Frequently asked questions
FAQ: the questions homeowners and architects ask us most often, with our answers. Can’t find yours? Write to us.
Our workshop and materials
Where is your workshop and where do you work?
Our workshop is in Casole d’Elsa (SI), at Località Il Piano 71, in the Sienese Valdelsa. We work throughout Tuscany, particularly in the provinces of Siena and Florence, and handle projects in Europe, the Middle East and the Americas.
Do you only make made-to-measure doors and windows?
Exactly: every door and window is designed and built for the building it will go into: size, timber, profile, finish and hardware are decided together with you or your architect.
Which timbers do you use?
For windows: European oak, Alpine larch, Douglas fir, iroko and teak. For interior doors also Italian and American walnut, cherry, ash, elm and chestnut. For portals mainly oak, larch, chestnut and teak. All timber is FSC or PEFC certified; other species are available on request.
Performance and historic buildings
Can windows be replaced in a listed building?
Certainly. We make windows and doors that faithfully replicate original profiles and geometries and prepare the technical documentation for the Heritage Authority. However, where possible we restore the original instead of replacing it.
Do wooden windows insulate as well as modern ones?
They do. In fact, with low-emissivity triple glazing our windows reach a Uw value of 0.68 W/m²K, suitable for Class A+ and NZEB buildings. In addition, a wood-aluminium version is available for extra protection outdoors.
Do you make wooden security doors?
Yes: entrance doors with an RC3 or RC4 certified armoured core, clad in hand-worked solid wood. From the outside they look like a traditional wooden door.
Design, finishes and quotes
Do you work to the architect’s drawings?
Happily: we supply DWG files and technical data sheets, build prototypes before production and can have handles and hinges cast to your design.
Which finishes can I choose?
Matt or gloss paint in any RAL or NCS colour, open-pore lacquer, natural oil, wax, pickled (decapé) effect and vintage finish.
How do I request a quote?
Fill in the form on the Contact page, call +39 0577 925045 or email info@cerriserramenti.it. Tell us where the building is, which doors and windows you need and, if you have them, any drawings or photos: we will get back to you to arrange a meeting.
How long does it take to make doors and windows?
First of all, it depends on the number of pieces, the timber and the work involved: every piece is built from scratch. We will give you the lead time together with the quote.
Have a project in mind?
Tell us what you have in mind: location, type of door or window, timing. The Cerri family answers you directly, not a call centre.
