Lyvanas
Draught excluder

The draught excluder from LYVANAS made a good impression in our test. There are two draught excluders in a set, whereby the consumer can choose between the color variants black and white. The item basically measures 88 x 10.5 x 3 cm, whereby the length can be cut or shortened to fit the door. The product also fits standardized doors with a width of 4 cm. It is particularly noteworthy that each draught excluder consists of a high-quality, washable cover. However, the consumer must insert four foam rollers inside this cover before use. The draught excluder ensures that air can no longer flow under the door on both sides, thus stopping the draught. Nevertheless, the product produces grinding noises during use.

Advantages

✅ High-quality materials
✅ Stops draughts
✅ Perfect fit for standardized door width
✅ Can be cut to size
✅ Cover is washable
✅ Satisfaction guarantee of two years

Disadvantages

❌ Does not work with door threshold
Grinding noises
Foam rollers must be inserted by the consumer themselves

The first impression

Packaging and labeling

ℹ️ Here we take a closer look at packaging. Sustainability is becoming an increasingly important factor. In addition, adequate protection of the product must of course also be ensured.

CriterionRemarkScore achieved*
Product protectionPlastic bag85 points
Sustainability PackagingPlastic packaging with adhesive tape on the corners and around foam rolls45 points
Product labelingWarning to minimize the risk of suffocation, but no air holes in the plastic packaging. Label with material composition and care instructions80 points
MiscellaneousPackaging box was slightly damaged83 points
Total73 points
Weighting: 15%
*The maximum score is 100 points

After a very short delivery time, the draught excluder was delivered in a slightly damaged cardboard box. Inside this box, the product was wrapped in a plastic bag, with the corners of the plastic bag additionally taped. There is also a sticker on this bag with a warning to minimize a potential choking hazard. However, there are no holes in the plastic packaging to minimize the risk of suffocation. In addition, the cover of the draught excluder has a removable label with the material composition and the appropriate care instructions. The accompanying foam rolls are wrapped in adhesive tape. In summary, the product is well protected, but the use of adhesive tape is superfluous as it neither contributes to product protection nor is it sustainable.

After unpacking

Package contents and instructions

ℹ️ Most people’s first impression after unpacking is immediately memorable. Are the contents of the package complete and does the manufacturer make it as easy as possible for me to use the product straight away?

*The maximum score is 100 points

Two covers and eight foam rolls are supplied in a pack. The product also comes with instructions for use in five different languages and a removable label with care instructions. The manufacturer’s contact information can be found in both the instructions for use and the aforementioned label. The manufacturer has also included several messages of thanks to the consumer in the product packaging. In summary, it is clear that this is an extremely well thought-out and customer-friendly product.

Product processing and appearance

ℹ️ Before we start the practical test, we take a close look at the product processing. How high quality are the materials used? Is the look and feel satisfactory?

CriterionRemarkScore achieved*

*The maximum score is 100 points

A closer look at the draught excluder reveals that its cover is of very high quality and extremely well made. This can be seen in the neat seams and the thick and elastic material of the cover. The cover also impresses with its very soft fabric made of rubber and polyester, which is pleasant to the touch. In addition, the foam rollers supplied are robust and not too soft, which is why they do not wear out too quickly. All in all, the product is extremely stable, which is why it can be expected to be used over a long period of time.

This is what our practical test showed

Does the manufacturer keep its advertising promises?

ℹ️ Our practical test is the most relevant and therefore the most important. Here, the product has to undergo a wide range of criteria and tests. We check the functions and product promises of the test article.

CriterionRemarkScore achieved*
Stops draughts and saves energyPrevents air flow95 points
prevents noise, odors and verminNo noise reduction found in our test, generates grinding noises76 points
Can be cut to size and double-sidedCan be easily cut to size94 points
Precisely fitting to standardized widthFits doors with a width of 4 cm, not suitable for door thresholds89 points
Remains in position when opening and closingFoam rollers sometimes slip out of the cover easily80 points
Total87 points
Weighting: 30%
*The maximum score is 100 points

After taking a closer look at the draught excluder, we put it through a practical test. Before we could start our test, the foam rolls were inserted into the cover and cut to fit the size of the door. It was then very easy to slide the draught excluder under the door. During use, the product scored particularly well in terms of its ability to stop draughts underneath the door. However, we were unable to detect any noise reduction or odor control in our test. We also noticed that the draught excluder makes grinding noises and that the foam rollers easily slip out of the cover after prolonged use. Unfortunately, the product is not suitable for light door thresholds as it cannot overcome them.

Price/performance ratio

and ratings from consumers

ℹ️ Finally, we look at how the product compares to the competition. Can it keep up with the competition in terms of price and quality?

CriterionRemarkScore achieved*
Price / performance ratiogood92 points
Total92 points

*The maximum score is 100 points

Prices of up to €90 .00 are charged on the Internet for equivalent products. Very inexpensive products are available from as little as €9 .99. The draught excluder from LYVANAS is currently in the lower price segment with a price of €15.98. The price ratio is very good for the quality and scope of services you get.
