Wooden Secondary Glazing


Our custom made wooden frame secondary glazing is of the highest quality.

By controlling the design and manufacture of the wooden frames we can accommodate and create a custom system to incorporate or be complimenting many styles and opening options for any project. We can create a hinged or sliding internal window made from timber to sit sympathetically behind the original window. This will offer significant noise reduction and improved thermal performance without the presence of inappropriate modern materials in the room.

Why choose timber windows frames for secondary glazing system:

Timber – for long-term value
Maintenance and repair of timber is both cost-effective and easy. Modern timber treatments ensure that our product will have a long life. whilst good paint systems will need no attention other than cleaning for many for those years. Repainted timber windows look as good as new and lift the appearance of any property.

If damage occurs to a timber window or door it can be easily repaired leaving no sign of the repair. It is not surprising therefore that timber is increasingly seen as the material of choice for long-term value.

Timber – natural quality

Few materials can compare when it comes to the look and feel of a good quality timber window frame. Warm to the touch and pleasing to the eye, real wood gives a sense of natural quality and durability.

Thermal Insulation and draft reduction.

Secondary glazing supplies and installed by APG. Can reduce heat loss from existing single pane glazing by up to 50%. Double glazed secondary glazing, incorporating a heavy duty frame will allow a fixed unit with a low-E coating can achieve a much lower  Uvlue rating for your window. Surround draught proof design will reduce unwanted air ingress.

Noise reduction.

Distributive noise levels can be a real detriment to the enjoyment of your home or working environment. Installing effective secondary glazing can be a cost effective way to significantly reduce this external nuisance. In these Situations APG can specify enhanced acoustic glass or laminated glass of 6mm plus thickness as an effective insulating secondary glazing system.
