CTL CERTIFIED to ISO 10545-4 exceeds 40 N/mm2 (20 N/mm2 for CTL-100-142 and the 200mm range). Strong tiles are able to withstand any flexing load making them ideal for floors & steps in wet areas and for high load bearing requirements in public areas.
...and easy cleaning
CTL CERTIFIED porcelain tiles are easy to clean using water or a mild detergent. They will not easily stain or weather so ongoing care after many years is minimal
Many ceramics quickly show crazy cracking.
CTL CERTIFIED to ISO 10545-11 = fully craze resistant. High grade glazing will ensure that the colour and clarity of the tile surface remains intact for the life of your application.
Highly stain resistant
CTL CERTIFIED to ISO 10545-14 = a minimum Class 3 resistance to staining. Tiles are naturally protected from stains and marks and will continually look good in all situations.
Low Water Absorbtion
Water seepage is one of the most common causes of damage over time
CTL CERTIFIED to ISO 10545-3 = less than 1% water absorption (3% - 6% for CTL-100-142 and the 200mm range). This guarantees that tiles will look good for longer and won’t crack in extreme weather conditions. The possibility of damaging seepage, water marks or edge discolouration within the tile is totally eliminated.
Heating and cooling quickly can easily crack most tiles
CTL CERTIFIED to ISO 10545-12 = guaranteed frost resistance. Tiles will not crack in freezing conditions - necessary protection for outdoor use in New Zealand.
Replacing wet area tiles can be expensive
CTL CERTIFIED to exceed En 101 Moh Scale level 5. Tiles will withstand impact ensuring a long life in high use areas.
Constancy of Supply
Many tiles available for decades after supply
CTL CERTIFIED tiles have proven a reliable constant supply over time. These tiles will generally remain available over a long period of time and they are held in sizeable quantities.
Thermal Shock Resistance
Hot sun on cold wet tiles can have a devastating effect
CTL CERTIFIED tiles are designed to resist dynamic temperature change which can quickly cause cracking and discolouration.
Especially important for swimming pools
CTL CERTIFIED to ISO 10545-13 = a minimum Class ‘B’ resistance to acids and alkalis in low concentrations. Class ‘A’ resistance to household and swimming pool cleaners. Salt and chlorine compatible for swimming pool and public use or wet areas around the home
Tried and Tested. End of story.
Top quality CTL CERTIFIED tiles have been used in the swimming pool and bathroom market for more than 30 years. The tiles are rigorously tested before receiving the CTL Certification which means that you can be assured that they will look great and perform well for many years to come.
