Summary

TLDRIn this innovative DIY experiment, the video explores the effectiveness of improving window insulation using an affordable solution: a PVC tablecloth versus a Tesa film. The presenter, assisted by Physics Professor Hundhausen, delves into the science behind window types and how these materials can significantly reduce heat loss, showcasing a practical demonstration with infrared cameras to compare the thermal properties of PVC and Polyethylene. With detailed measurements and cost analysis, viewers are guided on how to assess and enhance their window insulation economically. This exploration reveals both the physical properties and potential savings, making it a valuable resource for homeowners seeking cost-effective ways to boost energy efficiency.

Takeaways

😀 Andreas is testing inexpensive window insulation methods using PVC tablecloths and TESA polyethylene foil.
😊 He uses an infrared camera to measure the temperature difference with and without the foils.
🔍 The PVC tablecloth absorbs and re-radiates infrared radiation, reducing heat loss by ~25%.
🔍 The TESA foil transmits most radiation, but still reduces heat loss by ~13% due to the air gap.
📏 Andreas calculates the potential energy savings in Euros with help from a physics professor.
💡 The PVC foil insulates better, but looks terrible when applied.
💡 The TESA foil looks decent and is easy to install and remove.
💰 For Andreas' windows, the upgrade costs ~100€ for PVC foil or only 36€ for TESA foil.
😕 The kids would likely tear off the window foils, so Andreas plans to replace the glass instead.
📺 Andreas recommends checking out the physics professor's channel for more detailed explanations.

Q & A

What materials are used for the window insulation foils tested in the video?
-Two materials were tested: a PVC tablecloth and polyethylene (PE) tape from Tesa.
How does infrared absorption of the materials help insulate windows?
-Materials that absorb infrared radiation reflect some of it back into the room, reducing heat loss through the window.
What temperature reduction did the PVC foil and PE tape achieve?
-The PVC foil reduced the temperature by about 10°C and the PE tape by about 2-3°C.
How much energy savings did each window insulation method provide?
-The PVC foil saved around 25% energy and the PE tape around 13% compared to an untreated glass window.
How can you tell what kind of window glazing you have installed?
-Hold a candle up to the window at night - the number and size of reflections indicate whether it is double or triple glazing, and a blue tint indicates thermal insulation coating.
What was the cost for insulating the windows with each method?
-For the room shown, the PVC foil cost €93 and the PE tape cost €36 for all windows.
What are the advantages and disadvantages of each insulation method?
-The PVC foil insulates better but looks bad when installed. The PE tape has less insulation but stretches better for a neat appearance.
How much money can be saved per year by using these insulation foils?
-For the example windows shown, €40/year could be saved with the PVC foil and €20/year with the PE tape.
Why should the foil not be glued directly to the window glass?
-There needs to be an air gap between the foil and glass for the insulation effect to work.
What other options are there for improving window insulation?
-Replacing the glass with modern double or triple glazed windows with thermal insulation coating provides the best insulation.

Keywords

💡Fenster

Fenster refers to windows. The video is about improving old windows in the narrator's house by adding a plastic film to reduce heat loss. Fenster appears throughout as it is the core object being discussed.

💡Wärmeverlust

Wärmeverlust means heat loss. A key goal of the video is testing methods to reduce Wärmeverlust through windows in order to save energy. The narrator quantifies potential Wärmeverlust reductions from different films.

💡Infrarotkamera

Infrarotkamera refers to an infrared camera. The narrator uses it to visualize and measure the Wärmeverlust of different windows to test the effect of adding films.

💡Isolierung

Isolierung means insulation. Adding plastic films aims to improve the Isolierung of the windows to reduce Wärmeverlust. Isolierung is a key concept for the upgrades being tested.

💡Wärmeschutzverglasung

Wärmeschutzverglasung refers to thermal insulation glazing, a type of energy efficient window. The narrator compares adding films to old windows vs. installing new Wärmeschutzverglasung to reduce Wärmeverlust.

💡PVC

PVC stands for polyvinyl chloride, a type of plastic. One film tested is made of PVC. The narrator explains how PVC's properties affect Wärmeverlust.

💡Polyethylen

Polyethylen is polyethylene, another plastic. The other film tested is Polyethylenfolie. Its properties are compared to PVC.

💡Absorption

Absorption refers to a material absorbing radiation, like PVC absorbing heat radiation. This reduces Wärmeverlust but less than reflection.

💡Reflexion

Reflexion means reflection. Reflecting heat radiation back into a room is better than absorption for reducing Wärmeverlust.

💡Reversibel

Reversibel means reversible. The narrator notes Polyethylenfolie is good for rentals since it is reversibel - it can be easily removed without damage.

Highlights

Testet billige transparente Tischdecke und Tesa Folie zur Verbesserung der Fenster-Isolation

PVC absorbiert Wärmestrahlung, Polyethylen lässt sie durch - wichtig für Isolierung

Absorption hält teilweise Wärmestrahlung im Raum, Reflexion wäre besser, ist aber teurer

Tesa Folie reduziert Wärmeverlust um 13%, Tischdecke um 25% - mehr als erwartet

Tesa Folie kostet 18€, Tischdecke 88€ für Beispielfenster - Preisleistung bei Tesa besser

Tesa Folie sieht optisch besser aus als milchige Tischdecke

Je mehr Scheiben und Beschichtung, desto besser die Dämmung des Fensters

Anzahl Reflexionen zeigt Anzahl Scheiben, blauer Schimmer deutet auf Wärmeschutzbeschichtung

Fenstertausch bringt mehr als Folien, aber ist teurer. Folie für Mieter geeignet.

Tesa Folie einfach mit Klebeband anzubringen und wieder abzunehmen

Für Familien problematisch, dass Kinder die Folien abreißen können

Scheibentausch in Eigenleistung machbar und günstiger als Folien langfristig

Zeigte einfach und günstige Methode zum Test der Isolierung

Empfiehlt Kanal von Prof. Hundhausen für detailliertere Berechnungen

Hofft, Zuschauer konnten etwas über Funktionsweise lernen
