5 Must have security features for bifold doors


Back in the 90’s, burglars had an easy time of it, entering houses by simply lifting sliding doors from their runners and helping themselves. Manufacturers had to up their game and now thankfully security has become a priority for the design of modern bifold and sliding doors.

Here are 5 security features you should consider when buying a bifolding or sliding door, so as not to put your home at risk.

1. Multi point locks

A multi-point locking system bolts the lead door into the frame and locks at multiple points at the turn of a key, giving a high level of security. This is an absolute MUST for any main door into your house. Single point locks leave the top and bottom of the door vulnerable, a good shove and a single point lock can fail.

2. Concealed in track lock points

Bolts that shoot down in the bottom track and up into the header track will stop the doors from being prized from the frame. Some manufacturers fit these locks to the face of the door, with one at the top and one at the bottom, while other more aesthetically pleasing locks are concealed inside and operated by an elegant single handle in the middle of the door.

3. Anti pick cylinders

The actual cylinder in a lock (the part you insert your key into), can be a weak point. Cheaper cylinders can be drilled out or easily picked. Advances in lock technology mean that anti-pick and anti-drill cylinders are readily available. Many suppliers of doors will offer these as a free upgrade if asked to do so.

4. Toughened glass

The weakest material on the exterior of any building is the glass. It’s now a legal requirement that toughened safety glass must be fitted to all doors. This legal requirement for toughened safety glass also extends to other “critical locations”. Toughened glass is up to 5 times stronger than standard glass.

5. Internal beading

Beads are the long strips of aluminium, timber or UPVC that clamp the glass into place. There was a time when beads were used externally, but intruders soon realised that by popping off the external beads they could easily remove the glass and gain entry. Internal beading eliminates that possibility, as to remove the glass unit the beads must be removed from inside the property.

Thinking about the all-important style, configuration and colour of your new bifold door is of course important. By also making sure you consider the 5 points above, you can rest easy that as well as looking good, your new bifold will keep your family and your home safe.
