Cavity Wall Insulation:
The Installation of Supernova Silver Cavity Wall Insulation is both simple and efficient. A series of 22mm holes are drilled in such a way to guarantee complete fill of the cavity every time. The injection nozzle is placed in each hole, the system set into motion and the polystyrene beads injected into the cavity under pressure, having been coated in a thin uniform layer of adhesive. When each hole is filled the backpressure causes the system to shut down, thus cancelling out the possibility of overfills. This process is carried out on every injection hole from the lowest level to the highest, thus guaranteeing a complete fill of the cavity every time.
Due to the unique flow characteristics of Supernova Silver Cavity Wall Insulation within a cavity wall situation, the number of holes required is kept to a minimum. This can be approximately half the number of holes drilled by installers using various other types of materials.
This specially adapted drilling pattern leaves the making good process on all existing properties much easier than some other systems, due to the reduced number of injection holes and the fact that each is only 22mm in diameter.
Advantages of Supernova Silver Cavity Wall Insulation
• Further Reduces heat loss by 15-20% through the walls, reducing fuel bills
• Better thermal performance than other systems due to low thermal conductivity (K Value = 0.033 W/m2K)
• Further reduces carbon dioxide emissions
• Improved Livi
Solid Wall Insulation:
Solid walls lose even more heat than cavity walls; the only way to reduce this heat loss is to insulate them on the inside or the outside.
This will help stop heat being lost from your home and help to prevent condensation on the walls and ceilings. It's not cheap, but you will soon see the benefits to your heating bill and it's another way of playing your part in reducing carbon dioxide (CO 2) emissions. There are two types of solid wall insulation: external and internal.
External wall insulation
How external wall insulation works
This involves adding a decorative weather-proof insulating treatment to the outside of your wall. The thickness of the insulation needs to be between 50 and 100mm and is usually installed where there are severe heating problems or the exterior of the building requires some form of other repair work providing the opportunity of adding insulation.
If you are going to be renovating or repairing the exterior of your walls of your house then this is a very good time to consider installing solid wall insulation. In this case, the marginal cost of external solid wall insulation (i.e. the material costs and labour when other wall repairs are being undertaken) will be lower than the full cost of installation.
Internal wall insulation
Solid walls can also be insulated by applying internal wall insulation. Types include ready made insulation/plaster board laminates or wooden battens in-filled with insulation.
How internal wall insulation works
Insulation/plaster board laminates usually consist of plasterboard backed with insulating material typically to a total thickness of up to 90mm. The construction of the laminates reduces the amount of heat which would otherwise pass through into the wall and outside.
How it is installed
The boards are fitted directly to the inside of the wall. The thicker the board the better the insulation. You can also attach wooden battens in-filled with insulation to a wall. This involves attaching battens to the wall, filling the spaces between the battens with insulation and then covering them with a plasterboard finish.
