The energy balance is defined as being the combined heat insulation and solar control. Despite the saving in heating energy, we should not forget that solar uptake, which is so desirable in winter and spring, can lead to unwanted increases in the internal temperature in the summer months, causing added expense in cooling. In our latitudes, due to the variations in the elevation of the sun, the solar factor of the glazing is favoured (reduced) by an increase in the energy reflected. Nonetheless, the best treatment of transparent enclosures for summer use is achieved using solar-control reflecting glass.

The ideal glazing consists of a system which allows in large amounts of solar energy in the winter with low heat losses, but which forms an effective screen against excess solar heat in the summer, thus saving on cooling costs. And all this should be possible with natural lighting and the large glazed surfaces that are such a common feature of modern architecture.

Logically the best enclosure system will include the corresponding fixed and mobile solar protection systems on exterior walls, as well as suitable heat insulation.

With CLIMALIT, you can plan a glazing system for a building that combines the advantages of different types of glass in a volume.

The ideal glazing consists of a system which lets in large amounts of solar energy in the winter with low heat losses, but forms an effective screen against excess solar heat solar in the summer, thus saving on cooling costs.

Spain is a country with great climatic variations: sunlight varies from 2000 to 3000 hours a year depending on the region, of which approximately 1000 hours occur in winter, when heating systems are operating, and the rest in summer, when cooling systems are running.

Finding the best solution, in terms of heat and light, for the transparent parts of a building involves finding the right combination of the K, SF and LT parameters described above.
A building with a high level of heat inertia protected by good insulation in the external “skin” - both in the opaque and glazed parts, will enable reductions in the heat flow; will be relatively insensitive to variations in external temperatures; and will ensure good comfort and energy saving throughout the year.

The various arrangements of CLIMALIT are invaluable for achieving the right balance between energy, natural lighting and architectural design, offering the maximum comfort and saving, while also contributing to the protection of the environment.
