Once installed, WARMLINE will keep walls dry and warm, acting as a damp proofing and insulating layer.
Solid wall properties can suffer from damp, condensation and mould, and are less energy-efficient than properties with cavity walls. This is because they’re difficult to insulate and have no air gap to prevent the transfer of moisture.
Warmline Internal Wall Insulation is an innovative solution for damp proofing and insulation strategies in solid wall properties. Thanks to its unintrusive installation and high performance, it’s an effective and convenient choice for treating solid internal walls. Read on to find out more as we explore its properties, applications and how it is installed.
A solid wall has no gap, or cavity between the inner and outer leaves. It’s a traditional form of construction with one layer of brick or stone.
In contrast, a cavity wall has two parallel layers (or skins) with a gap between them. The cavity blocks moisture transference and prevents damp, and the cavity can also be filled with insulation.
Buildings constructed before the 1930s were normally built with a mixture of either solid or a mix of solid and cavity walls. According to a report on Household Energy Efficiency by the Department for Energy Security & Net Zero, there are 8.5 million homes in Great Britain with solid walls. Of these, only around 10% have solid wall insulation.
There are two simple methods you can use to tell if your walls are solid or cavity:
Brick Pattern
If your walls are exposed brick, you can tell by the pattern of the bricks that were laid. If they’re all end-to-end, with the longest side visible, it’s likely to be a cavity wall. If they’re laid in a regular pattern with the long side and short end visible, it’s likely to be a solid wall.
Solid Wall Pattern
Cavity Wall Pattern
Thickness
You can also measure the thickness of the wall to determine if it’s cavity or solid at a door or window. If the wall is more than 26 cm thick, it’s probably a cavity wall. Anything less than this is likely to be a solid wall.
Solid walls can cause a number of issues for homeowners. These are normally around insulation and damp – issues that can seriously affect the quality of life.

These problems can be solved by retrofitting internal wall insulation and damp proofing strategies. Previously, these have been labour-intensive and difficult to install, but Warmline Internal Wall Insulation provides a quick and effective solution.
As we’ve discussed, using Warmline is an effective, quick-to-install and cost-effective way to insulate and damp proof solid walls, but what is it?
Warmline is a thin thermal wall insulation. Supplied in rolls, it can be easily cut to fit any installation location. Due to this, installation causes minimum disruption. It can be applied directly to plastered walls using Warmline barrier grout.
It’s made from a specially woven polyester-based textile material. Features include:
Once installed, WARMLINE will keep walls dry and warm, acting as a damp proofing and insulating layer.
Because they lack a cavity that prevents damp from travelling through them, solid walls need a damp proofing strategy to prevent them from being affected by this issue.
There are a number of different solutions available, but protecting solid walls from penetrating damp with an external waterproofing treatment is a sensible measure.
At Tyne Tees Damp Proofing, we have several solutions available.
Once you’ve protected the exterior of your walls, applying Warmline Internal Wall Insulation isolates finishes from damp, and acts as a solution for both internal damp proofing and insulation.
The combination of an exterior water repellent and an internal wall insulation can work very well, with the water repellent letting the wall breathe and dry out whilst stopping further water ingress. This already increases the wall’s thermal efficiency, and introducing internal wall insulation further improves this.
Careful consideration must be given to eliminating external defects before the water repellent and the Warmline is applied.
Heat escapes more quickly through solid walls than cavity walls. With a cavity wall, insulation is almost always a case of filling the cavity with insulation. With a solid wall, there are a few different methods for insulating them, but they all involve retrofitting.
Insulating a solid wall is definitely worthwhile. It will make your home warmer and more comfortable, saving you money on energy bills and reducing your carbon emissions.
Retrofitted insulation can be applied internally or externally. External wall insulation usually offers greater insulation thickness, but it can be very expensive in comparison and there are many properties that it just won’t suit.
Along with the cost, you will likely require planning permission. It can also be tricky to detail around window reveals, sills and eaves, and any slight cracks or poor fitting can lead to water ingress and trapped moisture.
There are lots of different types of Internal Wall Insulation, and these will normally be cheaper than External Wall Insulation. Cost savings usually come down to how long it takes to install the system. For this reason, Warmline Internal Wall Insulation is one of the most cost-effective and performance-effective options. It’s lightweight, flexible and cuts in easily around light switches and window reveals. The WARMLINE insulation roll is pressed into a trowel-applied adhesive coat and is hung similarly to fitting wallpaper.
The insulation can then be skimmed, and, overall, you have a system that requires fewer installation hours than alternative systems such as cork renders and foam laminates. Renders have longer drying times, and some other forms of TIWI are harder to form around fixtures and more complicated room layouts. This all adds up to higher labour costs. For this reason, WARMLINE represents the most cost-effective solution.
