What Is Wall Insulation?
There are different types of wall insulation. This includes cavity wall insulation, internal wall insulation, and solid wall insulation. Each type of wall insulation offers unique benefits to suit specific property structures and needs. Wall insulation is used to improve energy efficiency and therefore contribute to a greener future. In addition to this, it can save money by reducing energy usage and also provide a more comfortable living space.
Pros of Wall Insulation
- Reduces monthly energy bills by keeping warm air within the property
- Creates a more relaxed space without being too hot in the summer or too cold in the winter
- Wall insulation can be installed using many types of insulation materials and various application methods
- Improves the energy efficiency and sustainability of the building by keeping the warm air within your home
- Insulation will help to meet building regulations and improve safety
- Wall insulation materials can be combined to form an overall system to improve the interior walls
- Internal insulation can help to increase the property value
- Minimises moisture build up when installed properly and prevents structural damage
Cons of Wall Insulation
- The initial materials and installation can be expensive
- Installing insulation may be time consuming and disruptive to the space, particularly when installing internal insulation
- When installed incorrectly, insulation can trap moisture and worsen damp and mould issues
- Older buildings may limit the type of insulation that can be installed, which may need specialist solutions
- Internal wall insulation can reduce the floor space within the room depending on the thickness required
- Some insulation materials can cause irritation to the skin and respiratory system particularly when cut, which can be difficult to manage in your home or office space
- It can take years to notice the payback period of insulation and savings on energy bills
Internal wall insulation
A wide variety of products are available when it comes to insulating internal walls in residential buildings (living space) and commercial buildings (workspace). Internal wall insulation, as the name suggests, targets the inside of the property. When it comes to choosing the right insulation for your property, there is no one size fits all solution. Choosing the right insulation is an important decision and the best option for you will be dependent on a number of factors such as application method, building requirements, your budget, and the wall type in question. With so many options available, you can tailor your insulation to meet your goals both practically and financially.
Benefits of Internal Wall Insulation
- Insulating your internal walls is cheaper than insulating external walls
- Installation methods can vary meaning you can choose which is preferred
- There is a wide range of insulation materials that can be applied internally; therefore, you can choose the product that is required for your type of building
- Internal wall insulation can be installed specifically for what you need such as reduced sound, fire protection, thermal quality or moisture resistance
- Regulates the temperatures from room to room without warm air seeping in and out of spaces
Disadvantages of Internal wall Insulation
- Internal wall insulation is disruptive to install and can require removing skirting, coving, and fixtures and fittings
- Reduces the size of the room and floor space
- Not always as effective as external wall insulation in terms of thermal efficiency
- When installed incorrectly can be damaging the walls and property structure
External Wall Insulation
External wall insulation is one of the most effective methods when it comes to insulating your home and providing protection against damp and moisture levels. External wall insulation boards are generally applied followed by render or alternative cladding materials to protect the material and create a smooth and sleek product. External insulation is an option when it comes to the walls as it does not disturb the internal aesthetic of the home or family life, particularly for those with children. External wall insulation while recognised as the most expensive is also recognised as the most effective.
Benefits of External Wall Insulation
- External wall insulation will reduce the cold and hot air travelling through the walls
- Protects your property from the elements such heat from the sun and moisture from the rain
- Improves the life expectancy of the walls and will not reduce the floor space
- Does disrupt the internal space in terms of furniture, fixtures, fittings and openings
- Ideal option for buildings that cannot be insulated from the inside of the property
- Suitable for existing buildings, new builds, and refurbishments
- External wall insulation grants are in some circumstances an option
Disadvantages of External Wall Insulation
- The thickness of external insulation board can cause problems when installed around existing windows and doors
- Having to adapt fixtures such as window can be extremely costly
- Can worsen damp if installed without the correct measures in place such as air vents that allow moisture to escape
- External wall insulation projects may require planning permission to ensure it complies with guideline
- External wall insulation costs can be expensive
- May not be suitable for some listed buildings or those in conservation areas
Solid Wall Insulation
Solid wall insulation is a great option for insulating flats, maisonettes and also terraced houses. This is because it is not possible to externally insulate a single property when it is joined to others. Insulating solid walls may be disruptive to your home and work life, however there are benefits. A major plus is that you are able to insulate one room at a time. This means that the whole house is not impacted at once. Conquering one room at a time also allows you to manage your budget more effectively.
Benefits of Solid Wall Insulation
- Fills gaps and cracks within the brickwork which will reduce air flow and draughts passing through the walls of the building
- Great fit for properties and buildings where external changes are not acceptable
- When completed as a system, the wall will be newly decorated and give a sleek finish
- Reduces the risk of condensation and damp which will improve the air quality
- Solid walls can be insulated using mechanical fixings or dot and dab adhesive or both
Disadvantages of Solid Wall Insulation
- Solid wall insulation involves stripping everything back from the wall including drywall materials
- Due to starting the wall again it can be costly when considering products such as plasterboards and coving
- Dependant on the thickness, solid wall insulation can significantly reduce the space in the room
Stud Wall Insulation
Stud walls are made up of a solid timber or steel frame. Not only can the studs be fixed to solid walls, but they can also be used to form a partition wall to separate one space into two or more sections. Using insulated wall studs to separate larger rooms into smaller sections can be an incredibly effective way to improve privacy within your home. With timber frame and steel frame structures you can create spaces personalised to your your needs such as a walk-in wardrobe or bedroom. The extra space within the home will increase the property value. Stud walls can be assembled by builders, contractors and DIY enthusiasts.
Benefits Of Stud Wall Insulation
- Easy and simple to install, cut, and handle
- Acoustic insulation within stud walls will reduce noise travelling between rooms
- Stud walls can be applied directly to solid walls using either timber or metal framing systems
- Multiple insulation types can be applied to stud walls including mineral wool or rigid boards
- Stud walls generally have a thickness of 100mm which is an easy insulation size to get hold of
Disadvantages Of Stud Wall Insulation
- Internal spaces will need to be prepped prior to installing
- When applying to a solid wall, the existing drylining will need to be removed
- Installing an entire stud wall system can require many materials which can be costly
- Insulating a stud wall can reduce sound levels however they are not as effective as acoustic systems in their entirety
- Insulating a stud wall requires a multitude of building materials to ensure it is safe and installed correctly
Cavity Wall Insulation
Cavity walls consist of two layers, known as the inner and outer “leaf” of the wall. Between these layers, there is a gap, also known as a cavity, that allows air to circulate. When the air reaches the cavity, it often leads to heat escaping, which is where cavity wall insulation comes in. Cavity wall insulation is installed into the gap as the wall is being built, between the inner and outer leaf. Cavity wall insulation is an excellent product for new builds and extensions to ensure the newly constructed walls are correctly insulated with reduced disturbance to the interior walls.
Benefits of Cavity Wall Insulation
- The installation can either be for partial fill or full fill applications
- Cavity wall insulation works by capturing the air that has been injected into the cavity space
- Prevents the warm air from leaving the building
- Board sizes designed to fit between wall ties
- Will improve sustainability and reduces carbon footprint by lowering energy consumption
- Can prevent condensation within the walls and damp issues
- Reduces the risk of mould when installed correctly with the required ventilation
Disadvantages of Cavity Wall Insulation
- Damaging if not installed correctly
- When installed with poor ventilation can cause damp and moisture issues
- Initial insulation costs can be expensive
- Can slow down construction turnaround times
FAQs
How do you Insulate a Cold Wall from the Inside?
Cold walls can be insulated from the inside by stripping back all wall finishings such as skirting and plaster until the brick wall is revealed. Timber or metal frames can be fixed to the wall and then insulated with PIR boards or mineral wool. The frame can then be covered with plasterboard or insulated plasterboards and plastered then decorated. An alternative method is directly applying insulation to the brick wall using the dot and dab method.
What is Cavity Wall Insulation?
Cavity wall insulation is a very similar product to PIR boards; however, the cavity boards are such a popular product due to their dimensions that are designed to be easily installed between wall ties. This way the boards will not need to cut until installing around the edges. Cavity wall insulation is also available in two types, partial fill insulation and full fill insulation, one of which requires an air gap, and one does not.
What is the Most Effective Method for Insulating Walls?
The most effective wall insulation will depend on several factors including the specific requirements such as thermal quality, costs, acoustic performance, building regulations, and so forth.
Internal Wall Application Methods Include
- Timber frame Systems
- Steel frame systems
- Solid Wall applications
- Cavity Wall applications
- Party Wall Insulation
- Partition Wall insulation
How to Noise Insulate a Wall?
Noise insulating a wall essentially means to soundproof a space. To noise insulate or soundproof a room, acoustic insulation materials such as acoustic rolls or party wall rolls should applied directly to the solid wall. They can also be applied by installing a wall stud system. Sound plasterboards can then be applied horizontally over the frame or onto the insulation boards directly using fixings.
What does Asbestos Insulation Look Like?
Asbestos can have a grey, brown colour or silvery gold tone and has a pebble like appearance. It tends to be a loose fill insulation type and can resemble a rocky gravel or cotton candy fibre glass.
