Introduction
The BS EN 13501-1 classification system is used to assess the fire safety of various materials. This system determines how quickly a material will ignite and emit heat and how quickly it will burn and emit smoke.
Wood can be classified from B to F by analysing test data. To achieve a Euroclass B standard, fire retardant products can be applied to wood that is normally classified as D to F.
How to treat raw wood with intumescent fire retardant to achieve Euroclass B
Step 1: Choose the right intumescent fire retardant for the type of wood you are treating.
Step 2: Measure the wood and determine the amount of intumescent fire retardant needed.
Step 3: Apply the intumescent fire retardant on the wood surface according to the manufacturer's instructions.
Step 4: Allow for the intumescent fire retardant to thoroughly dry according to manufacturer instructions.
Step 5: Use a top coat to protect the intumescent fire retardant. One or two coats should be enough depending on where the wood will be used.
Step 6: Monitor the wood periodically for any signs of wear or damage.
Painted or varnished wood treatment to achieve Euroclass B
To properly treat painted or varnished wood, apply an adhesion primer before following the same steps as if you were treating raw wood.
Case Study Worth School Euroclass B
Contractors renovating part of the school got in touch with us to treat larch plywood to Class B standards. They told us the dimensions of the wood panels, and we figured out the total square metres of wood.
We calculated the quantities of intumescent fire retardant and top coat needed by analysing the data. By doing this, we were able to calculate an estimate for the materials and labour expenses.
After the quote was accepted, a date was set to apply the fire retardant. It is important to consider that the humidity and temperature must be at optimum levels for intumescent coatings to be applied, limiting the months when they can be used.
After the fire retardant and top coats were applied, a BS EN 13501-1 Class B certificate was issued.
