Internal Vs External Insulation

Internal Insulation vs External Insulation

If you live in a home where damp spots are a issue and constant heating is required to make the living conditions habitable, it might be time to consider making a couple of home improvements. A cold home is not only uncomfortable to live in but it can also lead to health issues and structural damages to the home if the problem becomes persistent throughout the year. 

Options to help improve your homes levels of heat retention range from installing new double glazed units to converting attic space. While cavity wall insulation may be a  viable option for some homeowners, there are plenty of homes across the country where it isn't practical to install. This is why this blog is solely directed at the benefits of internal and external insulation and which advantages out weigh the advantages of the other for you. 

Internal Insulation

Why Choose Internal?
Insulating your solid and cavity walls can cut your heating bills considerably, because you are losing a substantial amount of heat through your walls. The good news is that they can be insulated from the inside of your home. Correctly installed insulation can reduce heat loss through the fabric of the building, increasing the level of comfort for the homeowner. Internal wall insulation involves fixing a layer of rigid insulation to the inside of external walls, usually with a plasterboard finish. This is also referred to as dry-lining. An ideal opportunity to install internal insulation is when other work is already require. Some electrical/plumbing fittings may need to be removed temporarily for the walls to be insulated but they are re-fitted instantaneously when the insulation works are completed by the Harvest Energy Crew.

Advantages of Internal Insulation

• Dry Lining is quick and easy to install.
• Dry lining is a more cost efficient alternative to external insulation. 
• Internally dry lining walls will save you money in the long term due to up to 30% increase in home heating efficiency. 
• The carbon footprint of your home will be reduced due to the decrease of Co2 emissions being released from the house.
• Eliminates draughts. 
• Prevents frozen pipes.
• Improved B.E.R Rating.
• Reduces noise levels
• Increase in the value of the property. 

Disadvantages of Dry Lining

• Disruption to living arrangements for customers
• Room size reduction

External Wall Insulation

Why Choose External?

External wall insulation provides exterior walls with insulation, finished surface and waterproofing in an integrated composite system. Because walls are areas where the house heat loss is one of the greatest reaching up to 35% of the overall, if they are not properly insulated, this is one of the most effective measures getting your home warmer and greener. External Wall Insulation (EWI) is a composite cladding system comprised of suitable insulation and waterproof coating which is applied to all the external walls of a building. The External Insulation uses the building like a reflector. Due to the heat no longer being able to escape through the outer layer of insulation, it is reflected back into the living areas, creating a constant warm home.

Advantages of External 

• No additional internal space taken up by insulation.
• Inside of the home not disturbed.
• The carbon footprint of your home will be reduced due to the decrease of Co2 emissions being released from the house.
• Eliminates draughts. 
• Prevents frozen pipes.
• Improved B.E.R Rating.
• Increase in the value of the property. 

Disadvantages of External:

• More Expensive than Internal dry lining.
• Generally takes longer to complete than the dry lining process.
