Visqueen B/W Polisile Sheeting 8m x 25m 120mu — Professional Reflective Grow Room Lining
Best for: Growers building or upgrading grow spaces who need serious light reflection and durability without the premium price tag
Our thoughts
This is proper kit. British-made three-layer polisile that was built to take a hammering in silage production, but works brilliantly for grow room construction. The white side reflects light efficiently, the black side blocks it out, and at 120 microns it's thick enough to handle real use without being overpriced. One we recommend a lot for growers stepping up from basic tent setups.
Visqueen B/W Polisile Sheeting is a professional-grade dual-sided plastic lining designed to maximise light efficiency and control in indoor growing spaces. The reflective white side bounces grow light back into your growing area, squeezing more value from every watt. The opaque black side blocks unwanted external light and absorbs heat on warmer days. At 120 microns thick, this three-layer co-extruded polisile is durable enough for serious use — whether you're lining walls, partitioning spaces, or covering floors. It's the kind of material that doesn't complain and doesn't need replacing every season.
How it compares
This sits in the mid-tier durability and price bracket of grow room sheeting solutions.
- More durable than basic construction plastic, significantly cheaper than specialist horticultural films
- White side reflects 75-90% of light — competitive with most alternatives without the premium markup
- Thicker than light-duty options (120mu vs 480 gauge alternatives), thinner than heavy industrial grades (180–200mu)
- Proven three-layer construction — original design created for silage production, adapted for growing
- No certified lab specs, but real-world performance is reliable and consistent
In simple terms: it does the job properly without costing a fortune.
Usage guidance
Visqueen B/W Polisile works across several common grow room applications:
Grow room wall lining
Fix the white side facing inward to reflect light from your lamps back towards plants. This improves light utilisation and reduces the amount of wasted energy. The large 8m x 25m roll minimises joins and installation time.
Light deprivation and temperature control
Flip to the black side on warm days or to block external light during light-sensitive growing phases. It's quick to flip or reposition — no permanent installation needed.
Floor and base protection
The durability of 120 micron polisile makes it suitable for floor coverage, protecting surfaces from spills, moisture, and wear. The white side can reflect spillover light; the black side absorbs it.
Partitioning spaces
Create separate growing zones or staging areas. The dual-colour design lets you control light and temperature independently across different sections.

Who this is for
- Growers building permanent or semi-permanent indoor grow rooms from basic spaces
- Anyone upgrading from grow tents who needs professional-grade lining at sensible cost
- Growers running multiple growing zones and needing flexible light and temperature control
- Spaces where durability matters — sheds, greenhouses, converted rooms — and sheeting gets handled regularly
- Growers who want proven materials with real-world performance over laboratory-certified specs
Particularly well suited to small-to-medium UK growing operations where the 120 micron thickness offers the sweet spot between strength, flexibility, and cost.
Our take
This is solid, practical grow room lining. It reflects light efficiently, blocks what needs blocking, and won't tear if you handle it normally. The white-on-black design gives you genuine flexibility — you're not locked into one configuration.
At this price point and thickness, it's a proper step up from basic plastic without paying premium prices. Worth picking up if you're building or upgrading. Does exactly what it should, day in, day out.
