Thermal Insulators

The sun has the ability to overheat any room with large openings. The amount of incoming solar radiation depends directly on the orientation of the opening. All this radiation is diffused to walls, floors and furniture, which absorb some of it and raise the temperature.This is why energy glazing was created.

This type of glazing (double or triple glazing) has a coating of tiny metal oxides on one side which does not allow heat to transfer from the interior of the house to the exterior environment or vice versa, thus saving energy.

Heat transfer coefficients

Light transmission coefficient (LT): this is the coefficient that expresses the percentage of the light energy (the visible part of the total spectrum of solar radiation) of helium that passes through the vitreous humour in relation to the total emitted light energy.

Thermal transmittance coefficient or coefficient K, (U-Value): this coefficient expresses the power that one has to pay in order to compensate the thermal losses for each square metre of albedo and for each degree of temperature difference between indoor and outdoor space that one wants to maintain (watt/m2*Co).

Solar Factor (g - Value) or SolarFactor (SF): a. This factor gives us the measure of the greenhouse effect that we should expect from a glaciation. It expresses the percentage of the total incident solar radiation that will eventually pass through the glazing into the interior space.
