Home improvement vapour control that helps prevent condensation and protect insulation in walls, floors and roofs. The Just The Job Supplies Vapour Check Barrier gives confidence during installation thanks to its semi-transparent green colour and wide roll format. Is the 125 micron thickness and selectable-cut option the right choice for your project?
⚡ At a Glance
- • Moisture Control: Helps stop warm, moist air reaching insulation and forming condensation
- • Best for: Builders and DIYers fitting insulation in timber frames, underfloors and roofs
- • Not ideal for: External weatherproofing or primary waterproofing where robust external membranes are required
Semi-transparent green vapour check suitable for walls, floors and roofs. Designed to protect insulation and reduce condensation and mould risk.
Reduce condensation, with 125 micron vapour resistance
125 micron thickness, described as 500-gauge, creates a robust vapour resistance layer that slows movement of warm, moist air into cold cavities. Lower vapour transmission reduces the chance of moisture reaching insulation and structural timbers.
Reduced condensation helps keep insulation dry and effective, lowering the risk of damp and mould. That makes assemblies perform closer to their intended thermal specification.
Faster alignment on site, with semi-transparent green material
High transparency allows studs, joists and beam lines to remain visible through the membrane during installation. The coloured translucency helps mark out cut lines without repeatedly moving the roll.
Quicker, neater installations because lining up fixings is simpler and more accurate. Fewer mistakes reduce rework and installation time.
Less material waste, with multiple cut length options and wide roll width
Available in a 2.5m width and selectable lengths so strips can be chosen to suit project dimensions and stud centres. Custom cuts reduce the need for excessive overlaps and trimming on site.
Tailoring roll lengths to the job reduces offcuts and overlap joins, delivering more efficient coverage and less waste overall. That makes planning and ordering cleaner.
✨ The 4 Key Reasons for Just The Job Supplies Vapour Check Barrier

❓ Frequently Asked Questions
Q: Can this be used on walls, floors and roofs?
A: Yes, descriptions state suitability for walls, floors and roof applications, including timber frames and underfloor work.
Q: Can I order the exact length I need?
A: Yes, multiple cut options are available and users can select preferred lengths in the material options to reduce waste.
Q: Will it help prevent mould and damp?
A: Yes, the vapour check helps reduce condensation and protects insulation, which in turn helps lower the risk of mould and damp.
🏆 Our Verdict
Suitable for builders, renovators and DIYers who need straightforward vapour control when installing insulation in walls, floors and roofs. The semi-transparent green vapour check, combined with selectable lengths, aids accurate installation and reduces waste. While overall cost depends on project size, the ability to order tailored lengths and reduce overlaps makes it a practical longer-term choice for moisture management.
