If your loft has been converted into a habitable space then standard loft insulation is not suitable. Some lofts may have been insulated when they were converted, but if not the unheated space still needs to be insulated to prevent heat from escaping.
Room-in-roof insulation involves fitting insulating material between and over the rafters the sloping timbers that make up the roof itself. This can be done with rigid insulation boards, cut to size, or alternatively you can have foam insulation sprayed between the rafters. Plasterboard is then applied on top of the insulating material to create the walls and ceiling of the room. If you want to install room-in roof insulation after your loft has been converted you will need to factor in redecoration costs as the plasterboard will need to be removed.
Room-in roof insulation is also generally more expensive than standard loft insulation as it usually requires the work of a trained insulation specialist, rather than being a DIY job. If you were to do the work yourself be aware that as well as insulating the roof, you will have to insulate all areas, including any gable walls, stud walls, party walls and chimneys in the loft space.
If you leave these uninsulated, then the heat will bypass your new insulation making it largely ineffective, and potentially causing cold spots and damp issues.
Flat roof insulation is most likely to be relevant on extensions, such as a kitchen or bathroom. These roofs can lose a lot of heat and are expensive to insulate, so it is usually best doing it at the same time as regular maintenance or repairs.
With warm deck insulation a layer of rigid insulation board is laid on top of the existing roof deck, with a vapour barrier in-between to prevent condensation build up. A new roof deck is then fitted on top of the insulation boards. With cold deck insulation the internal ceiling is removed and either mineral fibre or rigid insulation boards are added between the roof deck and the ceiling, with at least a 50mm gap between the insulation and the deck.
A vapour barrier is created between the internal ceiling and the insulation. This work should always be done by a professional. Even so, cold deck insulation is usually not the most effective way of insulating a flat roof due to potential condensation build up if not done properly.
With the right approach, you will need a specialist to insulate your roof. If your loft is easy to access and has no damp or condensation problems, it should be easy to insulate. Spray Foam Insulation is a superior product compared to all other types of loft insulation.
Spray foam insulation once applied, expands to roughly times its original volume and as a result fills every crack and crevice to eliminate air leakage or infiltration. To be honest spray foam loft insulation costs considerably more than traditional insulation, but it is the most superior form of insulation on the market today.
As well as insulating the roof, we do recommend the gables to be included to maximise efficiency. Visit page here. PROS : 1. Eco Friendly : Spray foam insulation is an ecofriendly product and reduces your carbon footprint. Breathable insulation : Icynene open cell insulation allows the timbers to breathe,which also prevents moulding and condensation. Reduces Noise Pollution : Icynene Spray foam insulation minimises airborne sounds. Fills all gaps : Spray foam insulation is ideal for roofs, walls, lofts, underfloor and attics.
CONS: 1. Not a DIY product : Icynene Spray foam insulation can only be installed by a licensed accredited installer, you cannot do it from a local store. Not the cheapest Solution :Not the cheapest Solution: Spray foam insulation costs more than traditional insulation methods on the market. The transfer of heat is slowed down with fiberglass insulation because the glass fibers trap air bubbles. These bubbles create an insulating effect by slowing heat exchange between areas and surfaces.
Fiberglass insulation usually comes in batts or rolls. In order to be completely effective, fiberglass insulation must be cut carefully around obstacles such as power sockets. This can be incredibly time consuming.
Fiberglass insulation is significantly cheaper than spray foam insulation , but it is also less effective, especially in winter. Fiberglass is the most common type of loft insulation, however, is outdated and has to be topped up every 5 years because it deteriorates through condensation issues. Warning: The tiny fibers of glass from fiberglass insulation can irritate your skin and eyes.
Breathing in fibers can also increase the difficulty of breathing according to HowStuffWorks. Professional installation is required for spray foam insulation, where as fiberglass insulation can often be installed by homeowners themselves. Fibreglass insulation does not burn 2. Fibreglass insulation is available in High and Medium density options 3. Fibreglass insulation is inexpensive 4.
Fibreglass or Glasswool insulation forms a protective vapour barrier. These silvers if inhaled will lead to skin and respiratory disease. Mineral wool can be obtained in rolls and comes in varying thicknesses and widths. Rock mineral wool is a very effective fire safety measure as it is resilient to heat and fire. Sheet loft insulation comes in sheets and is usually used to insulate the sloping side of the roof inside a loft.
This type of insulation can be more expensive and is energy intensive to manufacture but has a high insulation value. One of the more common forms of insulation is loose-fill and blown-in cavity wall insulation. Loose-fill takes the form of small particles that form a material that can conform to any space without disturbing structures. The most commonly used material for this type of insulation is cellulose, fibreglass and mineral rock wool which are all produced from recycled material.
Sprayed foam is also a common insulation and works in a similar way with liquid foam being poured or injected into place into wall cavities making it very versatile. Sprayed in foam is installed using a foaming agent and will expand and become solid as the mixture cures. Slow curing foams are available which will flow around any obstructions inside the wall cavity before hardening.
Structural insulated panels are prefabricated panels that can be used in wall, roofs and floors. They offer excellent insulation in comparison with traditional methods. They typically consist of 4 to 8 inch thick panels that are made to fit in a factory then shipped to the site and can be made to various sizes. If you're planning to use your loft as a hobby room then you might want to consider up to 40m2.
Please try to take 2 photos of the hatch area from below at different angles and if possible another from above the hatch.
