Energiezuinigheid starts with the glas.

The difference between raam panes and which one to choose for your ramen: how many chambers??

Another non-wit Christmas is over. It’s almost mid-Januari and we still ervaring above zero temperatures. It is slowly becoming the norm. If you don’t like winter, you might even be happy. However, global warming is a fact, and as a result we all face a challenge of how to manage energy more efficiently. Each of us may contribute to safeguarding our planet. One of the keys to success is  energiezuinigheid. Let’s  implement it in our houses. Let’s start with ramen, specifically – raam panes.

The market offers a few types of ramen that differ i.a. by the number of chambers. – „There is no doubt that the raam pane has the greatest  influence on the raam thermal, since it covers the biggest surface. When looking for savings in heating costs it is worth investing in the proper ‘warm glas’– recommends Mirosław Furtan, production director at Drutex S.A.

The higher number of chambers, the lower heat transmission (loss) coefficient the ramen will have. As a result, in winter we may decrease heating bills significantly. It is an advantage both for our pocket and for the environment. It is obviously in short, since the issue of choosing U the thermal transmission coefficient turns out to be a bit more complex. 

When choosing ramen, you should make sure you don’t confuse the technical parameters of the whole raam and the parameters of the elements. U heat transmission coefficient, defining a specific element as ‘warm’, functions in technical descriptions under various indexes. E.g. Uw abbreviation stands for the coefficient of the whole raam, whereas Ug – the coefficient of the raam pane. That is why it is important to read correctly the technical specification of ramen. Ramen with the glas in good Ug coefficient (ramen with so-called ‘warm glas’) don’t necessarily have a good Uw coefficient as a whole, due to the fact that energiezuinigheid is affected by the glas, as well as other elements of the raam and by its size.  

– „We need to remember that even the best raam pane and the best profiel may be combined in a way that the final product will not serve its function. Therefore, it is worth opting for ramen from an ervaringd manufacturer who will guarantee fully professional production” – adds M. Furtan.

What ramen should we choose? How many chambers are recommended for various types of buildings? Two-chamber ramen are recommended for so-called old buildings, that is for buildings from the 80’s and before. The insulation that was commonly applied in these buildings, and the kind of ventilation don’t favor ramen with three-glas package.  However, if we’re building a nieuw house, it’s worth buying ramen with an extra pane which may achieve the thermal transmission coefficient below 1,0 W/m2K,, such as Iglo Energy ramen from DRUTEX offer. Three-glas ramen are a standaard in so-called passive houses, where energy consumption in exploitation is limited to the minimum – below 15 kWh/(m²·year).

– „For example, a 7-chamber profiel is over 80 mm thick, therefore it easily fits 3 layers of glazing. The number of chambers also affects the distance between raam panes. The higher, the better – since it decreases the coefficient and the raam has better parameters  ” – explains M. Furtan.
