AIMCoustic Floor Slab
Thermal and acoustic insulation for floor constructions.
PRODUCT
High Density Tissue Faced Rockwool Floor Slab (with optional rebated edges).
APPLICATIONS
AIMCoustic Floor Slab may be used with ground
bearing slabs, timber joist, beam and block or
concrete suspended floors.
AIMCoustic Floor Slab may be used under a fine
concrete screed in ‘wet’ construction, or under
flooring grade chipboard in ‘dry’ construction.
The tissue facing allows the laying of wet screed
directly to AIMCoustic Floor Slab without building
paper. Rebated edges, if chosen, help prevent grout
leakage and thermal/ acoustic bridging.
FEATURES
- High Compressive strength.
- Good thermal insulation properties.
- Excellent acoustic insulation properties.
- Euroclass A1 Non combustible solution.
BENEFITS
- Helps meet the thermal requirements of ground and upper floors.
- Helps deliver good acoustic insulation performance upper floors.
- Will not contribute to a fire within the building.
- Easy to install

TECHNICAL INFORMATION
THERMAL PERFORMANCE
U value calculations in accordance with BS EN ISO 6946 are available upon request.
FIRE PERFORMANCE
AIM AIMCoustic Floor Slabs are manufactured
from Rockwool stone wool which is inherently noncombustible and is rated A1 when tested to EN
13501-1 classification using test data from reaction to
fire test.
ACOUSTIC PERFORMANCE
The density and fibre orientation of AIM AIMCoustic
Floor Slabs means that they are especially effective
at absorbing vibration, or impact, based sound. They
are suitable for use in achieving Part E (Sound) of the
Building Regulations in separating floors, floating floor
solutions and many other such constructions.

INSTALLATION GUIDELINES
The sub floor must be structurally sound and level. AIMCoustic Floor Slab will accommodate minor imperfections of flatness and burrs of concrete but for more major unevenness, it will be necessary to lay a levelling screed, or sheathing ply over timber joists.
Damp Proof Membrane
A DPM is required under AIMCoustic Floor Slab when laid on ground floors or where the substrate hasn’t fully dried.
Perimeter Strip
The perimeter of the floor should be lined with a polyethylene (PE) perimeter strip, to allow for acoustic isolation and expansion the surface layer. The depth of the PE perimeter strip is to be the thickness of AIMCoustic Floor Slab plus the thickness of surface layer (i.e. screed or chipboard).
Laying AIMCoustic Floor Slab
Boards should be laid lengthwise to the longest wall (having removed the rebated edge where the slab abuts the wall), with staggered joints, tissue face upwards.
Chipboard Surface Layer
Flooring Grade P5 T&G Chipboard should be laid with
staggered joints, the long edges being parallel with
the longest wall. All tongue and groove joints should
be glued with PVA adhesive.
Temporary wedges should be used at the perimeter
to hold the tongue and groove joints tight, whilst
the adhesive sets. When the adhesive has set,
the wedges must be removed and damage to the
Isolation Strip made good.
At door thresholds, or where a change in floor
construction occurs, a timber batten of the same
thickness as the insulation should be inserted to
reinforce the edge. Skirting boards should finish
approximately 5mm above floor level and be isolated
from the chipboard with PE perimeter strip.
Screeded Surface Layer
The screed should be of fine concrete and a minimum depth of 65mm (75mm for nondomestic applications). A light wire mesh is required in the screed. Joints in the AIMCoustic Floor Slab should be taped or rebated edge products used. Alternatively, a Vapour Control Layer could be introduced above the AIMCoustic Floor Slab. An upstand of PE perimeter strip is required at perimeters.
ITEMS REQUIRED FOR INSTALLATION
- PPE abrasion resistant gloves
- PPE impact resistant goggles
- RPE dust mask
STORAGE
Products are supplied on wooden pallets with edge protection and a shower proof hood. Products should be stored away from the elements until ready for installation.
MAINTENANCE
This product does not contain moving parts and, if undisturbed, requires no routine inspections or maintenance.
DURABILITY
AIMCoustic Floor Slabs are chemically inert, will not sustain vermin and do not encourage the growth of rot, fungi, moulds or bacteria. They are compatible with all normal building materials. Rockwool stone wool has been proven in service for over 60 years, in a wide range of climates and degrees of exposure. It will generally perform effectively for the lifetime of the building, plant or structure.
HEALTH & SAFETY
Insulation products supplied by AIM are considered
to be inert articles and as such are exempt from
requirements to provide a Safety Data Sheet.
A Product Safety and Handling Information Sheet is
available upon request.
