How Long Does It Take to Install Different Types of Insulation?

Improving your home's energy efficiency is a smart way to create warmer homes and save on heating bills. One of the best ways to achieve this is by installing insulation. But how long does insulation installation take? The answer depends on the type of insulation you choose. This post explores the installation times for internal wall insulation, external wall insulation, and loft insulation, helping you plan your project with confidence.

Internal wall insulation installation

Internal Wall Insulation Installation Time

Internal wall insulation involves fitting insulation materials like Wetherbys Rockwool inside your existing walls. This method is popular for improving energy efficiency in homes where external changes are not possible or desired.

• Typical installation time: 1 to 3 days for an average-sized room

• Factors affecting duration:

  
  

- Room size and number of walls to insulate

- Condition of existing walls (e.g., need for repairs)

- Complexity of electrical outlets and plumbing that may require adjustments

The process includes removing existing wall coverings, fitting the insulation panels, and then re-plastering or covering the walls. While it may cause some disruption, internal wall insulation is relatively quick and effective at reducing heat loss.

External Wall Insulation Installation Time

External wall insulation installation

External wall insulation uses materials like EPS (expanded polystyrene) or Rockwool applied to the outside of your home. This method is excellent for significantly improving energy efficiency and creating a continuous insulation layer.

• Typical installation time: 5 to 10 days for a standard detached house

• Factors affecting duration:

- Size and height of the property

- Type of external finish (render, brick slips, cladding)

- Weather conditions during installation

External wall insulation requires fixing insulation boards to the exterior walls, applying a base coat, and finishing with a protective render or cladding. This process takes longer than internal insulation but offers the benefit of minimal disruption inside the home and better thermal performance.

Loft Insulation Installation Time

Loft insulation installation

Loft insulation is one of the quickest ways to improve your home's warmth and reduce heating bills. Using materials like Knauf Earthwool, loft insulation can be installed either by laying rolls or blowing loose-fill insulation.

• Typical installation time: 2 to 6 hours for an average loft

• Factors affecting duration:

- Loft size and accessibility

- Type of insulation material used

- Existing insulation removal if necessary

Loft insulation installation is straightforward and usually completed in a single day. It is highly effective at reducing heat loss through the roof, which accounts for a significant portion of energy waste in many homes.

What to Expect During Installation

Each type of insulation installation has its own set of preparations and impacts on your daily routine:

• Internal wall insulation may require moving furniture and some dust control due to plastering work.

• External wall insulation involves scaffolding and some noise but keeps your interior largely unaffected.

• Loft insulation requires access to the loft space and may involve some disturbance if old insulation is removed.

  
  

Planning ahead and discussing timelines with your installer will help minimize inconvenience.

Benefits of Installing Insulation

No matter which type you choose, insulation helps to:

• Improve energy efficiency by reducing heat loss

• Create warmer homes that are comfortable year-round

• Save on heating bills by lowering energy consumption

  
  

Investing in insulation pays off quickly through lower energy costs and increased comfort.
