A: Cork comes primarily from the bark of cork oak trees (Quercus Suberin), mainly grown in Portugal, Spain, Algeria, and Morocco. The harvesting process is sustainable, as trees can be harvested every 9-14 years without being cut down, making it an environmentally friendly choice.

A: Yes. Cork harvesting actually benefits the environment. When bark is stripped, it triggers the tree to absorb more CO2 during regeneration, making cork products carbon negative. Trees can live for over 200 years while being harvested multiple times.

A: Cork spray installations can last 25+ years with proper application. The product comes with a 12-month workmanship warranty and a 10-year product warranty, demonstrating its long-term durability.

Cork spray's effectiveness comes from: • Natural thermal properties that retain heat • Seamless application helping to prevent thermal bridges • Provides a more air-tight coverage, while remaining breathable • Up to 8x more thermal efficiency than traditional renders & plasters

Key benefits include: • Superior thermal and acoustic insulation • Fire resistance (Euro-class B rating) • Moisture control and anti-condensation properties • Natural and eco-friendly composition • Minimal maintenance requirements • Wide range of colour options • Excellent adhesion to various surfaces

The application process involves: 1. Surface preparation 2. Application using specialised spray equipment 3. Multiple coating layers for optimal performance 4. Final protective finish coating

Cork spray can be applied to: • Stone • Existing Render • New Render • Brick & Block • Internal Plaster • Painted Surface • Asbestos Sheets • Stone Walls • Ceramic Tiles • Metal Sheeting • Wooden Panels • Most Building Materials • NOT Silicone

Pricing typically ranges from £65-80 per square meter. While the initial investment may be higher than some alternatives, the long-term energy savings and durability make it cost-effective over time.

Over 30 pre-coloured options are available, plus any RAL colour at additional cost. Options range from natural tones like traffic white, linen and ivory, to modern greys like stone and pewter to bold colours like sage and brick

Cork spray is highly weather-resistant due to its: • Natural water-repellent properties • Breathable composition • Ability to prevent condensation • Durability in various climate conditions
