Benefits of External Wall Insulation

Benefits of External Wall Insulation

The most significant heat loss in your home is through the external walls. This is estimated to be around 45% of the total heat loss, resulting in high heating bills. By insulating your external walls, you can reduce heat loss and significantly cut your heating bills.

Your home will warm up more quickly if insulated and you won’t have to keep the heating on for as long to reach a comfortable temperature. Condensation will be a thing of the past and without it less mould growth will occur, leading to a healthier living environment.

With the installation of external wall insulation your home will be transformed with a wide range of contemporary or traditional finishes with a choice of textures, colours and finished effects.

The high performance render finishes used on the system offer excellent durability and protection against rain, UV rays from sunlight and cracking. Our finishes have the colour pigments added during the mixing process which means they never have to be painted, providing you with a low maintenance home.

With a transformation in its appearance and increased thermal performance the value of your home could increase.

High levels of heat loss also result in a high carbon footprint, by reducing these levels through insulation you will not only be saving money but helping to protect the environment by reducing carbon emissions.

If you own a house without a cavity in the walls, improving its thermal performance means insulating either internally or externally. Using external wall insulation has the following advantages:

No internal living space is lost as all the insulation is on the outside walls.
No need to vacate the house whilst works takes place and no need to move furniture and fittings.
No internal redecoration is required, particularly kitchens and bathrooms.
Thicker or higher performing insulation can be used resulting in warmer walls.
The risk of condensation and cold- bridging is eliminated as the whole building is wrapped in insulation.
An exterior finish is developed which can often closely match the original or surrounding properties.

Damp problems? Here”s how they are caused

Causes of damp – Leaks

Leaks can often be a major cause of damp within a property leading to issues such as penetrating damp and wet rot. Generally, the result of a leak will be localised to one area of a wall. If you notice localised damp patches, check the following:

Examine downpipes and gutters within the affected area.
Look for damage, cracks, faulty joints or seals.
Ensure that your drains and downpipes are not blocked. Rain water can very easily be backed up forcing itself out of a pipe joint within the affected area.
If the damp is below a flat roof, or a roof channel, check that the felt is sound.
If the damp is below a window, check the window frame and window sill. Badly fitted windows can also let damp penetrate into a room
If the damp is localised around a chimney breast, check the flashing and tiles

Causes of damp – rising damp

Causes of damp – rising dampIf you are on the ground floor and the damp seems to be at the bottom of walls, it could be that the cause of damp is the result of your damp proof course being bridged resulting in rising damp. This could be because of an increase of ground levels around the affected damp area or that your damp proof course has failed.

If it is the case whereby the damp proof course has been bridged, consider if there is any external features installed within the affected area such as a flower bed or new patio. Could there be an excess amount of soil against the wall from some recent gardening that has bridged the damp proof course? By simply lowering the ground level or removing any of these features and leaving the area to dry out, you could solve your rising damp issue.

If it is the case the damp proof course has not been bridged, then it could be the possibility that your damp proof course has failed meaning that you will need to consider repairing it. In this instance, we would always recommend you contact a damp professional to organise a property survey to fully evaluate the extent of the damp issue.
Causes of damp – condensation

Cause of damp – condensation
It is not always the case whereby the cause of damp originates from the outside. One of the most common causes of damp within homes is due to condensation.

Condensation occurs when large quantities of water vapour from general everyday living becomes trapped within a property. When the warm moist damp air comes into contact with cooler air, or a surface which is at a lower temperature, the result is condensation, this can prove ideal for the germination of the commonly associated black mould.

The key to solving condensation however is ventilation. By simply improving the air ventilation within a property, you will generally have an impact on the amount of condensation and mould issues that you are having within a property. To find out more, visit our how to prevent condensation web page.
