How to protect your home from heat?

High summer. The sun is shining brightly in the sky, heating the earth and causing temperatures to exceed comfortable levels. In such a situation, it is best to seek shelter inside buildings. But how can you protect your house or apartment from heat? And what influence can window joinery have on it?

Solar energy permeability factor

One of the most important parameters of windows is their thermal insulation. It protects the interior of the room against the conditions prevailing outside. In winter, this helps to keep the room warm, and thus – to reduce heating expenses. In summer, with the windows closed, it allows you to stay cool and limit the access of warm air inside.

In summer, windows with panes with a low solar energy transmittance coefficient g work well. This coefficient is expressed as a percentage (the higher the value, the more solar energy passes through the glazing), and it is influenced, among others, by number of glass panes forming a glass package. However, this can be a problem in winter, when a small amount of solar energy will not be able to provide a satisfactory insulation of the interior of the room. As a result, this may result in an increase in heating bills.

Unfortunately, climate change means that in the coming years we can expect more and more hot days and fewer really cool days. Thus, all expenses for air conditioning and cooling rooms can contribute to the drainage of the household budget, rather than heating them.

Solar control glass

Sunshade glass is another component of the window joinery that can help you fight the heat. Their main task is to protect the interior against excessive heating.

Solar control glass is divided into three types: absorption (Antisol), reflective (Stopsol) and selective. The first two types are currently used sporadically, and the most popular solution is selective glazing.

Selective panes are coated with metal oxides several times. This allows a coating to be produced that provides the desired level of reflection. In this way, the amount of solar energy penetrating inside is limited, and also prevents heat loss from inside to outside.

It is the most comprehensive solution available on the market. It allows the color of the glazing to remain neutral and combines high light transmittance with protection against excessive heating of the room.

MS beyond WINDOW offers three types of selective sun protection panes: Combi Neutral , COOL-LITE SKN and SunGuard SuperNeutral . They mainly differ in the variants in which they appear. All available types of glass are characterized by a high level of thermal insulation and an optimal ratio of light transmittance to solar energy transmittance. Thus, a lot of natural light enters the interior, and is nevertheless protected against overheating.

Facade blinds on large glazings

External covers

Along with windows with good parameters that protect the interior of the room from overheating, it is also worth installing external covers: roller blinds or facade blinds .

External screens slow down the heat transfer between the inside of the building and the outside. This is because they create an additional thermal barrier in addition to the glass.

An example of effective operation can be the mSun facade blinds , the installation of which on the facade of the building allows you to reduce the temperature in the room by up to 10 degrees Celsius (with an outside temperature of 35 degrees Celsius)! The installation of external covers therefore avoids air conditioning costs. Moreover, it is a better solution for the environment, as it reduces the demand for electricity.

Therefore, the combination of external shields with solar control glass with good thermal insulation parameters will significantly reduce the negative impact of heat on the interior of our home, apartment or office. As a result – to increase the comfort of staying, resting or working in a given room.

Terms of use

Even the best window frames with top-class glass inserts and external covers will not work in the fight against heat, if the user does not follow certain rules that must be followed in order to cool the room.

First of all, remember that the windows should be closed during the time of day with the highest sunshine and the highest temperature. The characteristic feature of heat is that it penetrates into colder places, so in winter it will “run away” from the interior, while in summer it will be quite the opposite – it will get there.

It is best to open the windows after dark and close them again in the morning, before the sun starts to heat the most.

On the other hand, external covers should be fully closed. Only in this way will they fulfill their role as an additional thermal barrier and limit the heat flow to the room.

In addition, we should also remember to regularly hydrate ourselves, wear light and airy clothes, and limit the use of heat-generating electrical appliances or minimize the cooking time. No kidding with the heat!
