Timber Subframes

Some projects will require a timber subframe to sit between the masonry and our bronze casements, either for the look you are trying to achieve or because of fixing limitations.

Timber surrounds for our bronze windows and doors are made in our extensive wood machine and assembly workshops at our sister company, Vale Garden Houses where we have all the latest CNC equipment. All framework is constructed using a traditional method - assembled with mortice and tenon joints and secured with concealed stainless steel or brass screws. The framework is enhanced with decorative mouldings as chosen from our range of standard profiles.

Full working drawings are produced for approval prior to manufacture of all frames.

Timber Profiles

Frames can be made in a variety of timbers depending on the finish required and we have eight standard profiles available to suit the period and style of your project. Each are adaptable to accept single to multiple casements, and with horizontal transoms for clerestory panels.

All our timber profiles will accept the Thermabronze, Heritage and Advanced system windows. The most popular are the Belton, Old Mill and Hardwick as these are also best suited for making timber doors which will accept bronze inserts to complement our opening casements.

We can, if the project requires it, provide sill extensions, scribe strips, timber trims and window boards.

Timber Choices

Douglas fir and Sapele would normally be chosen if you are looking for a painted frame for your windows, and we would generally specify the timber depending on the colour you are selecting – Douglas fir for lighter colours and Sapele for darker colours. There are 42 colours available through our Period Paint Collection, however we also have four colours which have been designed specifically to compliment our bronze windows and doors.

Oak is a popular choice of material for timber subframes, given its appealing look and durability. However, it's important you take into account the style, size and location of the oak frame in conjunction with exposure to environmental conditions within your decision making process. This is because there is an expectation of movement with twisting and shakes occurring which are typical of this timber and in line with industry standards.
