A Unitex Base Block is installed around the permitter at slab (base plate/stud/noggins) and at floor roof line to the first floor base plate (stud/noggin) below the base of the sheets, ensuring the system is completely sealed and no polystyrene is left uncoated preventing degradation. Under no circumstance should raw polystyrene be left exposed.
Does the Unitex Base Board System have a Bushfire Attack Level (BAL) Rating?
Yes, the standard Unitex Base Board System achieves BAL29 and a modified Unitex Base Board System achieves BAL40. Please contact your Unitex representative for further details.
What is the weight of the completed Unitex Base Board System per m2?

What is the R Value of the Unitex Base Board System?
The R value is a measure of the insulation value of a complete wall from internal plaster to exterior surface. Brick veneer is typically less than 0.8.
For Unitex Base Board 50mm, the R value is: 2.08 (including sisalation)
For Unitex Base Board 75mm, the R value is: 2.62 (including sisalation)
For Unitex Base Board 100mm, the R value is: 3.2 (including sisalation)
Why use pre-coated sheets instead of raw polystyrene?
There are several reasons:
1) Immediate protection from the elements. Raw polystyrene, if left un-coated will surface degrade and reduce adhesion of base coat renders, causing possible delamination of renders.
2) The first coat of render applied to polystyrene panels is crucial. This render must have superior adhesion and flexibility than standard renders for brickwork for instance. In the Unitex factory, EPS sheets are transformed into Unitex Base Board sheets by applying alkali resistant fibreglass mesh and a strongly adhering and flexible polymer modified cement coating with a consistent film build with a toothed profile. The special toothed profile makes it easy for the applicator to trowel on the base coat levelling render, (Uni-Dry Cote BBR 8.5 kg), at the recommended film build once the Unitex Base Board sheets have been fixed to the frame, ensuring that only the most flexible render on the market with the greatest adhesion has been applied on your project.
3) Raw polystyrene sheets should not be coated whilst wet as this prevents renders from adhering to the surface. This can cause major delays during winter months. Unitex Baseboard is manufactured inside under controlled conditions.
4) System warranty’s for your peace of mind, Unitex Baseboard is a risk free proven surface.
5) Speed. Unitex Baseboard saves time as the first coat of render is already completed.
