Choosing your products
Casement or tilt-and-turn windows?
Compare how each window opens and the space it needs around it.
A familiar outward opening
The casement choices on this website open outwards on hinges. Depending on the confirmed layout, a window can combine opening sections with fixed glazing. Start with where you want ventilation and which parts of the view you would like to keep clear.
Two operations in one sash
A tilt-and-turn sash tilts inward for ventilation or turns inward for a wider opening. That is one opening sash with two modes, not two separate windows. It needs suitable space inside the room when turned open.
Check the position of blinds, curtains, taps, furniture and anything placed on the sill. The website describes hinge direction from outside looking in, so take a moment to picture that viewpoint.
Do not decide from a photograph alone
A closed-window photograph may not show its opening mechanism. Use the product description and opening choices alongside the image. Handle and hinge compatibility depend on the exact system. Safety, ventilation and any escape requirements need a project-specific check rather than an assumption based on the style name.
Tell Dolly what matters
Bring approximate dimensions and a short explanation of the room and access needs. Dolly can check the available arrangement and hardware before quoting. The tilt-and-turn journey does not offer fanlights; do not carry a casement layout into it by assumption.
