Insulation Services: Enhancing Energy Efficiency and Comfort with Cavity Wall, External Wall, Internal Wall, and Loft Insulation

At TF Group we provide a full range of insulation services, including internal wall insulation (IWI), loft insulation, external wall insulation (EWI), and cavity wall insulation (CWI).


All works are delivered by PAS 2030-accredited installers, ensuring compliance with funding schemes, TrustMark requirements, and long-term performance standards. 

Why Insulation Matters:

  • Reduces heat loss, cutting energy bills and carbon emissions. 
  • Improves comfort by eliminating cold spots and draughts. 
  • Essential for achieving PAS 2035 whole-house retrofit compliance. 
  • Provides the foundation for low-carbon heating and renewable technologies to perform effectively. 

Internal Wall Insulation (IWI):

IWI involves adding insulation to the inside of external walls, improving thermal performance without altering the building’s exterior. 

 

Key outcomes: 

  • Suitable for properties where external changes are restricted. 
  • Significant reduction in heat loss through solid walls. 
  • Improves comfort while maintaining the property’s character. 

Loft Insulation:

Insulating the roof space is one of the quickest and most cost-effective upgrades. Loft insulation prevents up to a quarter of heat from escaping through the roof. 

 

Key outcomes: 

  • Lower heating bills with rapid payback. 
  • Warmer rooms beneath the loft space. 
  • Minimal disruption during installation. 

External Wall Insulation (EWI):

EWI adds an insulated layer to the outside of a property, then finishes with a protective render or cladding. It is highly effective for improving the performance of solid wall homes. 

 

Key outcomes: 

  • Major improvements to thermal performance and appearance. 
  • Protection for existing brickwork or masonry. 
  • Increased property value and durability. 

Cavity Wall Insulation (CWI):

CWI fills the gap between external and internal walls with insulation material, reducing heat loss in homes with uninsulated cavities. 

 

Key outcomes: 

  • Quick, cost-effective insulation solution. 
  • Reduced draughts and increased comfort. 
  • Lower carbon footprint and fuel bills. 


Loft Insulation:

Loft insulation is a cost-effective way to enhance energy efficiency and reduce heat loss in your property. Our skilled technicians install high-quality loft insulation materials, creating a barrier that prevents warm air from escaping through the roof. By insulating the loft space, we help maintain a consistent temperature, reduce heating requirements, and improve energy efficiency. Our insulation solutions for lofts are tailored to suit various property types and insulation requirements.

Benefits of Insulation Services:


1.Energy Efficiency: Proper insulation is essential for reducing heat loss and improving energy efficiency. By investing in our insulation services, you can significantly lower your energy consumption and decrease heating costs, leading to long-term savings.


2.Enhanced Comfort: Insulation creates a more comfortable indoor environment by preventing drafts, cold spots, and excessive heat loss. It helps maintain a consistent temperature throughout the property, ensuring a comfortable living or working space all year round.


3.Environmental Sustainability: By improving energy efficiency, insulation contributes to reducing carbon emissions and mitigating the environmental impact of your property. It aligns with sustainability goals and supports a greener and more sustainable future.


4.Noise Reduction: Insulation not only helps with thermal efficiency but also provides soundproofing benefits. It can reduce external noise, ensuring a quieter and more peaceful environment.


5.Property Value: Well-insulated properties are highly sought after in the market. By investing in insulation services, you can increase the value of your property and make it more appealing to potential buyers or tenants.
