Common Questions About This Insulation Board

How Do I Install This Insulation Board?

This insulation board is suitable for varying applications including: External masonry, wall frames with insulating sheathing and internal dry lining with insulation between the framework. When installing the TW55 between timbers, a vapour control layer should also be fitted. For guidance, refer to the Thermawall brochure above.

What is This Insulation Board Made From?

The TW55 is faced on both sides with a low emissivity composite foil which has been autohesively bonded to a high-performance fibre-free rigid thermoset polyisocyanurate insulation core. This core has been manufactured with a blowing agent that has zero ODP (Ozone Depletion Potential) and a low GWP (Global Warming Potential). What all this means is that the board is highly durable and possess an indefinite lifespan when installed correctly*.

What is Thermal Conductivity?

Thermal conductivity is a term used to define how well a material deals with the transfer of heat, normally measured in watts per meter-kelvin sometimes known as the K-Value. Usually used in association with a materials U-Value (thermal transmittance) which is a more designated term for the thermal performance. Generally speaking, the lower the value the better the material is at reducing the transfer of heat. For context, the thermal conductivity of normal brick quoted at a density of 1710kg/m³ will likely be around 0.77 W/mK.

Delivery Information

We understand that ordering products online can be daunting, especially when ordering roofing materials. It is for this reason that we make our delivery processes as simple as possible for you. However, there are a few things to know about our delivery processes. These include:

  • When placing an order, you’ll see a breakdown of your delivery charge in your shopping cart. These charges are for the UK mainland only, and additional charges may apply for Northern Ireland, the Scottish Highlands and other regions.

  • Deliveries only take place on working days (Mon - Fri) and do not take place on Bank Holidays. 

  • You’ll find an estimated delivery on the majority of product pages below the 'Add to Basket' button. Whilst we aim to deliver your items within the estimated delivery, it is only an estimate. 

  • You're able to select a preferred delivery date in your shopping basket. Whilst we aim to deliver your items on this date, it is not guaranteed.
  • Orders placed after 12pm, during the weekend, and on a bank holiday will not be processed until the next working day. Please consider this when placing your order as it may impact your delivery date.

  • After you’ve placed your order, you’ll receive an order confirmation by email outlining the details of your order. Please check your order confirmation email and inform us of any mistakes or errors immediately.

  • Shortly after receiving your order confirmation you’ll receive a separate email confirming the planned delivery date.

  • We can only provide a delivery date and are not able to confirm the time delivery will be attempted. Therefore, we ask that somebody is able to accept and sign for your items throughout the started delivery date.

  • If you are unable to accept and sign for an order, it can be left in a safe location in most circumstances. Please email [email protected] if you would like an item to be left without a signature. 

  • Whilst we aim to hold the majority of our products in stock, due to the vast number of products we offer this is not always possible. Because of this we are required to send your items directly from the manufacturer on a small number of occasions, at which point a different delivery charge may apply as standard.  

  • On occasions the items ordered may be shipped from different depots, which could result in seperate deliveries taking place.

If you have more questions about our products or delivery, please contact our team online or by telephone.
