Brush strip seal offers an excellent way to reduce air leakage and draughts around windows and doors, helping to insulate buildings during the colder months and prevent thermal transfer during warmer months.
Prevent Thermal Transfer & Improve Energy Efficiency
Brush seal helps to reduce heat transfer from outside or between different air-conditioned rooms or areas during warmer months. This helps make your space more energy efficient by adding another layer of thermal insulation, reducing energy waste and energy bills. Brush seals help to make your indoor environment more comfortable by minimising temperature fluctuations and keeping temperatures stable and agreeable.
By preventing draughts, reducing air leakage, providing thermal insulation and reducing energy waste, fitting brush strip door seal is an effective way to improve your property’s energy efficiency.
Iain Banks, product marketing manager, explains:
‘Brush pile is extremely flexible, so it’s a great way to seal any uneven surfaces. The dense bristles compress and adapt to uneven surfaces around doors and windows, effectively closing gaps and preventing air infiltration. A brilliant draught-preventing solution for new and older buildings, brush strips can provide a cosy three times less air infiltration when compared with vinyl seals.’
Brush Strip Seal Maintenance
Brush seals are usually highly durable and can last a long time, but their lifespan depends on quality, usage, the environment they're exposed to, and proper maintenance. As a window and door product, brush seals are designed to withstand regular use and provide long-lasting sealing performance. If you maintain your brush seals by checking them regularly and cleaning debris from the bristles, you can expect them to last for several years.
Iain continues: ‘Our high-quality, flexible brush strip seal can be fitted to various doors, windows and surfaces. Its flexible profile adapts easily to different shapes, making it an excellent solution for multiple applications, including sealing, guiding, wiping, slowing down, and pressing. It’s also extremely durable and easy to fit and is available in various profiles and sizes and as self-adhesive or screw-fixing options.’
Brush strip seal is ideal for residential or commercial buildings. It can help improve insulation in living or working spaces, reduce noise pollution, and help prevent dust and insects from entering a building.

Frequently Asked Questions
Are brush strip seals better than rubber or vinyl seals?
Yes, especially on uneven floors and older frames. Rubber and vinyl seals need a perfectly flat surface to work. If a threshold is worn or slightly out of square, rubber buckles and leaves gaps. A brush strip uses thousands of flexible bristles that mould around uneven textures, cutting air leakage without sticking or jamming the door.
How do brush door seals help reduce energy bills?
They stop uncontrolled air exchange around the perimeter of the door. By blocking cold draughts in the winter and stopping heat transfer in the summer, your heating and cooling systems don't have to cycle constantly to maintain a set temperature.
Can brush seals stop insects and dust from getting inside?
Yes. The dense bristle matrix acts as a physical barrier. While air and dust pass easily through open gaps, the tight synthetic pile blocks street grit, airborne debris, and crawling insects from sliding underneath doors.
How long do brush strip door seals last?
High-quality synthetic brush seals easily last for years because the nylon bristles handle friction without cracking or perishing like rubber. To keep them working well, occasionally brush out any trapped grit with a stiff hand brush so the pile compresses freely.
