FAKRO Roof Windows

Yes, they are ideal for this. Because opening both sashes completely eliminates the central pillar, French casement windows create a much larger clear opening than standard windows. This makes them the perfect choice for tighter bedroom openings where a standard window frame would block a legal emergency exit route.

Absolutely. Even without a fixed central post, security is not compromised. Built on the 70mm Profile 22 system, our frames feature heavy-duty multi-point locking mechanisms and reinforced internal sections that securely lock the two sashes together. The entire system achieves strict PAS24 Enhanced Security and Secured by Design status right out of the box.

Our French casements are incredibly versatile and can accommodate a wide range of glazing thicknesses. You can choose standard 24mm or 28mm double glazing to easily achieve a 1.2 W/m²K U-value (WER A+). For ultimate insulation, the frames can also take 36mm, 40mm, and 44mm triple glazing, dropping the U-value down to an ultra-efficient 0.8 W/m²K (WER A++)

Because every single French casement window is custom-manufactured to your exact specifications, lead times can vary depending on the chosen profile colour and current factory capacity. Standard white frames typically have our fastest turnaround, while special woodgrain foils or dual-colour options can take slightly longer. Contact your local EWE branch and our team will provide an the current lead time for your requirements.

The system features a standard 70mm frame depth. This makes it an ideal direct replacement for older timber or first-generation uPVC windows, fitting neatly into standard UK brickwork reveals with minimal disruption to internal plaster lines.

We accept either. Trade installers should provide tight manufacturing sizes. For DIY homeowners, our branch teams can offer general guidance on standard deductions for tolerances and cills, but we don’t carry out site surveys, so we can’t confirm your actual structural dimensions. Your quote will clearly itemise all measurements, window styles, and opening directions. Please check this carefully before signing off — all items are custom-manufactured to these exact specifications and cannot be refunded or altered once production has started.rnrnResponsibility for measurement accuracy rests with the customer.
