With rising energy prices and living costs, you may worry about heating your glass extension.
Whether you’re buying a new conservatory or already own one, keeping it cosy and warm in winter without high bills is a common concern.

Energy efficiency in your conservatory depends on two factors:

• The external structure and insulation
• The internal heating system and window treatments

Below are 8 ways to boost your conservatory’s energy efficiency:

1. Energy Efficient Glazing

• The glass is the most important part of your conservatory.
• You must have at least double-glazed glass that traps argon gas between two panes.
• Spend more on high-quality temperature controlled glass to reduce heat loss.
• Choose glass with the lowest U-value for the best performance

2. Roof Insulation

• Heat rises, so the roof is the biggest source of heat loss.
• Use roof glass with advanced temperature control, anti-glare, and UV-blocking features.
• If you already have a conservatory, consider upgrading your roof glass.
• Alternatively, you can opt for a fully insulated tiled roof with skylights to improve both light and insulation

3. Frame material

• Your frame choice affects heat retention.
• Popular options include timber, uPVC, aluminium, and oak.
• Aluminium frames often have a ‘thermal break’ to reduce heat loss.
• uPVC frames paired with double-glazed glass are very energy efficient.
• Choose a frame that suits your style, energy needs, and maintenance preferences.

4. Conservatory Base and Walls

• Ensure all walls (full height or dwarf) meet building standards.
• Include cavity wall insulation.
• The concrete base should have a continuous damp-proof membrane to stop moisture.

5. Internal Doors

• For glass extensions that open into your home, insulation is key.
• A bi-fold door offers an open-plan feel but lets you close off the extension to keep warmth inside.
• Keeping doors closed helps trap heat and saves energy.

6. Window and Door Seal Maintenance

• Regularly check seals, locks, hinges, and hardware.
• Look out for gaps or damage that can allow drafts or water leaks.
• Maintenance before winter helps keep your conservatory energy efficient

7. Heating Installation

• Building regulations require a separate heating system for your conservatory or orangery.Options include:
• Radiators with thermostat control (requires approval and good insulation)
• Electric radiators (cheaper to install but may cost more to run)
• Underfloor heating (more expensive upfront but very efficient in the long run)
• Research which system best suits your design, needs, and budget

8. Blinds or Window Treatments

• Adding blinds or other window treatments creates an extra barrier to retain heat.
• Choose a style that matches your interior design and budget.
• Open them during the day to let sunlight in, and close them in the evening to trap warmth.
• This simple upgrade also reduces glare and adds a cosy feel at night.

Design or Upgrade for Energy-Efficiency

Your conservatory should be enjoyed all year round. With the right glass, insulation, heating, and window treatments, you can keep your space cosy no matter the weather. Invest in quality materials during design or upgrade an existing structure to boost energy efficiency and comfort for years to come.
