All our conservatories come with 'A' Rated glass in the windows and doors. An ‘A’ rating is currently the highest rating a double glazed window can achieve.  The units are all argon filled. Air is a very good insulator, but it’s not as good as Argon gas. By removing the air from the cavity and replacing it with argon, an extra barrier to heat loss is created.

Rather than a cold metal spacer frame, our sealed units use a modern composite polymer material which is up to 950 times less conductive than aluminium. When you come to sell your home you will need to produce an ‘energy certificate’ within your home information pack (HIPs). This tells potential purchases how energy efficient your home is. By investing in a Conservatory World conservatory today, you will make your property more marketable.

Glass or polycarbonate

Conservaglass is a high performance glazing material, unique to Ultraframe. Conservaglass allows you to use your conservatory all year round by keeping heat out from the sun during Summer whilst retaining warmth from heating appliances during Winter. Especially developed for UK weather conditions, a glass roof allows you to enjoy a view of the sky by day or night. Conservaglass is available in Neutral Clear or Subtle Blue. Polycarbonate, the alternative to glass is available in a range of colour options to complement your exterior frames. Choose from clear, opal, bronze or bronze/opal or solarguard in either 25mm or 35mm thick panels. The different colour options have different properties for controlling heat/glare.

Frosted Glass
An alternative name for patterned glass, good for privacy. more

Georgian Glass
Georgian glass or Georgian wired glass is another form of safety glass. Thin square wires run between the double glazed unit. When broken the wire holds the glass together.

Glass U-Values
A thermal conductivity reading. The U value signifies heat loss performance (insulation factor); the lower the reading the more efficient, i.e. polycarbonate with a ‘U’ value of 1.6 is better than Ultralite with a ‘U’ Value of 1.9.

Heat Reflective Glass
Heat reflective glass has a special coating on one side which reflects solar energy away from the glazing. Solar heat gain co-efficient refers to the amount of heat which penetrates a glass unit, resulting in heat gain. It is expressed as a fraction i.e. 0.40= 40% of the sun’s heat penetrates the conservatory.

Laminated Glass
This is produced by permanently bonding two pieces of glass together with a tough plastic interlayer (polyvinyl butyral) under heat and pressure. When broken the glass fragments adhere to the plastic interlayer rather than falling free and potentially causing injury.

Leaded Glass
Larger pane of glass, split into smaller pieces using lead beading to keep the coloured glass separate. Used extensively in churches and Victorian times

Self Cleaning Glass
Uses a special coating that is bonded into the surface of the glass when its molten – suns energy burns off organic deposits whilst the rain ( or hosepipe in dry summers) irrigates the glazing to wash off the deposits that the sun has brocken down. See Pilkington Activ™ Self-Cleaning Glass

Toughened Safety Glass
Toughened glass is the most prevalent of the safety glasses available. Toughened glass is made by quickly heating the pre cut sheet glass and air cooling it rapidly, changing its molecular structure
