Roof Insulation The Borders
Roof insulation is a protective blanket over your house or building. It is fixed between the roof deck and the roof’s surface and is used to reduce the heat transfer from the interior to the exterior. During warm climates, a combination of roof technology can be used along with the insulation to reduce the energy bills that arise when you try to moderate the building’s temperature.
Roof Insulation is of two types – It can either be cold insulation or warm insulation.
In warm insulation, the insulating material is placed directly under the roof. It is done to reduce the loss of heat, to prevent your home from being excessively cold in the winter or hot in the summer.
Cold insulation is comparatively inexpensive and has its downsides. It is usually placed on the ceiling of the top floor.
How does it work?
Roof insulation is a barrier of different materials in your roof space. It slows down the heat transfer between the place you live in and the outside environment, creating a cooler home in summer and a warmer one in winter. Insulating between the joists helps keep the warmth in your rooms below while the loft remains cold, whereas insulating the rafters keeps both the rooms and loft warm.
The insulating materials used are bad conductors of heat and hence reduces the loss of heat by conduction. The material also does not allow the air to circulate in the cavity and therefore reduce the heat loss by convection.
Types of Roof Insulation
There are a variety of rigid insulation materials available that include, perlite, wood fiber, polyisocyanurate, cellular glass, expanded or extruded polystyrene, gypsum board, etc.
Wood fiber is organic in nature and is composed of wood, vegetable fibers, or cane mixed with binder and fillers. The insulation will either be asphalt coated or asphalt-impregnated to ensure more moisture resistance.
Perlite insulation board consists of expanded, inorganic siliceous volcanic glass and perlite mixed with organic binder and fibers. The upper surface of the insulation board has a proprietary coating or an asphalt coating developed to limit adhesive.
Polyisocyanurate is a foam plastic insulating core applied between organic or inorganic glass-fiber mat facers, glass-fiber-reinforced aluminum foil facers, or felt facers. A blowing agent free of chlorine helps to expand the foam material and create a closed structure that provides the insulation with high thermal resistance. Air diffusion to the cell structure of the insulation can reduce the thermal resistance slightly, but the insulation efficiency will remain untouched.
Polystyrene insulation can be made either by expanding or extruding. In expanded polystyrene, the polystyrene polymer is impregnated with a suitable foaming agent. Exposure to heat expands the material and it is then molded to a closed-cell, uniform insulating material. The density of expanded.
Polystyrene can range between 0.70 to 3 pounds per cubic foot. A minimum density of 1.25 PCF is required by most roof covering manufacturers.
In extruded polystyrene, blended polystyrene polymer is heated and then run through an extrusion process. The material expands when exposed to atmospheric conditions and creates a closed-cell structure. The density of extruded polystyrene can range between 1.3 to 2.2 PCF.
Cellular Glass Insulation
Cellular glass insulation consists of a combination of crushed glass and a suitable foaming agent. The components are first mixed together, then placed in a mold. It is then heated to melt the glass and decompose the foaming agent. This process results in the expansion of the mixture and creates a close celled, uniformly connected insulating material.
Gypsum Board Insulation
Gypsum board is a non-combustible, water-resistant, non-structural, treated gypsum panel. These boards have a proprietary, non-asphaltic, single side coating to ensure enhanced roof-membrane adhesion. Gypsum board usually serves as a cover board on top of foam-plastic insulations, as a vapor-retarder substrate, or as a thermal membrane on a steel deck
Spray Foam Roof Insulation
The most commonly used rood insulation material is Polyurethane spray foam. It is applied directly onto the tiles, slates or roofing felt on the down portion of the roof and bonds them firmly to the rafter timbers (load-bearing) and each other. After installation, this insulation can help to reduce your energy bills by 20 percent and hence reduce your co2 footprint.
Greater acoustic insulation is provided by spray foam systems, than fiberglass or other types of insulation. This insulation is found to have the acoustic benefit equivalent to double glazing at a thickness of 75mm. spray foam will also help to extend the durability of your existing roof and reduce future maintenance to some extent.
· A spray foam ensures you have a cooler property in summer and a warmer property in the winter, providing great comfort and energy efficiency
· There are many allergy issues related to different insulating materials. Some of these can be very dangerous and energy-consuming. A spray foam system helps to reduce the dust due to the blowing of winds to the loft space
· A stronger and more stable rood is provided by the spray foam system due to foam’s great strength to less weight ratio
· Spray foam systems can help to prevent condensation in the roof space of your home reducing the chances of corrosion, dampness, rotting timbers, and mold.
· It can help to create more usable loft space and maintain aging roofs
· Spray foam is chemically inert and does not attract insects, birds, or rodents by which access to vermin can also be prevented.
Benefits of Roof Insulation
Roof insulation might be one of the best decisions you make for your home and yourself. There are a lot of benefits that you can gain through the insulation of your roof, some of them being
Energy & cost efficiency – About 30 percent of the heat loss of a building is through its roofs. The installation of efficient insulation helps to provide both money and energy.
It provides an extra layer of protection – It can prevent any potential damages that can arise due to ice dams and moisture, and increase the life of your roofing.
It reduces carbon footprint – according to studies conducted by various institutions, efficient roof insulation helps to reduce CO2 emissions and help fight air pollution
It prevents mould growths – Insulation is the best measure to prevent the forming of moulds. It helps to manage the moisture content and temperature of your home, two factors that affect the mould growth
Opting for roof insulation may feel expensive at the beginning, but in some time you will be saving more than you imagined. SO, go for it.
Roof Insulation Cost
Insulating the roof is one of the smartest investments you can make. As heat rises at your place, 25 percent of the heat is lost through an uninsulated roof. Taking the high energy costs and grants into consideration, the investment can be earned back pretty fast. The average cost of commonly used roof insulation is nearly £25 per square meter (PSM), while spray foam costs about £30 per square meter. So the average cost of insulating the roof of a property will be about £400 to £500.
Roof Insulation Grants The Borders
The Government’s ECO Scheme provides grants to Under Floor Insulation, Room in Roof Insulation, Flat Roof Insulation, Loft Insulation, etc.
The ECO scheme (Energy Companies’ Obligation) was set up for the biggest energy suppliers to contribute to support British households and make them more energy efficient. The ECO scheme (Energy Company Obligation) can give the households subsidized or free home improvements for energy saving.
Roof Insulation Installers Scottish Borders
There are a number of roof insulating contractors and companies spread across the UK. Most of them provide the best services to their customers. You can ask your friends with roof insulation about the contractors they hired or depend on the web to find about them. All the contractors and companies, with their contact details, reviews, and ratings are given on the web for you to choose from.
Room in Roof Insulation The Borders
Room in roof insulation is the process of insulation boards or spray foam being installed between your roofs rafters to seal the roof and walls tight and retain more heat inside the home.
The term room in roof insulation is used for homes with a loft that is used as a living space or room. If you do not use your loft as a living space you would be better off installing standard loft insulation.
Room in roof insulation is available as more traditional foam insulation or spray foam.
We always install Lapolla spray foam for maximum performance reducing heat loss by up to 25%.
