Quality timber treatment: the key to success!

Timber used outdoors , exposed to the elements or in contact with the earth or those used in water need in -depth protection  that  a vacuum pressure process can reliably provide. 

Essential criteria

High-quality treated timber must fulfill two basic criteria for a long service life:

The required loading and an adequate penetration of the timber with the wood preservative. Both, the preservative's required retention level and the required penetration depth depend on the final application of the treated timber, the wood species and the wood preservative. Depending on the application of the timber - expressed in use classes (UC) - the exposure to fungi and insects differs. It is pretty simple: The higher the use class the higher the required penetration of the timber.

UC1:  internal, dry (for example upper floor joists)

UC 2: internal, wetting possible, no direct weathering (for example roofing and tile battens timber frames)

UC 3 : external, direct weathering, no ground contact (for example fence rails, decking boards, fence panels, external joinery, cladding) 

UC 4 : external,  permanent ground contact, severe weathering and attack of fungi (for example fence/gate posts and all timber in ground contact like decking joists and sleepers)

High-quality wood preservatives are complex chemical formulations of different active ingredients, co-biocides and additives in order to achieve the highest performance. The most crucial performance properties are a high efficacy against wood destroying fungi and insects as well as the preservative's ability to penetrate the timber.

The penetration properties of the preservative are the key to achieve a high quality treatment. However, different timber species have got different penetration properties. Some wood species like spruce or douglas fir are very difficult to penetrate, while others like pine are much easier to penetrate.

High -quality treatment and state of the art quality control is the most promising way to increase teh trust in treated timber. Wolman products, which  have undergone extensive ecological testing, are guaranteed to provide wood with reliable and long- lasting protection.  

What is Wolmanit® CX?

Wolmanit® CX is a liquid wood preservative for use in industrial pressure-impregnation plants. it is used extensively in mainland Europe and the UK to protect timber from all forms of biological decay.  Wolmanit® CX will be stable over a long storage time under different temperature conditions to ensure a proper, homogeneous distribution of the active ingredients in the treatment solution and finally in the timber. The toxicological and eco-toxicologial foot-print are positive to position timber treated with Wolmanit® CX as sustainable and eco-friendly building material.

Wolmanit® CX has....

  • Superior independent penetration data
  • A unique biocide and even distribution of chemical throughout the treated zone
  • Large market share in those countries with independent quality schemes

What is special about Wolmanit® CX treated wood?

Wolman has been at the forefront of timber treatment technologies for a century. Wolman pioneered the development of environmentally advanced, low-hazard preservatives that retain superb performance in service. Wolman is the 'original in wood preservation'.

Where can I use Wolmanit® CX treated wood?

Wolmanit® CX treated wood is designed for garden timbers and fencing as well as interior and exterior construction purposes. Wolmanit® CX treated wood should not normally be used in permanent saltwater contact and freshwater applications should first be discussed with Wolman.

Which glues and fixings can I use?

Most standard wood glues will bond Wolmanit® CX treated wood but specific advice can be sought from Wolman. Wolmanit® CX treated wood is not corrosive to metal fixing but care should be taken to use appropriate products. Hot-dipped or stainless fixings should be used for outdoor applications to protect from atmospheric corrosion.

Does it conform to current European Standards?

Wolmanit® CX conforms to the service expectations set down in BS EN 599. The UK interpretation of the document is BS 8417. Wolmanit® CX is also included in the wood protection Association Manual.

How do I handle the treated wood safely?

Wolmanit® CX treated timber is not classed as hazardous. Once dry it can be handled safely and is suitable for children's playground equipment. As is the case with any wood, treated or not, goggles should be worn when rip-sawing and gloves will protect from splinters.

 

We stand by our timber treatment . . .

As a specialist in Fencing, Garden Products, Gates, Sheds etc., we have unrivalled experience in manufacturing and supplying products that are used in ground contact and wet conditions. Since the introduction of Walman in 2013, we are confident our products will have a 10+ year service life as we produce all our ground contact material (Posts, Gravel Boards, Sleepers, Decking, Bollards) using ‘Wolmanit® CX’ high pressure treatment to Class 4 (UC4) - as specified by BASF group, the world leaders in timber treatment technology.

 

Fountain Timber Products has always been an environmentally-minded organisation. We care about timber and take great pride in producing high quality products while minimising the impact production has on the environment.

We operate to ISO 14001, a certified and strict Environmental Management Standard.


When you buy timber for direct soil contact . . . Make sure it is treated to Use Class 4

Steps taken by us for treating ground contact timber to UC4

  1. Timber is dried to 28% moisture content or below in our own drying kiln (With the exception of Spruce that more readily accepts treatment at over 30% moisture)
  2. We treat timber in like for like batches (ie Pine with Pine, Douglas Fir with Douglas Fir, Larch with Larch and Spruce with Spruce)
  3. We monitor, measure and record all treatment cycles to ensure we outperform the manufacturers high treatment standards
  4. We allow it to dry and deliver when ready.  

 

With all these steps we can be confident in offering our customers a 10+ year service life protection against rot or insect attack. The only things that will void this protection are:

Cutting

(unless cut ends are liberally treated with a good wood preservative. ie. Womanit® C&T or Ensele®)

Notching

(unless notches are liberally treated with a good wood preservative. ie. Womanit® C&T or Ensele®)

Damaging

(ie excessive damage or splitting of pointed stake during installation)

Equalising/Planing

(without returning for re-treatment)

The shortening of posts or stakes should be avoided wherever possible. The cut end SHOULD NEVER be placed in the ground

FREE REPLACMENT UNDERTAKING

Fountain Timber treatment to Use Class 4 standard is for use in ground contact. Since the introduction of Walman in 2013 all UC4 products are supplied with a service life of exceeding 10 years protected against any failure caused by rot or insect attack. Any UC4 product supplied by Fountain Timber which fails due to either fungal decay or insect attack, during this 10 year period will be replaced FREE OF CHARGE subject to the following conditions:- The timber must be used for the supplied purpose and not placed in any abnormal conditions not highlighted to Fountain Timber Products at the time of purchase or alternatively removed from their original position and re-used in differing conditions. If the product is cut, notched or drilled it is essential the cut ends be liberally treated with Womanit® C&T or Ensele® end wood grain preservative. Fence post should not be pointed after treatment. The shortening of fence posts should be avoided wherever possible. Under no circumstances should a cut end be placed in the ground. If setting posts in concrete, suitable drainage/run off must be applied, allowing water to flow freely away from post. Proof of purchase must be supplied with any claim; this can be by way of receipt, invoice number or delivery note number for the products in question. We will require the return of samples (WHOLE POST) for any failed product to identify the cause of failure and to test the quality and penetration of the treatment This undertaking will cover the cost or replacement of the product as supplied by Fountain Timber Products.
