What is internal wall insulation?
If you own a solid-walled property, internal wall insulation is a highly effective way to reduce heat loss from your home. It involves adding insulation to the interior walls of your home, creating a thermal barrier that keeps warmth in, reducing energy consumption.
Normally a cheaper alternative to external wall insulation, internal wall insulation is ideal for properties where outside insulation is not suitable - such as sandstone buildings.
Although it can be quite disruptive, the installation can be done room by room and there are a variety of products to suit different properties.

Loft insulation is a smart way to cut your carbon footprint and make your home more energy-efficient. Many households across Scotland still lack proper loft insulation, making their homes less comfortable and more expensive to heat.
With Green Home Systems, you can easily upgrade your loft insulation with modern materials like mineral wool or recycled options, using simple methods such as dry-fit panels or laying blanket rolls.
Before you start, it’s important to understand how loft insulation works: it acts as a barrier to trap warmth inside during winter and keep excess heat out during summer. Different materials have different R-values (their ability to resist heat flow), so knowing what material suits your home best is key.
Cavity wall insulation has become increasingly popular as homeowners look for ways to reduce their carbon footprint and energy costs.
The first step is to drill small holes into your home's external walls and inject insulation material into the cavity. The process must be carried out carefully to ensure the cavity is fully filled and properly packed, avoiding cold spots or heat loss.
The type of insulation used depends on your home’s construction and age. Different types of cavity wall insulation have unique lifespans and benefits, so it's important to work with an experienced installer to find the right fit for your property.
Internal wall insulation is fitted between the inner and outer walls of your home. It’s a fantastic way to reduce heating and cooling costs, especially in older properties across Scotland where internal temperatures can vary significantly during colder months.
At Green Home Systems, we use a specially designed foam that fills all gaps and stops moisture penetration, while also providing extra structural strength through advanced additives. The lightweight formula means you get all the insulating power without burdening your home’s walls.
If you're serious about making your home cosier and more efficient, internal wall insulation is an excellent option to consider.
Room-in-roof insulation transforms your attic or loft into a usable, comfortable space while dramatically improving your home’s energy efficiency. Materials like fibreglass, rock wool, or rigid boards are fitted between the rafters to stop heat from escaping.
Proper room-in-roof insulation can prevent heat loss during Scotland’s cold winters and help maintain a steady temperature year-round. Whether you're creating a home office, bedroom, or just want a warmer loft, this type of insulation is key.
Before you start a DIY project, it’s important to get a full understanding of the right approach. Poor installation can lead to serious risks, including fire hazards or structural damage. At Green Home Systems, our professional and experienced installers ensure your room-in-roof insulation is fitted to the highest standards, giving you lasting energy savings, greater comfort, and complete peace of mind.
