Celsius Solid Roof System Description of Product

This is an assessment of the Celsius Solid Roof

system manufactured by Aperture Group. It is

a lightweight solid roof intended as an

alternative or a replacement to glazed roof

systems on conservatories.

This Registered Solution applies to the roof

only. It is designed to fast-track, not remove,

the requirement to obtain Building Regulation

Approval through LABC. This can only be

demonstrated through a Completion Certificate

issued following satisfactory inspections made

as part of a valid Building Regulation

application by Local Authority Building Control

teams.

For Scottish purposes such alteration works

require Building Warrant approval.

Key Factors Assessed

Mechanical Resistance & Stability

Safety in case of Fire

Health, Hygiene and Environmental

Safety in Use

Energy Economy and heat retention

Durability serviceability and identification

Certificate No: EWS550

This is an assessment of a specified and accredited lightweight, solid roof system for use on conservatories and sunrooms as an

alternative to or a replacement of a traditional glazed roof system.

The roof system is designed to give a satisfactory level of thermal insulation, weather resistance and structural stability.

The roof system consists of a Structural Insulated Panel (SIP) system with a breathable membrane and recycled polymer roof

tiles.

The system can be used on new structures or existing structures subject to the suitability of the existing structure. The existing

structure will need to be assessed to ensure its adequacy for taking any additional loads and may include exploratory

investigation of the existing construction.

Approved Document L1B states that the amount of glazing allowed to an extension is 25% of the floor area. In order for this

limitation not to apply, there should be:

1. Effective thermal separation must be maintained between the dwelling and former conservatory or porch.

2. Any existing independent temperature and on/off controls to any heating system installed within the former conservatory or

porch may be maintained.

Refer to Technical Guidance Note MG0010411 Application of Part L to Conservatories attached to existing dwellings https://www.labc.co.uk/sites/default/files/labc_4893_techg_conservatories.pdf and LABC guidance on solid roofs to

conservatories and porches attached to dwellings https://www.labc.co.uk/sites/default/files/Solid-roof-conservatories-guide-

The roof specification designed to achieve 0.18 W/m2K comprises;

Metrotile Shingle or Envirotile interlocking ventilated roof system installed in accordance with BS:5534-2003 fixed over Nilvent

breather membrane on 142mm Kingspan TEK panel. Panel comprises two external 15mm OSB boards with 112mm PUR

insulation with 110mm joint cassettes. Internal finish comprises 12.5mm plasterboard and skim. Installed in accordance with BBA

certificate 02/S029.

A tiewire manufactured by Instructures Limited may be used as an alternative to a tie bar for use in the roof system. The static

load limit of this fitting is established as 15Kn.

The manufacturer shall exercise permanent internal control of production. All the elements, requirements and provisions adopted

by the manufacturer shall be documented in a systematic manner in the form of written policies and procedures, including

records of results.

This production system will ensure the product is in conformity with the relevant approval.

The manufacturer may only use components stated in the technical documentation.

For Scotland purposes:

The roof specification in Scotland designed to achieve 0.15 W/m2K comprises;

Envirotile interlocking ventilated roof system installed in accordance with BS:5534-2003 fixed over Nilvent breather membrane on

142mm Kingspan TEK panel. Panel comprises two external 15mm OSB boards with 112mm PUR insulation with 110mm joint

cassettes. Internal finish comprises composite 30mm insulated 12.5mm plasterboard and skim. Installed in accordance with BBA

certificate 02/S029.

Installation should only be undertaken by competent installers to the specifications as shown and described in the manufacturers

installation guide. Light fittings should not penetrate the vapour barrier. Existing structures should be checked for structural

adequacy prior to the installation of the roof. A suitable flashing design should be agreed on site where pipes pass through the

roof construction.

Any flues passing through the roof should be installed in accordance with BS EN 1856 – 1: 2003. Approved Document J –

Section 1 Provisions which apply generally to combustion installations and in Scotland with Mandatory Standard 3.19

Combustion Appliances – relationship to combustible materials.

Effective thermal separation between the conservatory and existing dwelling should be maintained.

The Registered Detail relates to the reroofing of existing conservatory or porch roofs that satisfy the requirements of Schedule 2,

Class 7 to the Building Regulations 2010 (as amended); i.e. It must be at ground level; it must not exceed 30 m2 in floor area;

the thermal separation between the building and the conservatory or porch must be maintained; and the building’s heating

system must not be extended into the conservatory or porch. If the thermal separation is removed then a separate Building

Regulation Application needs to be submitted and the amount of glazing to the former conservatory or porch should be

reduced to less than 25% of the floor area and the glazing should achieve a U-value 1.6W/m2.K (alternatively heat loss

calculations may be used).

For Scotland purposes:

The Registered Detail relates to the reroofing of existing conservatory roofs but does not negate site specific issues relating to

the affect the installation of a solid roof may have on any inner room accessed or covered by the re-roofed conservatory. These

site specific issues will be assessed under a building warrant by the relevant local authority.

That the specifications and materials referred to have been assessed and approved in accordance with the Building (Scotland)

Regulations 2004 and in accordance with the supporting guidance in the Domestic Technical Handbooks which came into force

with effect from 1 October 2013.

That where reference is made on a plan or specification document to any Code of Practice, British or European Standard or

manufacturer’s instruction it shall be construed as a reference to such publication in the form in which it is in force at the date of

this Registered Detail.

That the materials specified shall not be changed without first gaining approval so to do. Failure to do so will invalidate the

Registered Detail.

This Registered Detail should not be regarded as a formal approval under the building warrant process prescribed by the

Building (Scotland) Act 2003 enacted from 1 May 2005.

That this Registered Detail shall contribute to compliance with relevant Mandatory Standards specified under the Building

(Scotland) Regulations 2004 as amended when read with the Limitations of Use Section to this Registered Detail.

LABC and LABSS consider that, the Celsius Solid Roof system, will meet the functional requirements of

the Building Regulations (listed below) if the criteria detailed in this certificate are met;
