The customer samples are usually returned with our counter-patterns. When ordering and clearly identifying the pattern, these will no longer be returned.

The profiles in the poesia® construction program are shown in 1:1 scale.

You can always receive 18- to 20-cm-long samples from our range for free.

Samples will be sent within 24/48 hours after the order is received.

Yes, poesia® seals can be ordered via our webshop shop.mk-dichtungen.ch or via the webshops of our sales partners.

You have the possibility to place your order by webshop, e-mail, telephone, fax, letter or via our website. The order form can be found on www.poesia.ch

The colour information can be found in the profile tile in our poesia® construction program. We are happy to produce other colours in almost any RAL colour from 300 metres.

In order to cut a roll – usually 25 metres – we charge a cutting fee of CHF 15 per profile cross-section.

No cutting fee is charge for in excess of 25 metres.

The minimum order quantity is 1 metre.

Please note that orders under 25 metres are subject to a cutting fee of CHF 15 per profile cross-section.

Samples of 18 to 20 cm are free of charge

Yes, express delivery is possible on request. Please contact our sales for the corresponding additional costs.

If you wish to return your order, please contact our inhouse sales department on +41 (0)62 768 70 80 or contact us using the contact form.

Rule of thumb:

If you do not expect a refund, we accept all returns, which we will dispose of for free.

For refunds, we only accept complete, uncut and clean rolls.

The transport and shipping fees depend on the weight of the package. This is calculated at the end of the ordering process. The fees include shipping, packaging, handling and logistic services. Surcharges for bulk goods and freight forwarding are charged according to expenditure.

Packages that are more than 100 cm long or where two dimensions exceed 60 cm are considered bulk goods. Our bulk goods surcharges amount to CHF 12 per package/shipping tube.

Delivery will take place EXW in accordance with Incoterms 2020 from Unterkulm.

We send our products by Swiss Post. They are delivered within 24/48 hours of ordering.

Delivery by lorry usually takes two to three days after order placement.

Small amounts of up to approx. 15 boxes can be sent by mail; larger orders by lorry.

You can have the package sent directly to your desired address or collect it yourself at our pick-up window/box in Unterkulm.

Yes, you can add your seals to a complete frame – glued mitres. Choose your seals and enter the necessary information such as dimensions, measuring points and installation location.

The seals are available from 1 meter, then always in further 0.5 meter increments.

Our roll lengths are still 25 meters. There are few exceptions where the rollers or coils are 50 or 100 meters or more.

Rolled goods cannot be manufactured without winding impressions, because one layer reaches over the other. At these points, there may be slight winding deformations, which occur in the course of a few days on their own. You just must be patient.

A double-strand seal is manufactured as a secondary profile and divided by pulling apart before processing, so that each strand can be installed individually.

The anti-elongation thread is a so-called stretch protection. This is a thread that is inserted into the seal during production. This thread largely prevents the length extension of the sealing profile during installation. The seal does not pull together. This eliminates gaps between the seals in the miter area.

A breakout bridge performs the following functions:

• as a packing web for stabilizing the seal on the transport route, against possible compression. This must be removed after installation.
• as a functional bridge for breakout, in order to regulate the closing pressure in the component once.

Basically, all profiles can be equipped with a straight or smooth surface self-adhesive.

Unlinked corners are the quicker solution. We recommend welded frames or corners for use in wooden windows.

Smaller adjustments can usually be implemented but must be discussed on a case-by-case basis. In the event of major changes, a new tool usually must be made.

In principle, it should be avoided to coat seals. Paints, oils, thinners, etc. can cause consequential damage to the profile.

We can produce new tools at low cost from an order quantity of 300 meters.

New tool with first sample: 2–3 weeks; serial production after approval: 2–3 weeks

This depends on your taste and skill. Since seals can generally be cut rather poorly on miters with a pliers, the seal usually runs continuously at the top, while the two vertical-right lengths from below come up against it.

• TPE = Thermoplastic elastomers

• VMQ = Silicone rubber or vinyl-methyl-silicone

• EPDM = Ethylene propylene synthetic rubber

• NBR = Butadiene acrylonitrile rubber

• HNBR = Hydrogenated acrylonitrile butadiene rubber

• CR = Chloroprene Rubber / Neoprene

• FKM = Fluor rubber (formerly FPM)

• NR = Natural rubber

• PUR = Polyurethane

• SBR = Styrene butadiene rubber

• Foam rubber = largely closed porous and elastic foam

• Cell rubber = closed-cell foam-shaped elastomer

In this case, let our specialist staff advise you.

TPE is resistant to conventional synthetic resin and DD coatings, as well as to environmentally friendly, water-dilatable paints based on acrylic resin. Silicone rubber is resistant to conventional synthetic resin and DD coatings, as well as to environmentally friendly, water-dilatable coatings on acrylic resin basis.

Profiles made of TPE and PVC can be welded. All other materials must be manufactured in a ready-to-wear process.

The primer is used for pre-treatment of the surface for better bonding. Do not use a primer, there is no good connection.

After 10 to 15 years, we suggest that you check whether the seals are still functioning properly, particularly on frequently used doors or windows.

Test 1: Is the seal soft and elastic? Is the closing pressure normal?

Test 2: Check the seal tightness with a piece of paper. Windows and doors are considered airtight if you cannot pull a piece of paper through them.

Test 3: Maintenance products for seals may not contain any greasy or oily ingredients. These cause more harm than good.

We suggest that you check seals every five years. Hinges and locks can be maintained at the same time.

Ideally, you should install your seal with lubricant. A liquid soft soap or common washing-up liquid are suitable, for example. Apply with a sponge or cloth, only on the groove or the profile base. Our practical expander tools can also help you during installation.

You can always receive 18- to 20-cm-long samples from our range for free. However, you should limit yourself to about five to ten samples to keep our workload to a minimum.

Your seal is no longer in stock? Send us a sample and we’ll look for your seal on the market or make it ourselves.

Our specialists are available to give you advice. We would be glad to advise you.

Browser through our catalogue with over 4,000 profiles and compare your sample with our 1:1 illustrations. You can make a choice there and order or request a selection of samples.

Take a look at our homepage www.poesia.ch and compare your sample with the 1:1 illustrations.

Send us an approx. 10 to 20 mm piece of your sample by mail, including length specification, your preferred colours and any additional information. We will send you the suitable seal or, in case of doubt, a selection of sample gaskets, which you can try out.

Take your sample, make a straight cut and, using an ink pad, a clean stamp which you fax to us. We will then send you our suggestion right away.

It is difficult to measure the clearance for replacement seals when the window is closed. Here is the simplest method:

Take Plasticine, form one or more small round balls. With the window open, press these into the groove and close the window. You can now measure the crushed Plasticine with a vernier calliper and depth gauge to determine the exact clearance.
