Home Insulation

Attic Insulation

Attic or loft insulation is the most cost effective insulation you can fit to your home. The current SEAI standard is a depth of 300mm / 12″ unless your home has been insulated recently it is unlikely to have this depth.

Remember once you have the insulation fitted the roof space will be much colder in winter so get all your pipes and water tank insulated at the same time.

While you are in the roof space check what ventilation it has. If you do not have soffit vents it might be worth fitting ventilation tiles to maintain some air circulation in this otherwise unvisited place.

 

Roof Insulation

This kind of insulation is normally fitted when the building is being constructed. Unfortunately many flat roof extensions often had little insulation at all.

Retro-fitting insulation into flat roofs is more involved but can still be done.

Wall Insulation

Which wall insulation is best for your property depends on how the walls were constructed when it was being built.

There are three types of wall insulation:

• External – outside,
• Internal – inside the rooms,
• Cavity – inside the walls themselves.

 

Cavity Wall Insulation

Cavity insulation is now fitted when the building is being constructed, but if your home was built even just a few years ago it might not have any. The two main types are Blown Fibre and Bonded Bead.

The basic idea is the same for both types, holes are drilled in the wall and the insulation material is inserted.

Retro fitting cavity insulation is the cheapest and least disruptive of the wall insulations, generally done and cleaned up in one day. The illustration on the right shows how SupaBead Bonded Bead insulation is applied.

 

Internal Insulation – Dry-lining

This method of insulation involves fixing a layer of insulation material to the inner surfaces of your external walls.

This method can be disruptive as any obstacles that may be on the wall will have to be removed and re-instated when the new insulated wall is finished ( i.e. skirtings, window boards, any electrical sockets, radiators etc.).

All new walls need to be plastered before they are ready for decorating.

 

External wall insulation

External insulation involves fixing insulating materials to the outer surfaces of the walls of your home.

The insulation, such as mineral wool or expanded polystyrene slabs, is then covered with a special render to provide weather resistance.

A steel or fibreglass mesh is embedded in this render to provide strength and impact resistance.

Underfloor insulation

Under floor insulation for solid floors is best done when constructing the floor.

If you have suspended timber floors then insulation can be added between the supporting joists.

How practical this is depends on the type of floor you have and the void under the joists.

Although only 10% of heat escapes through the windows, this is the thing many home owners upgrade first.

Sealing up badly fitting doors and windows, gaps between floors and skirting boards etc. can save just as much heat at almost zero cost. As 25% of heat escapes through the roof, attic insulation will give you the biggest benefit for the least financial outlay.
