Micronised Timber Treatment Process

Long Lasting Timber
To help ensure the long term performance of our softwood Brookclad cladding timbers, they can be preservative treated with a water based Koppers Microshades Wood Preservative to protect them against the threat of decay and insect attack
Brookridge Timbers uses an industrial high pressure impregnation process to force the preservative into the wood structure.  This protection is in the cladding timbers for good and no further treatment is required. Brookclad timber cladding preservative treated in this way can come with a 30 year warranty against decay and insect attack when used out of ground contact if required.  Please contact us for more details
The resulting cladding timbers are a rich brown colour achieved using a pigment with UV inhibitors.  This means that the Brookclad timber cladding treated with the Microshades process will hold its colour for a longer period than other similar treatments reducing the rate of weathering.

Step One

Timber loaded into treatment vessel. Initial vacuum applied and the timber cells are evacuated of air. Vacuum held.

Step Two

Cylinder flooded under vacuum with Koppers wood preservative.

Step Three

Hydraulic pressure applied, forcing the preservative deep into the structure of the timber.

Step Four

Final vacuum extracts excess preservative solution, which is pumped back to storage.

Step Five

Low pressure inside timber draws in surface solution when vented to atmosphere. Treated timber is left to dry.
