Vacsol®

Vacsol® 6118 is a water-based low pressure, industrially applied wood preservative from Arxada. It is both metal-free and VOC-free, and timber treated with Vacsol® 6118 can be reused or recycled at end of life.*

Providing an effective ‘envelope’ of long-term protection against fungal and insect attack, Vacsol® 6118 is the ideal choice for general building timbers and joinery components. Depending on end use application, it can provide a desired service life of up to 60 years. For more information on desired service life, please click here to download the Vacsol® 6118 Specifiers Guide.

Vacsol® 6118 has Biocidal Products Regulation (BPR) authorisation, passing all necessary risk assessments relating to the environment and to human and animal health.

Vacsol® 6118 End-Use Applications

Vacsol® 6118 is suitable for use in internal and external building applications above damp proof course (dpc) level. It can be used to treat timbers in Use Class 1, 2 and 3.1 (coated) such as:

  • General internal building timbers;
  • Timber frame material;
  • Roofing components;
  • Floor components;
  • Window frames (coated).

Exterior joinery, such as window frames, must be subsequently protected with an appropriate and maintained surface coating.

Use Class Information

Use Classes are defined by European Standards, providing a guide to the risk of decay and insect attack to timber components, depending upon their end use. The higher the Use Class, the higher the level of preservative protection required.

Vacsol® 6118 is suitable for Use Class 1, 2 and 3.1 (coated) timbers. Timber treated with Vacsol® 6118 must only be used above the damp proof course level and/ or above ground contact. Exterior joinery/woodwork must be subsequently protected with an appropriate and maintained surface coating.

Use Class Summary

1      Internal, dry. For example: floor joists
2      Internal, risk of wetting. For example: sole plates, tiling battens
3.1   Outdoors, coated above ground. For example: window frames
