Solid Wall Insulation | Insulate Solid Walls | Internal and External Wall Insulation

Solid Wall Insulation

Solid wall insulation can significantly cut your heating costs and make your home, office, or any other building more comfortable. In the UK, if a house was built before the 1910s, then it most likely would have solid walls instead of cavity walls.

Before talking about insulating your solid wall, it is important to know that solid wall have no gaps, which means that it is not possible to fill them with cavity wall insulation. On the other hand, there are two layers in the cavity walls, which has a small cavity or gap between them.

Similarly, you can insulate solid walls either from internal or external means. However, this costs a lot more than the insulation of a standard cavity wall. At the same time, solid wall insulation has a much bigger advantage and that is bigger saving on the heating bills. So, what is solid wall insulation ? Let's take a look at our short guide to understand the process.

Internal Solid Wall Insulation

Internal solid wall insulation consists of the dry lining in forms of built-up systems or pre-insulated plasterboards using fibrous insulation, for instance, with the help of a studwork frame, the holding of mineral wool in place.

In solid wall properties, internal insulation for wall is considered a great option because most of the time, external insulation is not permissible and/or practical. Also, experts recommend dealing with damp or moisture issues before the installation of insulation for the wall. In general, insulating wall internally is more affordable than external insulation as you can do it room by room.

So, how does internal solid wall insulation work? Well, there are several structural techniques and applications to insulate solid walls internally, which are often referred to as dry lining. This involves the insulation of the inside of the solid wall by different techniques or methods using different materials.

The first method is to fix directly the readymade insulation boards to the solid wall, which typically consists of plasterboard with 50mm insulation material. The second method or technique is to attach the framework of wooden battens or timber to the wall – filling the space between the battens with insulation materials. The third technique is about the attachment of the metal framework to the walls and then attaching the insulation boards to the metal frame.

External Solid Wall Insulation

External Solid Wall Insulation covers the external/outside of your house to block thermal leaks. Your home’s external walls act like a barrier, which protects your house or property from the external cold elements and retains heat on the inside. Insulating your wall externally is probably one of the best ways of wall insulation when it comes to minimizing heat leakage and improving your home’s heating energy performance.

With such wall insulation, you can make a significant reduction in the loss of heat – thus also decreasing the amount on your heating bill. Similarly, solid insulation for the external wall can increase thermal efficiency by 85%. There is no loss of internal living space and disruptions to the household are likewise minimized.

In addition, your house or the wall will heat up quicker as well and you and your family will stay warmer for longer. As part of the wall insulation, you will get an attractive, weatherproof, and maintenance-free new outer wall.

Advantages of Insulated Solid Walls

There are many benefits and/or advantages of Solid Wall Insulation. Experts from different companies across the UK say that the insulation of a solid wall can save for you up to 650 pounds a year on the energy bill.

Additionally, the material used in this type of insulation for your wall is breathable (membrane) and eliminates penetrating damp. Wall insulation not only improves your exterior décor but also improve the damaged porous bricks and loose cracked render solid brick wall.

Most often, you will have 10 years of guarantee with little or no maintenance.

Your house will warm up quickly if you insulate your solid wall . That said, you don’t need to keep the heating on in order to reach a suitable or comfortable temperature.

So, it’s time to say goodbye to the condensation – because, without it, there will be less growth of mold – thus leading to a good healthy living environment and extended life for your wall

When you install the external solid wall insulation by a professional installer, you will transform your home with a wide variety of traditional or contemporary finishes with a sophisticated choice of colors, textures, and finishing effects.

The loss of heat measured at high levels can result in a high carbon footprint. However, you can reduce these levels by installing the right wall insulation for your solid wall. This way, user will save money as well as play a role in the protection of the environment by reducing the levels of carbon emissions.

Let us now talk about the best brand that provides insulation for the solid wall which you can purchase at the most affordable prices.

Cavity Wall Insulation

Cavity walls are made up of two thin walls (usually made of brick, referred to as 'skins' or 'leaves') and a gap (or cavity) between them. They are joined together by metal wall ties.

It is likely that housing properties constructed between 1924 and 1982 have a cavity between layers of brick, or between bricks and blocks, that was not filled with insulation when the property was built. Several properties built after 1982 do not have cavity insulation, and in most areas, we can help with a grant if it was built before 2005. 

Cavity Insulation is typically made from shredded mineral wool (glass fiber) or polystyrene beads that can reduce the amount of heat escaping from the walls by up to 35%.

With cavity wall insulation, you can save up to £145 per year on energy bills and reduce carbon emissions by up to 610kg.

Rigid Insulation

Rigid insulation is made from rugged, dense sheets of certain types of foam.

The vast majority of houses in the country still use batts or mats of soft insulation. Among the most popular insulation alternatives for homeowners are fibreglass, cellulose, and even natural sheep wool insulation.

Foam products such as polyurethane, polystyrene, and polyiso are commonly used for rigid board insulation.

Closed-cell insulation products are often stronger, more durable and resistant to natural elements. They also have a higher R value than open cell ones which makes them better for your home's temperature control needs.

Cost of Installing Solid Wall Insulation

If you opt to install external solid wall insulation, then typically, a company in the UK will cost you between 8,000 pounds to 22,000 pounds. Likewise, internal solid wall insulation costs from about 3500 pounds to 14,500 pounds.

Conclusion

If your home’s walls are not insulated, then there is a higher risk of heat loss through the walls – causing damp or moisture that could lead to plaster and paint degradation(causing green or grey patches), unstuck wallpapers, as well as the growth of mold and mites. Therefore, effective wall insulation for solid walls can significantly help to limit condensation – helping to handle the issues related to damp.

Another issue that can cause harm to your health is noise pollution. You can reduce the disturbing noise traffic by installing solid wall insulation – because you will live comfortably when you have a quieter home. Lastly, a thermally efficient and well-insulated home also provides fire-retardant properties, which certainly increase the value of your property.
