Board and Tiles

Purchased everything I needed from tile mountain, including the insulation board, tiles, adhesive, grout, silicone, etc.. All arrived one the promised date, not a singe damaged item. Quality of products was great. I've uploaded a picture (we are nearly finished).... Would recommend.

Incredibly easy to install!

Not too much to say about these - all went in very easily and levelled up nicely. I grouted them to the floor, rather than fastened with washers, but this was easy enough. Also very easy to cut to size. Would certainly buy/use again.

Are these suitable for on a wall


Our advice: Yes, this item is suitable for walls.

Would these be suitable to use with Vinyle Click flooring? Life Glacier White Marble Tile Luxury Rigid Core Click Vinyl Flooring


Our advice: Yes, you could use these together. It would still be necessary to use a Vinyl Underlay as well.

Garrison Pc 06/02/22

Hi. I have Livyn Ambient Click Quick Step Vinyl flooring boards that I want to put directly on top of Nassboards Red Box underfloor heat mat kit, without adhesive or floor levelling compound. Are your boards suitable for my project?


Our advice: No, the insulation boards would not be suitable for this. The underfloor heating would need encapsulating in a leveling compound giving at least 13mm between the heating and the flooring.

Do you offer NHS discount


Our advice: Yes, we do please email us a photo of either your Blue Light card or NHS ID.

Heather M. 11/04/21

what is needed to cut these boards?


Our advice: To cut these boards we would recommend using a score and snap knife (SKU 445700).

Allan 09/04/21

what screws/fixings would you use with this to fix to a plywood floor


Our advice: These can be secured to the floor using normal screws, and you can also use a small amount of adhesive if you wish.

Rick 15/01/21

Hi, Can you just screw these down to the floor boards or do you have to use adhesive aswell?


Our advice: You would apply these tiles using the Keraquick White Fast Setting Adhesive 20kg, or if you’re doing a DIY project, we would recommend the slow setting version of this.
