SANBOARD - Thermal Insulation (R-Values) By Thickness:

SANBOARD Polystyrene Ceilings are thermal insulating ceilings and the amount of insulation they provide is determined by the thickness of the ceiling. The thicker the boards the more insulation they provide.

In insulation terms, the insulation value is called the Thermal R-Value and the actual insulation values can be seen below:

Thickness (mm) Thermal R-Value
30mm 1.000
40mm 1.330
50mm 1.670

Calculating what you need?

Step 1: Choose the right thickness:

The thicker the boards, the more insulation you get and this is important when it comes to heating or cooling the room in the cold and hot months of the year.

Step 2: Calculate the board lengths and number of boards required:

  • We supply these ceiling boards in lengths from 1800mm (1.8m) to 8000mm (8m)
  • They are all 600m wide.
  • The 100mm V-grooves run along the board lengths and when these boards are joined together, then a new V-groove is formed to create a continuous pattern.
  • Depending on the room design, choose which way you want the pattern to go. Then measure this length from wall to wall to give you the lengths of the boards required.
  • Each board is 600m (0.6m) wide, so if you divide the total width of the room in meters by 0.6 this will give you the number of boards you will need of that length.

Step 3: The brandering lattice support structure:

  • Like normal ceilings, in normal nail-up applications you are going to need a brandering support lattice to attach the ceiling to, clips and glue.
  • The maximum distance between the brandering lattice support structure should not be more than 700mm center to center.
  • We don't supply this structure.

Step 4: Clips & Glue Requirements

  • You are going to need clips and glue to attach these ceilings properly. (see below)
  • Work on 3 clips per m2 of ceiling
  • Choose the right glue tub sizes base on their spread rates given in this product detail. (see below)
  • The clips and glue you will find below.

Step 5: You are now ready to order online!

  1. Simply select the closes national depot to you.
  2. Add the board thickness and lengths required to your order cart.
  3. Order online for delivery or collection.
  4. Simple as that!
