Internal Wall Insulation

Internal wall insulation is a method of insulating the interior surface of external walls. It is a viable alternative to external wall insulation and, in our opinion, a superior approach for properties with appealing character. Heat loss from solid-walled properties is mainly due to heat escaping through the walls, which accounts for nearly half of the total heat loss. By insulating these walls, the rate of heat loss can be reduced, keeping the warmth inside your home for longer. Internal wall insulation involves adding an extra layer of insulation to the interior walls, which can significantly enhance the overall appearance of your property.

Our internal wall insulation is implemented by mechanically fixing and gluing insulated PIR boards onto the existing walls within your property. While insulating solid walls from the inside is typically more expensive than insulating a standard cavity wall, the resulting energy savings on your heating bills are generally more substantial.

If you want to keep your home warmer and more energy-efficient, you can insulate the walls using a method called dry lining. This involves adding insulation to the inside of your walls using one of three methods:

  1. You can attach pre-made insulation boards directly onto the wall. These boards are made of plasterboard and come with up to 50mm of insulation material or mineral wool already attached.
  2. Alternatively, you can create a framework of wooden battens on the wall and fill the space between them with insulation material.
  3. Another option is to attach a metal frame to the wall and then fix insulation boards to the frame.

By insulating your walls, you can help to reduce your energy bills and make your home more comfortable to live in.

  • Insulating internally is easy to install and doesn’t require scaffolding.
  • It won’t change the appearance of your home from the outside, making it a good choice for visually attractive or period properties.
  • Internal insulation is also suitable for flats and maisonettes where external insulation may not be an option.
  • If you live in a Conservation Area with strict rules about changing the outside appearance of your home, internal insulation can be an acceptable option.
  • Lower installation cost compared to external wall insulation
  • Easier maintenance than external wall insulation
  • No scaffolding required for installation
  • No disruption to building appearance – ideal for installation in conservation areas
  • Installation not delayed by bad weather conditions
  • Can be installed on a room-by-room, single facade, or whole-house basis, or as part of a full refurbishment plan.
