Timber Bubble Seals

Bubble seals are designed to be used as replacement seals in timber frames on windows and doors. They are ideal for timber casement windows and can also be used on the top or bottom of sash windows. Over time the existing seals around your windows and doors may have compressed, perished or become less effective at keeping water and draughts out of your property. Replacing these seals is essential for preventing damage to your home, saving you money and keeping you warm and comfortable.

These timber bubble seals fit directly into the timber frame and create an air and watertight seal when the window or door is closed. The rigid foot is manufactured from high-quality Propylene which contains flexible fins that spread into the groove and help hold the seal in place. They can be easily cut to the correct length using a pair of scissors.

Bubble seals are available in a range of colours and sizes, depending on the size of the gap you need to seal.

Frequently Asked Questions

Our timber bubble seal is available in three different sizes, depending on the size of the gap you need to seal. To identify the best replacement section, measure the gap between the door or window and the frame. This will allow you to purchase a seal based on the size of this gap.

  • A 5mm bubble will seal a gap between 2mm and 4mm
  • A 6mm bubble will seal a gap between 2mm and 5mm
  • A 8mm bubble will seal a gap between 3mm and 7mm

These products are designed to be fitted into a groove in your window or door frame. This groove will need to be 2.5mm to 3mm wide by 6mm deep.

Timber bubble seals are designed to be pushed into the groove around the frame on your window or door. You need to ensure that this groove is clean, dry and free from dirt or debris before inserting the seal. Cut the seal to the required length and gently push it into the groove all the way around the frame. Test the window or door by gently opening and closing it to ensuring a smooth operation and closing movement.

Deciding on the best replacement bubble seal for your window or door may seem like a complicated task. Although this section may not seem like the most important part of your window or door, it is essential for reducing draughts, water ingress and keeping your home warm and comfortable.

Our extensive range of bubble seals allows you to choose a replacement section that fits the gap you are looking to fill. All of these products are manufactured from a high-quality Polyurethane and Polyethylene and have been specifically designed for residential and commercial windows and doors.

For further information or technical support with choosing the best replacement section for your home, you can get in touch with our knowledgeable team. If you would prefer, you are welcome to send us a sample of your existing section for identification. We can use this to help you identify a suitable replacement.
