Wooden Bi-folding Patio Doors (Open In)

Our traditional inward opening bi-folding patio door has been developed for high performance and long life.

It can be configured to suit a wide range of sizes, designs and layout options and there are a wide range of glazing, timber and paint options available, all offering our market leading guarantees.

Our traditional wooden patio doors provide:

A premium product manufactured from the finest materials and retaining traditional period features.
Engineered timber providing excellent durability, all from certified, sustainable sources.
Market leading warranties with a 10 year paint guarantee as standard.
Excellent weather performance with third party test validation.
High quality hardware and design features providing enhanced security.

Low Resistance Sliders - The use of the best hardware systems available ensures that our doors have the best method of operation, the latest innovations and highest quality parts. The clearest way these can be experienced is in the operation of the door, which slides effortlessly on its rollers along the track with minimal input. This will last for the life of the doorset with only minimal maintenance. Multipoint Locking - The multipoint locking system provides locking points around the door operated by the handle. In addition to excellent security performance, these fixing points prevent the timber from moving contributing to the long life of the door. Adjustable Hinges - The nature of timber means that there will be some movement of the doors over time. Adjustable hinges allow for any movement in the doors to be simply adjusted to ensure that the doors can provide the same smooth feel as the day they were installed. Weather Sealing - The use of draught seals on the door leaves and within the track ensure that all parts of the doorset are well sealed, providing excellent protection from the elements. Internally Beaded - In common with all of our products the doors are glazed from the inside providing enhanced security and improved weather performance, which as a result gives longer life to the paint finish and glazing unit.

Both inward and outward opening bi-folding patio doors have the same range of possible configurations allowing the doorsets to be configured to suit the size of the opening and the layout of the room.

The diagrams below show a wide range of possibilities but almost any configuration is possible, so if you require anything different it will more than likely be possible.

Our bi-folding patio doors are manufactured from engineered certified Redwood Woodheart® as standard. We also have a range of hardwoods and Accoya modified timber to choose from.

Redwood WoodHeart®

As standard all frames and window sashes are manufactured from Redwood WoodHeart®, the heartwood taken from Nordic Scots pine trees (see diagram). By utilising this heartwood, we get very good durability and dimensional stability, as well as very good thermal performance.

The reduced moisture uptake and increased stability of the timber produces a substrate which enhances the coating life span (this is key to a long life window because if the coating remains intact the window will last indefinitely).

In addition it is engineered to be knot free, which along with the aesthetic effect, also prevents resin exudation, which will damage the coating.

The cill on sliding sash windows and the cill extensions on all products (if required) are, due to increased exposure to weathering (both water and UV light), manufactured from FSC sourced hardwood.

Other Options

It is possible to supply our products complete in Redwood WoodHeart® (usually only if a transparent finish is required) and in addition the following four timber options.

Red Grandis

Red Grandis

Red Grandis provides a stable and durable substrate and is supplied as a three ply laminated material for extra stability. It is available in long, clear lengths making it highly suitable for stain finishes where no finger joints are preferred.

European Oak

In the past, high quality windows have been made from European Oak due to its durability. However, it has a tendency to move which can cause failure of the coating system and the insulating glass units. To overcome these problems we use knot free laminated European Oak which has FSC Chain of Custody.

Accoya Accoya

Accoya is an exceptionally stable modified timber and has the highest durability rating. It provides the ultimate substrate for our coating system allowing us to give a coatings warranty of up to 12 years. Accoya also comes with FSC Chain of Custody.

Sapele Sapele

Sapele is a very stable and durable tropical hardwood that is very well suited to joinery manufacture. It’s dark and dense characteristics make it a very attractive timber, well suited to a transparent coating. We source this with FSC certification to ensure it is from sustainable, certified sources.

10 Year Paint Guarantee - No Redecoration Required Our advanced coating system has been developed to provide maximum protection to the timber, whilst allowing it to breathe and let its natural characteristics show through.

This allows us to give a 10 year guarantee on paint finish (a 25 year guarantee may also be available – please contact us for more information).

The coating system is vitally important for the longevity of timber windows and doors. It essentially serves three purposes; to prevent UV and visible light damage to the timber surface, to slow down the rate at which moisture is absorbed and released from the timber and to provide an attractive colouring and surface finish to the product.

Opaque Paint

We can provide almost any opaque colour, all we require is a RAL Standard, RAL Design, Natural Colour System (NCS) or British Standard (BS 4800) colour or an actual sample. View our Coating System Guarantee brochure.

Translucent Paint

We can provide almost any translucent colour, all we require is a RAL Standard, RAL Design, Natural Colour System (NCS) or British Standard (BS 4800) colour or an actual sample. View our Coating System Guarantee brochure.

Translucent Paint Samples

Dual Colour

We can provide dual colour windows and doors with a different colour inside to out or frame to sash. This also allows for the frame and sash to have a different dual colour specification if required.
