Why Prices Change

Price adjustments are driven by factors outside of our control, including:

  • Raw material cost volatility
    Prices for primary materials such as cement, steel, resin and insulation fibres can shift rapidly due to global demand

  • Energy and transport costs
    Fluctuations in fuel, freight and logistics costs can significantly impact manufacturing and delivery
    Supply chain constraints
    Lead times and scarcity in key components can increase cost bases for production

  • Industry-wide inflation
    Broader economic inflation affects labour, production overheads and administrative services

While we work hard to absorb costs where possible, occasionally a price adjustment is necessary to ensure ongoing supply, service performance and compliance.
