Timber Fire Protection

Timber Fire Protection AITHON PV33

Keep constructions most versatile and reliable material protected under heat.

Structural fire safety is achieved either by what is called ‘passive protection’ e.g. fire-resistant lining boards and/or ‘active protection’ e.g. smoke ventilation, alarm systems and sprinklers.

For the structural engineer, the material choice within the structural solution will influence the passive and active fire protection strategy.

There are three ways to protect the timber from fire:

Fire Retardant Varnish

If you want your wood to have that varnished look or you have timber to protect that has already been stained or varnished meaning you can’t use a fire retardant treatment then a fire retardant varnish is an option for you.

This will delay the inflammation of your wood in a fire, protecting the surface.

Fire Retardant Paint

When painting over old paint on walls and ceilings, you need to use a basecoat first to upgrade the surface to be fire retardant. This applies for any previously painted interior timber too. You can get fantastic paints which can be painted straight on to the surface and either left as a finish or overpainted with normal decorative paints.

Fire Retardant Treatment

Bare interior and exterior timber can be protected with fire retardant fluids that soak into the surface to leave your timber looking natural whilst protecting it from fire damage. You can soak the surface and achieve a surface that looks untreated that doesn’t have any kind of glaze or residue like varnish. You’ll not be able to know the wood has been treated, and you can even use a wood stain or varnish afterwards to decorate if you wish! This format is low odour, water-based and versatile.

That’s the three main ways to protect your timber surfaces around your property. All the above products and systems achieve varying degrees of Surface Spread of Flame protection (BS Class 1, Class 0, EN Class B, etc.). If you require systems to achieve 30 or 60-minute protection, please contact our team on 0330 094 9099 or hello@atolconstruction.co.uk.

If you don’t protect timber, in an unfortunate event like a fire, you’ll find it spreads much quicker. Take every precaution you can.

Timber Fire Resistance

Fire resistance is typically presented as a duration of time.

The fire resistance of an element (wall, floor or roof) is a measure of its ability to withstand the effects of fire in one or more ways as follows

Structural ‘loadbearing capacity’ to maintain the design loads under fire (R)

‘Integrity’ of the element which is the resistance to fire penetration (E)

‘Insulation’ which is the resistance to the transfer of heat to the face of the element remote for the fire (I)

Aithon PV33 is the only varnish which grants:

Aithon PV33 at ambient temperature is a perfectly transparent varnish, with a warm looking wax finish to exploit the timber natural beauty.

In a fire, it reacts generating a thick layer of carbon char able to withstand heat above 1000°C, and protect timber structures up to 60 minutes.

Reduces the speed of carbonisation up to 0,33 mm/min (unprotected timber: 0,8 mm/min according to Eurocode 5 – Timber Structures)

During the reaction, a thin carbon char layer is created reducing the fires ability to spread quickly.
