Return on Investment:
Typical investment for this size cover: £400-£650 depending on customization Payback period: 2-4 months based on your pool’s larger surface area
After less than half a season, this cover pays for itself. Every year after that is pure savings.
🌡️ Why Sol+Guard 500M 180 is Different: Enhanced UV Protection for Hot Climates
The 180 Formulation Advantage
Standard pool covers work fine in temperate climates (UK, Northern Europe). But in regions with intense UV exposure—Mediterranean countries, Middle East, Southern US, Australia—ordinary covers degrade within 2-3 years.
Sol+Guard 500M 180 is specifically formulated for UV zones up to 180 kLys/yrs, making it ideal for:
✅ Southern Europe (Spain, Portugal, Greece, Southern Italy) ✅ Middle East (UAE, Saudi Arabia, Israel, Turkey) ✅ North Africa (Morocco, Tunisia, Egypt) ✅ Southern US (Florida, Texas, Arizona, California) ✅ Australia & New Zealand ✅ South America (Brazil, Argentina)
View the Global UV Protection Map to see if your region requires 180-rated protection.
What Makes 180 Formulation Superior:
Advanced UV Stabilizers: Enhanced additive package provides 40% more UV resistance than standard 140-rated covers Extended Lifespan: 6-8 years in high-UV climates vs. 2-3 years for unprotected bubble covers Consistent Performance: Maintains solar transmission efficiency throughout lifespan—doesn’t cloud or become brittle Heat Resistance: Rated for pool water temperatures up to 29°C without warranty void
☀️ How Sol+Guard 500M 180 Transforms Your Pool into a Solar Heater
The Science of Maximum Solar Gain
Sol+Guard 500M 180 uses two-ply translucent technology specifically designed to let the sun do what it does best: heat water.
Clear Top Surface: Allows 80% of solar energy to penetrate (vs. 40-60% for blue/silver covers) Translucent Tinted Underside: Optimizes heat transfer directly into water molecules GeoBubble Air Cells: 50% thicker than traditional bubbles, creating an insulative barrier
University-tested results: Pools covered with Sol+Guard showed temperature increases of 6-8°C compared to uncovered pools in identical conditions.
Real-World Temperature Performance:
| Starting Water Temp | After 5 Days Uncovered | After 5 Days with Sol+Guard 180 | Temperature Gain |
|---|---|---|---|
| 18°C (morning) | 19-20°C | 24-26°C | +5-6°C |
| 22°C (pre-heated) | 23°C | 28-30°C | +6-7°C |
| 26°C (warm pool) | 26-27°C | 32-34°C | +7-8°C |
*Based on 6-8 hours daily sun exposure, May-September conditions in Mediterranean climate. Individual results vary based on ambient temperature, wind, humidity, and pool depth.
💧 The Hidden Cost Most Pool Owners Ignore: Water Evaporation
32,000 litres of water per year. That’s what an average uncovered pool (4m x 8m) loses to evaporation. Your 20ft x 40ft pool? Approximately 73,600 litres annually—equivalent to 960 baths or £324 worth of water.
How Evaporation Destroys Your Budget:
Water Loss: 73,600L @ £4.40/m³ = £324/year (your pool size) Evaporative Cooling Effect: Each litre that evaporates steals 2,260 kJ of thermal energy from your pool Chemical Imbalance: Evaporation concentrates dissolved solids, requiring frequent rebalancing Increased Heating: You’re literally heating water that disappears into the air
Sol+Guard 500M 180 eliminates 98% of evaporation, acting as a physical barrier between your pool water and the atmosphere. That’s 72,128 litres retained annually—enough to fill your pool 1.2 times over.
🛡️ GeoBubble Technology: Why This Cover Lasts 25% Longer
Traditional bubble covers were designed for packaging materials, not harsh pool environments. They fail at the stress points where bubbles connect—resulting in tears, splits, and rapid degradation.
GeoBubble revolutionized this with a patented figure-eight design:
Traditional Bubble vs. GeoBubble:
| Feature | Traditional Round Bubble | GeoBubble Figure-Eight |
|---|---|---|
| Stress Points | Sharp corners at connection points | Smooth, radiused waistline—no stress points |
| Material Thickness | Thin points where bubbles join | 50% thicker uniform thickness throughout |
| Thermal Expansion | Limited air expansion space = splitting | Greater room for air expansion |
| Lifespan in UV exposure | 2-3 years (becomes brittle) | 6-8 years with 180 formulation |
| UV Protection | Basic stabilizers | Advanced additive, stabilizer & anti-oxidant package |
The result: GeoBubble covers last 25% longer than traditional designs even before factoring in the enhanced 180 UV formulation. With the 180 additive package, you’re looking at double the lifespan in high-UV regions.
⚡ Energy Savings That Actually Matter
Heating a pool is expensive. Without a cover, you’re burning through electricity (or gas) at an alarming rate.
Head-to-Head Energy Consumption Test:
30-day university trial, identical pools (4m x 8m):
Pool with Sol+Guard: 50.5 kWh consumed Uncovered pool: 393.3 kWh consumed Energy savings: 87%
What This Means for Your 20ft x 40ft Pool:
Scaling to your pool size (~74m² surface area vs. 32m² reference pool = 2.3x larger):
Without cover: Approximately 904 kWh/month = £253/month @ £0.28/kWh With Sol+Guard 500M 180: Approximately 116 kWh/month = £32/month @ £0.28/kWh
Monthly savings: £221 Annual savings (6-month season): £1,326
Over the 6-8 year lifespan of this cover, you’re looking at £7,956-£10,608 in avoided heating costs for an initial investment under £650.
🧪 Chemical Savings: The Bonus You Didn’t Expect
When your pool is covered, everything stays balanced longer.
Why Sol+Guard 500M 180 reduces chemical consumption by up to 30%:
Prevents UV Degradation: Chlorine breaks down under sunlight—the translucent design lets heat through while the cover itself blocks direct UV assault on chemicals Eliminates Debris: No organic matter falling in = no chlorine wasted breaking down leaves, insects, dirt Stops Evaporation: Concentrated chemicals from water loss? Not anymore Stable pH: Less evaporation = less frequent pH fluctuations = fewer adjustments
Annual chemical savings for your pool size:
- Chlorine: Up to 11.5kg savings ≈ £70
- pH adjusters: ≈ £25
- Algaecides: ≈ £20 (when combined with proper filtration)
Total: £115/year in chemicals you don’t buy, plus reduced labor for testing and balancing.

📏 Perfect Fit: Made-to-Order for Your 20ft x 40ft Pool
This cover is manufactured specifically to 20ft x 40ft dimensions (approximately 6.1m x 12.2m), ensuring:
✅ Complete surface coverage – no gaps for heat loss or evaporation ✅ Proper fit with roller systems – no excess material dragging in water ✅ Optimal performance – every square metre working efficiently
Can’t find your exact pool size? Parts4Tubs offers custom sizing through their solar cover calculator for non-standard pool shapes and dimensions.
Installation: Bubbles Down, Smooth Side Up
Critical installation rule: Place the cover with bubbles facing DOWN into the water, smooth translucent surface facing UP toward the sun.
Why this matters:
- Air trapped in bubbles is heated by transmitted solar energy
- Heated air transfers thermal energy directly to water below
- Smooth top surface maximizes solar transmission
- Incorrect installation (bubbles up) reduces effectiveness by 30-40%
Recommended accessory: A pool roller system makes daily cover placement and removal effortless, especially for this 800 sq ft (74m²) cover size.

❓ Frequently Asked Questions
Q: Will this cover heat my pool on its own, or do I still need a heater?
A: Sol+Guard 500M 180 is a solar enhancement system, not a complete heating solution. In optimal conditions (6-8 hours sun, Mediterranean climate), it can raise water temperature 6-8°C through free solar energy. However, for consistent swimming temperatures, you’ll still need a primary heat source (heat pump, gas heater, or solar panels).
The magic happens when you combine them: Your heat pump or heater brings the pool to your target temperature, then Sol+Guard 180 maintains it while adding free solar gains—reducing your heater runtime by 70%. Best of both worlds.
Q: How does the 180 formulation differ from standard Sol+Guard?
A: Both covers use identical GeoBubble technology and translucent two-ply design. The 180 formulation contains enhanced UV stabilizers specifically for regions with intense UV exposure (up to 180 kLys/yrs vs. 140 kLys/yrs for standard).
In practical terms: If you live in Spain, UAE, Florida, or Australia, the 180 formulation will last 6-8 years. The standard 140 formulation in those same climates might only last 3-4 years before becoming brittle. For temperate climates (UK, Northern Europe), either formulation works—180 simply provides extra insurance.
Check the UV Protection Map PDF to see which formulation your region requires.
Q: Can I leave the cover on while running my pool pump and filter?
A: Yes, absolutely. Sol+Guard 500M 180 is designed to remain in place during filtration. The cover floats on the surface and doesn’t obstruct skimmers, returns, or circulation. In fact, covering during filtration helps:
- Reduce pump runtime (cleaner water = less filtration needed)
- Maintain temperature while filtering
- Prevent debris contamination during circulation
Just ensure the cover is properly secured so it doesn’t get pulled into the skimmer. Many pool owners use cover rollers to partially retract the cover near the skimmer area if needed.
Q: What’s the warranty, and what voids it?
A: Sol+Guard 500M 180 comes with a 6-year pro-rata warranty (UK & Ireland):
Warranty covers:
- Material defects
- GeoBubble delamination
- UV degradation beyond expected parameters
Warranty void conditions:
- Water temperature exceeds 29°C consistently
- Chemical levels exceed SPATA standards (especially chlorine >5ppm or pH >8.0)
- Improper storage (exposed to direct sun when off pool)
- Physical damage from sharp objects or improper handling
Pro tip: Store your cover in the shade using the included protective sheet when not in use, especially in high-UV climates. This extends lifespan beyond the warranty period.
Q: Will this cover prevent algae growth?
A: Sol+Guard 500M 180 reduces algae growth but isn’t specifically designed for algae prevention like Energy Guard Selective Transmission.
How it helps:
- Blocks debris (organic matter feeds algae)
- Reduces evaporation (stable chemistry = less algae opportunity)
- Creates barrier against airborne spores
However: The translucent design allows 80% of solar spectrum through, including wavelengths algae use for photosynthesis. If algae is a recurring problem in your pool, consider Energy Guard 500M instead—it uses selective transmission to block algae-feeding wavelengths while still allowing heat gain.
Current algae situation OK? Stick with Sol+Guard 180 for maximum solar heating.
Q: How much does this 20ft x 40ft cover weigh? Can I handle it alone?
A: Sol+Guard 500M 180 at this size weighs approximately 18-22 kg (40-48 lbs) dry. It’s manageable for one person but significantly easier with two people or a roller system.
We strongly recommend a pool roller for covers this large (800 sq ft / 74m²). Benefits:
- Effortless daily placement and removal (30 seconds vs. 5+ minutes)
- Prevents dragging cover on deck (extends lifespan)
- Enables one-person operation
- Protects cover from damage during handling
Parts4Tubs offers compatible roller systems designed specifically for covers this size.
Q: Can I use this cover in winter, or do I need a separate winter cover?
A: Sol+Guard is a summer/swimming season cover only. When closing your pool for winter (typically October-March in the UK), switch to a purpose-built winter cover.
Why Sol+Guard 180 isn’t suitable for winter:
- GeoBubble design isn’t load-rated for snow or ice accumulation
- Freezing temperatures can damage bubble structure
- No perimeter securing system for harsh weather
Proper seasonal rotation:
- April-September: Use Sol+Guard 500M 180 for solar heating and heat retention
- October-March: Switch to mesh winter cover for debris protection and weatherproofing
- Off-season storage: Store Sol+Guard in protective sheet, away from direct UV
Following this protocol ensures your Sol+Guard 180 delivers its full 6-8 year lifespan.
Q: Does the translucent design mean I can see debris in the pool?
A: Yes, and that’s actually a benefit. Unlike opaque covers (blue, gold, black), Sol+Guard’s translucent design lets you monitor water clarity and spot any debris that sneaks in before uncovering.
Advantages:
- Visual inspection without removing cover
- Early detection of water quality issues
- Aesthetic appeal (many pool owners prefer seeing their pool)
Downside:
- You’ll notice if water isn’t crystal clear (but you’d want to know this anyway)
If aesthetics are a concern and you prefer an opaque cover that hides the pool, consider Gold 500M or Gold 600M instead—though you’ll sacrifice some solar gain efficiency.
Q: How long does delivery take for a made-to-order cover?
A: Sol+Guard 500M 180 covers are manufactured to order:
Lead time: Approximately 14-21 working days from order confirmation Delivery: FREE UK delivery on orders over £50 (this cover qualifies) Bespoke sizing: May add 3-5 additional days for non-standard dimensions
Why made-to-order? Each cover is precisely cut to your pool dimensions, ensuring perfect fit and eliminating wasteful inventory. The wait is worth it for a cover engineered specifically for your pool.
Order early: If you’re planning for the upcoming swim season, order 4-6 weeks in advance to ensure arrival before you need it.

Savings Calculations Methodology
All financial projections on this page are estimates based on the following assumptions:
Reference Pool: 4m x 8m (32m²), 1.5m average depth, 48m³ volume Your Pool (20ft x 40ft): Approximately 6.1m x 12.2m (74m²), scaling factor of 2.3x for costs UK Energy Rate: £0.28/kWh (November 2025 average; your rate may differ) UK Water Rate: £4.40/m³ (regional average; your rate may differ) Swimming Season: 6 months (April-September) Climate: Temperate to Mediterranean with 6+ hours sun exposure daily Heating System: Modern heat pump (COP 5.0) or equivalent Cover Usage: 70% of time during swimming season (nights + when pool not in use)
Your actual savings will vary based on:
- Geographic location and local utility rates
- Pool dimensions, depth, and volume
- Actual sun exposure hours and weather patterns
- Heating system efficiency and type
- How consistently you use the cover
- Wind exposure (increases evaporation when uncovered)
- Ambient temperature and humidity
- Water temperature targets (higher targets = more heating cost)
These are NOT guarantees—they are realistic estimates based on university research and customer data. Track your own results for 3-6 months to see your specific savings.
Temperature Performance Factors
“Up to 8°C temperature gain” depends on:
Optimal conditions (6-8°C gain):
- 6+ hours direct sunlight daily
- Mediterranean or hotter climate
- Low wind conditions
- Cover used 90%+ of time
- Dark-colored pool basin (absorbs more solar energy)
- Shallow pool depth (1.0-1.5m)
Reduced performance (3-5°C gain):
- 3-5 hours sun exposure daily
- Temperate climate (UK, Northern Europe)
- Moderate wind exposure
- Lighter-colored pool basin
- Deeper pools (1.8m+)
Minimal performance (<3°C gain):
- Heavy shade or frequent cloud cover
- High wind exposure
- Intermittent cover use
- Very deep pools (2.5m+)
Sol+Guard 180 maximizes solar gain in ANY conditions, but environmental factors determine the absolute temperature increase. Even in suboptimal conditions, you’ll still benefit from 98% evaporation reduction and 75% heat retention.
UV Protection Rating Explanation
180 kLys/yrs means this cover is formulated for regions receiving up to 180 kilolangley-years of cumulative UV exposure.
Check your region:
- ≤140 kLys/yrs: UK, Ireland, Northern Europe, Northern US, Canada, New Zealand
- 140-180 kLys/yrs: Southern Europe, Southern US, Middle East, Australia, North Africa, South America
Download the UV Protection Map PDF to confirm your zone. If your region is ≤140 kLys/yrs, standard Sol+Guard 140 formulation may suffice (though 180 provides extra insurance).

Safety Warnings
CRITICAL: Sol+Guard 500M 180 is NOT a safety cover and cannot support weight.
❌ Will NOT support a child, adult, or pet walking on it ❌ Will NOT prevent drowning or unauthorized pool access ❌ Is NOT a substitute for proper pool fencing or alarms
If child safety is a concern, install a perimeter fence meeting local safety codes AND consider a dedicated safety cover with track system in addition to (not instead of) your solar cover.
Never leave pool unattended without proper safety barriers, regardless of cover type.
Performance Reality Check
We’re committed to transparency. Here’s what Sol+Guard 500M 180 will NOT do:
❌ Completely eliminate your heating costs (reduces by 50-70%, not 100%) ❌ Heat a heavily shaded pool to comfortable swim temperatures ❌ Prevent all algae growth (reduces risk, but chemistry still matters) ❌ Last forever (6-8 years with proper care in high-UV climates) ❌ Work effectively if left off the pool most of the time ❌ Protect pool in winter (use dedicated winter cover)
What it WILL do: ✅ Maximize free solar heating better than any other bubble cover ✅ Eliminate 98% of water evaporation ✅ Reduce heating costs by 50-70% when used consistently ✅ Last 25% longer than traditional bubble covers (even more with 180 UV protection) ✅ Pay for itself within 2-4 months for most pool owners ✅ Save you thousands of pounds over its 6-8 year lifespan
This is a proven, research-backed product—but it’s not magic. It requires consistent use and reasonable expectations to deliver its impressive benefits.
