What is Internal Wall Insulation
Internal Wall Insulation involves fixing insulated plasterboard to internal walls. This is to increase the thermal efficiency of the property on a room-by-room basis. By doing this, it traps heat and therefore keeps it warm in Winter and cool in Summer. After installing internal wall insulation, you can expect significant annual savings. This is especially true for properties where other insulation services aren’t suitable or not desired.
What is a Solid Wall?
Was your home built before 1920? If so, it is likely that this has solid walls, meaning that there is no cavity available to insulate. Therefore the best method of improving the energy efficiency is by either insulating the exterior of the house with cladding, or by insulating internally.
If you can see the external brickwork of the property, you can typically identify whether your home has solid walls or a cavity. If your home has solid walls, the bricks will be alternating in size, as some of them will be laid across the wall, resulting in an uneven pattern.
If all the bricks have an even pattern, it is likely that this is a cavity wall.
Additionally, you can look to measure the thickness of the wall itself. If it is more than 260mm, it is likely to be a cavity wall. Smaller than this, it is likely to be a solid wall
How is it Insulated?
Internal Wall Insulation involves fitting rigid insulation boards to the walls inside of your home, typically using a stud wall.
Internal Insulation is typically cheaper than external wall insulation/cladding but reduces the size of the room slightly due to insulating from within. While this can be disruptive, it is easy to do room by room, preventing the need to disrupt the entire house.
In addition, internal wall insulation comes with redecorating and new skirting boards throughout the room.
As PAS2030 accredited installers, we also carry out a full ventilation and condensation assessment on our room in roof properties, to ensure that the house is breathable and does not run the risk of condensation or mould build up. If needed, we can install window ventilation and mechanical ventilation (extractor fans) in the areas most prone to damp and condensation, such as the bathroom and kitchen.
How Much Can I Save with Internal Wall Insulation?
The amount you can save depends on how much energy you currently use, and the size of the space that is being insulated. On average, our internal wall insulation projects can save up to £650 per year for a standard detached house.
Is There Funding Available?
Inefficient homes (with an EPC of F or G) could access funding via ECO4 to receive full or partially funded insulation. Contact us today to find out more.
