  • Fiberglass batts: These are affordable and easy to install, but they may not seal air leaks as effectively.


Types of Insulation Materials

Blown-in cellulose is made from recycled paper products. It’s treated with fire retardants for safety. This material can fill cavities and gaps in walls and attics, providing a good thermal barrier.

Spray foam insulation expands to fill gaps and cracks. It provides excellent air sealing and has a high R-value, meaning it resists heat transfer well. However, it requires professional installation and can be more costly.

Fiberglass batts are a common type of insulation. They’re made from tiny glass fibres and come in pre-cut panels. While they’re easy to install, they may not fit snugly around obstacles like pipes and wiring.

Each of these materials has its pros and cons. It’s important to consider your home’s specific needs and consult with a professional if needed.

Remember, the effectiveness of insulation is not just about the material. Proper installation is crucial to maximize its performance.

Addressing Thermal Bridging

Thermal bridging is a common issue in older homes. It occurs when heat is transferred across more conductive materials in the building envelope.

This can significantly reduce the effectiveness of your insulation. It’s like having a hole in your thermal blanket.

Addressing thermal bridging involves adding a continuous layer of insulation. This can be challenging in older homes, but it’s crucial for improving energy efficiency.

Windows and Doors: Sealing the Gaps

Windows and doors are common areas where older homes lose energy. They often have gaps and cracks that allow heat to escape.

Weatherstripping and caulking are simple, cost-effective ways to seal these gaps. They can significantly reduce drafts and improve your home’s thermal efficiency.

Another strategy is to install storm windows. These add an extra layer of insulation, reducing heat loss through your windows. They can be particularly effective in colder climates.

Remember, even the best insulation can’t fully compensate for poorly sealed windows and doors. So, it’s worth investing time and effort in sealing these gaps.

Upgrading HVAC and Thermostats for Better Efficiency

Older homes often have outdated heating, ventilation, and air conditioning (HVAC) systems. These can be major energy guzzlers. Upgrading to a modern, energy-efficient HVAC system can significantly reduce your energy consumption.

Programmable thermostats are another excellent investment. They allow you to set your home’s temperature for different times of the day. This means you’re not wasting energy heating or cooling your home when no one is there.

Remember, regular maintenance of your HVAC system is crucial. Even the most energy-efficient system can become wasteful if not properly maintained.

In conclusion, upgrading your HVAC system and installing a programmable thermostat can contribute significantly to improving the energy efficiency of your older home.

Energy-Efficient Lighting and Appliances

Switching to energy-efficient lighting is a simple yet effective step. LED bulbs, for instance, use significantly less energy than traditional incandescent bulbs. They also last much longer, reducing the need for frequent replacements.
