Aged eps

[richardbrown]

Whenever I ring Encon to buy eps they always say do I want it aged or not.

They say it must be produced then rested for however long to let it expand before fitting to the wall.

I have never heard of this from anyone else and if it must aged why give me the option of buying it not.

Anyone?

There is a period of time it should be left after it has been extruded. Cany think why encon would have it that early tho. Its usually cut from block after

All the manufacturers that I have used have allowed between 2 / 3 month s for ageing. Boards tend to shrink over time. I ve never been offered new or (unaged) boards though.

You must mean 2/3 weeks. Can you imagine the space needed to store eps in every size for 3 months

Jablite are manufacturing to order at the moment with a 5-7 day lead time. The ageing is a new one on me??

Thats what I meant by block its a huge block that sits in the chemical factory. Iys cut to board size after that.
So there is no way encon should have eps thats still active.

Thats what I was told about eps extrusion anyway but im goin back 10 yr and maybe social housing demand and the change to platinim has changed things

It should be aged for 4 weeks, JUB manufacture it and we have managed to reduce that down to 2 weeks. If it is not aged it will bow as it cures.

You mean phenolic or eps? or both. Phenolic bows months after production. Even on the wall. Reason why sto and others have/are removing it from their systems now.
