Keeping your home warm during cold months and cool in the summer is important in Ireland, Premier Insulations where weather can be quite unpredictable. One of the best ways to do this is by improving your home’s insulation. Good insulation helps reduce heat loss, lowers energy bills, and makes your living space more comfortable all year round.
In this article, we’ll explore the types of insulation available in Ireland, how much they cost, the benefits of insulation, and how to choose the right service provider.
What Do Insulation Services Include?
Insulation services help improve the energy efficiency of homes by installing materials that prevent heat from escaping or entering. These services may include:
Home energy surveys to check your insulation needs
Installing insulation in attics, walls, floors, and roofs
Removing and replacing old or damaged insulation
Energy rating assessments (BER certificates)
Guidance on SEAI grants to help reduce your costs
Professional insulation companies in Ireland also offer advice on choosing the right type of insulation for your property based on its age, structure, and energy performance.
Common Types of Insulation in Ireland
There are several types of insulation used across homes in Ireland. Each one targets a specific part of the house:
1. Attic Insulation
Heat naturally rises and escapes through the roof. Attic insulation helps trap that heat, making your home warmer in winter. It is one of the most affordable and effective options.
2. Wall Insulation
Walls are a major source of heat loss. There are three ways to insulate them:
Cavity Wall Insulation: Insulating the space between inner and outer walls using bonded beads or foam.
Internal Wall Insulation: Fixing insulation boards to the inside of the wall – ideal for older homes.
External Wall Insulation: Adding insulation to the outer walls and finishing with plaster or render.
3. Floor Insulation
Cold floors can make a room uncomfortable. Adding insulation beneath floorboards or concrete slabs helps reduce heat loss and improve warmth.
4. Roof Insulation
For converted lofts or rooms with sloped ceilings, roof insulation between rafters is essential to prevent heat from escaping.
5. Pipe and Tank Insulation
Insulating water pipes and hot water tanks helps maintain heat and prevents freezing in colder months.
Why Is Insulation Important?
There are many benefits to properly insulating your home:
Energy Savings: You’ll use less energy to heat your home, which leads to lower utility bills.
Comfort: A well-insulated home stays warm in winter and cool in summer.
Noise Reduction: Insulation also acts as a sound barrier, reducing noise from outside or between rooms.
Eco-Friendly: Using less energy helps reduce your carbon footprint and protects the environment.
Better Home Value: Homes with high BER (Building Energy Rating) scores are more attractive to buyers.
