How to Create an Energy Efficient Home

How to Create an Energy Efficient Home

Are you wondering why your energy bills are so high? Or maybe you're concerned about the environmental impact of your home's energy consumption? Energy efficiency continues to be a pressing concern, and whether you're an avid DIY enthusiast or an experienced contractor, the quest for a more sustainable and cost-effective home is a shared goal. One of the most impactful ways you can boost your home’s energy efficiency is to upgrade your insulation. In this comprehensive guide, we'll delve into how you can upgrade your insulation in different areas of your home to not only cut utility costs but also reduce your home's carbon footprint. 

The Power of Proper Insulation 

Before we explore insulation upgrades, let's emphasise why insulation is the backbone of energy efficiency: 

  • Energy Savings: A well-insulated home retains conditioned air, reducing the workload on your heating and cooling systems, ultimately saving you money. 
  • Year-Round Comfort: Proper insulation ensures consistent indoor temperatures, keeping you warm in winter and cool in summer. 
  • Reduced Environmental Impact: Lower energy consumption means a smaller carbon footprint, contributing to a more sustainable future. 
  • Increased Home Value: Energy-efficient homes are highly sought after, potentially increasing the resale value of your property. 

Upgrading Loft Insulation 

Your loft is a prime area for upgrading insulation. Here’s how to go about it: 

  1. Assessment: Begin by assessing your current attic insulation. Look for any gaps, signs of wear, or insufficient coverage. 
  2. Material Selection: Choose insulation material with a high R-value suitable for your climate. At Insulation King, our loft insulation includes Superglass Multi Roll, ROCKWOOL Flexi Slab, ROCKWOOL Twin Roll, and more.  
  3. Sealing Air Leaks: Seal any gaps and cracks in the attic to prevent air leakage. Focus on areas around pipes, chimneys, and loft hatches. 
  4. Proper Ventilation: Ensure your attic has proper ventilation to prevent moisture buildup, which can affect insulation performance. 

Upgrading Wall Insulation  

Enhancing wall insulation can be a more involved process, but the benefits are substantial: 

Interior Wall Insulation: 

Interior wall insulation can be a feasible option for homes with accessible interior walls, especially during renovations. Here’s how you can enhance insulation on the inside:   

  • Stud Bays Insulation: If you have cavity walls, you can install the insulation between the wall studs, ensuring that it snugly fits within the cavity. Our cavity wall insulation includes a full range of high-performance options including Thermoblock, 90mm PIR cavity insulation, and many more. You can explore our full range here 
  • Drywall Replacement: If you're already planning on replacing the drywall in a room, it's an ideal time to improve insulation by using higher R-value materials or adding an extra layer of insulation. Check out our insulating plasterboard range to boost the insulation efficiency of your room. 

Exterior Wall Insulation: 

Enhancing exterior wall insulation is a great choice when you’re remodelling your home or applying new siding. This method adds an extra layer of protection on the outside of your walls: 

  • Continuous Insulation: Consider adding a continuous layer of insulation, such as our Polystyrene EPS70 insulation or mineral wool, beneath your new siding. This method helps break thermal bridges and provides an effective insulation barrier. 
  • Advanced Insulation Materials: Explore modern, high-performance insulation materials that offer superior thermal resistance, like our Kingspan Kooltherm thermal insulation. 

Upgrading Floor and Crawl Space Insulation 

When upgrading insulation, it’s also important to consider your floors and crawl spaces: 

  • Subfloor Insulation: Adding insulation to the subfloor above a crawl space can help prevent heat loss. 
  • Crawl Space Encapsulation: If your crawl space is ventilated, consider encapsulating it by sealing vents and installing a vapour barrier. 
  • Insulate Rim Joists: Insulating the rim joists where your home's foundation meets the walls can prevent cold air from entering and warm air from escaping. Explore our floor insulation range to find the ideal products to upgrade your floor insulation.  

Upgrading Windows and Doors Insulation 

Upgrading insulation in windows and doors is crucial for maintaining energy efficiency: 

  • Weatherstripping: Replace worn weatherstripping around doors and windows to seal any gaps. 
  • Caulking: Use caulk to seal gaps and cracks in the window and door frames. 
  • Window Insulation Films: Install window insulation films for an extra layer of thermal protection during the colder months. 

Additional Tips for Energy Efficiency 

  • Use energy-efficient insulation materials: Consider eco-friendly insulation materials such as recycled denim, soy-based foam, or wool, which offer energy-efficient properties. 
  • Upgrade to high-efficiency windows: If you're in need of window replacements, choose double or triple-pane windows with low-E coatings. 
  • Professional vs. DIY: While many insulation upgrades can be DIY projects, don't hesitate to get in touch with professionals like ours for larger, complex projects, ensuring optimal results. 


Upgrading your home's insulation in various key areas is an investment that pays dividends in terms of energy efficiency and lower utility bills. Whether you're a dedicated DIY enthusiast or an experienced contractor, implementing these insulation strategies will not only make your home more comfortable but also contribute to a greener, cost-saving future. So, take the first step towards a more energy-efficient home today, and reap the benefits for years to come.
