Description

Brit Heat Mat is a decoupling polypropylene membrane with a cut-back stud structure and an anchoring fleece laminated to the underside. It has rounded square shaped reliefs designed to secure electric heating cables up to 4.5mm thickness into place within its pre-grooved channels without the use of clips or fasteners. It is a quick installation solution designed to be installed directly beneath tile, porcelain, stone, slate, marble etc.

Installation:

Apply a 4mm bed of BritFlex S1 flexible tile adhesive to the substrate. Ensure the matting is anchored fleeced side down and is fully embedded into the tile adhesive to ensure a mechanical bond of the fabric in the adhesive. Allow the adhesive to cure before over laying with tile coverings.

Key Benefits:

  • Decoupling Crack Isolation
  • Vapour Management
  • Waterproofing
  • Flexible Heating Zone Selection
  • Cost and Time Saving Installation
  • Support Load Distribution

Built for Fast Installation & Cable Protection

This advanced polypropylene membrane features a unique "cut-back stud" structure designed to hold electric heating cables (up to 4.5mm) securely in place without the need for clips or tape. We have engineered it with an anchoring fleece underside to provide mechanical bonding, decoupling your tiles from the substrate to prevent cracking caused by lateral movement.

Words From Our Valued Clients

4.8/5

Cuts installation time in half

I used to spend hours taping heating wires to the floor. With this mat, you just walk the wire into the grooves and press it down. It cuts installation time in half.

Martin L. (Electrical Contractor)

Not a single cracked tile

My kitchen floor had hairline cracks in the screed. My tiler insisted on using this to 'decouple' the tiles. Two years later, heating is on full blast and not a single cracked tile.

Sarah Jenkins

Better value than the big brands

I've used the big brand orange matting for years, but the Brit Heat Mat is just as good quality and much better value. The studs hold the wire really firmly.

ProTiling Solutions

Rock solid load support

I was worried about heavy appliances on top of a plastic mat, but once the adhesive fills the studs, it's rock solid. The load support is excellent.

Davey G.

Perfect wire spacing every time

The studs act as a guide, so your wire spacing is perfect every time. No more cold spots or wires touching each other.

H. Reynolds

Brilliant 2-in-1 product

Used this in a wet room. Once you seal the joints, it acts as your tanking layer as well as holding the heating. Brilliant 2-in-1 product.

Aquatic Bathrooms

Cuts easily without fraying

Cuts easily with a utility knife to fit around islands and toilets. The fleece doesn't fray.

Tom W.

Fleece grabs adhesive instantly

The fleece on the back grabs the S1 adhesive instantly. I didn't have any issues with the mat curling up at the edges while I was working.

K. Patel

Choose exactly where to put the wire

I love that you can choose exactly where to put the wire. I left the area under the fridge and cabinets empty and just focused the heat where we walk.

Emily B.

Minimal height addition

It doesn't add much height to the floor compared to a screed system. Perfect for my renovation where ceiling height was tight.

BuildRight UK

Allows moisture to escape

Laid this over a new screed that was still curing slightly. The channels allow the moisture to escape without blowing the tiles. Clever design.

Simon T.

Looks high-tech and professional

My customers love seeing this go down. It looks high-tech and professional, and gives them confidence that the heating system is installed safely.

Frequently Asked Questions

The mat is designed to secure electric heating cables up to 4.5mm thickness. This covers the vast majority of standard loose-wire underfloor heating systems on the UK market.

The polypropylene material itself is waterproof. If you seal the joints between the mats with Brit Waterproofing Tape, the entire floor becomes a waterproof tanked surface, ideal for wet rooms.

Yes. Once the heating cable is installed, you fill the studs with tile adhesive (to ensure Load Distribution) and lay your tiles directly on top in the same bed.

Floors (especially concrete and timber) move, expand, and contract. Tiles are rigid. If you stick tiles directly to a moving floor, they crack. This mat separates ("decouples") the two layers, allowing the floor to move independently beneath the mat while the tiles stay safe on top.

You must use a Flexible S1 Tile Adhesive (like BritFlex S1). Apply a 4mm bed to the substrate using a notched trowel, then press the mat fleece side down into the adhesive to ensure a strong mechanical bond.

The mat features rounded square shaped reliefs (studs). You simply press the heating cable into the pre-grooved channels between these studs. No clips, tape, or glue are required—the tension of the mat holds the wire in place.
