Amazing price for Windows

Just had my new windows installed through Winplex and couldn’t be any happier! From getting the quote to instalment the service has been amazing! Amazing price compared to other quotes I had received and well in our price range. Constant check ins and following up was on point. Our new windows and doors look phenomenal and I’m over the moon! Highly recommend Winplex to anybody who is looking at getting double glazed Windows.

Loving my new windows

I’m loving my new Winplex windows. I got them installed just in time for that super hot day yesterday – even though it was 44 degrees outside, I barely used my A/C all day! They look great, and the built in fly screens mean that I can have the doors and windows open without letting in any insects. The Winplex team kept in contact from ordering, through installation and then followed up with me afterwards. I couldn’t be happier.

Bifold Doors vs Hinged Doors

Bifold Doors
Hinged Doors

Hinged doors can take up space due to the fact that they swing inwards or outwards to open. That means you need to provide clearance, which may not be an option if you have small living or office space.

Hinged doors, as well as Tilt and Turn doors, can also get loose over time, making them swing shut or open with just a slight gust of wind or if they’re not leveled. You don’t have to worry about that with a Bifold Door.

Bifold Doors vs Sliding Doors

Sliding Doors

Sliding doors typically open up on one side while the other is either fixed into position or won’t provide much opening since they will overlap with the other glass panel. Sliding doors are also prone to getting dirt on their sliding mechanism.

Likewise, the grease could dry out over time which will make them harder to slide open/close. Bifold’s simple yet clever design allows it to open and close like an accordion.
