Vertical sliding sash windows have sashes that move up and down within one complete unit. If that is the opening style you need, share your measurements and preferred appearance. Dolly will confirm the aluminium range, sash details and available hardware before a quotation is finalised.

Enter the structural opening. The quotation tool shows a proposed window size after deducting 10 mm from both overall width and height, while retaining the opening size in your summary. These are quotation dimensions, not approval for manufacture. Ask your surveyor or installer to confirm the final sizes and details.

“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.”
Vertical Sliding Sash Windows: useful questions
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?
A vertical sliding sash is one complete window with vertically moving sashes. Enter the structural opening; the quotation shows the opening and proposed size after a 10 mm deduction in each direction.
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.
