Largely manufactured from recycled glass (e.g. windscreens) and mineral base materials such as sand and without the use of binding agents. The ingredients are melted into molten glass, which is cooled and crushed into a fine powder. The powdered glass is poured into molds and heated (below the melting point) in a "sintering" process that causes the particles to adhere to one another. Next, a small amount of finely ground carbon-black is added and the material is heated in a "cellulation" process. Here, the carbon reacts with oxygen, creating carbon dioxide, which creates the insulating bubbles in the (material). CO2 accounts for more than 99% of the gas in the cellular spaces.
Cellulose insulation is a material made from recycled newspaper. The paper is shredded and inorganic salts, such as boric acid, are added for resistance to fire, mould, insects and vermin. The insulation is installed either blown or damp-sprayed depending on application.
Wood fibre
The success of wood fibre insulation derives from an attractive environmental profile combined with a whole bag of functions including rigid insulation, sheathing and sarking for timber frames, roofs and flooring as well as flexible insulation for studs and rafters.
Wood of course is renewable, it sequesters carbon during its growth and product production is relatively free from pollution. The insulation value of wood fibre boards is not as dimensionally efficient as some of the orthodox petro-chemical materials - but it's no slouch either - typically coming in with a 'k value' range of between 0.038-0.043 W/mK depending on format.
Hemp
Hemp fibres are produced from hemp straw of the hemp plant. Most hemp is imported, but an increasing amount of home-grown crop is becoming available. Hemp grows up to a height of nearly 4 metres within a period of 100-120 days. Because the plants shade the soil, no chemical protection or toxic additives are required for hemp cultivation. The product is composed of, usually, 85% hemp fibre with the ballance made up of polyester binding and 3-5% soda added for fire proofing.
Straw
Straw is an agricultural by-product, the dry stalks of cereal plants, after the grain and chaff have been removed. Straw makes up about half of the yield of cereal crops such asbarley, oats, rice, rye and wheat.
Reflective foil insulation, also called multilayer foil insulation is a new type of insulating product that consist of a 80% foam core with an aluminium laminate each side that allows you to create much more comfortable garage space. The way it works is, instead of slowing down heat transfer the way traditional insulation does, foil actually blocks 97% of energy transfer in and out of the door structure. Reflective foil insulation was introduced onto the market as a smart thermal insulation material. This material is clean, lightweight, recycled and more important - 5.5mm thick. Moreover, reflective foil insulation can be very easily installed as a garage door insulation. It is so easy so anybody can do this. All it needs is double sided tape. Some foil comes as a self-adhesive blanket. It is not itchy and no dangerous chemicals in the garage can ruin this type of insulation. From an aesthetic point of view it is very tidy, shiny and clean not only for you, but your family too. It is class A fire rated, mould proof and it will even help deaden sound up to 50 percent. Along with being lightweight, it is usually quick and easy to install. It can be easily cut with a stanley knife. Reflective foil insulation allows you to upgrade your garage door efficiency at very little cost to you (£69.90). This material is easily accessible at popular shops like Screwfix, Wickes or B&Q.
LOW-E™ is the most popular foil insulation brand in the UK, coming from America, where it has been used for over 20 years in various applications. LOW-E is a real game changer when it comes to insulating your garage door. It's cheap and flexible enough to bend back on itself. Its aluminum surfaces have an emissivity of 0.03, which means only 3% of radiant energy will pass through. When installing reflective insulation on garage doors, it is important to allow for sufficient space for air layers. Reflective foil is often confused with multi foil insulation. Multifoil is made up of multi-layered reflective films used in tandem with PIR board to enhance thermal performance. These layers comprise of reflective films interspersed with insulating sections, generally made from wadding. These wadding and reflective layers interact with each other to maximise the thermal efficiency of the structure in which they are applied. Multifoil insulation is ultrasonically welded while reflective foil is single reflective facing material.
REFLECTIVE FOIL INSULATION REVIEW
An air space is needed for a radiant barrier to work. By definition, you must have a void for radiant heat to even exist. If you don’t have an air space then you are basically dealing with conduction. Unlike conduction, reflective foil insulation in order to work they need space to block heat. Research indicates that foil insulation works best when it is placed near the heat source. This means that gluing it to the garage door surface is the best way to keep cold out of the garage.
