Roof Trusses Treatment


At Minera we are extremely aware of the importance of ensuring that timber is properly treated to ensure it will stand the test of time, preserving it against fungal decay and insect attack.

We therefore offer an onsite treatment facility to ensure only the best possible preservatives are applied to our timber. We utilise a product called Protim Clearchoice to ensure full protection against wood boring insects and fungal decay throughout the service life of the project for internal and external timbers in above ground applications. Our facility is used to treat our manufactured Trusses and our Engineered Floor Joists (Open Metal Web). However we also provide a treatment service to local joinery companies.
