Self-adhesive EPDM P-profile gasket for windows and doors Stomil Sanok 100 m, brown (model SD-39AX/4, MPN 08785)

Self-adhesive EPDM P-profile gasket by Stomil Sanok is a continuous sealing strip designed for windows and doors. Supplied as a 100 m roll in brown, the gasket is made from vulcanized EPDM rubber which offers resistance to weathering, ozone and a wide temperature range. The P-profile cross-section compresses to fill gaps in frames and sashes, forming a durable seal that reduces drafts, moisture ingress and heat loss in both residential and commercial joinery.

Advantages

The EPDM composition ensures long-term elasticity and resistance to UV, ozone and temperature fluctuations, maintaining sealing performance over time. A self-adhesive backing simplifies installation and enables continuous application along frame perimeters without mechanical fasteners. The P-profile geometry provides effective compression sealing for uneven or variable-width joints while the brown color integrates discreetly with many window and door finishes.

Suitable for

• Sealing gaps between window frames and sashes to prevent drafts
• Door frame and threshold sealing to reduce heat loss and moisture penetration
• Thermal insulation improvement in residential and commercial windows
• Replacement of worn or hardened seals in renovation projects

Key specifications

• Material: EPDM rubber (vulcanized)
• Profile type: P-profile (compression sealing)
• Length: 100 m roll
• Color: brown
• Adhesive: self-adhesive backing for direct application
• Environmental resistance: weather, ozone and UV resistant; suitable for wide temperature range

How to use

Prepare the frame surface by cleaning and degreasing to ensure good adhesion. Measure the required length and cut the gasket from the roll with scissors or a utility knife. Peel off the protective liner and press the self-adhesive side firmly onto the frame or sash, ensuring the P-profile lip faces the gap to be sealed. Apply continuous pressure along the length to secure adhesion and compress the profile slightly to achieve the intended sealing effect. For best results, install at moderate temperatures and allow the adhesive to bond according to ambient conditions.

Usage recommendations

Store the roll in a cool, dry place away from direct sunlight and solvents. Before application on painted or sensitive surfaces, test adhesion on a small inconspicuous area. For edges and corners, cut and miter joints cleanly to maintain continuous sealing. Replace the gasket if signs of cracking, permanent deformation or loss of elasticity appear.
