Introduction

scope of the UK structural design guide

This document is principally designed for use with the BBA certified

Victorian Roofing System, usually of floor plans up to 30m2.

For larger structures the Ultraspan Mini-Portal, an “off the shelf”

system is available for up to 7.5m clear spans, whilst a full bespoke

aluminium portal system for 7-12m clear spans is available. Over

this size and the company will employ steel portal structures.

This guide should be used in conjunction with Ultraframe’s Survey,

Fabrication and Installation guides (see page 3).

Introduction

U L T R A F R A M E is Europe’s leader in the

design and manufacture of conservatory roofing systems.

It’s products are fitted every day by discerning conservatory

installation companies - from small, local building and

joinery businesses through to the many nationally known

home improvement companies. One thing links them all

together - they are “safe in the knowledge”.

authority/accreditation

No direct British or International standard exists currently for

conservatory roofing systems. Ultraframe has, therefore, sought

it’s own accreditations that will prove fitness for purpose.

Ultraframe is the only conservatory roofing company to have

both:-

• BS EN ISO 9001/9002 for design,

manufacture and supply

• BBA certification (96/3261) for it’s white

Victorian and Ultralite 500 roofing systems.

The BBA states that Ultraframe roofs will

have a “life expectancy of at least 25 years”

The Conservatory Association is a specialist division of the Glass and Glazing Federation.

Ultraframe is fully committed to the concept of one body representing the industry, writing

technical standards and promoting consumer awareness. Ultraframe is actively involved at

every level in the Conservatory Association.

In June 1994 Ultraframe was the first company to achieve ISO 9001 & 9002 for the design,

manufacture and supply of conservatory roofing systems. To this day it remains the only

conservatory roofing company with this accreditation.

Ultraframe is a member of the Glass and Glazing Federation (GGF) and is actively involved in the

Technical Working Party Committees helping to set standards of excellence for the future and

ensuring that current requirements are adhered to.

Ultraframe has always been the design leader in conservatory roofing systems. Continuous

investment ensures that it will remain as Europe’s leading manufacturer of innovative products,

and the achievement of over 300 UK, European and Worldwide Patents is evidence of this.

In addition to authoritative testing by the government backed approvals body, the BBA,

Ultraframe uses many other independent testing agencies such as Warrington Fire Research

Centre, Leyland Test Centre and Bradford University.

Introduction


how to use this guide

It is important to read this guidethoroughly before design work begins.

Either photocopy the full size flow charton page 4 or use the “tear out” sheets inthe pad provided with the pack. Carrythe flow chart sheet with you throughoutthe guide, making important notes alongthe way.

Date, reference and sign the completedform and keep it in your project file.


flow chart

These Guidelines cover domestic conservatories of floor area less than 30 square metres at ground level which are exempt from Building

Regulations. However many of the general recommendations given in these guidelines are applicable to all conservatories. These

guidelines cover conservatories fitted to existing buildings. For conservatories built as part of new buildings these guidelines should be

used in conjunction with the Building Regulations.

These guidelines are up to date as at June 99 and are intended for guidance only. Compliance with these guidelines does not itself confer immunity

from any legal obligations. You should obtain appropriate advice and/or consult with the relevant local authority on the specific details of the

intended work.

Supporting structure:- All supporting side frames incorporating window profile material, ie PVC, timber or aluminium, should be designed in

accordance with the relevant British Standards for vertical and lateral loadings. The side frames/walls must provide conservatories with overall

lateral stability and resistance to axial loading. For specific guidance consult your side frame system supplier.

Ultraframe can supply a conservatory roof to satisfy the most unusual requests and retain

structural integrity due to our unique design skills and fifteen years experience in the industry.

The principles of these roofs and the critical details are outlined according to Ultraframe’s

product range.

All supporting side frames incorporating window profile material, ie PVC, timber or aluminium,

should be designed in accordance with the relevant British Standards for vertical and lateral

loadings. The side frames/walls must provide conservatories with overall lateral stability and

resistance to axial loading. For specific guidance consult your side frame system supplier.

Polycarbonate 6kg/m2 (0.06kN/m2)

4/4mm double glazed units 22kg/m2 (0.22kN/m2)

6/6mm (+6.4/6.4) double glazed units 33kg/m2 (0.33kN/m2)

Ultralite 500 PVC 6kg/m2 (0.06kN/m2)

Ultralite 500 PC 6kg/m2 (0.06kN/m2)

snow loading (imposed)

The requirement for snow loading applied to roofs is given within

BS 6399 Part 3 and, as a general rule, most of the UK can be

divided into two basic snow loading areas - 0.6kN/m2 (60kg/m2)

and 0.8kN/m2 (80kg/m2) and over. These areas are well defined on

the map opposite (minimum requirement of 0.6kN/m2).

wind loading

The wind loading applied to conservatory roofs is generally a

suction or negative force. The tendency is to lift the roofs up

from their supports. The load is dependant on the

geographical position within the UK, site exposure, site

topography and roof shape. The four site wind exposure

categories are defined below.

The basic wind speeds below assume that the conservatory is

not located near the summit of a hill, crest of a cliff,

escarpments or ridges. If this is not the case then advice must

be sought from Ultraframe technical department.

Any conservatories above 3m to eaves, contact Ultraframe

technical support team for advice.

City locations where the general roof height is about

25m. In very large towns

where buildings are dense and

also quite tall.

Flat undulating country with obstructions such as hedges or

walls, around fields, scattered wind

breaks, trees and occasional

buildings. Most farms and country

estates fall into this category

Areas of open and nearly level country with no shelter, ie. flat

coastal fringes, estuaries, air

fields and moorland.

Surfaces with numerous large obstructions. Examples are wooded

parkland and forest areas, towns

and their suburbs, and the

outskirts of large cities. General

level of roof tops in the area will

be about 10m

Basic tie bar rules

gable ended roofs

1

3 2

1 Position the first tie bar at penultimate glazing bar to gable

end, this is to minimise any loads imparted on the gable frame.

2 Tie bars need to be positioned in line with and directly under

glazing bars (refer to Georgian tie bar rules on page 25-28)

3 Spacing of the tie bars to be as guidelines on pages 25-28

3 On gable frame assemblies (also lean to roofs) attention should

be given to the strength required of the mullions and transoms

for resistance to wind loads (see no. 3 right)

4 The critical detail where a mullion or transom transfers wind

loads to the roof structure requires specific attention.

All supporting side frames incorporating window profile material,

ie PVC, timber or aluminium, should be designed in accordance

with the relevant British Standards for vertical and lateral

loadings. The side frames/walls must provide conservatories with

overall lateral stability and resistance to axial loading. For specific

guidance consult your side frame system supplier.

“P” shape1 Length of return ideally to be 300mm to ease fabrication of

corner with incoming valley member

2 Finial point to be positioned in line with lean-to external wall

or beyond when Victorian section width is greater than 3.0m

(glass or polycarbonate)

3 Position glazing bar and tie bar at finial position

4 Spacing of tie bars along the ridge as stated in tie bar spacing

guidelines on pages 25-28 of this guide

5 All tie bars and glazing bars MUST BE IN-LINE

“L” shape1 Length of return to be ideally 300mm to ease fabrication of

corner with incoming valley member

2 Finial point to be aligned in line with lean-to return wall or

beyond

3 Position glazing bar at finial position along with 3/5 way tie

bar as required

4 Specify 5 way tie bar in either position (*) or both if required

by width of georgian ends to support position ‘A’

5 Position tie bar in-line with return wall

6 Spacing of remaining tie bars as stated in the tie bar

guidelines

7 All tie bars and glazing bars MUST BE IN-LINE

8 Position gallows bracket/brick pier under the boxgutter at the

tie bar positions

1 The requirements for tie bars within a conservatory are

primarily dependant on the length of the ridge (measured from

house wall to finial point).

2 Loading on the roof (snow or dead) will cause a minimal

vertical deflection along the ridge length which in turn imparts

a horizontal reaction (thrust) at the eaves beam through the

glazing bars.

3 The tie bar system restrains the horizontal reaction minimising

horizontal spread of the eaves beam.

4 Tie bars should always be positioned in line with and directlyunder glazing bars (forming a vertical triangle) and supporting

the ridge.

5 Standard fixing detail is to the glazing bar with bracket

connection to eaves beams and other areas possible though

advice should be sought on individual instances.

corner post selection and use

135° Corner Post 150° Corner Post

Ultraframe supply a range of corner posts to suit all frame thicknesses and profile colours, including mahogany and light oak.

These can provide vertical support for the roof transferring loads from the eaves beam to the base of the conservatory. This avoids

over stressing the side walls of the conservatory which may not have been designed to support the roof.

• Based on 0.6kN/m2 snow load and 6/6 double glazed units, total load is 0.93kN/m2 ie approximately (1kN/m2)

• A 2.1m high 150º corner post has a safe load capacity of 7.3kN, which is equivalent to supporting an approximate area of 7.3m2

• Window profile must be positively fixed to the corner post at 500mm centres min.

guidelines for use

Generally use standard multi-eaves beam, except as below.

Use the heavy duty multi-eaves beam for these roof types-

• Glass

• Where tie bars are included

Ultraframe recommend the use of victorian fixing kits on allroofs when possible

Multi-eaves beam

Ultraquick

Eaves beam charts based on eaves beam spanning between posts with tie bars aligned with posts / frame stiffener

Victorian roofs: three bay & five bay - maximum width of roof recommended

when using Ultraquick is 4750mm for polycarbonate glazing &

4250mm for glass.

Georgian roofs: square fronted - maximum width of roof recommended when

using Ultraquick is 4250mm for polycarbonate glazing &

3900mm for glass.

Lean-to roofs:width of roof should not exceed the spans recommended for

glazing bars (see glazing bar loading graphs for information)

For conservatories in excess of the above sizes, we recommendusing heavy duty multi-eaves beam
