Our conservatories are built using high-quality window and door systems, so all the advantages of our PVCu windows and doors also apply to our conservatories.

A wide range of traditional and modern styles are available to enhance your home. Our experienced installers will prepare the foundations for your conservatory. Base walls can be in brick finish, rendered, or alternatively the conservatory can be glazed right down to the floor or finished with decorative panels for an attractive and modern look.

CAD drawings

The Door & Window Centre Ltd can provide you with a CAD drawing of your desired conservatory giving you a vision of what you would like. The CAD drawing is available free of charge with all quotes. Examples of CAD drawings provided by us are shown below:

Thermal Insulation

We use Kooline Activ Blue™ which contains Pilkington K glass™. This is a thermally efficient glass and therefore will keep more heat in the building. Your conservatory will be kept warm even in the coldest winter weather, making it a more comfortable environment and helping to reduce your heating bills.

Kooline Activ Blue™ sealed units are also filled with argon gas which helps to reduce the U Value of the unit and therefore make it thermally more efficient.

Kooline Activ Blue™ is the ideal double glazed sealed unit for your conservatory roof.

That’s because it’s the only insulating glass unit that combines the beneficial qualities of self-cleaning technology, solar control and thermal insulation.

Solar Control

Pilkington Activ is an attractive tinted glass that comes in “blue, green, clear and neutral”. It combines dual-action, self-cleaning properties with medium solar control performance helping to create a cooler internal environment in the summer which can be used all year round; whilst still maintaining light transmittance.

How it works

The glass manages solar heat radiation by three mechanisims: reflectance, transmittance and absorbance.

These are defined as follows:

  • Reflectance – the proportion of solar radiation reflected back into the atmosphere.
  • Direct transmittance – the proportion of solar radiation transmitted directly through the glass.
  • Absorptance – the proportion of solar radiation absorbed by the glass

Self-Cleaning Technology

Kooline Activ Blue™ contains a microscopic coating which uses sunlight and rainwater to break down and wash away organic dirt from the exterior surface of the glass unit, making it ideal for hard to reach places that are difficult to clean, such as conservatory roofs. This helps to make Kooline Activ Blue™ the perfect low maintenance unit.

How it works

The coating has photo-catalyctic and hydrophilic properties, and works in two stages:

Stage 1 – The coating reacts with natural daylight to break down and loosen organic dirt.

Stage 2 – when it rains, instead of forming droplets, the water spreads evenly over the surface of the glass, helping to wash away any dirt and reduce streaking.
