Bubble Gaskets | Glazing Gaskets

Bubble Gaskets serve a particular role. They are instrumental in keeping door and windows sealed and watertight. Yet, not everyone is aware of what a bubble gasket is. To help with this, and clear up any confusion, we’ve put together a short introduction to bubble gaskets.

So, what are bubble gaskets?

To begin with, let us take a look at what a bubble gasket is. Each gasket has a distinctive shape. A bubble gasket has a doomed or curved top hence the name. A gasket is used on either a window or a door. Gaskets are placed between the part of the door or window that opens, and the frame of the window or door. The top bubble compresses when the door or window is closed. This often referred to as a compression seal. This seal ensures that there is no space for dirt, water or draughts to pass between the two.

Usually, you’ll find yourself replacing the bubble gasket when it has become worn out. It is unable to provide a sufficient compressive seal. This is often due to a high number of compressions taking place. Every gasket has a lifespan and wear and tear comes into play. You don’t need an adhesive or any particular tool to fit one. Instead, you’ll find that the bubble gasket just pushes into place with ease into a channel. This makes it an easy to replace part of the window which provides an airtight and watertight seal.

A bubble gasket is not much different from a flipper gasket. The primary differences is the shapes and sizes of the two types of gaskets. Both perform similar functions. Different gasket styles may be more effective in various types of windows or doors. They all cut down on the number of cold spots and places where heat can escape a room.

When should I replace bubble gaskets?

The best time to replace a bubble gasket is when the compression seal begins to fail. You’ll notice that the gasket will stay active for a long time. At some point the pressure and constant use will become too much. The gasket will fail to return to it’s former shape and will be far less effective. You’ll begin to notice that the heat will escape the room, or there is a draught. That is the perfect time to get a new bubble gasket.

The bubble gasket is an important component. It ensures that you can keep the warm air in a room and prevent any cold spots from becoming an issue. The seals will need replacing now and then, so you’ll need to get a new gasket. That is a small price to pay for creating a proper compression seal between the frame and the door or window. Replacing a bubble gasket will ensure that hot air does not get out and cold air does not get in. Replacing the glazing gaskets before the winter months is ideal. This is when keeping hot air in will mean the difference between feeling warm or chilly.
