THERMAL INSULATION IN FACILITIES

THERMAL REHABILITATION FACILITIES

The Technical Building Code (CTE) in its core document DB-HE2, establishes the minimum requirements for all installations of the buildings either new construction and for those communities where rehabilitation work to amend it make their initial installations.

This basic document of the CTE is completed by the new Regulation of Thermal Installations in Buildings (RITE), approved by Royal Decree THERMAL INSULATION, which came into force on February 29, 2008. Both documents set out the requirements for energy efficiency and safety to be met by thermal installations in buildings to meet the demand for welfare and health of people.
Thus regulating benefits in relation to the thermal insulation of pipes that allow a better distribution of heat and cold, energy efficiency of installations and energy recovery.

Good thermal insulation on site allows the reduction of energy losses in the facilities and will depend on the initial conductivity coefficient, the practical behavior of the installation, the insulation thickness, the temperature of the outer and inner surfaces and the diameter pipe. There are two more insulating materials used in the rehabilitation and insulation of thermal installations: the elastomeric foam and polyethylene foam.

Both the elastomeric foam such as polyethylene foam have a number of advantages such as its flexibility which promotes ease of installation, high mechanical strength and diffusion of water vapor, good weatherability with low water absorption and ultraviolet rays are physiologically neutral products manufactured CFC and HCFC and manufactured in a wide range of sizes and thicknesses which may include adhesive on one side.

Rehabilitation and insulation of heating systems using elastomer or polyethylene foam also meet other requirements of some thermal insulation such as their good behavior in fire and noise, being useful as acoustic insulation for noise from both the pipes and, due to air flow and temperature changes, as the noise from the ducts due to air flow through them and vibration ventilation mechanisms.
