Common Questions About the Boost’r Hybrid Roof Insulation Roll & Breather Membrane

How do you install this multifoil insulation?

The Boost’r Hybrid Roof Multifoil Insulation Roll is designed for use on the cold side of the building fabric in roofs. It can be used in conjunction with any type of insulation.  For more information on installation, please reference the installation guide.

What is the R Value?

The R value is given to insulating material to measure it’s thermal resistance. In general terms, the higher the R Value, the better the insulation, dependant on insulation type, thickness, and density.

What is the U Value?

U-Value is a calculation that measures the rate at which heat flows through one square foot of the material. It identifies how well an insulating product prevents heat from escaping so in simple terms, the lower the U-Value, the better the insulating product is at reducing the heat transfer.

What is multifoil insulation?

Multifoil insulation is an insulation product comprised of multiple layers of sheets, foils, and insulating materials.

All of the Actis thin multifoil insulation products are made up of multi-layered reflective films sewn with foams to create thin insulation blankets.

What is a breather membrane?

A breather membrane is a sheet of material that allows water vapour to pass through from the inside of your roof or walls easily and prevents moisture or any kind of surface water from coming into the interior space or roof.

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.

On the rare occasion that an item is delivered faulty or damaged, we will exchange it or provide a refund. We must be notified by email as soon as possible and may require images. To avoid such an issue, we ask that customers do not sign for damaged goods.
