External wall insulation

Rendering your property can provide a slight insulation effect but if you are looking to increase the thermal efficiency and reduce heating bills then you need external wall insulation instead. EWI (external wall insulation) is so much better than other options and will help keep your house warm, especially if your house has solid brick or no-fines walls. It also looks great, so contact the specialists today for EWI using silicone render.


We are Johnstone trained and EWI PRO recommended insulation installers with PAS2030 accreditation and TrustMark license and have years of experience, look at our work to see what we can do for you. At D&T Rendering&building Ltd we offer a wide range of other building services such as plaster boarding and plastering, interior and exterior painting, flooring, tiling, extensions and more.

At D&T Rendering&building Ltd we are eco conscious and want to do our part to help the climate. Studies show that insulating your property benefits you and the world we live in. It looks great, last for up to 30 years, and silicone render is the most efficient way to protect the walls of a house! Talk to us to find out more.


Rendering Systems

Render has changed over the years, years ago it was a mix of sand and cement with no longevity or flexibility. These days a polymer-based render is used, such as silicone render, which is flexible, breathable and provides a much better finish. 


An acrylic render can be used, it may be budget friendly, but it picks up dirt and is less durable than silicone render. We offer silicone render as it is more reliable than the traditional mixtures, especially when we combine them with an adhesive base coat and mineral giving it a life expectancy of 15+ years. If you love brick but would like to improve your house's aesthetics, then you may want to look into brick effect render.

External wall insulation worklist

​Most people ask what happens when we install external wall insulation, below is our worklist. 

After we have a thorough conversation with our clients and we sign a contract, we then move on to the next phase:

  1. Scaffolding is erected

  2. First fix – This involves removing any external fittings and preparing surfaces, wooden blocks are used for positioning so everything can go back in the exact same position. Protection films are used on all windows, doors and surrounding areas.

  3. Preparation of the masonry substrate – this involves a building inspection and survey if required to confirm suitability, any identified cracks will be assessed and dealt with.

  4. Boarding and framework – Insulation panels are installed on the framework, depending on the size of the property this can take up to 3 days. They can be wet and dry fixed to the walls, or just dry.

  5. Basecoat and reinforcing mesh cloth – This involves applying an even basecoat and embedding the mesh cloth to reduce any future cracks. Meshed corners and stop beads are installed. Once complete this must cure (dry) before applying the topcoat. Work will continue once dry.

  6. Primer – a layer of appropriate primer is applied and then left to dry.

  7. Silicone render – Your chosen colour of render will be applied and left to dry, this final coat cannot be applied when raining as it risks damaging the finish.

  8. Second Fix – The whole system is sealing with mastic and windowsills are attached and sealed where necessary. All fixtures are refitted, the area is cleaned, and the protective films are removed. Anything on the snag list is dealt with.

  9. Sign off – A report is issued in accordance with the contractual terms.

  10. Finish – The scaffolding is taken down

  11. Pictures are taken and warranties are being issued.
