Floor insulation on the loggia is carried out by polystyrene foam or foam. It is better to dwell on each of these materials more details.
Polistyle foam is popular among construction organizations due to low cost and ease in use. Small weight and good thermal insulation make it one of the leaders in the field of floor insulation and walls. Significant disadvantages are low strength and hydroscopicity, so you need to be as accurate in the work. Penoplex is essentially the same polystyrene foam, but with a more strong structure. It consists of small even particles, differs in durability, steadfastly tolerates low temperature and is not subject to aggressive media. Of the shortcomings, it is worth highlighting a fairly high cost, the combustibility of the material and some installation features.
The technology of insulation of balconies and loggias using a foam implies the use of wooden bars, from which builders make up a grill for the future placement of plates.
The insulation of the loggia price for work depends solely on the materials, wishes of the customer and the total area of the room.
