Insulating your home is very important particularly with the weather in the UK and Ireland. It acts as a barrier against cold in the winter and disperses excess heat in the summer. In addition to keeping the optimum desired temperature all year round it will help to reduce noise pollution and energy bills. A well-insulated home is very energy efficient and vital, this is a key factor for two reasons;
- If buying/building a property for yourself, sufficient insulation will dramatically reduce your energy costs
- If you are a property developer looking to build in order to rent, as of April 2018 in the UK you cannot rent out any property with an energy rating (EPC) of F or G.
You can have the walls, roof, windows, floors and even your doors insulated, but the main area to insulate would be the walls as they can lose around 30-40% of the heat. The roof would be the next most important area to insulate losing around 25% of heat. Next the windows and doors losing around 15% as well as the floor.
It’s also essential to choose the right type of insulation that will do a great job in conjunction with not taking up too much space. See comparison chart below for the thickness required to reach the insulation effect with different materials.
Here at Tempohousing we use a variety of insulation types. For example, some of our projects involve recycling and refurbishing used shipping containers. Our standard 40 ft shipping containers are 2.4 wide x 12-meter-long providing a surface of about 30m2. We want to maximise the amount of space whilst also providing great insulation. For our Keetwonen project comprised of 1034 units we used XPS which you can see from the chart requires very minimal thickness to achieve optimum insulation. It also has many benefits such as its inability to absorb moisture resulting in a less favourable environment for mould growth and it acts as a barrier against moisture. XPS retains its insulating properties over time meaning there will be no slow rising heating costs and it is also e recyclable product. Also the balance between required material, thickness, costs and the fact that it’s recyclable make it a good material to insulate properly with thin insulation panels.
For our student accommodation project in Utrecht “Place2BU” comprised of 255 units making up 490 apartments we used a combination of PIR and rockwool insulation for the modules. Again, you can see from the chart that a minimal thickness is required for optimum insulation here particularly with the PIR product. PIR boasts a wealth of benefits such as;
- It has an extremely low lambda value of 0.022.
- It is super light weight which is a great advantage for transporting the modules.
- It does not absorb any moisture subsequently maintaining its original weight and insulation value as well as eliminating mould growth.
- One of the most important points about PIR is its compliance with fire regulations. It produces a very minimal amount of smoke and gases and does not melt or drip. The fire rating for PIR is B, S2, d0 which is very high and really safe to use in a building.
Rockwool is slightly higher on the thickness chart but not high enough to make a significant effect on overall internal space. In terms of fire safety this material is excellent as it can withstand more than 1000°C without melting meaning it can slow the spread of fire. It also has great acoustic insulating properties delivering great sound reduction, perfect for properties near busy roads or train stations.
