Warmlite’s standard hinge gives you smooth operation of the casement sash opening to a wide angle. The friction keeps the sash in position without any additional stays. The concealed hinge design means that when the sash is closed, it is not visible from the inside and is only partly visible from outside.
The restrictor hinge is the same design as the friction hinge but with a built in safety restrictor. This prevents the window from opening more than 15 degrees, until the restrictor is released by pressing a release button on the bottom hinge.
The egress is the easy clean hinge option allowing the timber casement windows to be opened to a 90 degree angle making it easy to clean and usable for escape purposes. In addition it allows the sash, when in the open position, to slide towards the centre of the opening allowing the outside to be accessed for cleaning.
Butt hinges allow for traditional designs to be accurately matched. The hinges can be complimented with a range of ironmongery options with friction stays and multipoint locks, providing the same ease of use as our standard window or a traditional latch if matching the original design is paramount. The hinges can be powder coated to match the paint colour.
Reversible hinges allows the window to be completely rotated so that the outside of the glass is on the inside, for easy cleaning of your timber casement windows.
Hinges can be specified with or without a restrictor. Reversible operation is available on both top and side hung sashes and can be specified alongside fixed and standard opening sashes.
Warmlite use certified Redwood Woodheart® as standard for our timber flush casement windows. We also have a range of hardwoods and Accoya modified timber to choose from.
As standard all our 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 Timber casement windows Options include:
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.
Provides a stable and durable substrate and is supplied as a three ply laminated material for extra stability.
Available in long, clear lengths making it highly suitable for stain finishes where no finger joints are preferred.
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 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 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.
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.
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.
