Timber French Door Systems in Detail

U-values and saving energy

In the average home, 80% of the energy used is for heating, but much of this heat just disappears through poorly insulated roofs, walls, windows and doors.

One of the most important considerations when it comes to a choosing door system for your home should be the U-value rating, energy efficiency is an important issue, so much so that it has now been addressed in legislation..
The latest revisions to building regulations (ROI & UK) mean energy efficient doors will be made mandatory. All new doors will need to have a U- value of 1.8W/m2K or less (the current standard for energy efficient windows).

SlidingbiFolds U Values 

What exactly is the U-value?

 The U-value or “overall heat transfer coefficient” shows how well a building product conducts heat. In other words, the U-value represents the rate of heat transfer through a building element, such as a wall, floor or window, over a given area and under agreed standard conditions.

The lower the U-value is, the slower the rate of heat flowing through the object and therefore less heat will escape through the door– or put differently the lower the U value the lower the potential costs of heating that particular building.

Slidingbifold’s products not only meet the new stringent changes in Building Regulations 2010 (UK) 2011 (ROI) ... we already surpass further changes planned for 2013.

Our French doors can be manufactured to open outwards or inwards depending on your requirements. The sizes and configurations shown below are our recommendations but if you have a specific requirement that is not shown please contact us.

The following designs are the recommended number of panels for aperture width but other configurations may be available if required.

Min Height = 1800mm Max Height = 3000mm Max Leaf Weight = 80kg

All configurations show outward opening doors but inward opening configurations are also available.

2 Door Configuration Min - max width 1000mm – 2000mm
3 Door Configuration Min - max width 1500mm – 3000mm
4 Door Configuration Min - max width 2000mm – 4000mm
6 Door Configuration Min - max width 3000mm – 6000mm

Your new timber French door set is supplied fully factory finished in your choice of translucent stain finish or specified RAL colour, this is important to maintain the integrity of the product. Many suppliers offer an unfinished product which means you are responsible for applying at least three coats of wood stain or paint which can be very time consuming and could compromise the warranty if not applied correctly.

Standard Spray Finishes

Our French doors are factory sprayed with three coats of 250 microns per coat which provides a finish comparable with up to 15 coats of brush applied paint. Factory finished doors are low maintenance and have a very long life span of up to 10 years before they require attention.

Translucent Stain Finishes

Choose from a translucent wood stain from the Sayerlack Hydroplus wood finishing range which provides a high quality finish whilst protecting the timber against the weather. We have a sample range that we can post to you before confirming your order.

RAL Paint Colours

Alternatively, you can also choose from over 200 different RAL colours available in matt or satin finish. You can download a RAL colour chart here for guidance purposes but we recommend you obtain a printed RAL colour chart to confirm your colour choice at the time of order. A few RAL colours may require an additional set-up fee, please check with us prior to ordering

Each of our French doors will be constructed from our exclusive engineered timber to prevent warping and twisting. There is a choice of timbers available as standard these are Birch, Mahogany, Iroko and Oak. Other Hardwoods are available on request.

The frame will be made of the appropriate hardwood to match the Door construction. All Frames are also constructed using our engineered timber.

We use PLANITHERM

PLANITHERM is Europe's best selling range of high performance low-emissivity glass (low-E glass). The glass utilises the very latest advancements in thermally insulating glass coating technology.

Specially manufactured by Saint-Gobain Glass for the UK market, PLANITHERM products are specifically designed to keep interiors more comfortable in the winter months and improve your home's energy efficiency.

The thermal insulation provided by low-E double glazing is three times more efficient than that of standard double glazing and PLANITHERM products are the ideal low-e solution to meeting and exceeding the newly revised Building Regulations energy efficiency requirements.

SlidingbiFolds Planitherm Glass 

PLANITHERM products use a special coating to reflect heat from domestic heat sources back into the room, rather than allowing it to escape through the windows. At the same time, this coating allows free heat and light from the sun to pass through the glass, warming the room and further contributing to the energy efficiency of the windows and helping to reduce your energy bills.

Additional Options

The PLANITHERM range can be combined with many other Saint-Gobain Glass products, providing a multitude of high performance, multi-functional glazing options, including:

 • Self-cleaning and/or solar control glazing
 • Acoustic insulation
 • Obscured and/or decorative glazing

This combination of excellent thermal insulation with high solar heat gain makes PLANITHERM the most energy efficient window glass available and the best possible choice for energy savings
