Roof Insulation
• Retain heat in loft spaces by stapling — foil face inwards — to the underside of roof rafters (foil face outwards if plaster board is be fixed to rafters).
• Helps keep unfelled roof spaces free of dust and dirt.
• Leave 100mm ventilation gap at top and bottom of foil to aid ventilation.
• Overlap foil by min 75mm.

Wall Insulation
• Insulate and help exclude penetrating damp or condensation in one operation — staple foil face to wall on then timber battens.
• Fix standard plasterboard to complete dry lining of wall.

Floor Insulation
• Insulate and draught proof under suspended timber floors by draping (foil face upwards) over timber joists to allow min 50mm air gap under floorboards.
• Reduce the feeling of cold underfoot by using as extra thermal insulation under carpet underlay — foil face downwards.

Radiator Reflector Foil
• Insulates and reflects heat from radiators.
• Suitable new or existing radiators.
• Easy to cut and fit with self adhesive pads.

How to use

• Fix double sided adhesive pads along the top and bottom edge on bubble side as shown.
• Cut slits, if required,in line with radiator brackets. Press radiator Foil firmly into position.

Please note: This product may interfere with TV receivers using internal loft aerials.

Acoustic Panels for party brick wall (Up to 13db)
• Acoustic panels can be an effective and cheap solution to damping airborne noise passed through a brick party wall. Due to advances in acoustic damping technology, they create a balance between increasing the mass of the wall transmitting the airborne noise, and a spring type action brought on by the air caught in a special acoustic mineral wool layer. Dependent on manufacturer, acoustic panels may increase your acoustic damping by up to 13db.
• Most acoustic panels, are derived by a process that combines a mineral wool type layer, directly bonded to a second layer of acoustic plasterboard. This solution is generally targeted at party walls consisting of at least 100mm of brick (44db – 48db). Acoustic panels are not suitable for breeze block type party walls, or stud / wooden frame type walls due to their specific acoustic properties.

Upgrade a stud wall to an acoustic stud wall (Up to 17db)
• Upgrading an existing stud wall can be a great space saver, requiring little extra space to be consumed by having a full acoustic wall. By removing one side of the original stud wall plasterboard, the original stud wall can be used in conjunction with various products all designed to add their own damping properties.
• By fixing U rails to the existing stud frame work, once one side of plasterboard is removed, a double boarded acoustic side can be attached to the rails giving around 12db of damping to the new wall. To increase this to around 17db, the use of acoustic mineral wool between batons and acoustic membrane over frame, can be added before fixing the new double board acoustic layer.
• The spring like action of the U rails, in addition to the mineral wool, acoustic membrane and double board acoustic layer, offer a great 17db improvement to an existing stud wall, without imposing on any extra space into the room.

Acoustic walls for all party wall types (Up to 22db)
• Unlike acoustic panels, an acoustic wall can be used in conjunction with party walls constructed of any type of material, offering a solution for stud, wood, breeze block and brick construction.
• Construction of an acoustic wall is completely down to the level of acoustic damping that is required, using an array of products all designed to add their own levels of damping. The bare minimum required for an acoustic wall would be wall batons, U rails and acoustic plasterboard, used to step the new acoustic wall away from the transmission wall, offering a spring like action to the wall to prevent radiant transmission.
• In addition to the acoustic wall, which offers around 14db – 16db of acoustic damping, by means of U rails and acoustic plasterboard, acoustic mineral wool and acoustic membrane can also be added for a further 5db — 6db improvement. By filling the gaps between the wall batons with acoustic mineral wool, and laying the extra lining of acoustic membrane, you should be able to achieve an approx total of 22db total damping.

Additional acoustic stud wall (Up to 30db)
• One of the most extreme methods of airborne noise damping for walls, is to introduce a second wall slightly in front of the original wall. Whilst this is the most extreme giving the best results, lab our, materials, space and cost are all a significant factor, making it a very expensive solution that will have a detrimental effect on your space.
• Think of this like a double wall being separated by an air cavity, where the first wall is the original and the second is a stud wall spaced approx 25mm away from the original wall to provide the cavity.
• First a stud wall frame is created, suitably spaced from the original wall to provide the cavity required. In between each baton in the new stud wall, the space is filled with acoustic mineral wool. Next comes an acoustic membrane overlay, fixed to the batons, covering the entire stud wall frame and fixed at the batons. Next comes U rails, offering the spring type action necessary to separate the acoustic plaster board from the stud wall frame. The final addition sees a double boarded acoustic plasterboard layer, fixed directly to the U rails.
• The additional acoustic wall, whilst carrying extra cost and limiting space requirements, is one of the most extreme solutions available, giving a standard flat wall finish. Whilst there are other solutions available for extreme reduction, this solution provides the best reduction of airborne noise whilst maintaining a flat plastered finish.

Airborne acoustic damping (Up to 25db)
• For effective methods of damping airborne acoustic noise, a combination of various materials can be used, all offering a varying degree of damping properties. When combined the total effect can be approximately 25db.
• First acoustic mineral wool can be utilized under the boards, this normally comes in a thickness of around 100mm and of sufficient density to offer around 12db of damping to airborne acoustics. It is laid directly onto the top side of the ceiling acting like an insulator.
• Second acoustic plasterboard can be used, fixed to batons by acoustic mastic, offering a spring type action to the plasterboard to prevent radiant acoustic energy passing into the board. Either single or double plasterboard can be used in order to cut down further and improve damping around 5db to 8db.
• Finally, an acoustic membrane can be utilized draped across the whole floor and fixed in place to floor joists, before refitting floorboards. The addition of the acoustic membrane can offer 4db – 5db of additional protection.
• Once all flooring has been replaced, acoustic mastic is used to seal all gaps in between floor boards to ensure there are no gaps where noise injection can take place. The total solution offers a damping of around 25db, if all materials listed above are utilized.

Impact acoustic damping.
• In addition to airborne noise solutions, there are a number of solutions available more directly targeted at damping down impact sound caused by vibrations in the buildings structure. Whilst ambient noise can be confronted by using methods of damping the noise, impact noise can be a more serious issue. Typically damping is ineffective against impact noise, with the only true solution being separation from the buildings structure.
• Impact noise is created when heavy vibrations in the buildings structure occurs, either through impact of objects against the buildings structure or the floor (doors, nearby construction), or by conversion of airborne noise into the buildings structure (bars, pubs, clubs). Whilst the two causes are both different, they are cause the same issue, vibrations in the structure carried through the building via radiant energy.

Floating Floor Hangers (Up to 20db)
• The first of two solutions to create a floating floor, hangers offer a good solution to impact noise, with the added benefit of some protection against airborne noise too. Hangers are placed on each joist, sitting on an acoustic strip to create a cushion that counter acts the vibrations past through the joists. Acoustic plaster board can then be applied, sitting on the hangers to offer a further protection against airborne noise. On top of the plasterboard, the original floor may be re-fitted, using acoustic mastic between each board to prevent leakage of airborne noise.
• This offers a great solution to impact and airborne noise, approx 20db of acoustic damping can be achieved whilst ensuring you do not raise the original floor by too much. This is the perfect solution for a floating floor in areas constrained by the height of the floor.

Floating Floor Joist Strips (Up to 20db)
• Whilst hangers are a good solution to a floating floor, giving you the ability to re-use your old floor boards and reducing height of your new floor, they can be very lab our intensive. A more simple solution is to utilize joist strips, these can be laid on the joists to create the cushion required to stop vibrations, simply and easily.
• Due to the nature of joist strips, giving no flat surface to lay your floor boards, it is recommended to fit a new one piece floating floor, instead of re-using your original boards. This solution is quicker than using hangers, but also results in your new floor gaining more height. Where height of your new floor is an issue, hangers would be recommended over this solution.

Acoustic Mats.
• For a more cost effective solution to floating floors, a range of acoustic mats is available. These offer a simple solution to impact and airborne noise damping, and when used in conjunction with such things as acoustic plasterboard and acoustic mineral wool, become a nice cheap alternative to floating floors.
• Due to the nature of acoustic mats, being laid on top of existing floorboards, height can become an issue, increasing the height of your floor considerably. In addition to this, it is recommended to only use acoustic mats alongside other products. Mats alone will not be sufficient for preventing acoustic noise.

Floating Ceiling U rails (Up to 16db)
• Where height constraints are an issue, the U rail solution is possibly the best course of action. Being the least obtrusive of all the floating ceiling solutions it can offer damping of up to 16db, by separating the new ceiling from the joist. Although the least obtrusive, it can be the most messy, requiring the old ceiling to be removed.
• For extra damping, a layer of acoustic mineral wool is filled into the cavity between the joist to further improve on the damping of the new ceiling.
• U rails can be fitted at intervals to the joists, providing a way to fix the new ceiling to the joists, while allowing a springy action to be retained by the U rails. A double acoustic plasterboard layer can then be attached and skimmed, Sealing any edges with acoustic mastic to keep the new ceiling separated from the walls.

Floating Ceiling Hangers (Up to 20db)
• Whilst being slightly more intrusive than the U rails, hangers can offer a more improved damping affect do to the hangers being completely separated, hanger in a special bracket. Using hangers can mean less mess, but in return offers a more complex build, increasing the lab our intensity, by adding an additional framework to be built.
• Leaving the old ceiling in place, hanger brackets are placed at intervals. A new framework is then built and hung from the brackets using the acoustic hangers. Onto this framework, a new double layer of acoustic plasterboard is fitted and skimmed. Finally to keep the new floating ceiling separated from the building walls, acoustic mastic is used to seal the ceiling to the walls.

Additional Floating Ceiling (25db and up)
• For maximum damping, the ultimate solution is to have a second ceiling, dropped suitably from the original and offering a second barrier to stop acoustic noise. A new framework of joists is installed typically around 10 inches lower than the original ceiling, making this the most extreme solution you can find. One major drawback however, can be the reduction in ceiling height, making this solution unachievable in some circumstances.
• Once the new framework has been built, the joist cavity is filled with acoustic mineral wool, offering the good level of damping. U rails are then used on the new joist framework, hanger a double layer of acoustic plasterboard skimmed and sealed at the edges with acoustic mastic. AIMCOUSTIC FLOOR SLAB
