5 Heat Transfer Principles HEAT TRANSFERS IN THREE DIFFERENT WAYS Convection Movement of a fluid due to a difference of temperature and density. The hot air goes up and heat is dissipated. With a ventilated roof, the heat located in the air gap between the hedging and rises and is then ventilated through the roof covering. Conduction Transmission of heat from body to body by contact. The more insulating the material is, the less there is conduction. The λ characterisic measures the conduction in a specific material. Thermal Radiation The heat transfer without contact between two bodies. All material absorbs and emits thermal radiation according to its temperature. The raditaion from a UV lamp alone can cause the burning of a sheet of paper without any direct contact. 5

6 What is a roof tile underlay (RTU)? A roof tile underlay has the following functions: Protect from water, snow, dust, soot filtration, intrusions of insects and birds, and slows down pollution. Redirects the condensation and infiltrated water down the roof to the gutter. Protects the roof structure until the roof cover is fully installed. Prevent the upheaval of the roof s elements under the wind effect by counterbalancing pressures (Wind Uplift BS 5534). Assure air tightness of the roof in order to prevent cold air infiltration and keep warm air inside. Two different kinds of roof underlays: Breathable and Non Breathable Breathable (HVP) Closed envelope Non breathable Open envelope HVP = High Vapour Permeability (Breathable) Type of Underlayment Traditional Non HPV Underlay HPV Underlay () Ventilated underside and tight exposure Direct exposure on insulation Exposure Type Exposure on continuous and ventilated upper side support Closed envelope exposure X X X X X 6

7 Functions An Insulating, Breathable, Waterproof and Airproof Barrier. Because is highly breathable, it can be used to completely seal your attic without risk of condensation. Your house can be completely sealed with excellent thermal performances. As it is breathable, will prevent condensation - which is a main cause of roof structure failure. 7

8 1 st FUNCTION: Reflective Insulation and Low Emissivity Very low emissivity (emissivity = 5 %) WINTER SUMMER Very high reflectivity 95 % Very high reflectivity 95 % Emissivity 5 % Heating system Air conditionning In Winter: will maintain the heat generated within the home, creating a thermal barrier to protect you from the elements. In turn, this low emissivity considerably reduces radiation losses to the outside. As result, this reduces your energy consumption. In Summer: is an excellant thermal barrier and reflects the solar radiation back outside to prevent over heating of the attic space. s low emissivity and reflective insulation limits the thermal radiation to the roofspace. As result, this reduces air conditioning consumption 2 nd FUNCTION: Sealed Insulation: Waterproof and Airtight Waterproof rain barrier Drives eventual water leaks to the gutter Air and vapour exhaust Water vapour coming from inside attic can escape in the ventilation space (Roofing Membrane) Airtight wind shield Ventilated roof air gap Hot or cold air leaks Water vapour Weather barrier (application under external wall cladding) Heated or cooled living space Water vapour due to human activities Air entrance 8

9 Other Advantages TIME SAVING INSTALLATION Instaling is quick and easy! Installation time is halved: Install just 1 product:, instead of 2 seperate products (Reflective Insulation & Roof Underlay). INCREASED LIVING SPACE An average gain of: +5% in the walls +15% in attic space The reflective insulation of allows the frame structure (beams, purlins) to be left open. SUSTAINABLE & LONG LASTING INSULATION s reflective insulation is composed of continuous glass filaments having high mechanical strength. These filaments, also used as reinforcement in composites, have a life span of 50 years. These filaments discourage the nesting of rodents. HEALTHY COMPONENTS reflective insulation is guaranteed to be Asbestos Free and without any chemical bonding. is non-toxic and non-irritant (Group 3 of iarc). It s filaments are classified noncarcinogenic by the European Directive No. 97/69/ CE. requires no specific equipment for installation, with the exception of sunglasses when installing outdoors due to it s high reflectivity. is 100% recyclable and made of over 90% recycled materials. FIRE PROTECTION Euro classes - Test SBI - LNE has obtained a European certification of non-combustibility (Euroclass A2-S1-d0). As is non-combustible, it will protect your roof structure from wild fires and can be installed directly to your chimney flue. 9

13 Installation Guide PROTECT YOUR EYES! is highly reflective. When installing it outside, sunglasses must be worn for eye protection. INSTALLATION can be used with any type of roof covering (metal, tiles, slates etc.); and for new and refurbished projects. Due to its fire protective properties, can also be used to upgrade a roof s fire performance in fire exposed areas. can be used with any type of building, in any climate conditions. must be laid tightly, horizontally accross the construction s frame (parallel with the drains) starting from the bottom, without any ventilation on the inside face. Installation Direction should be installed with the black lined side facing outwards. Tape: Adhesive Aluminium Tape The fire rating Euroclass A2-S1-D0 can only be guaranteed with the use of Tape, where it is used to cover/ seal the joins. BE CAREFUL protect your eyes Tape must be applied on a dry and clean surface that is free of contamination (e.g. without dust, oil and grease). It is very important to apply sufficient pressure on the tape during application to ensure secure bonding. Tape must not be applied in temperatures below 5 C. Temporary Water Protection During normal weather conditions, the properties of and Tape contribute to a temporary water protection for up to 8 days, when installed together. 13

14 Distance Between Rafters The high breaking strength and resistance to nail tearing allows to be installed with a 900mm maximum distance between rafters. Fixing The primary fixings are those used as standard to fit roofing materials to the roof frame (battens and counter battens). However to temporarily fix on the supports, it is advisable to use clout nails or staples on the rafters. To seal the courses (overlaps) together, use the adhesive TAPE. Oxidation In order to prevent oxidation, avoid coming into direct contact with copper, brass or lead. Overlap on Roofs For installation on the roof, the strips should be held horizontally (parallel to the drains) across the roof structure, starting from the bottom. The minimum amount of overlap of each course of has to be considered in relation to the pitch of the roof, as follows: Solar Panel - Roof pitch 30% = 200mm - Roof pitch 30% = 100mm A solar panel should be considered as a roof cover element and therefore should be installed following manufacturers instructions. 14

15 The Air Space between and the roof cover (Outside face of ) The air gap between the roof cover and should be formed of atleast 38mm thick counter battens on roof structures shorter or equal to 26 foot in length. On roofs structures in excess of 26 foot in length, an airgap of 58mm is required. The Air Space on the underside of (Inside face of ) This air space located under should not be ventilated. The very high permeability of allows it to be applied directly to existing insulation or on sheathing (continuous supports). There should be atleast 0.8 inches (20mm) between existing insulation and. This results in an increase in thermal efficiency. When thermal insulation is laid, it is not mandatory to develop a ventilated air space between the insualtion and. The presence of a non-ventilated air gap on the underside of helps to limit winter heat loss from the inside. 15
