Is polystyrene insulation any good?
Polystyrene insulation is very rigid, unlike its fluffier cousins. As an insulator, it can withstand extremes in temperature and is also a noise reducer. Unlike other insulation materials, it is waterproof and lasts a long time. All of these things make polystyrene insulation stand out as an exceptionally good product.
Is polystyrene bad for the environment?
Sadly, science has shown that the majority of polystyrene that’s produced ends up in the ocean. In turn, marine animals can die from getting polystyrene stuck in their digestive system. Naturally, recycling polystyrene can help put a stop to environmental pollution too.
Are polystyrene tiles safe to use?
Also the tiles must not be painted with gloss paint which will cause them to be flammable, they should only be painted with emulsion or fire retardant paint. So, the "new" (this has been the case for several years) style polystyrene tiles are SAFE. Quote.
Can polystyrene be stored in an unventilated area?
Though it only applies to large amounts of "fresh" polystyrene, being stored in a "confined, unventilated area". fresh polystyrene contains residual pentane and if large amounts of EPS materials are stored in a confined, unventilated area such as a semi-trailer truck, pentane may off-gas and create measurable airborne concentrations.

Why is it important to install glasswool insulation?
When installing other insulation types like glasswool insulation, it’s important to ensure that the area you are working in is completely dry, as moisture that becomes trapped can cause mould issues. Moisture can also cause batts to compact which lowers their effectiveness and essentially their R-value.
How does bulk insulation work?
Any type of bulk insulation works on the same principle, no matter what material is used. The aim is to create as many air pockets as possible inside the material. The more air you can trap inside your material, the more effective your material will be at resisting heat flow.
Is polystyrene a thermal insulator?
1) Polystyrene has a high ther mal resistance. Extruded polystyrene (XPS) and expanded polystyrene insulation (EPS) contain millions of air pockets trapped within the foam. Because the polystyrene itself is also highly resistant to heat, the result is a great thermal insulator which can give excellent R-ratings.

This is more expensive and more effective than expanded polystyrene insulation. It consists of smaller beads filled with a mixture of air and refrigerant gas. These differences make it a better insulator. The process used to make extruded polystyrene insulation gives it other beneficial properties.
Is insulation flammable?
Every product has disadvantages. It is very costly in the beginning, and it also is flammable. This means it has to be chemically treated, which adds to the overall cost. If exposed to the sun or temperatures over 165-degrees Fahrenheit it can degrade. This is very unlikely, however, as home insulation is not exposed to these conditions.
