Скачать или смотреть Passive Solar Greenhouse Secrets Revealed: Massive Insulation Blanket in Action Winterizing the Farm

A passive solar greenhouse relies on sunlight as its primary heat source. During winter, insulation blankets act as a thermal shield, preserving daytime heat and preventing nighttime losses. These heavy-duty covers are deployed strategically over glazing, walls, and sometimes interior zones to stabilize temperature without energy consumption.

The Process

1. Thermal Assessment

Identify major heat-loss zones: roof panels, north wall, doors

Measure nighttime temperature drops

Determine insulation thickness based on climate severity

2. Blanket Preparation

Unroll multi-layer insulated blankets (foam-core or quilted reflective types)

Check edges, grommets, and attachment points

Pre-position rollers or guide rails for smooth deployment

3. Daytime Charging

Greenhouse remains fully exposed to sunlight

Soil, water barrels, and internal mass absorb solar heat

Blankets stay retracted to allow maximum solar gain

4. Timed Deployment

As sunlight fades, blankets are pulled or rolled into place

Roof and wall sections are covered first

Seams overlap to eliminate thermal gaps

5. Sealing & Anchoring

Edges are secured with clips, weights, or rails

Air gaps are minimized to stop convection losses

Doors and vents receive secondary insulation layers

6. Nighttime Heat Retention

Trapped warm air circulates slowly inside

Thermal mass releases stored heat gradually

Interior temperature remains stable through the coldest hours

7. Morning Retraction

Blankets are removed at sunrise

Stored condensation is shaken off or drained

System resets for the next solar cycle

Why This Works

Radiant heat reflection keeps warmth inside

Air-layer insulation slows conduction

Thermal mass synergy smooths temperature swings

Key Tips

Automate blanket deployment for consistency

Keep insulation dry to maintain effectiveness

Focus insulation on the north side and roof first
