Solid Walls - How to achieve 0.18 U-value
How to achieve a 0.18 U-value for solid walls
Are you going through building regulations for an upcoming project? You've likely been asked to achieve a 0.18 U-value for your walls if you are seeking acceptance from building control. Hitting this figure can be straightforward, however, can be much more difficult with cost and space restraints.
Understanding U-values
U-values measure the level of heat transfer through a structure. It is a sum of all the layer's thermal R-values (thermal resistance) that makes up that part of the building. For example, a roof has a U-value, a window has a U-value, and so on. Achieving a U-value is often crucial, as there is a minimum expectation to achieve building regulations.The U-value target for 2024
The government has updated its Approved Document Part L about U-values, heat gain, and heat loss. The new target U-value came into play in June 2022. For more information on Part L follow the link on the UK government website - See Data Source.
New for 2023 – U-value requirements for existing dwellings |

| Application | Current U-value |
| Roof (Flat Roofs & Pitched Roofs) | 0.15 |
| Wall | 0.18 |
| Floor | 0.18 |
Types of solid walls
There are many different terms and expressions used in the building trade, often relating to the same thing. Solid walls, often being branded as Dry Lining, include the following types of walls;- Cavity wall - Brick and Block
- Concrete walls
- Block and Render walls
- Brick walls
Products to achieve a 0.18 U-value
Here at Ecohome Insulation, the product we'd highly recommend for insulating solid walls is YBS SuperQuilt. SuperQuilt is a thin flexible and extremely high performing for its thickness (40mm relaxed, 7mm compressed). Here are some of the key benefits of YBS SuperQuilt- Built-in vapour control layer
- Fully certified - BBA & BDA
- Itch-free and floating fibre free
- UK manufactured
- Made from 83% recycled materials
- Class E surface spread of flame
How to install YBS SuperQuilt for 0.18 U-value
To achieve this popular U-value we recommend using a double layer of YBS SuperQuilt. This detail will provide incredible cost savings vs insulated plasterboard, and it's a proven space saver.- Build-up from External to Internal
- Solid Wall – E.g. Brick, Block, Stone
- 25mm Vertical Batten
- 1st Layer SuperQuilt stapled taut to battens (7mm compressed)
- 38mm Horizontal Batten
- 2nd Layer SuperQuilt staples taut to battens (7mm compressed)
- 25mm Vertical Batten
- Standard 12.5mm Plasterboard Finish
- U-value Achieved – 0.18 U-value
- Total space lost, from internal wall to finished plasterboard = 114.5mm
