TBC compliance

Article 15 of the HE (Energy Saving) Basic Document of the Spanish Technical Building Code lays down the requirements on this subject as point 15.1 states:

“Basic Requirement HE 1. Energy-Demand Limitation:  all buildings will have an enclosure of such characteristics that limit the demand for necessary energy in order to reach thermal comfort depending on the climate of the city/town, their use, winter-summer cycle as well as on insulation and inertia characteristics, air permeability and solar radiation exposure thus reducing the risk of surface and interstitial condensation dampness which can damage their characteristics and treating thermal bridges properly so as to limit heat gains or losses and avoid hygrothermal problems”

FoamLime system complies with the insulation and salubriousness requirements laid by the TBC even in cold regions and provides excellent results both in new construction and on traditional enclosures.

FoamLime complies with the TBC and reduces energy consumption used HVAC --Heating, Ventilating and Air Conditioning—dramatically. An example of a comparison calculation on an enclosure without insulation and the results of applying the FoamLime system over said enclosure is featured below.
