What is balcony insulation and why do I need it?  

Balcony insulation is made up of two parts: an inner layer and an outer layer. The inner layer is made of foam or other material that helps to insulate the space between the two layers. The outer layer is typically made of metal or other material that helps to reflect heat.  

Balcony insulation is a great way to keep your balcony warm and comfortable in the colder months so you can use it all year around. It also helps to regulate temperature and keep you cool in the warmer months too. Insulation for balconies also helps you cut down on energy, as you can both save money and reduce your environmental impact. 

The benefits of insulating a balcony: 

When looking for ways to insulate a balcony, it’s important to consider the benefits of a balcony to ensure you make an informed choice. The benefits of balcony insulation include:  

  • Keep warm during the cooler months 
  • Keep cool during warmer months 
  • Reduce energy bills  
  • Reduce greenhouse gas emissions  


Choosing the right material for insulating a balcony: 

When choosing an insulating material for your balcony, it is important to consider its R-value, which is its ability to resist heat transfer. The higher the R-value, the better the material will be at insulating your space.  

Another important consideration is your climate and if your balcony needs weatherproofing. If you experience harsh winters or very wet weather, you will need a material that can stand up to the cold and wet to keep your balcony comfortable all year round.  

The best insulating material for balconies is most often quite thin, as it needs to fit below the doorway to get beneath the flooring, without adding any additional weight that could destabilise the foundation.

Step 1:  

First, you need to measure the area of your balcony to determine how much insulation material you will need. Make sure to measure the length and width of your balcony so that you can calculate the surface area. 

Step 2:  

Once you have determined the exact size of the area, measure your boards in alignment with the dimensions needed. Cut your boards into pieces that are slightly smaller than each individual panel in your balcony. This will allow for better coverage and prevent any gaps between each board.   

Step 3:  

Place the pieces in their respective positions and secure them with screws or nails as needed. Stainless steel screws are ideal for maximum durability. 

Step 4:  

After securing all of the pieces, add some caulking around each panel to ensure proper air sealing and insulation retention. Take care when applying the caulk so that it does not interfere with the placement of any boards or cause damage to any panels.  

Step 5:  

To finish up, cover up all of the exposed edges with tape for extra protection against moisture and water infiltration.
