Style Of Roof Spacer image

Dimension A (mm) Spacer image

Upstands Height (mm)
(Enter 0 if not required) Upstands are optional, and are an extra over cost. Upstands are the fixed side windows under the roof, that can be specified to raise and support the roof lantern. They are designed to let in more natural light. They must be at least 300mm high and are generally between 300mm and 350mm high.

Are These External Sizes? Spacer image Please let us know if you are providing the internal or external measurements for your roof.

Also please be sure that when you survey / design your roof, you take into account any fitting tollerances. We cannot do this for you as it would be impractical for us to do so, when we have not been out to site. The sizes you provide are the sizes we manufacture to.

Pitch in Degrees (optional) Spacer image Our roofs can have a pitch of between 5° and 45°. Alternatively if you are unsure what pitch you would like, we can suggest a sensible / conventional angle for your roof.

Colour Spacer image Please choose a colour for your roof. Some common colour options are listed, but you can also have your roof dual coloured. Dual colour is where you have one colour on the inside of the roof and a different colour outside (e.g. black outside, white inside)

Glazing Type Spacer image There are many glass types available all of which are double or triple glazed, or you may opt to have more economical Polycarbonate sheets. . You can also request to have our roofs supplied unglazed, if you wish to source your own glass. Some common options are given here.

We always recommend to people to use double glazed glass sealed units in our roofs. This is due to the fact that glass has superior load bearing and acoustic properties. Glass also offers other attractive options, such as self cleaning and solar control glass.

Ring Beam Type Spacer image We offer two ring beam types, a standard ring beam and structural ring beam. The standard is the most common and cost effective choice. A structural ring beam is generally only required when a roof spans a large unsupported opening - such as a bi-folding door. Bi-fold doors are not load bearing and cannot have any weight pushing down on them, so we would recommend a structural ring beam to take the full weight of the roof. The structural ring beam is massively over-specified with thicker aluminium walls and a cross brace design, and it can save you money when compared to specifying steels.

Image shows our ring beams, structural on the left, standard on the right.

No. Electric Roof Vents Spacer image Roof vents are opening windows in your roof. Our electric roof vents can be operated using a simple rocker switch, which we can supply upon request.

Our Combined Heat & Rain Sensors allow you to set your electric roof vents to automatically open or close the roof vents when it gets too hot inside the room or when it rains outside.

Vent Control Type Spacer image

No. Manual Roof Vents Spacer image Roof vents are opening windows in your roof. A crank handle is turned to operate our manual roof vents (gearing and crank handle not supplied).

Guttering Required ? Spacer image Our aluminium roof system is a fully aluminium system. As a result we can supply standard aluminium rain water guttering in any RAL colour, painted to match the rest of your roof. We do not however supply basic plastic guttering.

Metres of Box Guttering
(If Required) Enter the length of Box guttering you require, to the nearest metre. Box guttering is not just any guttering but a special deep gutter system to go between two pitched roofs. If an existing roof and your new roof join in a V shape, then a box gutter would be required at the bottom of the V where the two roofs join.

The box gutter is a U shape and oversized to take the large volume of water entering from both roofs. Aluminium rainwater guttering can also be supplied, if required. Please see question further down the form.
