Preservation Treatment
Gargunnock Sawmill houses a treatment plant, in which we can permeate the cut wood for preservation against the elements using Koppers Celcure products.
Celcure® timber preservative is a waterborne, alkaline copper quaternary preservative system developed to provide long-term protection of timber exposed in interior and exterior applications. The Celcure® preservative system is based on the well-established effectiveness of copper combined with an organic quaternary compound and is applied to timber by pressure treatment.
What are the benefits for you, the customer, of preserving timber?
When exposed to certain conditions, in particular when the moisture content is allowed to rise above 24%, timber is susceptible to attack from fungal and insect attack. The life of properly treated timber is 5 to 10 times longer than untreated wood.
How Peter & W E Cramb treat timber
The method of application is in a sealed pressure vessel, to which a vacuum is applied to remove air from the wood cells.
Preservative is then forced under high pressure into the timber.
After the timber has absorbed the required amount of preservative, all excess fluid is removed from the cylinder and returned to the storage tank for re-use.
