Why EWI RenderStore Is Trusted — Not Part of the 98% Insulation Scandal
No. EWI RenderStore is completely independent from the ECO scheme and its contractors. We supply and support certified systems and work only with trained professionals who follow BBA-approved methods and manufacturer specifications.
We supply only genuine, certified external wall insulation systems backed by:
- BBA certification
- Manufacturer warranties
- 🛠Installation guidance based on PAS2035 standards
Our products are designed for long-term performance, moisture control, and thermal efficiency — not quick fixes.
We actively educate and support installers to avoid all common failures:
- No live wires left exposed — electrical safety is non-negotiable.
- Boiler flues are extended properly by certified plumbers to meet gas safety regulations.
- Ventilation is preserved — we never block air bricks or cover vents.
- Window cills and finishing beads are installed with precision to prevent water ingress.
- No polyurethane foams or dodgy fillers — only approved insulation boards and adhesives are used.
Yes. We encourage installers to conduct site-specific assessments before any insulation work begins. This includes:
- Substrate condition checks
- Moisture level testing
- Thermal bridging analysis
- Compatibility with existing building fabric
This ensures the system is tailored to the property — not a one-size-fits-all shortcut.
Absolutely. All systems we supply meet:
- Fire safety standards for external wall systems
- Approved Document B compliance
- Tested fire classifications (e.g., Euroclass ratings)
We never supply untested or uncertified materials.
Yes. We offer:
- Post-installation checklists
- Photo documentation guidance
- Manufacturer-backed warranties when systems are installed correctly
This gives homeowners peace of mind and protects installers from liability.
We’re not just a supplier — we’re a partner:
- Training courses on EWI, render systems, and detailing
- Technical support line for on-site queries
- Access to datasheets, CAD details, and installation guides
We help professionals do the job right — every time.
We promote systems that are:
- Environmentally responsible — low VOC, recyclable components
- Durable and low-maintenance — designed to last decades
- Thermally efficient — reducing energy bills and carbon footprint
We believe insulation should be a long-term investment, not a short-term fix.
