Solutions FLOOR HEIGHTS, RESILIENT LAYER OPTIONS AND INSULATION The acoustic underlays and insulation shown below can be used with 23mm high-density routed gypsum AcoustiPanel™14: The height of the specified floor finish should also be taken into account when calculating overall floor height build-up.

Foam resilient layers are not suitable for use with AcoustiPanel™14.

Resilient layer – supplied by Nu-Heat for installation below the routed AcoustiPanel™14. IsoRubber-UFH-NH is a 5mm thick acoustic resilient layer, produced especially for Nu-Heat

by Thermal Economics. All test data is based upon this.

However, if the contract requires, then this product may be substituted with Thermal Economic’s 6mm IsoRubber Base.

25mm XPS insulation – AP14 has been tested with a 25mm thick extruded polystyrene (XPS) insulation with a compressive strength of 200kPa (Knauf Polyfoam C200SE).

Where additional insulation is specified it must be of the same height and of an equivalent (or greater) kPa value. It should be installed below the IsoRubber-UFH-NH base layer.

Overall height build-up with 25mm XPS insulation: 5mm + 25mm + 23mm + 3mm = 56mm

Design considerations MANIFOLDS Manifolds are required to control the underfloor heating. AcoustiPanel™14 with a single manifold will typically cover up to 100m2 but this depends largely on the layout of the floor area in relation to the position of the manifold.

Multiple tube runs can take up a considerable floor area when running from several room zones, making it difficult to design a sensible layout. This can easily be overcome by positioning the manifold in a central location or by installing areas of castellated panel that can accommodate greater numbers of pipe runs in a small area. Your Nu-Heat Design Engineer will discuss the layout with you if this situation arises.

A single manifold will typically cover up to 100m2

Bunching of pipes in the area around the manifold should be kept to a minimum.

The CAD pipe layout will illustrate the routes to follow.

PANEL CONFIGURATIONS AcoustiPanel™14 offers a fully tailored design with 7 panel options to allow optimal coverage for heating layouts and pipework back to the manifold.

Use the CAD panel layout drawing supplied by Nu-Heat to mark out areas where routed panels or castellated panel have been specified. Full details are provided in the AcoustiPanel™14 Installation Instructions.

The detailed CAD drawings supplied by Nu-Heat will clearly indicate the type of panel to use in each area and the direction in which to install it.

Panel configurations The AcoustiPanel™14 solution is made up of several elements for a truly bespoke design:

outed straight panel R Straight panels are used to cover the majority of the floor; at the end of each length, a routed turn panel is used to create a smooth transition into the next pipe run. Supplied as 1200 x 600mm and 600 x 600mm variants.

Routed turns panel – 150/200mm multi-turns An oval pattern with spacing of 200mm x 150mm, for use in small floor areas and rooms with complex shapes.

Routed turns panel – double return 200mm spacing for use at one end of a room with a double routed pattern.

Routed turns panel – triple return 200mm spacing for use at one end of a room with a triple routed pattern.

Routed turns panel– 100mm circles 100mm x 100mm spacing for use in halls where multiple runs of tube must be accommodated in a small area.

Castellated panel Castellated panel may be specified immediately adjacent to the manifold and areas with very tight pipe spacing.

Your Nu-Heat Design Engineer will always contact you to discuss the options in this situation.

Installation INSTALLATION CONTRACTOR OPTIONS The installation process for AcoustiPanel™14 is straightforward and you may wish to use your normal contractor. Alternatively, Nu-Heat has a network of Trained Flooring Contractors who will be happy to work with you on the project – please contact us for details of those working in your area.

INSTALLATION CONSIDERATIONS Sub-floors should be level to SR2 standard (it is acceptable to use a floor leveller to achieve this if required) and structurally sound.

With any acoustic floor cassette the acoustic flanking treatment can have a big impact on performance.

5mm acoustic IsoRubber-UFH-NH base layer This high performance rubber base isolates the floor from any potential acoustic bridge by effectively tanking the entire floor.

Panel laying method Mechanical fixings are not required with AcoustiPanel™14 – pre-routed panels are just glued together along the tongue and groove edge and free floated over the IsoRubber-UFH-NH base layer. The castellated panel that may be specified in small areas for complex installations has a self-adhesive backing which is stuck directly to the IsoRubber-UFH-NH base layer.

3mm skim coat All areas of AcoustiPanel™14 are finished with a 3mm skim coat of self-levelling compound to give a consistent, flat surface beneath the floor covering. This is also an opportunity to align levels between the hall and the room zones, which is especially important where floor coverings are continuous.

The surface of the routed panel is primed before grouting the panels. The grout dries very quickly and is followed by the skim coat.

The skim coat dries to take foot traffic after approximately 8 hours/overnight and floor finishes can be fitted after just 72 hours, meaning minimal disruption to the build schedule.

All common floor coverings can be used with AcoustiPanel™14 – the installation manual supplied will give detailed instructions for fitting those listed below. For a comprehensive list of suitable floor coverings please visit www.nu-heat.co.uk.

• C eramic tiles Ceramic tile and natural stone floor finishes are a perfect partner for warm water underfloor heating – conducting heat efficiently and effectively in all areas. Standard or large-format tiles can be used with AcoustiPanel™14.

• Natural stone Like ceramic, stone is an excellent conductor of heat, making it an ideal finish for underfloor heating. Both soft and hard stone finishes can be used.

• Engineered timber The high heat outputs achieved by AcoustiPanel™14 mean that engineered timber rather than solid hardwood is recommended. This is made up of layers laminated together with the wood grain running in opposite directions in each layer, making it inherently stable.

• Vinyl and laminates Vinyl and laminate can provide a seamless finish and provide a hardwearing floor finish. Both conduct heat well and are suitable for use with AcoustiPanel™14.

• Carpet and underlay (max. 2.5 tog) It makes sense to choose carpet and underlay that will give good performance when used with underfloor heating, so the combined value of the carpet and underlay should not exceed 2.5 tog. Good manufacturers will have technical information on their products available to customers.

• Microtop and polished screeds Microtop screed is a thin polymer modified coating that looks like polished concrete. Polished screed is a cement based overlay that can be diamond polished. Both offer excellent heat transfer when used with AcoustiPanel™14.

• Resin AcoustiPanel™14 provides a level, cementitious, mirror finish ready for direct application of the resin manufacturer’s recommended primer followed by the resin layer.

Fixing floor coverings FIXING CERAMIC TILES AND STONE OVER ACOUSTIPANEL™14 De-coupling layer Whilst Nu-Heat usually recommends the use of a de-coupling layer below tiles and stone, it is the responsibilty of the flooring contractor to follow the recommendations of the flooring supplier in this regard.

Standard and large-format tile/hard stone finishes Where necessary, prime the surface using the product recommended by the flooring supplier or Mapei EcoPrim T. Fix the tiles using a continuous, trowel-applied bed of good quality, flexible adhesive with no air gaps.

Soft stone: (limestone, marble, terrazzo, etc.)

Where required, the surface of the AcoustiPanel™14 skim coat should be primed using the product recommended by the flooring supplier or EcoPrim T. Fix the stone using a flexible adhesive and grout recommended by the supplier.

The acoustic flanking strip supplied acts as an expansion gap around all perimeter walls to allow the floor to expand and contract as required; this is usually hidden by the skirting board or perimeter tile upstand.

Notes: The above recommendations would apply to any stone or tile floor regardless of whether UFH was present or not.

To ensure suitability for stone and ceramic finishes, the architect or specifier must ensure that the sub-floor provides a stable, level base, before AcoustiPanel™14 is fitted.

Stone/tile Flexible adhesive De-coupling layer Flexible adhesive Floor primer, e.g. Mapei Eco Prim T AcoustiPanel™14 with skim coat and IsoRubber-UFH-NH Sub-floor (level to SR2 / with deflection to suit the floor covering

FIXING ENGINEERED HARDWOODS OVER ACOUSTIPANEL™14 Engineered hardwood floor finishes can either be glued directly to the floor surface using the supplier’s recommended adhesive or, alternatively, glued and butt-jointed then free-floated over the floor surface.

The engineered timber finish does not need to be overly thick because the AcoustiPanel™14 below provides continuous support – Nu-Heat recommends a maximum thickness of 18mm, but 14–15mm is preferred, as this provides less thermal resistance and higher heat outputs from the UFH.

Engineered timber (glue or free-float) AcoustiPanel™14 with skim coat and IsoRubber-UFH-NH Sub-floor (level to SR2 / with deflection to suit the floor covering

SOLID HARDWOOD Nu-Heat does not recommend the use of solid hardwood floors when used in conjunction with the AcoustiPanel™14 underfloor heating system due to the high heat outputs generated.

CARPET & UNDERLAY The surface of the 3mm skim coat will provide a flat surface for carpets. Use an underlay recommended for use with underfloor heating in conjunction with hessian-backed carpet with a combined tog value no greater than 2.5.

Where gripper rod is to be used it should be glued down, not nailed. Alternatively glue the carpet down using an appropriate adhesive as recommended by the manufacturer.

Fixing floor coverings LINOLEUM, VINYL, AMTICO, KARNDEAN, etc.

Underfloor heating can be used effectively with linoleum (e.g. Marmoleum) and vinyl (e.g. Amtico, Karndean, etc.) as long as the floor temperature is regulated so that it does not exceed (typically) 27˚C. Nu-Heat can supply a thermostat that can both control the room temperature and top-limit the floor temperature. Where alternative system control is being supplied by a third-party, it should incorporate floor temperature limiting.

The surface of the skim coat will provide a perfectly flat surface for linoleum or vinyl floor coverings. Floor leveller can be used to adjust floor heights to match those in adjoining areas where necessary. This is normal practice and is carried out by the flooring contractor.

Always use the manufacturer’s recommended adhesive when fixing linoleum and vinyl floor coverings.

Floor leveller can be used to provide a smooth transition between floor finishes.

MICROTOP & POLISHED CONCRETE Micro-top polished concrete, also known as micro-cement, is a thin coat polymer modified cement based coating which is available in a variety of colours and textures. It is UV stable and can be used in high traffic areas.

Micro-top is highly resistant to abrasion and water; it also has flexural and compressive properties that make it a suitable product for use over UFH. Like AcoustiPanel™14, micro-top is a good solution for construction projects with tight deadlines.

Always refer to the manufacturer’s information for suitability of use with underfloor heating and recommended installation methods.

Microtop polished concrete coating (0.5–3mm): A polymer modified coating applied at 0.5mm to 3mm that looks like polished concrete.

Polished concrete overlays (10–40mm): A cement based overlay applied at 10mm to 40mm that can be diamond polished.

• Prime the skim coat with EcoPrim T (see Nu-Heat information sheet) or primer recommended by the supplier and allow to dry.

• Prime the skim coat with EcoPrim T (see Nu-Heat information sheet) or primer recommended by the supplier and allow to dry before applying the overlay.

• If necessary, cover with 10mm of Latexplan Trade levelling compound, or equivalent, to provide a mirror surface ideal for the final micro-top coating (see Nu-Heat information sheet).

SYNTHETIC RESIN Laying synthetic resin floor finishes over AcoustiPanel™14 Synthetic resin finishes typically have a thickness of 0.15mm to 6mm. The type and thickness of the resin used relates to the location in which they are to be laid, the durability required and the volume of foot traffic that they will encounter.

Synthetic resin finishes can be used with AcoustiPanel™14 with simple floor preparation: • Prime the skim coat with EcoPrim T (see Nu-Heat information sheet) or primer recommended by the resin supplier and allow to dry before laying the resin finish.

Underfloor heating and resin • The floor heating should be tested and working before installation of the resin.

• The floor heating should have been switched off 48 hours prior to installation.

• Check that the moisture content of the self-levelling skim coat meets resin manufacturer’s guidelines before applying primer or resin.

• The floor heating should not be switched on for up to 7 days depending on conditions and manufacturer’s recommendations.

Floor temperature control Some suppliers recommend a maximum floor surface temperature for their floor coverings, especially timber and vinyl. Nu-Heat can supply a room thermostat that controls room temperature and top-limits the floor temperature (see separate technical guide for installing floor temperature top-limiting sensors). The sensor should be fitted as close to the upper surface of the floor as practicable.

Where alternative system control is being supplied by a third-party, it should incorporate floor temperature limiting.

Where specified, fit the floor temperature sensor as close to the upper surface of the floor as practicable.
