Questions

General
How do I request a quote? What information should I provide?

To receive a quick and accurate quotation, please email us at office@polishinterior.com. Include your preferred material (steel, aluminium, timber, etc.), rough dimensions, frame colour, glazing type, key-lock handle preferences, and any site plans or reference photos. If you're looking for a supply and fit service, please let us know.

How should I prepare my site for window and door installation?

Make sure your structural openings are ready — for example, sliding doors require level thresholds. If you’d like sunken tracks, we’ll provide technical drawings with the correct dimensions. Please also confirm site access (especially for HGV/LGV delivery), contact numbers, and any special instructions. If you're unavailable at the scheduled delivery time, let us know as early as possible to reschedule.

What does the process look like from enquiry to delivery?

Once you send us your project details, we’ll prepare a tailored quotation. If accepted, we move into the technical phase — providing detailed drawings, confirming finishes, and checking all final dimensions. Every element is then crafted in our Kraków workshop. We’ll coordinate delivery (and installation, if agreed), keeping you informed throughout. You’ll have a dedicated point of contact from start to finish.

Do you supply only, or can you also install?

We primarily offer supply-only, but in some regions we can provide a supply-and-fit service depending on the scope and location of the project. Let us know your needs and we’ll advise accordingly.

Can I visit your workshop or showroom?

Yes — you’re welcome to visit our workshop in Kraków by appointment. It’s a great opportunity to see how our products are made and explore material and finish options firsthand.

Do you work with both residential and commercial clients?

Yes. We manufacture for private homes, listed buildings, multi-unit developments, hospitality spaces, and commercial projects. Each product is tailored to the project’s technical and aesthetic requirements.

What locations do you deliver to?

We regularly supply across the UK and mainland Europe. For more remote or restricted-access sites, we’ll help plan the most efficient delivery method.

Product
Do you offer different materials for windows and doors?

Yes — we work in hot-rolled steel, stainless steel, aluminium, timber, and even copper finishes. All our products are bespoke and tailored to your project’s requirements.

Are hidden tracks available for sliding doors?

Yes, we offer hidden track options. Pricing depends on the number of tracks, leaves, and overall door dimensions. Contact us with your requirements and we’ll provide a tailored quote.

Do you offer fire-rated windows or doors?

Yes, fire-rated options are available — including steel doors rated for 30-minute fire integrity. Let us know your specific compliance requirements when requesting a quote.

Can you make curved or arched windows?

We manufacture radius (curved) windows as well as arched window types. Radius windows require bent profiles and curved glazing and are generally more expensive than standard ones. The final cost will depend on your chosen system (steel, timber, aluminium, etc.). We're happy to recommend the most suitable and economical option for your project.

What acoustic performance can you provide?

We offer acoustic glazing up to 51 dB in both double and triple glazed formats.

Do you offer integral blinds within glazing?

Yes — we offer venetian, pleated, and roller blinds sealed between glass panes. Mechanisms include manual (cord, knob, magnetic slider) and motorised options — even app-controlled. Lamella sizes vary depending on the unit but typically include 20mm, 22mm, 27mm, 29mm, and 32mm.

Do integral blinds affect the window’s U-value?

Integral blinds are typically considered decorative (like Georgian bars), so they aren't factored into U-value testing. However, they can improve thermal performance by reducing solar gain or heat loss depending on their position.

Can I use hidden handles in the UK given insurance requirements?

It depends on your insurance provider. Some insurers accept hidden handles (AXA, for instance), while others require key-lockable handles. We can advise or adapt the hardware to meet your policy's needs.

What’s better for privacy — mirror glass or venetian blinds?

Mirror glass provides permanent reflectivity during daylight but offers less privacy at night when interior lights are on. Venetian blinds offer adjustable privacy. We also offer PrivaLite glazing — switchable glass that toggles between clear and frosted using a remote.

What happens if my site measurements change from the architectural plans?

It’s quite common for on-site dimensions to vary slightly from plans. We always recommend confirming final structural openings before manufacture. If dimensions change, we can adapt the design or re-quote if necessary.

Do your quotes expire?

Yes — quotes are valid for a limited time due to fluctuating material and production costs. If significant time has passed since your quote, we may need to update it before proceeding.

What if I’m not available at the time of delivery?

Let us know as early as possible and we’ll reschedule your delivery. Clear communication around timing, access, and site conditions helps us deliver as smoothly as possible.
