Posted by Andrew Oldroyd on May 21st, 2019
Have you made up your mind to get insulation panels for your house or office but are still confused about what type of insulation panels do you want? If your answer is a yes, then rigid foam insulation can be a good option for you. Foam insulation is one of the mostly used insulation due to its large area of application, ease of use and the cheap rates. It is becoming highly popular among the masses as it ensures good insulation from external conditions and temperature and also comes in cheaper rates than other insulation options. This effective yet cost-effective insulation can be bought by you without any special ordering. You can buy it from any store easily or order it online without much hassle. But before buying rigid foam insulation you must first get your facts clear about it and then decide whether and what to buy to best suit your needs and requirements.
What do you mean by foam board insulation and what does the R-value signify?
The foam board insulation has emerged as a great alternative for the usually used fiberglass batt insulation panels. This is so because the rigid foam insulation boards R-value per length of thickness is better as compared to other insulations that are generally used in most places. Also, they are much cheaper. Apart from this, they offer great ease of work and great moisture resistance.
The rigid foam insulation board R-value is an important factor as it is the measure of the resistance that the insulation offers to the flow of heat across the insulation panel or board. Hence the better r-value of the foam insulation is also one of the major factors of its growing demand.
What types of foam insulation boards are available?
There are majorly 3 types of foam insulations available. They are-
1.Expanded polystyrene (EPS), which has the r-value of 4 per length of thickness and is the cheapest of all types. It is useful for insulating the roofs, foundation walls, and the sidings.
2.Extruded polystyrene, which has an r value of 5 per length of thickness. It is capable of limiting the air movement due to its groove and straight edgy structure. It is mainly used in foundation bases and can be found in various sizes.
3.Polyisocyanurate (Polyiso), which has an r value of 6 per length of the thickness. It is denser and costlier than other types. It is capable of reflecting back the heat due to its foil faced structure. It is beneficial to be used in the attic or under sidings.
