Preservatives Warranty
Our windows are treated with Sikkens Cetol WV 882 Preservative.
This is a water borne, Boron based preservative, for which Sikkens provide us with a guarantee. With the correct maintenance Cetol WV 882 will give the timber 30 years protection against decay.
The effectiveness of this treatment is dependent on keeping the coating intact throughout the lifespan of the window. The timber must not have a moisture content consistently above 18%.
Warranty covers the timber against:
- Brown Rot
- White Rot
It does not guarantee against:
- Insect attack such as termites.
Once the joinery is supplied, the main conditions for the warranty to remain valid are that:
- The windows are installed promptly in accordance with our instructions. Please ensure that windows are not left on the ground prior to installation. They must be stored above the ground.
- Should the coating become damaged when the windows are installed the coating is promptly repaired in accordance with our remedial coating instructions, please contact us for details.
- Only coatings recommended by us are applied to the joinery.
- The correct coating maintenance schedule is followed.
- The warranty registration form is returned to us within eight weeks of purchase.
Please Note: Only joinery that has received a coating with a minimum dry film thickness of 60 micrometres will be protected by the preservative. All joinery from George Barnsdale and Sons has received a minimum of 100 micrometres dry film of coating.
