Glazing

The glass you specify when buying a roof lantern can have an impact on your rooms temperature and energy efficiency, so it’s important to choose the correct specification for the orientation of your home. We offer a range of high performance glazing options to be used with our lanterns and they are available in a range of specifications and colour options.

Specifying the correct glass

North or East Facing

North or east facing locations will tend to be shady and cool receiving little direct sunlight. Glass with high light transmission and low solar rejection is a great choice as it will allow more heat and light to enter the room and warm the space.

South or West Facing

A south or west facing location may be in the sun for most of the day, which brings lots of bright, natural light. The heat from the sun can also mean the room becomes too bright or unpleasantly warm, unless the correct glazing is specified. Choose glazing which has a low level of light transmission and higher levels of solar rejection.

Conservaglass

The position of a roof can have a direct impact on the design. South facing sites receive more sun than North facing. The need for ventilation and shading will also vary and effect the choice of glass. The % of solar gain is the measure of how much solar energy passes through the glass e.g. Standard Blue has a 49% solar gain meaning 51% of the solar energy is rejected and will not pass through.

Overview

• All roof units are toughened safety 4mm glass - 16 mm Argon gas filled cavity - 4 mm glass with warm edge spacer as standard - better winter comfort.
• Roof units are guaranteed for 10 years.
• Conservaglass is true 'Self Cleaning' with solar control properties.

Colour Options

Please Note: Due to variations in screen technology and personal display settings, the glass colours seen on your display may differ from the actual colour of the delivered product.

Conservaglass Specification

Definitions

Light Transmission - Percentage of light transmitted through the unit.

Solar Rejection - The proportion of the sun’s energy that is rejected. The higher the percentage the better it is.

U Value w/m2 - A measure of how good the material is at preventing heat loss to the outside. The lower the figure, the more thermally efficient it is.

UV Protection - The higher the percentage, the lower the possibility of furniture and fabrics fading.

* Clear coating gives a slight grey appearance.
