If you are fitting Quick-Step Livyn in high heat areas or in direct sunlight please read below. Quick-Step Sun Heat Underlay may be the one to use.

When to use Sun Heat underlay

Main areas to consider:

• Conservatory Patio or bi fold doors where strong direct concentrated heat from the sun hits the floor • Roof lights where strong direct concentrated heat from the sun hits the floor

In the above situations it is likely that the floor temperature will exceed 45C

On wood-based sub floor, Ply, Wood, Particle Board etc with direct concentrated heat • sun heat must be used

On mineral based sub floor i.e. Concrete, Anhydrite, Magnesite etc with direct concentrated heat • Sun heat is optional, you can go direct to subfloor *no underlay* or with Livyn Basic Underlay

Unilin are unable to make this decision, it is the responsibility of estimator, retailer or installer to evaluate the location & environmental conditions. Eg. south facing room with BI fold or patio doors based on balance of probability the heat of the floor will exceed the 45c heat limit therefore Sun Heat is required.

You can not mix and match Sun heat to Basic as there is a 0.5mm thickness and 100 kPa difference, this would need to separated at the first doorway with a threshold or the same underlay utilised throughout.
