Allowing more natural daylight into living rooms and offices has several benefits. Roto products help building designers let in more light while still maximizing user convenience, safety and security.

As a window manufacturer, you need a hardware supplier whose products help you reach the limits of what is possible in modern glazing. One of these areas is the maximum size of windows.
There are many reasons for building designers to want to install larger glazed areas and let more light into buildings.

Energy efficiency

An obvious advantage of increasing the levels of natural light is that artificial lights will then be needed less often. Even modern energy efficient lighting uses some power, so savings are possible.

Another way in which power can be saved is the partial heating of buildings via sunlight. So-called ‘solar gain’ can be useful in winter, warming the interior slightly and reducing the amount of energy required from the building’s heating system.

In the height of summer, it might be undesirable to have too much sunlight because it heats a building too much and creates more energy usage by air conditioning systems. It is however possible to use special glazing or window treatments and films that diffuse sunlight and reduce the impact of heat gain.

Health benefits

There are other good reasons to maximize the levels of light in buildings, be they homes or workplaces. The main reason is maintaining the circadian rhythms or the natural ‘body clock’. Exposure to brighter light in the day and then gradually receding light as sunset approaches helps the body to maintain optimum levels of melatonin, the hormone that regulates the sleep-wake cycle.

When people have regular sleep patterns, they benefit in many ways. They are healthier, more alert, less prone to low mood and there is also evidence that better quality of sleep equals less susceptibility to serious diseases. The immune system also needs quality, regular sleep.

Good for business

It makes sense for employers to ensure that their staff work as much as possible in buildings with high levels of natural light. Staff with good levels of physical and mental health are more productive and less likely to be absent due to illness.

Visual design

In terms of design, natural light is also desirable because it enhances the colors inside rooms, making them more appealing. Lighter rooms also feel more spacious.

Openings provide advantages

Larger windows provide more benefits of natural light. If these windows can be opened, users also gain the advantages of allowing natural ventilation.
