Exterior insulation and cladding protect a building from the external elements such as weather and sound. In recent times it has gained popularity among architects and homeowners. External wall insulation generally has an insulation layer and a protected waterproof finish. Often the exterior insulation is done amalgamating various materials all together to develop strength. Elements used for this purpose can include expanded polystyrene, mineral wool, polyurethane foam or phenolic foam along with cement, mineral to give the best kind of finishing.

Why do we need Exterior Insulation Cladding?
We need exterior insulation cladding to protect the interior and the structure of any building from the damage caused by the following elements –
Water – Moisture can damage the structure of any building. So, to protect it from water, siding is considered to be the most trustable and important cladding element. It is extremely durable too. The membrane, sealant, and flashing protect a building from damaging moisture.
Extreme temperature variations – A building must withstand different weather conditions. Thus, to keep it protected and strong, the exterior cladding can be done. Exterior insulation is a protective layer that protects the structure from the extreme harsh temperature by creating thermal gaps that restricts heat from getting inside the building. To be precise, exterior insulation cladding acts as a bridge between the exterior temperature and interior temperature.
Solar damage – To save our home from the sun rays and ultraviolet rays, cladding has to be done otherwise with proper elements to resist all the harmful effects. Plastic and wood products are not at all apt for this purpose because they tend to degrade easily in the exposure of the sun.
Wind – The areas prone to hurricanes, tornadoes and heavy thunderstorms must be secured with external cladding otherwise the high velocity of wind can damage the structure.
Types of External Insulation Cladding:
If you want to enhance the external look of your house as well as protect the interiors and the structure from the harsh impact of natural forces, then you have to opt for the exterior insulation cladding. Depending on your need and choice, the cost of it might vary. The different types of external wall insulation and cladding are specified here-
Stone walls – Exterior cladding along with wood fibre, cork or lime makes the stone wall damp proof and thus it lasts for a longer period of time. It keeps the interior well ventilated therefore the sign of damp penetration is restricted.
Rigid foam insulations – The outer surface of the brick wall flaking off due to the ravages caused by the weather conditions as well as time is a normal scenario. Therefore, to keep it unbreathable, rigid foam insulations can be used on the external walls.
Cavity-fill insulations along with weatherproofing – Cavity fill insulations are good in some cases but in most of the cases it fails miserably because the rainwater penetrates across the cavity and water keeps entering into the wall. Thus, exterior insulation cladding along with weatherproof render restricts the water dripping into the house.

External wall insulation is expensive but very effective. The external insulation can result in reducing heat loss and saving energy bills, increasing the life of wall, reducing condensation on internal walls and many more. So, if you are thinking about getting exterior insulation cladding done on your walls then go for the best tradesperson available in this field to get the best service. Prior to that gain the planning consent as you will require that at the time of the outset of work.
