Loft Insulation Renfrewshire
Retain Up To 25% More Heat With Spray Foam Loft Insulation
What is Loft Insulation?
Loft insulation is a material you place as a barrier between your roof spaces. It is either placed between the rafters (the L shaped beams used to support the roof) or the joists (the horizontal beams fitted along the floor of your attic).
Loft insulation is done in order to slow down and prevent the heat transfer happening between the outside world and your living space. This creates a warmer environment inside the house during winter and a cooler environment during the summer.
The use of loft insulation will retain up to 25% more heat in your home. Spending your money on new central heating and double glazing could be wasted if your loft is not properly insulated, all of our customers report reductions in heating bills and an overall improved temperature in their homes after having Lapolla Icynene spray foam loft insulation installed.
How does it Work?
A quarter of the heat is passed out through the roof if your home is not insulated. Insulating your roof can reduce the use of an air conditioner to great extent and hence reduce your electricity bills.
Loft insulation is very durable and can last for a minimum of 25 years and pay for itself over and over. The insulating materials used are very bad conductors and hence reduces the loss of heat through conduction. The material used also prevents the circulation of air inside the cavity, thereby reducing the loss of heat by convection.
When your home is heated, a large portion of that heat escapes through the roof. An insulated loft reduces the amount of heat passing through the ceiling and traps that heat inside the space below the loft. This means that the warm air from your heater stays in the rooms for a longer period of time. This means you can reduce the time your heater is run at your home, save energy, and in turn, you’re hard-earned money.
The thicker the loft insulation is, the more effective will be for reducing heat transfer. A minimum insulation thickness of 270 mm is always recommended.
Types of Loft Insulation
Sheet insulation consists of firm boards of natural or synthetic material that are the best solution for insulating the down part of the roof. These boards provide very effective insulation for your loft and can be decorated for aesthetics.
Blown Fiberglass Insulation
In this type of insulation different kinds of loose materials are blown between the joists. This is an insulating technique for lofts that are very difficult to be accessed physically and is not a perfect solution, especially in a draughty loft. Also, the cost of insulation is very high and the installation can only be done by a professional.
There are different materials that can be used for loft insulation. The material type and thickness of the insulation determines how much heat can be trapped inside your living space
Blanket insulation is the most common form of loft insulation and is composed of mineral fiber, rolls of glass, rock, or sometimes foil-backed felt. It is one of the cheapest options and is an all-purpose insulation material, especially between joists. It is the easiest material to fit, but cannot be used for the roof.
Loose-fill insulation usually consists of lightweight loose materials like cellulose fiber, granules, recycled newspaper, or even mineral wool. It can be used as a separate insulating material or used to top up the existing one. One drawback of this type of insulation is, it can be very messy and isn’t always very secure.
Spray Foam Loft Insulation (what we Use)
Insulation materials range from bulky materials such as rock, fiberglass, and cellulose, slag wool, and natural fibers to foam boards that are rigid. Bulky materials resist convective and conductive heat flow to a lesser degree. Foam boards trap air or any other gas to prevent airflow to an extent. Less common materials like phenolic and cementitious foams are also available.
Some of the loft insulating materials used are
· Mineral wool
· Natural fibers
· Vermiculite and perlite
· Urea-formaldehyde foam
· Cementitious foam
· Phenolic foam
· Insulation facings
Urea-Formaldehyde Foam Insulation Materials
Urea-formaldehyde (UF) foam was something that was used as an insulating material in the very early days. It was later decided that UF was not fit for residential use and has been discredited for its shrinkage and formaldehyde emissions. It is still used as an insulating material in industrial buildings.
UF foam insulation makes use of compressed air for forming. The Nitrogen-based UF foam is known to take more than a week to fully cure. UF doesn’t expand while curing, unlike the polyurethane insulation. It is very easy for water vapor to pass through it and at prolonged temperatures, it starts to break down.
Cementitious Foam Insulation Material
The cementitious insulation material is used as formed-in-place insulation or sprayed foam, and as the name indicates is a cement-based foam. There are different types of cementitious spray insulation, one being the air krete. The spray foam, air krete has magnesium silicate in it with the
initial consistency of shaving cream. This foam is sprayed into closed cavities and costs about as much as polyurethane.
Phenolic Foam Insulation Material
Phenolic foam or phenol-formaldehyde foam was something that was very popular years ago as a foam board insulation that is rigid. It is currently used as foam in place insulation for lofts.
The phenolic foam uses air as its foaming agent. A major disadvantage of this foam is that it can shrink up to two percent, after curing, which has made it less popular nowadays.
Benefits of Loft Insulation
Loft insulation can be seen as an added protective barrier between your living space and the outer environment. Apart from reducing the transfer of heat to the outer environment, there a lot of benefits to insulating your loft.
· It reduces energy costs to a great extent
· Enhances process performance.
· It prevents moisture condensation.
· Reduces the capacity and size of new mechanical equipment needed to control the temperature
· Safety and protection of personnel.
· Reduces emissions of pollutants.
· Maximizes return on investment (ROI)
· Acoustical performance: reduces noise levels as it tends to absorb noise.
Loft Insulation Cost in Paisley & Renfrewshire
Depending on the type of space you are living in, installing a loft could help your reduce your bills up to £215 per year (on average). The payback time is very less if you previously didn’t have loft insulation at all.
The houses you live in can be divided into three types, terraced, semi-detached, and detached.
According to the data provided by the Energy Saving Trust, the normal cost of loft insulation in a semi-detached house can be about £300. Depending on your living space, this could be more or less. For a detached house, the price can go up to £395 and if you are living on a terrace it can go down to £285.
This might be a bit costly for some of you, but the long term savings are significant. The energy bills in a detached house can be reduced up to £225 a year, and up to £135 in a semi-detached house. This means that it will take only two years for the loft insulation to pay for itself, and after that, you will be saving a lot of money and energy.
If you are a DIY enthusiast, you may be tempted to insulate your loft on your own. This is not recommended, all areas of lofts are often not freely accessible and insulation must be installed between joists. You should always let a professional approved loft insulation installer complete the job.
Loft Insulation Grants and Government Scheme
A new grant has been introduced by the UK government that allows to save two-thirds of the cost of some energy-efficient home improvements. These values can be up to £5,000, or the total cost up to
£10,000 if you are eligible for certain benefits. The deadline for completing home improvement is 31 March 2021, so better act fast.
The long-running Energy Company Obligation (ECO) scheme helps people in the UK on some selected benefits to reduce their energy costs by carrying out some home improvements. The benefits covered are not the same as Green Homes Grant, so it is always recommended to check it out and see if you qualify.
