Aluminium Casement Windows
An aluminium casement opens on hinges, making it a familiar choice for many rooms. Mix opening and fixed sections to suit your view and ventilation needs. Unlike tilt-and-turn, the casement options here open outwards; Dolly checks the proposed arrangement and specification before quoting.
Supplier product imagery. Example colours and configurations are confirmed in your quotation.
Make it yours, one step at a time.
Start with the overall width and height, then request up to four panels with the opening preferences you need. Fixed glazing and dummy sash are different choices. The confirmed overall quotation width limit is 3000 mm; larger requests are retained for manual review. Add colours, glazing and hardware preferences without needing a final manufacturing specification.
Before you start
Have the approximate width and height ready. That’s the only product information you need to begin; we’ll guide you through the rest with simple questions.
Price confirmed after review. Nationwide supply-only; installation is arranged separately.
“Dolly’s were brilliant. I needed a fair bit of help getting the order sorted and they talked me through everything. I’d have struggled without them, to be honest. The windows and doors are exactly what I wanted. Really happy.”

What do I need to start a quote?
Have your approximate overall width and height ready, in millimetres. You will enter your contact details first, then choose the product preferences. Dolly checks the complete specification before quoting.
How are openings and fanlights shown?
Each main panel has its own opening preference and optional fanlight within that panel. Fanlights never span neighbouring window panels. All positions are viewed from outside.
Does this quote include installation?
No. Dolly’s Windows supplies nationwide; surveying and fitting are arranged separately with your own installer. Adding to the basket does not place an order or take payment.
