There are two options for resisting termite action as per AS1720, AS1684 and AS3660:
- Resistant materials as 'primary building elements'
- Barrier systems
Both T2 Blue and T2 Red treated timber framing come with a 25 year guarantee against structural damage as a result of termite attack. However, T2 Blue framing is designed for protection against termites found in areas south of the Tropic of Capricorn, while T2 Red is designed for protection against termites found north of the Tropic of Capricorn. The Tropic of Capricorn is the circle marking the latitude 23.5 degrees south, where the sun is directly overhead at noon on December 21, the beginning of winter in the northern hemisphere. In Queensland, the Tropic of Capricorn runs through the Rockhampton city area.
