Why Use LOSP-Treated Roof Trusses?
Timber roof trusses should have some kind of treatment added to them. These treatments help wood repel pests and stay stronger for longer. If you aren't sure which treatment to choose, then take a look at a light organic solvent-borne preservative (LOSP). What are the benefits of installing trusses with an LOSP treatment?
Get Effective Pest and Fungal Control
Wood that has gone through an LOSP treatment gives you protection against pests and fungi. The timber is infused with special preservative chemicals in a solvent mix to start with. The solvent is then removed, leaving the preservatives lodged deep within the timber. Some LOSP treatments also include synthetic pyrethroids to give them better pest resistance in problem locations, say where termites are rife.
These preservatives protect your roof trusses against pest and fungal attacks. They work as both pesticides and fungicides. So, your trusses are less likely to be eaten or damaged by pests; you shouldn't have any fungal growth problems either inside the wood or on its surface.
This automatic control is important for roof trusses. You won't necessarily be able to inspect them once they are in place. So, you need them to be able to take care of themselves.
Reduce Swelling Problems
Some treated wood trusses need time to settle down after their initial treatments. For example, if you use a water-based treatment, then the timber typically swells and changes shape. It might need to go through one or more drying processes until it is ready to use. You can't guarantee that a piece of timber will come out exactly the same shape and size at the end of the treatment cycle.
LOSP treatments don't use water at all. So, the wood you start with will have the same dimensions and strength as the wood you work with. You don't have to wait for a load to dry before you can pick up your order.
Get Extra Water Repellence
Your roof trusses won't be exposed to the elements, so you don't have to worry too much about them getting wet in the rain. However, there might be times when they are exposed to water. For example, if you have a leak in your roof, then parts of a truss might get wet. If you don't spot this problem quickly, then the timber could start to rot.
You can buy LOSP-treated wood that has waxes added to it. These waxes give the wood useful water resistance. So, if a truss did get wet, it should be able to cope with the water.
