What is wall insulation and why do I need it?  

Wall insulation is used to fill the space between the outer walls of a house and the inner living space to regulate temperature. It helps to keep the heat in in the winter and out in the summer, making your living space much more comfortable.  

Wall insulation also helps to reduce your home’s energy consumption, as if it is saving heat, it there will be no need for it to generate any more. This further reduces your carbon footprint, meaning wall insulation is not only cost-effective, but environmentally conscious.  

The benefits of insulating a wall: 

The benefits of insulating a wall include: 

  • Increased energy efficiency  
  • Lower carbon footprint and energy costs  
  • More regulated temperature inside your home 
  • Improved indoor air quality  
  • Protect walls against adverse weather 

Choosing the right material for insulating a wall 

There are a variety of things to consider when choosing the right material for insulating a wall. It is important to consider the R-value of any of your potential choices. This is the material’s ability to resist heat transfer. The higher the R-value, the better the material will be at insulating your space. 

It is also worth considering the size of the wall – or walls – you want to insulate as well as your budget. Recognising these elements will help you decide the insulating material that is best suited to you.

How to install insulation for a wall with KNAUF Insulated Plasterboard:  

DISCLAIMER: This guide acts as a brief outline for wall insulation. Be sure to consult a professional before starting your project. 

Step 1:  

Measure the desired wall(s) to calculate the amount of insulated plasterboard you will need.   

Step 2:  

Cut each individual board to size using a measuring tape and a sharp utility knife or saw. Take great care not to damage the insulation layer when cutting, as this will reduce its effectiveness.  

Step 3:  

Gently lower each board into place on its edge until it sits flush against the wall using firm but gentle pressure. Be sure to allow sufficient space between each sheet for expansion during temperature changes and make sure edges meet up firmly at joints where multiple boards intersect one another. 

Step 4:  

Secure the boards to the wall using appropriate fixings such as drywall screws or drywall nails spaced every 8-12 inches along each side of the board. 

Step 5:  

Finishing touches include adding a sealant around all edges and corners of where walls meet ceilings, floors, window frames, doorways etc., caulking around electrical fittings or fixtures that penetrate through walls, finishing off with sealant again and filling in screw holes with putty or spackle to achieve an even surface finish ready for painting/decorating. 


How should I prepare my walls for insulation? 

If your walls have any old insulation, it is important to remove this before you install the new insulation. You should also inspect the walls and be sure to fill any holes or cracks, as this may interfere with the efficiency of the new insulation. 

What are the benefits of wall insulation?  

The benefits of wall insulation include increased energy efficiency, lower carbon footprint, cheaper energy bills, a more regulated temperature inside the home, improved indoor air quality, and protection for walls against adverse weather.  

How do I choose the right wall insulation for me?
