A flush door design can be categorised by the sash fitting flush within the frame, therefore, removing any protrusions.

The flush design is inspired by traditional timber joinery, imitating and replicating classic manufacturing techniques to allow a look that reflects the design of a timber door.

This means that you can install a look that is not only eye catching but also practical. A flush door will complement your property while not compromising on its heritage status.

The sash aspect typically refers to the double glazed window aspect of your heritage flush door.

Through modern day advancements, our flush doors are able to improve your home to the current standards of thermal efficiency, security, durability, design and performance.

This leaves you with peace of mind knowing that you are investing in a product that not only leaves your home looking beautiful while also improving your home’s practicality.

Intelligent Design

Having a timeless appeal to all, our flush sash doors can be custom made for any home. Whether you live in a modern home, traditional or period property or your home is a new build - we can match your new door to your home for the perfect fit. Whatever your individual style may be, we have a wide range of colours, finishes and hardware options for you to choose from so that your bespoke flush sash door will add a personal touch to your home.

With these weather resistant qualities, you are left with peace of mind knowing that your new door will not allow water damage. It will also save you money on your energy bills because of the thermal efficiency that comes with weather resistant flush sash doors.

Lasting Quality

It is common knowledge that traditional timber doors have a lot of problems over their life span. This can compromise on not only the look of your flush sash door but also energy efficient qualities and your home security. Without worrying about the common issues of your flush sash door warping, cracking, discolouring, rotting or bowing, our heritage doors capture the appeal of a traditional timber door. What you are left with is the great performance of a trouble-free door that has a better life span and amazing energy saving techniques.
