PVCu Installation

Be Prepared

Be prepared for another Wellington winter by improving your home before those chilly winds blast through! 

Recently, window manufacturers have created new PVCu windows, that are very aesthetically pleasing, whilst keeping the benefits that PVCu windows are well known for, such as cost-effectiveness, durability, and security making them a great choice when replacing windows.

Not only will choosing PVCu save money on the cost of the window, they will help you to cut down on household bills too, as they are very energy efficient. They are fantastic insulators, so they keep all the warm air inside and let no drafts into your property. Also, they are not conductive, meaning they do not pass on heat, which reduces the fluctuation in temperature inside your property, therefore reducing heating and energy costs.

Unlike timber, PVCu windows are extremely durable and do not rot or warp so will last for years. Meaning no need to replace them unlike other options and therefore, saving money in the long run.

As a property owner you should always be cautious when it comes to security. PVCu windows will give you peace of mind when it comes to keeping your property secure. Their frames are very sturdy making them extremely difficult to damage or break through.

Do you enjoy a lie in on a Sunday morning? Don’t let your neighbours disturb you by using PVCu windows, they are able to cut down heaps of external noise.

Apart from a wipe with a cloth and some soapy water to clean it every now and again, PVCu requires practically no upkeep at all. Compared to wooden window frames which need to be treated and re-painted regularly, making it a more convenient and time-saving option.

If you’re thinking of installing PVCu windows in your property, get in touch with us and we'll be happy to help!

Benefits of PVCu

Condensation is a common problem in single-glazed Kiwi homes. Moisture from condensation can cause unhealthy mould around windows/doors, and damage your health and your home.

New Install

PVCu & Aluminium Insert Windows & Doors Installation

Installation consists of removing the transom, mullion and sash sections, making good and retaining the surrounding frame.

PVCu or aluminium inserts are made to your configuration and installed, all of which is carried out on site.

Providing your existing windows are in good condition this can be an ideal solution. The process for all retro­fitted double glazing is to remove your existing single glazing and replace it with new double glazed units together with colour matched external beading. Closing sashes generally cannot be retro fitted so replacements will be needed. New handles are standard and extra security hardware can be fitted as required.

Timber Windows and Doors

As with PVCu and aluminium, if your frames (even double hung) are in good order they can be modified to accept double glazing. If not, replacements can be supplied.

This process consists of the removal of your windows, de­glazing them and machining them to accept the new doubled glazed units. The frames are then sanded down and pre-primed ready for reglazing. The glass units are then sealed into the frames with paintable silicone and new external timber beads ready for a top coat of paint.

Flexible draught stripping is fitted to all opening sashes on installation. This is the ideal time to consider any alterations to the configuration of your windows eg. removal of some sashes for a larger unit to achieve that panoramic view and also for updating security fittings.

Glass Units

20mm units consist of a 4mm glass pane, a 12mm spacer and another 4mm glass pane. This can achieve a 50% heat loss reduction and a 25% noise reduction. These reductions can be increased by the addition of argon gas to the glass spacing.

N.B. The glass thickness may alter to comply with regulations

Low E Information

External Condensation

Another issue that a small number of homeowners experience is “external condensation” on the outside of their new double glazed windows and doors. This is often after the homeowner has installed low emissivity glass (Low E Glass), which reflects heat back into the room.

This can be quite confusing for the small number of home owners who experience external condensation as in the main people are expecting reduced or no condensation once they have fitted double glazing.

In Short the “problem” is caused by the fact that the Low E glass is doing its job so well and reflecting heat back into the room.

Condensation on External Glass Surfaces

External condensation (dew) can occasionally occur on highly insulating glass units in temperate climates. Such occurrences will only happen on cloud-free nights when there is little or no wind and usually when a warm front follows a dry spell.

The combination of several factors, namely external air temperature, localised microclimate and the thermal transmittance of the glazing itself may all contribute to the formation of external condensation.

As a consequence of variable temperatures and localised conditions, it is possible to experience a situation whereby both clear and ‘misted’ windows exist at the same time in the same development.

However, the combination of contributing factors is largely unpredictable and therefore it is not possible to quantify the number of occasions when external condensation will occur. Instances of external condensation are relatively rare and in all cases it will be a transient effect. Upon any one of the climatalogical variables changing, the condensation on the glazing will usually dissipate within a short period of time in much the same way as morning dew.

The Double Glazed glass units have a manufacturers guarantee for 10 years and the installation for 2 years
