Timber sliding doors offer the traditional feel to any environment it is incorporated in and is the ideal solution for living areas requiring a large amount of sunlight. 

This also enables you to enjoy any panoramic views of the landscape, by affording you the maximum uninterrupted view - simply put that means more glass less frame!  

In our choice of sliding system hardware we have several advantages over our competitors:

  • Grade A rated thermally efficient structure.
  • Easy operation, as the door does not have to be lifted to unlock and/or open. So operating and locking forces are irrespective of the sash weight.
  • By means of the 180o handle position, a safeguarded night ventilation function is enabled that is not visible from outside. The door is completely closed and locked. The bottom gasket components are forced downwards, creating an approx 6mm ventilation gap across the overall width on the top. (This is the only Sliding door system on the market to offer this technology).

Timber External Sliding Doors 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).  

The thermal rating of a window or door is measured in U-Values, the lower the U-Value the better the thermal efficiency it has so will reduce the energy needed to heat your home or premises.

SlidingbiFolds U Values 

Many companies will give you a U-Value based on the centre pane value or the U-Value of the glass. This value will always be lower than the actual value of the window or door system.  

Our engineered timber exterior sliding doors have a U-Value of at least 1.4 or A rated on an energy chart using our standard Low-E double glazed units, this is because timber is one of the most thermally efficient materials used in the glazing industry.

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.

Slidingbifolds has a hardware system for almost any exterior sliding door system.  We can use a range of different hardware systems to allow for top-hung or bottom-rolling that meets the needs of not only residential premises but commercial properties as well.   Most of our external sliding patio doors are bottom rolling allowing for the largest possible lift and slide timber sliding door on the market at a whopping 400kg per door. Incorporating are state of the art hardware with our bespoke timber sections for the doors we are always keen to break new boundaries in maximising the total possible glazed area.  

BESPOKE DOOR DESIGN

Slidingbifolds innovative rolling system provides symmetry to the door design and simplifies the door manufacturing process, we offer the maximum fully glazed systems on the market which can also carry the heaviest weight load per door.

EASE OF OPERATION

Easy operation, as the door does not have to be lifted to unlock and/or open. So operating and locking forces are irrespective of the sash weight.  

SIMPLE ADJUSTMENT

Easy screwdriver access and simple vertical adjustment to either the head of a top hung system or the bogey wheels of a bottom rolling system, allows adjustment of 10 mm making our hardware the most practical system for sliding doors.

SECURE VENTILATION

By means of the 180° handle position, a safeguarded night ventilation function is enabled that is not visible from outside. The door is completely closed and locked. The bottom gasket components are forced downwards, creating an approx. 6 mm ventilation gap across the overall width on the top. (Only Sliding door system in the market to offer this technology).  

INSULATION

Combining our state of the art hardware with recommended exterior weather-seals and double glazed units we can create an insulated external sliding door system.

SECURITY

Slidingbifolds systems incorporate locking screws, secure tracks/guides and non-removable components.  We can also add additional 3 point hook locking systems to our sliding interior doors for any additional security that is required.  Our dropbolts are specifically designed to use with our sliding doors, so that can keep one fixed on a 2 sliding one fixed configuration.  So are substantial, robust and lockable so our sliding door systems can withstand physical attack.
