Is your building struggling to retain heat? You’re not alone. When your property can’t keep the cold out and the heat in, you’re looking at higher costs, colder winters, and a huge environmental impact. Luckily, internal wall insulation, applied to the interior of external walls, might be exactly what you need to reduce heat loss. Here’s what to consider:
Do I need to insulate my internal walls?
Internal insulation is ideal for certain buildings, especially those with solid walls made of stone or brick. Cavity walls require specialist cavity wall insulation.
- Solid walls: Look for an alternating long-short brick pattern.
- Cavity walls: Bricks showing only the long edge.
Choosing the right type of internal solid wall insulation
The right choice is crucial for maximising comfort and efficiency in your building. While consulting a specialist ensures tailored advice, here are some popular options to consider:
- Rigid foam insulation: Expanded polystyrene (EPS) and extruded polystyrene (XPS) offer a range of thicknesses, excellent thermal resistance, and effective soundproofing.
- Mineral wools: Mineral wool insulation from trusted brands like Rockwool and Knauf offer heat resistance, soundproofing, and resilience against moisture and fire – ideal for robust internal protection.
- Rigid insulation boards: Polyisocyanurate (PIR) and polyurethane (PUR) boards from Kingspan or Celotex deliver superior thermal insulation with thin panels – perfect for maximising interior space without compromising on insulation.
- Natural materials: Eco-friendly choices such as sheep’s wool, woodfibre, and cork enhance breathability, control moisture, and can be easily installed between studs or directly on surfaces.
Remember, most products can come in rolls or slabs, which both offer their own unique benefits. Internal insulation rolls are more flexible around curved walls, whereas slabs are more rigid, but can be installed easily.
Benefits of installing insulation for internal walls
Internal wall insulation is a win-win, cutting heat loss to reduce operational costs and environmental impact. It’s ideal for properties where cavity or external wall insulation isn’t an option and significantly reduces internal condensation.
However, it has a few disadvantages that must be considered. Installation may disrupt room use and require some adjustments to pipework and wiring, which might be tricky to work around if your business needs to operate in these rooms every day. Similarly, it reduces floor space too, which might be an issue if your property is on the small side as it is.
