Silica insulation bricks are commonly found in furnaces, kilns, incinerators and other places where you can find high temperatures.

Kilns and furnaces are constantly being exposed to high heat and this makes it imperative that the bricks are going to be strong and heat resistant. They need to heat and cool evenly so you can avoid thermal shock which can cause them to crack if they are heated and cooled too quickly.
Buying high quality bricks from rsRefractoryfirebrick.com is going to save your company money in the long run because the bricks are not going to crack as often which means you need to worry less about replacing them. Having to take your furnaces apart to replace the bricks on a regular basis can get expensive and you want to save money whenever you can which is why you should use silica bricks.
Silica bricks are strong and they are affordable. They can last through multiple heating and cooling cycles without cracking and will give you plenty of uses before you need to replace them. The bricks are affordable but they cost a little more than regular bricks.
If you are hoping to get the best price on the bricks you are going to have to do a little shopping. Compare prices from a few different Firebrick manufacturers and make sure that the price includes shipping. Some retailers won’t include the shipping price so it looks like they offer the best price, but when you factor in shipping, the deal isn’t quite so good. Silica insulation bricks are a cost effective way to get more out of your furnace or kiln with going through the replacement process.
