1. Insulation: The #1 Factor for Sunroom Efficiency

Without proper insulation, your sunroom will waste energy and increase bills. Here’s how to fix it:

Double/Triple-Pane Windows (Low-E Glass)

• Best for Dallas: Low-emissivity (Low-E) glass blocks UV rays while keeping heat inside in winter.
• Pro Tip: Argon gas-filled panes add extra insulation.

Thermal Curtains or Shades

• Blocks 50-60% of solar heat in Dallas summers.
• Best Choice: Honeycomb shades (traps air for insulation).

Insulated Roof Panels

• A poorly insulated roof = major heat loss.
• Solution: Use polycarbonate panels or spray foam insulation.

2. Energy-Efficient Glass & Window Types

Not all glass is equal! Here’s what works best in Dallas:

Avoid: Single-pane glass—biggest energy waster!

3. HVAC & Ventilation Tips for Dallas Sunrooms

Mini-Split AC Systems (Most Efficient)

• No ductwork needed (perfect for additions).
• Zoned cooling saves energy.

Ceiling Fans with Reverse Function

• Summer: Pulls hot air up.
• Winter: Pushes warm air down.

Smart Thermostats

• Automatically adjusts temps when the sunroom isn’t in use.

4. Bonus: Low-Cost Energy-Saving Hacks

Install Weatherstripping – Seals gaps in doors/windows.
