Greenhouse fabrics typically cost about $0.10-$2.50 per square foot, depending on whether the material is polyethylene film, shade cloth, insect netting, or a thermal curtain. Greenhouse size, fabric weight and UV rating, installation labor, shipping, and attachment hardware can raise the finished project price.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Greenhouse polyethylene film | $0.10/sq ft | $0.25/sq ft | $0.60/sq ft | Film price only; thickness and UV treatment affect rate |
| Shade cloth | $0.20/sq ft | $0.65/sq ft | $1.50/sq ft | Density, knit, and edge finishing vary |
| Insect netting | $0.15/sq ft | $0.55/sq ft | $1.60/sq ft | Mesh size and pest exclusion level drive price |
| Thermal curtain fabric | $0.80/sq ft | $2.00/sq ft | $4.00/sq ft | Specialty material; excludes operating hardware |
| Installed fabric project | $300 | $1,500 | $6,000+ | Small replacement through larger or complex jobs |
What greenhouse fabrics cost by roll and square foot
For a basic greenhouse covering, buyers often pay $0.10-$0.60 per square foot for polyethylene film, $0.20-$1.50 for shade cloth, and $0.15-$1.60 for insect netting. Those are material-only planning ranges; retail packages, custom widths, reinforced edges, and shipping can change the effective rate. Thermal curtain fabric is a higher-cost product, commonly $0.80-$4.00 per square foot before a tracking system or installation.
A 10-by-20-foot greenhouse may need roughly 500-700 square feet of covering material. The final quantity depends on roof shape, sidewalls, overlaps, door openings, and how the fabric attaches. At $0.25 per square foot, 600 square feet of standard film costs about $150 before accessories; a heavier UV-stabilized film at $0.45 per square foot would cost about $270. Allow extra material for fitting and future patching.
Roll prices are difficult to compare unless the roll width and length are known. A 20-by-100-foot roll contains 2,000 square feet, so a $500 roll works out to $0.25 per square foot. Some suppliers quote by linear foot, especially for fixed-width shade cloth. Divide the price per linear foot by the fabric width to estimate a square-foot rate.
Assumptions: U.S. retail pricing for standard agricultural or horticultural grades; shipping, taxes, and installation are generally excluded.
What film, mesh, and hardware add to a greenhouse quote
A fabric quote can include more than the cover itself. Removal of an old covering, mounting channels, wiggle wire, clips, seam tape, fasteners, lift equipment, and disposal all affect the total. For a small replacement, hardware may be a modest add-on; on a larger structure, new attachment channels or difficult access can add hundreds or thousands of dollars.
| Quote item | Typical price | Unit or scope | What changes the charge |
|---|---|---|---|
| Poly film | $0.10-$0.60 | Per sq ft | Thickness, layers, UV warranty, width |
| Shade cloth or netting | $0.15-$1.60 | Per sq ft | Shade percentage, mesh, borders |
| Channels and attachment wire | $1-$4 | Per linear ft | Material, existing channel condition |
| Installation labor | $50-$100 | Per worker-hour | Roof access, crew size, tensioning |
| Old cover removal and disposal | $100-$700 | Per project | Area, material condition, disposal distance |
| Delivery or freight | $25-$300 | Per order | Roll length, weight, shipping distance |
Labor can be estimated as . A two-person crew working six hours at $70 per worker-hour costs about $840 in labor before a service minimum or travel charge. Quotes should state whether the rate applies per worker or per crew-hour, as those billing methods can differ substantially.
Ask whether the quote includes removal, attachment hardware, freight, and taxes. A low material rate may not represent the installed price, and a quote that includes replacement channels is not directly comparable with a fabric-only price.
How mesh size, shade percentage, and film thickness change price
Material specifications explain much of the price spread. Greenhouse film is often sold in thicknesses such as 4 mil, 6 mil, or 8 mil. A basic 4-mil film may fall near $0.10-$0.30 per square foot, while stronger 6-mil or 8-mil UV-stabilized film can run about $0.25-$0.60. A double-layer system uses more material and may require an inflation blower, so its full system price is not just twice the film rate.
Shade cloth is commonly labeled by shade percentage, such as 30%, 50%, or 70%. Higher shade levels can cost more, but construction and edge treatment matter too. Standard knitted cloth may cost $0.20-$0.90 per square foot; reinforced or custom-finished cloth can reach $1.50. Choosing an unnecessarily high shade rating can reduce light without delivering a useful budget advantage.
For insect netting, mesh opening and pest target are key. A coarser 20-mesh net may cost around $0.15-$0.50 per square foot, while finer 40- to 50-mesh material can reach $0.50-$1.60. The fine mesh may also restrict airflow more, which could require a separate ventilation adjustment. Compare the actual mesh specification, not just product names such as “insect screen.”
Specify thickness, UV protection, mesh count, and shade percentage in writing. These details make competing quotes easier to compare and reduce the chance of receiving a lower-grade substitute. Warranty length alone does not guarantee equivalent performance; check exclusions for wind, abrasion, chemical exposure, and installation method.
Which greenhouse fabric suits a roof, sidewall, or vent
Polyethylene film is commonly used as a full roof and sidewall covering because it is lightweight and comparatively inexpensive. Shade cloth is often installed over a roof or attached externally during hot periods. Insect netting is more commonly used on vents, doors, or sidewalls where pest exclusion is needed. Thermal curtains are typically installed inside commercial structures, where the fabric may open and close over growing areas.
For a small hobby greenhouse, film may be the least expensive choice when the structure is designed for it and the existing channels are sound. Shade cloth can be a lower-cost seasonal addition instead of replacing the main cover, but its shading effect should match the crop and climate. Netting is a targeted alternative to covering every surface with fine mesh, especially when only vents require pest protection.
Thermal curtains involve a different budget calculation. Fabric may cost $0.80-$4.00 per square foot, while tracks, cables, drive motors, controls, and installation can bring a system to roughly $3-$12 per square foot of covered area. A simple manual curtain and a motorized system for a large greenhouse are not comparable bids.
Match the fabric to the structure and the specific job it must do. A material that is cheaper per square foot can cost more overall if it needs custom fastening, blocks too much airflow, or must be replaced sooner in the local conditions.
How greenhouse fabric area and roof shape affect labor
Installation labor usually ranges from $50-$100 per worker-hour, with local contractor rates, minimum charges, and travel time affecting the invoice. A straightforward small greenhouse cover may take a two-person crew 4-8 hours, for about $400-$1,600 in labor. A larger structure with high peaks, multiple bays, or a curtain mechanism can require several workers and one or more days.
Area is only one measure of difficulty. A 500-square-foot cover at ground level may be easier to install than the same area on a steep, tall roof. Wind exposure, overhead obstructions, brittle channels, and the need to keep the greenhouse weather-tight while changing the cover can slow work. Contractors may also require calm weather for safe and even tensioning of wide film sheets.
Measure every roof slope and wall, not just the greenhouse footprint. A 20-by-30-foot footprint is 600 square feet, but a peaked roof and full-height sidewalls can require well over 1,000 square feet of covering. A site visit or a scaled drawing helps prevent shortages and costly rush orders.
Why delivery and local supply change fabric prices
Greenhouse fabric prices vary by market and distribution method. In areas with many agricultural suppliers and nearby manufacturers, common roll sizes may cost 5%-15% less than in remote markets. Rural delivery, oversized freight, and limited local stock can add 10%-25% to the delivered material cost. These are planning comparisons, not fixed regional surcharges.
Online prices may look lower before freight is added. Long rolls can incur oversize shipping charges, and some suppliers require a freight quote rather than showing a standard checkout rate. Local pickup can avoid that fee, although a roll may need a vehicle or trailer large enough to transport it without damage.
Availability can also affect price. Standard widths and colors are usually less expensive than custom widths, special colors, or short production runs. A nonstandard roll may incur cutting fees or leave more unusable offcuts. Check whether the supplier charges for a full roll even when the project needs only part of it.
Compare delivered cost per usable square foot, not the listed roll price. Include freight, minimum order size, cutting charges, and expected waste in the comparison. A slightly higher local price may be cheaper once shipping and the risk of ordering an incorrect width are included.
How to lower a greenhouse fabric bill without underbuying
Accurate measurement is one of the most reliable ways to control cost. Sketch each roof panel and wall, record widths and lengths, and confirm whether the supplier counts usable width after hems or selvage. Add a reasonable allowance for overlap and fastening, but avoid ordering a full extra roll without checking whether smaller cut lengths are available.
Keep a sound attachment system when possible. Reusing clean, straight channels can avoid $1-$4 per linear foot for replacement parts, but corroded or bent channels may damage new film. Replace only failed sections if compatible parts are available. Include the condition of channels in the estimate instead of automatically approving a full replacement.
Choose the specification based on growing needs and exposure. A 50% shade cloth does not always justify the added price of a heavier 70% cloth, and fine insect mesh is unnecessary where pest pressure is low. For a film replacement, compare warranties and thickness rather than paying extra for features that do not address the site’s actual wear risks.
Get at least three itemized quotes using the same measurements and fabric specifications. Ask each installer to separate material, labor, removal, hardware, delivery, and tax. Schedule non-emergency work before peak seasonal demand when practical, and confirm whether the contractor charges a minimum visit fee.
What replacement life means for five-year fabric spending
A low purchase price may not be the lowest long-term cost. Greenhouse film exposed to strong sunlight, wind, or chemical vapors may need replacement more often than film in a protected location. Suppliers commonly offer UV warranties of several years, but warranty terms vary and may not cover installation errors, storm damage, or abrasion against the frame.
For a simple comparison, assume 600 square feet of film costs $180 at $0.30 per square foot and lasts four years. Material spending over five years could be about $360 if a second purchase is needed, before labor and disposal. A $300 film option lasting six years would cost less in material over that period, but only if its expected service life and warranty are meaningful for the site.
Shade cloth and insect netting can often be inspected and repaired in place if tears are small and the edges remain secure. Thermal curtains have additional moving parts, so tracks and motors may need service even when the fabric remains usable. Include accessible spare material, patch products, and replacement hardware in maintenance planning where downtime would be costly.
Compare expected replacement timing alongside the initial price. Ask for the warranty duration, covered failures, installation requirements, and repair options. A modestly higher fabric price can be economical when it avoids repeated labor, freight, or crop disruption.
