Polyurathane has a smooth foam structure. The 90, 95 % of the cells in its structure are closed. This situation enables the heat insulation of polyurathane to be perfect, in other words it to be the best insulator in the world.
They are the foams with the lowest heat conductivity coefficient . ( ƛ = 0,0023 Watt/K.h.)
Its usage intensity is produced between 30-40 kg/m3 and 1200 kg/m3.
Although polyurathanes have closed cell structure, they can provide sound isolation up to 50 decibel.
They are good humectants and retentive.
Polyurathanes have a good adhesion property. They can adhere to any surface they are applied.
Product alternatives are unlimited since they can take the shape of every mould applied, like as in the liquids.
Although they are in the B3 non-combustibility class, they can be drawn to B2 ,B1 and even A class combustibility level with some additions.
Polyurathanes have high dimensional stability. As they show no dilation between -30 and +80 °C, they don't seperate from the surface they adhered.
Polyurathanes are long lasting isolation and decoration materials. It is possible to see decrease in isolation value in the first 15 years 10 % quantity, in 30 years 15% quantity. Conductivity values increases to ƛ=0,0025 – 0,0027 Watt/Kh.
Polyurathanes don't produce bacteria, they don't decay and stink, they are up to date and technologic products with hygenic features. In this sense, these products are enviromentally friendly products.
As polyurathane external wall materials don't include the chemicals the common plaster types include, your housepaint becomes long lasting, its colors remains more lively, it becomes more durable against external climate conditions.
