What Makes Our Dublin Casement Windows Energy Efficient?

Every casement window we install uses 28mm argon-filled double glazing as standard (A-rated), with 42mm triple glazing available for north-facing rooms or coastal locations. Our multi-chambered uPVC frames trap insulating air, while Low-E glass coating reduces heat loss by up to 40% compared to older single-glazed windows.

Why this matters for Dublin homes:

Triple glazing eliminates condensation in poorly-heated bedrooms and cuts heating costs by an average of €300-€450 annually. All units exceed Irish Building Regulations Part L and are certified A-rated by NSAI.

Available in white uPVC (from €600 + VAT installed), anthracite grey (most popular in Dublin 4, 6, 8), and rosewood finishes.
