Solid wall insulation can be applied externally or internally to a solid walled house to reduce heat loss; a combination of the two is also common – it all depends on the building.
But which is best?
This is a question where there isn’t a simple answer. Both have positives and negatives.
External Wall Insulation
√ Reduces heat Loss
√ Reduces fuel Bills
√ Increases warmth
√ Dramatically improves appearance
√ Reduces maintenance required on the exterior of the building
√ Extends lifespan of the building
√ Does not affect the inside of the property
× The installation process in weather dependant
Internal Wall Insulation
√ Reduces heat Loss
√ Reduces fuel Bills
√ Increases warmth
√ Doesn’t change the appearance of a property which has character features
√ Can be installed regardless of weather
× Doesn’t protect the building resulting maintenance still being required
× Reduces internal living space
× Causes major internal disruption and requires re – decorating and re – fixing of carpets
× Plug sockets and radiators have to be relocated
As you can see the aim of reducing heat loss, saving money and becoming more environmentally friendly is achieved through both types of insulation. The end result and the hassle which is gone through are very different.
Internal wall insulation creates a lot of extra work including full re – decoration of each room worked in and all sockets etc removed from the newly insulated wall; not forgetting the reduction in space in the room.
Once you have decided which type of insulation you feel is best for yourself and family, it’s important to research whether the type chosen will be suitable for your property type. It’s great to preserve external features by insulation internally but will this hide any character also? Do you want to spend time after the installation putting your house back together? It definitely needs a lot of thought.
