Step 3 – Now apply the second layer of insulation following the instructions shown in step 2, however this time ensure there is an overlap of 50mm. Mechanical parts like light fittings, etc should be cut around to ensure access. Manufacturers now produce medium- and high-density fiberglass batt insulation products that have slightly higher R-values than the standard batts. The denser products are intended for insulating areas with limited cavity space, such as cathedral ceilings. Polyisocyanurate or polyiso is a thermosetting type of plastic, closed-cell foam that contains a low-conductivity, hydrochlorofluorocarbon-free gas in its cells.

Good for adding insulation to existing finished areas, irregularly shaped areas, and around obstructions. Common facing materials include kraft paper, white vinyl sheeting, and aluminum foil. All of these materials act as a vapor barrier and an air barrier if the joints between the insulation boards are taped and sealed. Aluminum foil can also act as a radiant barrier. Your climate and where and how you're installing the insulation in your home will determine what type of facing and/or barrier, if any, you'll need. Phenolic (phenol-formaldehyde) foam was somewhat popular years ago as rigid foam board insulation. It currently has limited availability as a board insulation and is also available as a foamed-in-place insulation.

One variation of fiberglass loose-fill insulation is the Blow-In-Blanket System® (BIBS). BIBS is blown in dry, and tests have shown that walls insulated with a BIBS system are significantly better filled than those insulated using other forms of fiberglass insulation such as batts because of the effective coverage obtained by this method of application. The outer aluminium foil layers increase the overall thermal performance of the product, this is due to its high reflectiveness. Slag wool, a man-made material from blast furnace slag (the waste matter that forms on the surface of molten metal).

Most effective at preventing downward heat flow, effectiveness depends on spacing and number of foils.

Boric acid-treated insulation panels are also available. These panels deter insects, but are relatively harmless to humans and pets. Once happy that the proposed solution meets the criteria for your project, we provide you with full calculations and certifications to support your building regulations application. If needed, we can even speak directly to building control on your behalf to ensure the project progresses smoothly. Fiberglass consists of extremely fine glass fibers and is one of the most ubiquitous insulation materials. It's commonly used in many different forms of insulation: blanket (batts and rolls), loose-fill, and is also available as rigid boards and duct insulation.Firstly, measure the size of your conservatory roof and calculate the amount of insulation required. ThermaWrap is the UK’s leading reflective DIY insulation brand, offering high thermal performing products at a cost-effective price.

The outer aluminium foil layers increase the overall thermal performance of the product – this is due to its high reflectiveness. The type of insulation you should choose depends on how you will use it and on your budget. While closed-cell foam has a greater R-value and provides stronger resistance against moisture and air leakage, the material is also much denser and is more expensive. Open-cell foam is lighter and less expensive but should not be used below ground level where it could absorb water. Consult a professional insulation installer to decide what type of insulation is best for you. SIPs can be produced in various sizes or dimensions. Some manufacturers make panels as large as 8 by 24 feet, which require a crane to erect. Over time, the R-value of polyisocyanurate insulation can drop as some of the low-conductivity gas escapes and air replaces it -- a phenomenon is known as thermal drift or ageing. Experimental data indicates that most thermal drift occurs within the first two years after the insulation material is manufactured.Brilliant stuff I use it regularly...even in my own home sf19 on the outside of the roof rafters and sf40 on the inside...
