At Pranger Kozijnen we choose our own factory, take our own measurements and install with our own people. No dealers, no subcontractors. The same team you call for a quote will be there for the survey and will fit your windows.

We are part of Pranger Bouw, a family business in construction since 2011. Since 2023 we have brought that approach to uPVC windows, sliding doors and entrance doors: across Gelderland.

FREQUENTLY ASKED QUESTIONS

Asked often.
Answered clearly.

The questions we get most often. Yours not among them?

Ask your question directly
01What is the difference between HR / HR+ / HR++ glazing?
HR, HR+ and HR++ indicate the insulation value of the glazing, the higher, the better the heat stays inside. As standard we fit HR++ glazing: the best insulation, lower heating bills and ISDE subsidy.
02How long does a full window replacement take?
For an average home, allow one installation day per floor. You'll get the exact lead time with the quote.
03Can I get ISDE subsidy on new windows?
Yes, as an owner-occupier with insulating glazing. You submit the application to RVO yourself (with DigiD); we prepare everything and guide you.
04What is the lead time?
Allow six to ten weeks between approval and installation. You'll get the exact timing with the quote.
05What warranty do I get?
A 10-year warranty on installation and up to 30 years on the profile. We explain exactly what it covers.
