Hi, my fellow renovation buddies! It’s Naomi Findlay here.
Did you know I have a renovation course? You can check it out here!
Resident chippy Rowan and I are here today to talk about all things timber and timber treatments!
As you know, timber is used in most of our renovating and construction around this country. But the Australian climate is pretty harsh so we need to be conscious of what timbers we use in different settings.
There are a number of classes of timber to determine durability, here is a cheat sheet to know what each means:
- H Level = Hazzard Level: refers to the level of termite treatment and fungal resistance.
- F Class: refers to the strength of the timber.
- MGP = Machine Grade Pine: refers to the bendiness and elasticity of a piece of timber.
Today we’re going to address the Hazzard Class. The Hazzard Class system extends from H1 to H6:
- H1 and H2 should be used for internal use only.
- H3 can be used externally, however, it should have no contact with the ground.
- H4 is great for external use. H4 can have contact with moisture, however, it should have the opportunity to dry.
