What is Façade Insulation – Thermally Insulating Your External Wall?

A major source of heat loss from a house is through walls and facade. Facade insulation plays an important role to provide comfortable and convenient lifestyle in your home. It is essential to improve the energy efficiency of your building. Façade improves the building aesthetic visuals and saves from moisture. It also acts as external insulator to maintain indoor temperature.

ISOVER EPS 70F insulation boards are designed especially for facade insulation. It is largely manufactured by ISOVER Saint-Gobain of the Slovakia, France. These boards are made of polystyrene foam and manufactured using CFC and HCFC-free technologies. Saint-Gobain has been producing high quality insulators through continuous improvement and innovation of manufacturing technologies.

Define facade insulation

Facade insulation is a cladding which thermally insulates your interior, protects your home structure, and provides decorative exterior visuals without adding any structural loadbearing. It protects your interior against heat, cold, noise, and fire. It also protects your exterior wall against the harsh climatic elements. External façade insulations are available in various types based on their design.

The main purpose of facade insulation is to reduce the thermal conductivity with the help of good thermal insulating materials filled into the wall cavities. Significantly, it decreases the energy consumption of your building heating and cooling systems. Installing external façade insulation improves your building’s acoustic, aesthetics, fire safety, and energy efficiency properties.

Best façade insulation materials

The main feature of a best insulating material for facades must have low thermal conductivity and high fire resistance. It must be cheap, energy efficient, and durable.

Some of the best and most commonly used insulating materials for facade insulation are –

  1. Mineral wool – It is made of rock wool or glass wool. Undoubtedly, it is the most widely used materials for thermal insulation because of its sustainable, versatile, and durability characteristics.
  2. Natural cork – Cork has low porosity and is mainly used in construction where thermal and vibration insulations are an important feature of the building.
  3. Polyurethane – This insulating material can be applied by projection or injection. It is an excellent thermal and noise insulator. Polyurethane is easy to handle and install because of its lightweight.
  4. Polystyrene – It is available in two forms, namely the Expanded Polystyrene (EPS) and Extruded Polystyrene (XPS). It is a synthetic and thermal insulating material widely used in facades, walls, floors, and roofs. XPS has more resistance to humidity than EPS.
  5. Cellulose fibre – Being made from recycled paper, cellulose is the most eco-friendly insulation material that can be used for façade insulation. It has a good thermal insulation, fire retardant, insecticide and antifungal properties.

You can choose among the above insulating materials based on your budget and feature requirements. The best façade insulation material must have following characteristics –

  1. Able to eliminate thermal bridges, condensation, and moisture leaks.
  2. Should not affect the interior space of the building.
  3. Easy to repair the cracks in the building envelope.
  4. Thermal shocks absorbent.

Why to insulate the exterior of the facade?

It provides thermal insulation and enhances the aesthetics of your exterior simultaneously. This also makes your building energy efficient. With a wide range of colour and design to choose for your façade material, you can suitable select one to match with your interior.
