Extending the space in your home has, over the last 7 years, been an ever-growing trend amongst home owners. The return on investment for expanding the number of rooms in your property generally means the value of your property increases beyond all costs of doing the work.
Room in roof insulation makes loft conversions possible. Generally, loft insulation is installed in the floor of the loft, rather than the ceiling. This keeps the warmth of the house locked in from your highest storey (you may have more than a ground and first floor property), downwards.
This demand for greater flexibility in your current property is one that works financially and from an increase in living space. As it’s existing (albeit, unused) space, it means you don’t need to build an extension – saving all the costs associated with preparing and building on your property and the loss of land/garden space. It makes use of unused space and means you’re not having to sacrifice other space to get more!
Can you have a Room in Roof Insulation Installation?
You need to have a good existing roof structure. That means, no damp and mould on rafters, joists or plaster boards. No holes in your roof or signs of water penetration (on timbers and wall areas). You can’t install when timbers are flaking and weak.
There are 4 types of Room in Roof insulation: Polyurethane, Phenolic Foam, PIR and Mineral wool.
So, what happens?
There’s a survey pre-installation. This ensures the correct thickness gets installed.
If you have no loft access, the installation team find the best location which works for you. When this is agreed, the access is safely made with no damage to your home. From this, a new hatch is made, which is fire rated.
The insulation is then installed to all stud walls with no gaps. This can be cut to size and friction fitted if required.
Where there are sloping ceilings, the insulation is installed with as little gap as possible. Where plasterboard already exists, the insulation board is cut slightly smaller than the gap so allow the board to slide into the voide more easily. Throughout, a 50mm gap is required to exist between the insulation board and the roof line to keep a flow of ventilation. Netting is used at the bottom of each section to keep the insulation board from slipping back down. This ensures the installation keeps the ventilation flowing. Over boarding is an option used when there are issues with the sloping ceiling that are causing problems with installing the insulation. Vaulted ceilings need to have a small ceiling section constructed (see diagram below) with openings for each rafter to maintain the ventilation flow around the Room in Roof installation.
For low-level ceilings in e.g. residual lofts, areas behind the stud walls are insulated with quilt insulation and are cross-laid to prevent any cold bridging (where funding is available). Ventilation in the eaves is kept clear.
For high-level ceilings, room in roof insulation ensures there are no gaps and the ceiling is fully insulated. Quilt insulation is installed in this area and cross-laid to prevent cold-bridging, again ensuring adequate ventilation exists.
Rules and regulations are in place for safe electric use following best practice protocols. PAS 2030 Regulations are followed for aspects such as where amenities within the loft area are more than 1m away from the door or the hatch and require a walkway to be installed. Pipework and water tanks are also insulated to these regulatory standards. The loft hatch and door, unless pre-insulated, must have the same degree of insulation as the surrounding area. Where burning appliances are installed, combustion ventilation is required within the room in roof installation. These follow clear C.I.G.A. and building regulatory requirements. On completion, the installer is required to staple a loft certificate and 2 warning signs to the rafters in each part of the loft area which states the depth installed and the materials used. Information for fire-related hatches is also stapled.
All works are done to a highly satisfactory standard at Green Deal Solutions.
