tesa® INSULATION Weatherstrip Foam M

If a window does not close anymore after a tesamoll® sealing profile was attached to the window frame, you most likely used a profile which is too wide. The only solution is to remove the seal and replace it by a smaller size.

If you discover gaps of various sizes, use either tesamoll® PREMIUM FLEXIBLE or tesamoll® UNIVERSAL Foam. These products feature highly flexible foam, which is able to adapt to a wide range of gap sizes.

tesamoll® sealing profiles come in four qualities with distinctive advantages:
Silicone-based tesamoll® sealing profiles are extremely weather proof and temperature resistant. They come with a 15 year limited guarantee for durability.
Rubber-based tesamoll® a sealing profiles are weather resistant and water repellant. They are backed by an 8 year limited warranty.
tesamoll® sealing profiles made of closed cell foam are highly flexible and adjust to just about any window gap. Their durability is guaranteed for at least 4 years.
tesamoll® sealing profiles made of open cell foam are the preferred choice for indoor use, since they are not weather resistant. They are highly flexible to match a variety of gaps and offer a durability of at least 2 years.

A candle will already give you a good idea of the existence of gaps between window and frame. If you want to determine the exact size of the gaps, proceed as follows:
Insert a small strip of plasticine along the window frame. Close the window and open it again. The thickness of the plasticine will show you exactly how wide the gap is at various positions.
tesamoll® sealing profiles are placed inside the window frame and do not have any visual effect on the windows appearance. However, you should select the right type of profile. If the sealing profile is too wide, you will not be able to close the window.

Leaky windows push up energy bills and increase the risk of mould. A high‑quality, intact window seal keeps your home warmer and helps cut heating costs. Plus, many seals also offer extra protection against noise and dust.

All tesamoll® sealing profiles are resistant against temperatures between -50°C and +60°C. This makes them an ideal sealing solution for extremely hot days as well as extremely cold winter nights.

tesamoll® sealing profiles in different profiles and materials. The flexible and self-adhesive strips are designed to seal gaps of various sizes in windows and doors.
During hot weather, tesamoll® sealing profiles prevent hot outside air from coming in and keeps cool air inside the house. During cold and stormy weather, tesamoll® avoids any cold drafts and keeps heated air inside the house. Doing so, tesamoll® helps to save energy and can reduce energy costs by up to 40%.

If the window frame already features an adhesive sealing, it needs to be removed before attaching any tesamoll® sealing profile. If the window has a window sash with featuring a trapped rubber sealing, the tesamoll® sealing profile should be attached to the window frame in a way that it gets in direct contact with this rubber sealing.

If rooms stay cold even with the heating on, or you feel a draught, seal your windows as soon as possible. Condensation on the glass is another sign of leaky windows—add draught‑proof window seals to improve energy efficiency and prevent mould.

After pulling off a worn tesamoll® sealing profile, any remaining residues of the adhesive material can be removed with a standard household cleaning detergent.

Hidden gaps between window frame and window sash will prevent the window from effectively serving its function to separate the inside air from the outside air. Especially larger gaps will considerably drive up the costs for heating in the winter and air conditioning in the summer. The tesamoll® P-Profile rubber seal was developed to seal such gaps in order to prevent any exchange of air. They feature a special hollow profile and are designed to reliably fill gaps between 2 and 5 mm. The benefits are obvious: no uncomfortable cold draft, no loss of heat, no excessive energy costs. Experience shows that the resulting energy savings can be up to 35%.

In most cases, the homeowner or the freeholder/management company is responsible for window maintenance. If you’re a tenant, speak to your landlord. Act quickly with leaking or draughty windows—every day without properly sealed windows raises heating bills and increases the risk of damp and mould.

Condensation on windows is a warning sign for mould and damp. The most common cause is leaks or gaps in the window frame letting in cold air and moisture. In this case, seal your windows promptly with quality draught‑proofing and weatherproof window seals to prevent mould growth and improve energy efficiency.

If it takes very long to heat up a room, chances are that the doors and/or windows are not sufficiently tight. Another indicator are uncomfortably cold areas in front of doors or windows. If the room is equipped with an air condition, gaps in the windows and/or doors will allow cool air to escape and it will take more time to cool down the room.
There is a simple way to discover undesirable gaps between window and window frame: Hold a lit candle at various positions close to the window frame. If the flame of the candle flutters a lot, there are definitely wide gaps that allow an exchange of air. If it flutters just a little, the gaps are still wide enough to affect the room temperature. If it flutters only slightly, but it feels considerably cooler close to the window, there are at least small gaps to prevent economic heating or air conditioning.
Try to test the situation at different positions of the window frame. In this way you get a good idea of where the trouble spots are and are able to address it with a suitable self-adhesive tesamoll® sealing profile. If you discover different gap sizes, use tesamoll® STANDARD or tesamoll® Premium flexible. These products are able to adapt to a wide range of gap sizes.
