From time to time certain building products can fall into short supply. This can be for a number of reasons, such as the housing market is booming and factories just have not got the extra capacity to cope with the increase in production.
Alternatively it could be that the raw products required to make these materials are in short supply. Such as we have experienced over the last year with insulation blocks. This is where we have mild winters and people don’t use as much electricity to warm their homes. This in turn affects the coal fired power stations whose bi-product is one of the raw materials used to make insulation blocks.
At the time of writing we are experiencing a huge shortage in PIR insulation. Mainly due again to one of the raw chemicals used in the production of this type of material being in short supply. In November 2016 a factory that supplied a chemical that is used in the manufacturing process of polyisocyanurate burnt down. This over 2017 has created an ever increasing shortage of PIR foam insulation boards.
This is an unprecedented shortage the like of which we have never seen before. It is one which has forced people to either plan far in advance for ordering materials. Alternatively completely where possible change the insulation they are using.
Back to the question ‘ What do you do when you can’t buy PIR insulation? ‘
The answers are you can either put your project on hold alternatively change to an insulation that is available. One such type of product is multi-foil insulation. We supply a variety of multifoil insulation products from different manufacturers such as Actis with their range of Triso and Hybrid / Hybris insulation foil insulation. Also Superfoil insulations multifoil range is available within a few days of ordering.
Both of these insulation suppliers provide a wide range of multi foil products. These can be used on their own and along side other types of insulation to replace PIR insulation. Actis have a great online calculator that shows what products of theirs are required to hit you target ‘u’ value.
Another range of products that can be used to replace PIR insulation can be mineral wool and glass wool insulation materials. These can be used where space is not limited to fit the materials in. These types of insulation tend to be somewhere near half the insulation value of the equivalent thickness rigid insulation board. You do need to use a lot thicker insulation or further insulation in different parts of your construction.
