60mm Novia Reflective Membrane Lap Tape (RMLT) - 50m roll

60mm Novia Reflective Membrane Lap Tape (RMLT) is a single-sided, metallised polyester edge and lap sealing tape coated with a high-performance, cold-weather solvent acrylic adhesive. Specifically developed to complement Novia® MirrorWrap W1 reflective wall breather installations, this low-emissivity tape prevents thermal breaks at membrane overlaps while maximising airtightness and wind resistance across the building envelope. It is a high-specification, low-emissivity jointing tape engineered to create a continuous reflective finish and airtight seal across reflective breather membranes.

CHARACTERISTICS

• Continuous Low-Emissivity Finish: Eliminates thermal gaps across membrane joints, preserving the full radiant heat reflection and thermal efficiency of reflective breather systems.
• Cold-Weather Solvent Acrylic Adhesive: Engineered for reliable, high-tack bonding even in demanding UK site conditions, maintaining strong adhesion down to low service temperatures.
• Self-Wound & Liner-Free: Supplied without a backing release liner for faster application on site, eliminating paper waste and trip hazards on scaffolding.
• Enhanced Airtightness & Weather Resistance: Seals external overlaps cleanly against wind uplift and air leakage when paired with a double-sided lap tape.

APPLICATION

• Reflective Wall Breather Membranes: Primary lap and edge sealing tape for Novia® MirrorWrap W1 and compatible foil/metallised breather membranes.
• Timber Frame & SFS Construction: Sealing vertical and horizontal overlaps behind ventilated rainscreen facades and masonry cavities.
• Penetrations & Repairs: Over-taping minor surface abrasions and sealing around service penetrations in reflective external membranes.
