Tytan horizontal wall insulation membrane 0.25 m x 50 m roll (880384)

Tytan horizontal wall insulation membrane is supplied as a narrow roll designed for creating horizontal damp-proof courses and sealing joints in masonry and wall foundations. The product is intended for use where a continuous moisture barrier is required to prevent rising damp and to improve moisture protection in both renovation and new-build projects. The 0.25 m width and long roll format make it practical for insertion between masonry layers, beneath window sills, and at foundation level where space or access is limited.

Advantages

The membrane is manufactured to provide a durable, flexible barrier that conforms to uneven surfaces and fills gaps between course layers. Its roll format allows controlled application along long runs without frequent joins, and the narrow width is suited to confined or precise installation points. Material properties ensure resistance to common construction site stresses while maintaining a slim profile that integrates easily into brickwork or blockwork joints.

Suitable for

• Creating horizontal damp-proof courses in masonry walls
• Sealing wall foundation joints and laps
• Retrofitting moisture barriers during renovations
• Installation beneath window sills and door thresholds

Key specifications

• Roll width: 0.25 m
• Roll length: 50 m
• Form: flexible membrane supplied in a continuous roll
• Intended use: horizontal damp-proof course and joint sealing in masonry and foundations

How to use

Prepare the masonry surface by clearing loose material, dust and moisture from the installation area. Position the roll so the membrane lies flat within the mortar bed or at the designated course level, ensuring full contact with adjacent masonry units. Overlap ends where necessary to maintain continuity and follow standard building practice for mortar joints and bed depth to avoid displacement. Trim the membrane to required lengths with a sharp knife and ensure it is embedded securely in the mortar or construction adhesive used for the wall build-up.

Usage recommendations

Store rolls flat and protected from prolonged UV exposure and extreme temperatures prior to installation. Use compatible mortar or adhesives and avoid exposure to sharp edges that may puncture the membrane. For retrofit installations, verify wall condition and plan for adequate lap lengths and sealing at penetrations or corners according to local building regulations.
