If we analyze responsibility for heat loss for every structural component in an average house we can observe that:
- 20% of heat loss is due to the roof
- 25% of heat loss is due to the walls
- 20% of heat loss is due to the floor
- 35% of heat loss is due to the windows
Summarizing all of the above, we can easily conclude that the easiest, cheapest, cleaner and more efficient way to reduce heat loss, thus saving money for heating and cooling, is achieved by installing energy glasses with a soft coating.
What is the energy glass (Low-E);
New generation energy glass (Low-E) is a transparent glass, which has a coating of tiny metal oxides on one side. This coating prevents the transfer of heat from the interior of the house to the exterior surroundings and vice versa.
Energy glass and warm climate:
The energy glass:
- Reflects the sun’s infrared light (heat)
- Acts as a shield against the indirect heat from its surroundings
- Reduces cooling costs
The energy glass has the ability to reflect the infrared light from the sun (heat) and allow of only the visible light to enter. When sunlight strikes an object (pavement, loop, balcony, flowerpot etc.), it is heated and emits indirect heat, which tries to enter our space. The energy glass acts as a shield against such heat and prevents it from entering our interior space. This helps us keep our homes or our workplaces cooler in the summer, as not only the heat from the environment, but also the one that is emitted from various objects do not enter the interior thus keeping our place cool, with reduced cooling costs.
Energy glass and cold climate:
The energy glass:
- Maximizes the beneficial effects of the sun
- Acts as a shield against the heat trying to escape from the interior
- Reduces heating costs
The energy glass maximizes the beneficial effects of the sun. The energy from sunlight is absorbed by objects within the space, such as sofas and carpets, and basically is converted into heat. The energy glass acts as a shield against this heat and prevents it from escaping from the windows. Let’s not forget that the heat that exists in the interior moves towards the colder, cooler windows. The energy glass acts as a mirror and reflects the heat that tries to escape back to our space, keeping it warm, resulting in reduced heating costs.
Overall benefits of energy glass
The overall benefits of the energy glass can be summarized as follows:
- More efficient thermal insulation in winter
- Easier cooling in summer
- Reduction of the annual cost of heating and cooling up to 35%
- Substantial contribution to environmental protection
- Reduction by up to 70% of the incoming ultraviolet radiation that wears out carpets, curtains, furniture etc.
- Minimum cost difference from double glass
- Similar in appearance to plain glass
