Underlaminate Heating Mats
A UK manufactured fully earthed system designed to be used beneath quality floating laminate and engineered floor boards without the requirement for covering with levelling compounds. The mats can provide sole source heating in well-insulated rooms, and floor warming in less well-insulated situations. The mats are quick to install and can be 'cut and turned' like a conventional undertile heating mat. When used with a Heat Mat thermostat they provide a fast reacting and economic to use heating system.
Underlaminate Mat Features
- Designed to provide floor warming in all rooms, and sole source heating in well-insulated areas
- Ideal for use beneath floating laminate and engineered floor boards of up to 18mm thickness, using the traditional tongue and groove/click system as the joining mechanism
- Integrated earth shield within the cable (unlike carbon films), allowing safe installation in wet areas including bathrooms
- Dual conductor system, so only one power lead per mat
- Provides excellent insulation properties and sound deadening when used with our 6mm insulation board
- No requirement to cover the mats with an additional levelling compound or moisture barrier, saving build height and costs
- Fail-safe cable design ensures a damaged or overheating cable will cut-out rather than continue to heat, as with alternative systems such as fluoropolymer insulated underlaminate heaters or carbon film systems
- Pre-spaced heating cable for speedy installation and uniform heat output
- Simple cut and turn design offers many advantages over panel systems and speeds up installation
- Aluminium heat dissipation layer ensures an even heat spread with no cold spots
- With its integrated earth, it is safe for all rooms including bathrooms
- A large range of standard sizes which can be mixed and matched to ensure a perfect fit
- Supplied with a Lifetime Warranty
- 17th Edition compliant without any additional earthing required
- Made in the UK
Selecting the correct sized heating mats
To start with you will need to calculate the Free Floor Area (FFA). To calculate the FFA you should measure the room to find out the total floor area. You should then subtract from this any areas where kitchen or bathroom furniture will be placed, or where furniture without an air gap beneath it will be positioned. Once you have taken off these areas you have your FFA. For rooms of up to 8m2, we recommend choosing a combination of heating mats which cover roughly 90% of your FFA, and for rooms larger than 8m2 we recommend covering around 95% of the FFA.
Combining multiple units
130W heating mats are designed to be laid together with other 130W mats to ensure the perfect fit every time. The mats are wired into the thermostat or junction box in parallel, but it is important to ensure that any other mats used in the same room are also rated at 130W/m2.
Simple and speedy installation
Heat Mat electric underlaminate system mats are incredibly simple to install and in large areas can take just half as long to fit as a panel system. The mats can be cut and turned to ensure they fit the room perfectly, and for particularly complicated areas the cable can be stripped from the mat and laid as a loose cable. Aluminium tape is used to cover any loose cables and also to secure the mats.
Sub-floor surfaces and insulation board
Heat Mat's XPS foam underlaminate insulation (which must be installed beneath the system) offers a good trade-off between build height, cost and insulation value. For particularly badly insulated areas we recommend laying Heat Mat structural thermal insulation boards beneath the 6mm XPS insulation layer. The foam insulation ensures the heat spreads evenly accross the floor.
Designed specifically for floating floors
This system is designed specifically for use beneath floating laminate and engineered board floors of up to 18mm thick. You should always check with the supplier of your flooring that it is suitable for use with electric underfloor heating directly beneath it.
There is now a new type of laminate flooring on the market that uses a unique kind of connection, often called a ‘V Groove’ or ‘smart fitting mechanism’. This mechanism uses a small plastic element to lock the boards together at each end which allows floors to be installed far faster than a conventional laminate floor. When our ULS system or other similar products are used with this type of laminate, the flooring can experience significant movement and the end joints of the boards can be damaged, leading to further movement of the floor. We believe that these floors are therefore not compatible with Heat Mat’s ULS range of heating.
Heat Mat’s ULS heating system is not suitable for flooring of any thickness using this new style fitting mechanism. These boards usually have a plastic insert within the end joint which locks the board into place (the red section shown in the diagram below). These boards do not appear to be suitable for installation directly on top of underfloor heating systems and soft insulation; they require an alternative underfloor heating system which needs to be covered with levelling compound or screed first.
Heat Mat’s ULS is suitable for use with 8-18mm thick engineered board floors with a traditional tongue and groove click system. It is also suitable for use with laminate floors of 8-18mm thickness that feature traditional tongue and groove/click system joints, if this type of joint is also used at the end of each board (fully interlocking joints).
130W heating mats are almost 100% efficient at converting electricity into heat and they can easily be powered by locally generated electricity from either photovoltaic or wind power sources. When used with Heat Mat’s NGT thermostat they form an energy-efficient system, and they are also suitable for integration into a home/building automation system.
Safe and guaranteed
Heat Mat's underlaminate system mats are manufactured in the UK and supplied with a Lifetime Warranty. They are the only system currently on the UK market to combine a full earth shield and temperature limited fail-safe cable design with an ability to be laid without requiring a levelling compound or screed.
