Purchasing a conservatory is a major decision, which depending upon the size, quality and design can be a significant investment. Other key considerations are, of course, style, appearance and comfort though it’s here where the glass you choose makes all the difference. You want your conservatory to look good and to suit your needs.
Nowadays the potential uses of a conservatory are as diverse as the designs available. Some are looking to add extra living space that can be used year round as a dining room, children’s playroom, home office or similar, while others are looking to create a seamless, visually connected link between home and garden.
Our conservatory roof glass range offers you a choice of four attractive tints all with low maintenance self-cleaning.
Each glass tint offers its own combination of solar control and glare reduction properties as well as an individual character to suit your own.
Specify SGG PLANITHERM 4S conservatory wall glass with any of our roof options to obtain the ultimate combination of a cooler summer environment and warm, cozy winter months.
Self Cleaning Glass provides you with clearer views for much longer and less cleaning. However it is not 100% maintenance-free.
For those stubborn stains such as bird excrement and tree sap, South Lakes WIndows Ltd have a recommended list of cleaning and maintenance products designed specifically for use with Bioclean conservatory roof glass. For details contact South Lakes Windows Ltd.
Percentage of light transmitted through the unit.
A low % can reduce glare from the sun.
The proportion of the sun’s heat that is rejected. Generally the higher the percentage the better the glass is. However, if you have a North facing or shady site you may want solar rejection to be lower.
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.
All Conservaglass is self cleaning and specially designed to remain cleaner for longer than conventional glass. The transparent coating on the glass harnesses the power of ultra-violet rays from the sun and rain (or water) to break down dirt and grime, then wash it clean away.
The higher the percentage, the lower the possibility of furniture and fabrics fading.
All our glass is toughened, double glazed safety glass: 4mm glass – 16 mm Argon filled cavity – 4 mm glass, with black warm edge spacer as standard. It is manufactured in specialist roof glass factories and guaranteed for 10 years.
