External Wall Installations

Efficient home wall installations focus on maximizing thermal performance and energy savings through various insulation methods. Internal wall insulation can be achieved using insulated plasterboard or thermal lining paper, while cavity wall insulation involves injecting insulation into the wall cavity. External wall insulation (EWI) adds an insulating layer to the exterior, enhancing the home’s overall energy efficiency. 

Internal Wall Insulation:

• Insulated Plasterboard:This popular option combines a layer of insulation (like polyurethane foam or polystyrene) with plasterboard, offering easy installation and good thermal performance. 
• Thermal Lining Paper:An affordable and easy-to-install option, thermal lining paper provides a layer of insulation on the wall surface. 
• Stud Wall Insulation:Building a stud wall filled with insulation material like mineral wool can offer another insulation method, but it may slightly reduce room space. 

Cavity Wall Insulation:

• EPS Beading Insulation:This advanced method involves injecting expanded polystyrene beads into the wall cavity, potentially improving the room’s U-value (a measure of heat transfer) significantly, says Home Energy Save. 
• Foam Insulation:Foam, often polyurethane, is another popular cavity wall insulation option known for its thermal properties, though installation may require professional expertise. 
• Insulation Injection:Specialists drill holes in the exterior wall, inject insulation material into the cavity, and then seal the holes, according to Energy Saving Trust. 

External Wall Insulation (EWI):

• EWI Benefits:Adding an insulating layer to the exterior of the house can improve energy efficiency, create a warmer home, and enhance property value, according to YES Energy Solutions. 
• Modern Insulation Materials:Options like open-cell spray foam, which expands to fill gaps and creates an airtight seal, are also used for external wall insulation, says Home Energy Save. 

Considerations:

• Suitability Surveys:Before choosing a particular insulation type, it’s crucial to assess the home’s wall structure and ensure the insulation is suitable to avoid potential damp problems or void formation, says Home Energy Save. 
• Professional Installation:For some insulation types, like foam insulation or EWI, professional installation may be recommended to ensure proper application and performance.
