What is a rubber edge?

Edge rubber is a flexible seal, most often made of rubber or a rubber compound, that is installed on the edges of carpets, floor skirting boards, access openings, door frames and other penetrations. Its purpose is to prevent dust, draft, air and sound emissions, improve comfort, protect structures and extend the service life of the material.

Why install a rubber edge?

1. Tightness and energy efficiency
   Edge rubber prevents air leaks in door frames and window edges, which reduces heating and cooling costs.

2. Safety and comfort
   Softens edge bumps and prevents slippery carpet edges – improving safety on indoor walkways.

3. Structural protection
   Prevents moisture and dirt from entering structures, which increases the longevity of floors, frames and walls.

4. Noise reduction
   Helps reduce the sound of steps or doors closing.

Materials and types

Edge rubber is often made from EPDM, NBR or PVC-based rubber compounds. When making a choice, it is important to consider:

• Rubber type: EPDM is weather-resistant, NBR is chemically resistant, PVC is inexpensive and easy to work with.

• Shape and profile: Corner shapes, U-, L- and S-profiles for carpet or strip use.

• Hardness and elasticity: Low Shore value for softness, high support and shape retention.

Edge rubber selection guide

1. Measurement and fitting:
   Measure the width and depth of the installation locations. Leave a little extra for flexible installation.

2. Temperature and chemical resistance:
   For indoor use, standard edge rubber is sufficient. For outdoor or exposed areas, EPDM is recommended.
   If the area is exposed to oils, chemicals or grease (e.g. garage), choose NBR.

3. UV and weather resistance:
   EPDM is highly resistant to UV radiation and temperature fluctuations, making it also suitable for outdoor seals.

4. Installation method:
   The edge rubber can be attached self-adhesively, stapled or glued to the correct profile.
   Remember to clean the installation area thoroughly before attaching.

Installation tips

• Clean the floor or edge thoroughly.

• Cut the edge rubber to fit, making sure the corners are cut straight.

• Remove the protective plastic from the pads (if self-adhesive) and press the rubber firmly onto the surface.

• Use a weighted strip or tape to secure the attachment while the glue dries.

• Finish the cut corners neatly on the adhesive side.

Maintenance and durability

• Purifying: Wipe the edges with mild soapy water – avoid strong solvents that can embrittle the rubber.

• Check: Before seasonal or surface repairs, check the condition of the rubber and its joints. Replace if cracks, hardening or loosening are observed.

• Duration: High-quality EPDM edge rubber lasts 15–20 years indoors, and approximately 8–10 years in exposed areas.
