Accolade Metallic Alloy Ribbon
37 questionsHow thick is the amorphous ribbon?
The recovered specification describes the bare amorphous ribbon as 25 microns thick, or 0.025mm. Confirm the complete mat thickness on the current product datasheet.
Is the amorphous ribbon insulated?
The heating element is enclosed between insulating layers, but its current electrical classification and required additional protection must be confirmed from the exact product datasheet and project design.
How quickly do the mats reach working temperature?
Warm-up time depends on output, coverage, insulation, subfloor, floor finish, room heat loss and controls. The archived fixed-time claim has been withdrawn pending current performance data.
Do the mats come in different sizes?
Available mat dimensions and fixing methods must be confirmed from the current catalogue and installation guide. Never cut, fold or improvise the heating element to make a size fit.
What is a “Primary Heat Source” product?
Whether a system can act as the only heat source depends on a room-specific heat-loss calculation, the available heated area and the proposed floor build-up.
What is a “secondary heat source” product?
A supplementary system contributes heat alongside another source. Its suitability and output still need to be checked against the room heat loss.
Will the heat mats generate sufficient heat to be a primary heat source?
Do not rely on a simple coverage percentage. A competent designer should compare the specified system output with a current room heat-loss calculation.
Can I fit the UFH myself?
Only work specifically allowed by the current installation guide should be undertaken by a competent installer. Electrical design, connections, testing and commissioning require an appropriately qualified electrician.
What is the warranty period?
The archived site contains conflicting warranty periods. Current warranty scope, duration, exclusions and supplier identity must be confirmed in writing before purchase.
How is the power supplied to the system?
Supply arrangement, protective devices, cable sizing, isolation and controls must be designed for the actual load and current regulations by a qualified electrician.
How is each room’s temperature controlled?
Zoning and thermostat quantity should be selected for the building use, heat-loss design, system load and chosen control strategy.
Must I have an RCD (circuit breaker) fitted to the system?
Required electrical protection must be determined from the current product instructions, circuit design and applicable regulations. A qualified electrician should specify, test and document it.
Where can I get more information?
Use the documents and videos in the rebuilt resource centre as archived references, then confirm current information through the contact details on this site.
Can I fold or cut the mat?
Do not cut, fold, crease or modify a heating element unless the exact current product instructions expressly allow it. Obtain the correct mat layout and sizes before fitting.
Can the mats overlap each other on the floor?
Do not overlap heat mats. Required separation and edge clearances must follow the exact current product guide and approved layout rather than the archived fixed dimension.
Should the mats cover the whole floor area?
Coverage, edge clearances and excluded areas must follow the project layout and current installation guide. They vary with room heat loss and fixed objects.
Can I lay mats under my shower tray/WC/bath?
Do not place heating elements beneath fixed items unless the current project design expressly permits it. Trapped heat can damage the floor or system.
Can I use any carpet underlay when fitting UFH in my lounge?
Carpet and underlay must be approved for underfloor heating, and their combined thermal resistance must remain within both the floor manufacturer’s and current heating-system limits.
Do I still need to lay acoustic insulation with laminate flooring?
Every layer above the heat mat affects heat transfer. Confirm the combined underlay, acoustic and floor-finish build-up with both manufacturers before fitting.
Can I extend the cold leads (cables) on my mats?
Do not extend, joint or substitute cold leads unless the current manufacturer instructions expressly permit the method and cable. Electrical work must be completed and tested by a qualified electrician.
Can the mats be connected in series rather than in parallel?
Connect heat mats only in the configuration shown in the current wiring design and product instructions. Do not improvise series or parallel connections.
Why should the system be tested BEFORE fitting the floor covering?
Required resistance and insulation tests help identify transport or installation damage before the system is concealed. Record results at every stage stated in the current guide.
Can I walk on the mats as I am fitting them?
Keep traffic to a minimum, protect laid mats from tools and sharp debris, and follow the current guide. Inspect and test again if damage is suspected.
Can I use the mats outside on my patio/driveway?
Indoor heat mats are not outdoor products. Outdoor applications need the correctly rated ribbon, controls, protection and project-specific design.
Why isn’t the system laid in a screed as most other UFH systems are?
Some compatible build-ups position the heat mat close to the finished floor rather than inside a deep screed. The correct layer sequence depends on the product, substrate and floor finish.
My mats have ridges/folds in them when they are laid – is this okay?
Do not energise, stretch or force a creased mat based on this archived answer. Isolate it, inspect for damage and follow the current manufacturer guidance before installation.
What are “Grounding Nets” and when should I use them?
The archive describes a conductive mesh connected to protective earth. Its necessity, position and connection must be determined from current product instructions and electrical regulations for the exact location.
Can I use "Dot & Dab" tiling method for laying tiles above the UFH?
A tiled build-up normally needs continuous contact without heat-trapping voids. Use only the adhesive coverage and layer sequence approved in the current heating and tile-system instructions.
Can the mats be repaired?
A suspected fault must be located, assessed and tested by an appropriately qualified person. Use only a current, approved repair method and retain the test record.
Can I control other electrical items from the fused spur for my UFH?
Circuit arrangement and permitted connected loads are matters for the electrical design. Do not add other equipment to a heating supply without the qualified designer’s approval.
Can I really reduce my heating by 2 – 4 degrees compared to “traditional” heating?
Comfort settings and energy use vary with fabric heat loss, controls, occupancy, weather and floor construction. The archived temperature-saving and health claims have been withdrawn pending evidence review.
I’m installing 18mm solid wood flooring – can I still use UFH below this?
Use underfloor heating only where the timber and floor-system manufacturers approve the complete build-up and temperature limit. Thick timber can reduce response and output.
Can I put my sofa and other large furniture items on a floor with UFH?
Plan mat-free areas below furniture or objects that could trap heat. Follow the floor and heating manufacturers’ clearance and temperature requirements.
I’m considering a vinyl floorcovering for my kitchen – can I still use UFH?
Vinyl and LVT can require a protective levelling layer and strict temperature limits. Follow the current heating, compound and flooring manufacturers’ compatible build-up.
Can I install UFH in my bathroom/shower/cloakroom?
Heating can be designed for bathrooms and other special locations only with suitable equipment, zoning and electrical protection under current regulations.
How do I secure the mats to the insulation material?
Use only the fixing materials and method allowed by the current guide. Fixings must not pierce, crease or otherwise damage the heating element.
What are the advantages over a "wet" underfloor heating system?
Electric ribbon and hydronic systems have different build-up, response, energy-source and control characteristics. Costs and performance should be compared for the actual building rather than using the archived claims.

Accolade insulation material
10 questionsWhat type of carpet underlay should I use?
Choose a carpet and underlay combination approved for underfloor heating and within the current maximum thermal-resistance limits of both the heating and flooring manufacturers.
What are the different types of insulation?
The archive describes flexible roll insulation for suitable floating floors and rigid board for suitable bonded or levelled floors. Confirm current availability and compatibility from the specification sheets.
Can I install the UFH system without insulation?
Suitable insulation is normally part of the specified system for heat direction and mat protection. Follow the current project build-up; do not omit or substitute layers without written approval.
Can I use flexible insulation below a ceramic tile floor?
Use only an insulation board and tiled build-up approved by the heating, insulation, adhesive and tile manufacturers. Flexible roll products are not generally intended to support bonded tile finishes.
Won’t the solid board insulation “give” below my ceramic tiles?
The archived load claim has been withdrawn pending verification. Obtain the current compressive-strength datasheet and have the complete floor build-up checked for the design load.
How should I secure the solid insulation to my floor?
Prepare and bond rigid insulation exactly as required by its current datasheet and the chosen floor system, using compatible materials and curing times.
What brand of flexible tile adhesive should I use?
No adhesive brand is endorsed by this rebuild. Use a product whose manufacturer confirms compatibility with the substrate, insulation, underfloor heating and final floor finish.
How should I secure the flexible insulation to my floor?
The permitted fixing method depends on the subfloor and current insulation datasheet. Never use a fixing that could damage concealed services or the heating system.
Why is insulation just 7mm thick when many systems require 50mm+?
Insulation performance cannot be judged from thickness alone. Compare verified thermal resistance, compressive strength and compatibility for the complete floor build-up.
My conservatory has insulation under the concrete base – won’t that be sufficient?
Insulation below a structural slab does not necessarily replace a suitable layer directly beneath the heating system. A designer should assess the full construction and downward heat loss.
