Progress at Graven Hill Primary School


We are pleased to report that great progress is being made on the external timber panels at Graven Hill Primary School. The team has been working hard to ensure that the wooden cladding system is installed to the highest standard, and we are delighted with the results so far.

We are using thermowood PEFC (Programme for the Endorsement of Forest Certification) certified timber. PEFC certification ensures that the timber has been responsibly sourced from well-managed forests and is therefore environmentally and socially sustainable. In addition to its sustainable sourcing, thermowood has a number of inherent properties that make it an ideal material for use in external applications.

Thermowood is a type of softwood that has been thermally modified. This process involves heating the wood to high temperatures, which changes its chemical structure and makes it more stable and resistant to moisture, rot, and insect damage. Thermowood is also less susceptible to warping and splitting than untreated wood, making it an ideal species for use in exterior timber cladding systems.

By using secret fixings in our timber slat panels, which are hidden from view, the surface of the timber remains intact, preventing moisture ingress and promoting better weathering. When timber is penetrated by screws or nails, it creates a pathway for moisture to enter, which can lead to rot and decay over time. This would be particularly problematic in external applications where the timber is exposed to the elements and moisture levels can fluctuate dramatically.

In addition to the practical advantages of secret fixings, there are also aesthetic benefits to consider. By avoiding surface penetrations in the timber cladding panel, the timber retains its natural appearance, free from unsightly screwheads.
