Understanding PSF in Greenhouse Design: Snow and Wind Load Ratings Explained

1. Choose the right model and shape for your climate

If you live in an area with frequent winds or heavy snowfall, the 10mm Titan or 6mm Virtue models with hinged doors are your best choice. Their peaked, bell-shaped design makes it easy for snow to slide off, minimizing buildup and pressure on the frame.

2. Build on a strong, stable foundation

Set up your ClimaPod on a solid, level foundation — whether concrete, wood, or metal. A sturdy foundation ensures proper alignment, enhances wind resistance, and helps the greenhouse stay secure during extreme conditions.

3. Follow installation steps carefully

During assembly, make sure all bolts are tightened and the frame is firmly anchored to the base. Proper installation and reinforcement are key to maintaining the greenhouse’s durability and long-term stability.

4. Keep distance from other structures

Position your greenhouse at least 6 away from fences, walls, or trees where snow can accumulate or fall. Leaving adequate clearance prevents added pressure from drifting or sliding snow.

5. Secure vents and doors before storms

When strong winds or snow are expected, close and latch all doors and roof vents tightly. For extra protection, install the ClimaPod Storm Kit, which adds additional reinforcements to help your greenhouse withstand severe weather.

6. Monitor weather reports regularly

Stay updated on local forecasts especially during winter months. Taking simple proactive steps before heavy snow arrives can prevent unnecessary strain on the structure and keep your greenhouse safe.

7. Watch conditions closely

Wet, slushy, or icy snow can weigh far more than light powder—over 50 lbs per sq.ft. Most snow-related damage occurs in late fall and early spring, when temperatures fluctuate and create dense snow and ice buildup. If you see accumulation, clear around your greenhouse right away.

8. Remove snow from roof and surroundings promptly

While many ClimaPod owners have reported their 6 mm and 10 mm models withstanding over 5 feet of snow, we recommend clearing snow accumulation once it exceeds 12–18 inches on 6 mm models and 24–30 inches on 10 mm models. If snow removal isn’t immediately possible and a heavy snowfall is expected in a short period, you can place temporary support posts under the main ridge beam to provide extra reinforcement.

• Fresh/fluffy snow: weights about ~3-4 lb/ft³;
• Settled/regular snow: ~12–18 lb/ft³;
• Wet/packed snow: ~22-25 lb/ft³.

After each storm, gently remove snow from the roof with a broom or snow rake, and clear the area around the base. Regular maintenance helps reduce frame stress and keeps your greenhouse strong and reliable throughout the winter season.

9. Add greenhouse to your home insurance

Ask your insurer to list the greenhouse as a covered “other structure” so it’s protected against unforeseen damage (e.g., a tree falling on it); keep photos, receipts, and installation details on file.
