULD RATHER SELL A BETTER QUALITY TREATED POST THATI  JON WALKER TIMBER CAN PUT THEIR NAME TOO , OUR EMPLOYEES FEEL THE SAME . SO WE HAVE ADOPTED THE LONGER LASTING , HIGHER DOSING GOLD LABEL , 25 YEAR WARRANTY TREATMENT

 ALSO BE WISE THAT IN THE UK WE TANALISE PRESSURE TREAT TIMBE TO 12 BAR

IN EUROPE THE REGULATIONS ARE DIFFERENT AND ONLY TANALISE PRESSURE TREAT TO 8 BAR

SO BE CAREFUL ON PURCHASEING IMPORTED TIMBER AND ASK HOW THIS HAS BEEN TREATED .

BE SURE TO ASK FOR JON WALKER TIMBER GOLD LABEL TANALISED PRESSURE TREATED TIMBER.
