Sky K Rend Silicone TC 15 is an organic resin render incorporating a silicone resin emulsion and an acrylic resin dispersion in a ready to use render.

If applied according to the manufacturer’s instructions it can be used on a variety of prepared exterior surfaces to provide an attractive, low maintenance textured finish.

K Rend Silicone TC incorporates the benefits of silicone technology to provide a water repellent final surface which gives excellent protection.

The silicone allows water vapour to pass freely through the render whilst allowing the finish to remain weather resistant.

K Rend Silicone TC contains a biocide to help prevent infection from moulds, yeasts and algae and it has a low susceptibility to soiling and contamination.

K Rend Silicone TC is a low odour, ready to use organic resin render which is quick and easy to apply and is available in a wide range of colours.

It provides excellent adhesion and application properties and, following appropriate preparation, can be applied to a wide variety of substrates.

Although primarily for external application, K Rend Silicone TC can be used internally.

No matter whether you choose a local installer or a national company, there’s a few tips to help you find the right installer for your home insulation improvements, such as asking for recommendations and making sure that they’re part of a certification scheme. This makes sure that they have the right skills and standards of workmanship to carry out the installation, and you can be sure that they know exactly what they are doing.


1. Thermal inspection picture in portfolio

It’s worth seeing a installer’s previous work. There’s no harm asking if you can see any properties nearby that they’ve installed insulation in. Best way would be to see Infrared Thermal Imaging Inspections. Thermal cameras spot small, but key changes in temperature in different areas of a house, identifying problematic areas that the human eye never could and some that a visual inspection could only hypothesize.

2. Reviews

Along with checking recommendations and previous work, finding reviews online can often be a great way to find out if they provide a good service or not. However, it’s best not to solely rely on reviews you may find or review websites, as there’s no controlling who writes them.

3. Compare prices

Comparing prices will also ensure companies can’t take advantage of you and give you a fair price. 

4. Word of Mouth

The best way to find a great insulation installer is through recommendations. Make sure you ask friends and family. They will most likely give you their honest opinion and can tell you from first hand experience.


Whether you require a wall, cladding, external wall, loft or floor insulation fitted, you can find and hire your local insulation installers from popular UK web pages. A simple internet search will return thousands of potential installers near your area.
