For over 20 years now Ultraframe has been the acknowledged market leader in the design and manufacture of conservatory roof systems. With over one million Ultraframe roofs already installed throughout the UK, the pedigree and quality offered by our roof systems is second to none. During this time Ultraframe have developed a widely recognised set of guidelines by which conservatory roofs are designed, speciï¬ed, ordered and installed.
Ultraframe have complied this manual to explain and translate much of the jargon used in the conservatory industry. We have listed many of the commonplace words and terms used daily in connection with conservatory design and installation.
Each reference includes a list of possible alternative words (“also known as”), a full description of the product/component and a full colour picture, where appropriate, to illustrate its relevance.
To find the explanation for your jargon term just browse the terms alphabetically below or Search Our Site.
Also known as: Toughened glass, laminate glass or Georgian wired glass
There are different types of safety glass but the most prevalent is toughened glass. Toughened glass is made by quickly heating the pre-cut sheet glass and air cooling it rapidly, changing its molecular structure. Laminated glass is produced by permanently bonding two pieces of glass together with a tough plastic interlayer (polyvinyl butyral) under heat and pressure. The benefit of laminated glass is that if broken, glass fragments adhere to the plastic interlayer rather than falling free and potentially causing injury. Georgian wired and laminated glass are not used very often in conservatories.
Also known as: Levelling material
Layers of sand that cover the compacted hardcore within a base.
Also known as: Levelling compound
Layer of concrete floor to level for the fitting of floor tiles.
Also known as: Low modulus, Rotabond, Gutterbond
Special sealants are used by installers for achieving leak-free conservatories. The two main types are as follows: Low modulus neutral cure silicone
Also known as: Double glazed unit, IGU
Also known as: Hot melt
A secondary seal on an IGU. See page 17
Also known as: Solar heat gain coefficient
Solar heat gain coefficient refers to heat from the sun which penetrated glass units, resulting in heat gain. It is expressed as a fraction; i.e. 0.40 = 40% of the sun's heat penetrates the conservatory.
Also known as: Fabricated end
See fabricated end (the image shown is a slotted fabricated end for a lean-to). Formed from aluminium.
Also known as: Snow drift
Snow load refers to the amount of snow that should be able to settle on the roof of a conservatory without it collapsing under the resulting weight. Conservatories in Britain are typically designed to a snowload of 0.6Kn/m2 (equivalent to 2 foot of snow per m2).
Also known as: Runaway
A hole that's dug typically 5m away from property for water to run into.
Also known as: Weathering tray, lip, upstand
A preformed upstand which lead or conservaflash is pressed into.
Also known as: Under eaves board, Roofline
A soffit board is the horizontal board that lies at 90 degrees to the fascia; i.e. parallel to the ground.
Also known as: Sputtered microscopic layers
Soft coating is the coating applied to the outside face of the inner pane to significantly improve unit thermal performance. Pilkington K is a hard coat product, St Gobain (the other leading glass manufacturer) produces soft coat products.
Also known as: Foul Stack
Main vertical pipe which waste water and foul water run into
Also known as: Slab, plinth
A concrete floor slab constructed and supported directly from the ground.
Also known as: Spacer barA spacer is a packer (usually metal) which forms a cavity width within a double glazed unit.
Also known as: Span
Spanning performance is the term used to describe the ability of a structural member to carry snow and wind loads between fixed points; e.g. glazing bars, ridges. The larger the span, the more demanding the specification is the achieve the span.
Also known as: Spider arms
A speedlock is the device used to connect square cut glazing bars to the ridge end.
Also known as: Angled bars
Glazing bars that cross (& fasten to the eaves beam) at any angle other than 90 degree.
Also known as: Bent valley, Cut valleyA split valley occurs where the valley meets the eaves beam. If the external angle exceeds 90 degrees the valley wind (on the facet side) will need to be scored, folded and then bolted to the eaves beam, to enable the glazing material to lay flat.
Also known as: 135degree formed bricks
Typically formed at 135 or 150 degrees to offer 'feature' corner facets to a brickwork dwarf wall.
Also known as: Stepped jack rafters
Jack rafters either side of a hip bar that are not back to back.
Also known as: Wall bar, end bar, gable end bar
The starter bar is the end bar on a roof which either sits tight to a wall or fits on each end of a lean-to roof.
Also known as: Outlet
A conservatory roof stockist is someone who simply stocks conservatory roofs to sell them non via a trade counter to installers; i.e. they do not manufacture or install products.
Also known as: Wall outlet
A stop end outlet is used when a run of gutter stops with a rain water pipe outlet.
Also known as: Setting out point
Used by bricklayers to form set out lines for straight brick work building (corner to corner).
Also known as: Glazing bar
See 'Glazing Bar'.
Also known as: Vertical and lateral stability
A well designed conservatory has structural integrity; i.e. it takes account of wind and snow loads and incorporates features to make it fit for purpose, e.g. includes TBRK, Bolster, etc.
Also known as: Super hero!!
A surveyor is the person responsible for site evaluation and measurement to ensure the conservatory to be manufactured and built will be suitable for the site conditions.
Also known as: Floating floor, block and beamA suspended floor is a floor construction raised and suspended above the internal ground level and generally supported by the perimeter cavity walls, with possibly load bearing internal masonry walls to reduce the span of the floor.
