Product FAQs & Fitting Guide

How will the seal look once installed?
The S312S1235 is crafted from high-clarity TPE, designed to blend discreetly with any modern interior. Unlike standard PVC, TPE offers superior resistance to high temperatures and humidity. It is engineered to maintain its structural integrity and transparent finish without melting or yellowing, ensuring your sauna or bathroom retains a high-end aesthetic over time.
Is this seal compatible with timber doors?
Yes. This universal profile is specifically engineered for non-standard installations. Moving away from traditional clip-on designs, it utilizes a robust semi-U adhesive channel. The industrial-grade, mould-resistant tape is pre-applied at our facility; simply remove the backing and press it onto any flat glass or timber surface to create a reliable watertight barrier. It is an ideal solution for bespoke door thicknesses or specialized frames.
Can this be used in saunas or steam rooms?
This is the primary advantage of the S312S1235. While most PVC seals may soften, deform, or omit odours when temperatures exceed 70°C, our TPE material is rated for extremes of up to 180°C. Whether for a domestic sauna or a commercial steam suite, this profile is designed to remain stable, resisting shrinkage or degradation in high-heat environments.
Is it suitable for curved glass?
Indeed. TPE is inherently more supple than PVC and possesses a "low memory" characteristic, allowing it to follow the contours of curved glass or bespoke screens with ease. The high-bond adhesive ensures the profile remains securely aligned with the curvature without the tension-related "spring-back" common in stiffer materials.
How should I install this sauna door seal?
  1. Trim: The 35mm fin is designed for versatility. If this is too deep for your specific gap, use the integrated cutting guide lines to trim the fin with heavy-duty scissors.
  2. Prepare: Thoroughly clean and dry the surface. Peel back the protective liner from the adhesive tape.
  3. Align: Carefully line up the seal with the edge of the door.
  4. Press: Apply firm pressure along the adhesive channel for 10 seconds to ensure a full bond.

Note: Allow the adhesive to cure for 8–10 hours before exposing to moisture or heat.

I require a 2-metre length for a side seal—is this possible?
While we supply this profile in 950mm lengths, you can easily achieve a longer run by installing two units end-to-end. When trimmed precisely, the joint remains discreet while maintaining effective water management.

High-Temperature TPE Sauna Door Adhesive Seal S312S1235 Installation Guide - Simba Anti-Mould Shower Seal

✓ DO’S

  • Direct Press: Fit by pressing directly onto the glass edge to protect the surface.
  • Deep Clean: Remove all UK hard-water limescale before installation.
  • Sharp Tools: Use garden pruners for a clean, professional finish.
  • Daily Rinse: Simply wash away soap suds after your shower.

✕ DON’TS

  • No Sliding: Never slide the seal along the glass; this risks scratching.
  • No Extreme Heat: Avoid water >70°C or hair dryers to prevent warping.
  • No Soapy Water: Do not use lubricants—they accelerate mould growth.
  • No Harsh Chemicals: Avoid bleach or acidic cleaners on the seal.
