1. HOW IS EXIN FIXED? (See Technical Data Manual)
By screw fixing board back to frame.

2. WHAT IS THE FIRE RATING OF EXIN?
EXIN comprises of an EPS core that is made of self-extinguishing expanded polystyrene. (It self-extinguishes when the source of the flame is removed.)

3. WHAT IS THE NOISE/SOUND RESISTANCE OF THE BOARD?
No official tests have been conducted by RMAX, but with the use of other sound-inhibiting materials a wall made up of 40mm EXIN can obtain a rating of 40 STC. (See your distributor for further details)

4. WHAT THICKNESS DO YOU RECOMMEND?
In Australia, due to the extreme variations in temperature we recommend 75mm EXIN. It has excellent thermal insulating value and a depth of reveal at windows that enhances its architectural appearance.

5. HOW DOES IT COMPARE IN PRICE TO BRICKS OR FIBER CEMENT BOARD?
EXIN saves time in erection costs due to the ease of installation, but we recommend that you discuss this with your local distributor, as transport and labour costs have a great bearing on the overall figures.

6. WHAT THERMAL RATING CAN I EXPECT?
See Technical Data Manual. 40mm EXIN with 10mm plasterboard on a 90mm stud will generate 1.5 R-value.

7. WHAT HAPPENS IF SOMEONE HITS IT WITH A BALL OR A MOWER KICKS STONES AGAINST THE WALL?
EXIN has a high impact resistant! The material may dent, depending on the velocity of the projectile, but the dent is very easily patched.

8. WHO STOCKS THE PRODUCT, CAN I PURCHASE DIRECT FROM RMAX?
See Distributor listing RMAX does not sell direct to the public.

9. WHO CAN INSTALL THE PRODUCT?
Best success has been through carpenters or qualified tradesman.
