About thermal conductivity
A single number cannot be characterized as anything, so do not try this with such an important thing as the thermal conductivity of insulating material.
Let's say that, despite all the difficulties, we have developed an air barrier.
The efficiency of the polyurethane foamsprayed on site is mainly due tothe airtightness created at that time.
The major area of use of polyurethane insulation is the thermal insulation and waterproofing of agricultural and livestock buildings.
Insulation may only be carried out on water, dust and grease-free surfaces. Renovation of old, faulty waterproofing does not require the dismantling of the old insulation.
R-value is resistance to heat flow rate; however, it only measures the resistance to thermal conduction.
All materials, including those used in the construction industry, conduct heat.
