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

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
