Our work on heritage properties
We understand that by the time you approach a manufacturer, much of the work has already been done. You’ve likely met the homeowner, surveyed the property, agreed the design, taken measurements, and finalised the specification. All that is left to do is get an accurate quotation and the assurance that the finished products will arrive exactly as ordered.
This is exactly how we work. Start by providing us with your design specifications, dimensions, glazing requirements, glazing bar layouts, finishes and any other project details. In return, we’ll prepare a clear, competitive quotation before manufacturing your bespoke products to those exact requirements.
Products you can install with confidence
Our timber windows and doors are designed to complement everything from conservation properties to contemporary homes, offering excellent thermal efficiency, security, and durability without compromising on aesthetics.
Every Nine Zero product is manufactured with precision using carefully selected FSC-certified timber, and, depending on the product specified, our windows and doors can also be manufactured to meet recognised industry standards and certifications, including:
- PAS 24 security standards
- Secured by Design
Combined with comprehensive guarantees on timber, glazing, paint finishes and workmanship, you can install every product with confidence.
Technical expertise to support your project
Our team ensures complete compliance with all regulations affecting timber windows and doors, including:
- Part L – Energy efficiency
- Part K – Safety glazing
- Part Q – Security for new dwellings
- Part F – Ventilation requirements, including trickle vents
Whether you need advice on glazing specifications, ventilation requirements or selecting the appropriate product for a particular property, we’re here to help.
Rather than simply manufacturing what we’re given, we work with you to ensure specifications are practical, compliant, and suitable for your project. This helps reduce the likelihood of costly mistakes or callbacks after installation.
