Why is Taylormade Timber offering a guarantee now and what does it cover?

 

There have been recent reports within the UK fencing industry of failures of preservative pre-treated ground contact fence posts due to rot. With the timber processing procedures and preservative treatment technologies we employ, we are totally confident that all our fencing timbers, including ground contact fence posts, will do the job they are designed to do. Taylormade Timber has introduced a 15 year guarantee on all our Good Wood range of kiln dried, redwood preservative treated fencing timbers to affirm this confidence for all our customers requiring such a reassurance.

The guarantee covers all our Good Wood preservative treated fencing timbers for both in and out of ground applications against the threat of wood decay and insect attack for 15 years. The guarantee is for the cost of resupply, by Taylormade Timber, of a component that is proven to have failed as a result of fungal decay or insect attack. It does not cover the costs of removal or reinstatement of such components or consequential costs or loss due to failure of the component.

We also offer our Premium range of fencing timers. These timbers are manufactured from mixed conifer species and are not kiln dried prior to treatment, offering a lower cost option that does not carry a warranty. They will have an expected service life of 5-10 years.

 
 


If you are now offering a guarantee does this mean that previous treated timbers supplied by Taylormade Timber are not to specification?

 
 

In introducing the new guarantee we have changed very little in our production procedures. We are still utilising the most effective and proven wood preservative within our treatments, Tanalith E, which underlies our confidence in the longevity of our fencing products. We are still using the best quality timbers and making sure they are prepared for manufacture and preservative treatment in the best way. We are still manufacturing and processing all our timbers through our own quality controlled production procedures. We are now using only redwood species for our GOOD WOOD ground contact fence posts, but we are still totally confident that any whitewood species fence posts we have supplied in the past will continue to do their job.

 
 


How can Taylormade Timber be offering a 15 year guarantee on such a relatively new preservative?

 
 

Tanalith E wood preservative was first developed by Arch Timber Protection in the late 1980s as an effective alternative to traditional CCA wood preservatives. It is a unique formulation product that has now been in commercial use around the world since the early 1990s.

 
 

Although Taylormade Timber only started using Tanalith E in the early 2000s we have every confidence in its protection properties for our timbers. Not only is there two decades of proven commercial use in a wide range of applications and markets, Tanalith E has also been extensively tested in independent field trials all over the world in some of the most aggressive end use conditions for timber. In these tests Tanalith E has proved superior to other new generation wood preservatives.

 
 


There were never any perceived problems on fence posts when we had CCA preservatives. Why can we not have CCA treated fence posts?

 
 

Even during the days of CCA (chromated copper arsenate) wood preseervatives there were some failures reported. It is not only the performance credentials of the wood preservative that produces high performance treated timber, but also other factors such as which species of timber are used, how well the timber is prepared ready for treatment and how professionally the treatment is carried out.

CCA wood preservatives were safely used for many years to provide an effective protection for timber. However, in the early 2000s new legislation from the EU severely restricted the use of CCA products to the treatment of timbers used in 'industrial applications'.

 
 

This restriction means that fencing timbers can no longer be treated with CCA preservative. In Tanalith E we believe we are using the most effective 'new generation' wood preservative, particularly for ground contact timbers.

 
 


What has caused the fence post failures that have been reported?

 
 

From independent investigations that have been made the failures are due to a combination of reasons.

 
 

Firstly, the preservative products used to treat the failed posts may have been used at an inappropriate solution strength. Also the failed posts had a higher than ideal moisture content when preservative treated which makes the penetration of the preservative into the timber so much more difficult.At Taylormade Timber we know that in Tanalith E we have the very preservative to do the job of protecting our fence posts and fencing timbers and we ensure that both the pre-treatment moisture content and the preservative solution strength are at the correct levels.

 
 

We are also now using only redwood timbers for our Good Wood fence posts. These species can be easier to pressure pre-treat than whitewood timbers.

 
 

When installing fencing timbers are there any special operational procedures that should be undertaken?

 
 

Yes. To maintain the integrity of the preservative protection, if any cuts, notches or drillings are made to the fencing timbers, the exposed surfaces should be liberally brushed with an end grain preservative, such as Ensele, to the manufacturer's instructions.

 
 

Fence posts must not be pointed after treatment and the shortening of fence posts should be avoided. If posts are shortened, the cut end must never be used in ground contact.

 
 

Any fence posts that are further processed, eg planed, must be returned to Taylormade Timber for re-treatment.
