VP400 Protect Roof Membrane 1.0x50m

VP400 Protect Membrane is a highly vapour permeable roof underlay. It offers the lowest vapour resistance of any Type LR roofing underlay in its class, and yet it remains completely airtight. It is suitable for use in all pitched roofs. As the airtightness of buildings and dwellings continues to improve due to better workmanship and new practices, it is ill advised to allow uncontrolled air movement within the structure, including through a roof underlay in roofs with no vapour control or air barrier layers. One of the primary functions of roof underlays is to help manage the wind load pressures on the roof. In order to achieve this the underlay should have enough mechanical properties to be able to deflect the wind load pressures safely over the structure. Another essential property is that the underlay be water and airtight. Air permeable underlays allow air to seep through the membrane making it much more difficult to withstand the maximum wind load pressures and driving rain without other surface treatments.

Features & Benefits

• Highly vapour permeable, but completely airtight.

DELIVERY AND RETURNS

MGM have 3 different delivery methods, branch delivery, delivered to order and supplier direct. Each of these options carries different charges and restrictions.

 

Branch Delivery 

Branch delivery involves MGM delivering goods from their own stock directly to your desired address. MGM Timber operate a delivery service out of all their branches. 

We aim to deliver all orders within 1-2 working days in most areas but certain postcodes will result in higher lead times and in some cases increased delivery charges. When shopping online, once your postcode has been added, the basket page will automatically calculate your estimated delivery lead times and charges.

Please contact us before ordering if you are concerned about delivery timescales or have concerns about delivery process e.g. difficult access, weight restrictions. Please note, someone must be at the delivery address to receive the order and all orders are kerbside only!

For information on Click & Collect at your local branch please click here

What does it cost?

For most areas, our delivery charge is £20 (ex-VAT). If your order is over the value of £300 (ex-VAT) it will qualify for FREE delivery.

For some more remote areas, we have a minimum order value, higher delivery fee and / or free delivery threshold.  We regularly review these and try to keep them as low as possible. 

To see the delivery cost for your address, please build your order in the basket and add your postcode.  

For trade customer (cash or credit) branch delivery is free. However, if your basket also contains delivered to order or supplier direct products, an additional charge may be applied.

What happens after I place an order?

You will receive an email confirming your order, then your local branch will contact you within one working day to arrange your delivery and agree a specific date.
What happens on the day of the delivery?

Deliveries are to the kerbside ONLY. This means that we cannot come into your house with any product ordered. Please ensure you have the necessary ability and equipment (if required) to move the items into your property or to help unload if necessary.

If your delivery address has any access, vehicle size & weight or time of day access restrictions please let us know as soon as you have placed your order.

For our Terms & Conditions relating to Deliveries please see the section 3 of our Ecommerce Terms & Conditions

 

Delivered to Order

In some cases, our branches will order stock in from one of our suppliers to accommodate your order. While we try and deliver these orders within the same lead times stated above, in some cases there may be additional delays from the supplier in delivering your goods to us. Your branch will always contact you to inform you of any changes.

Delivered to order products are only available in the same areas of Scotland covered by branch delivery.

When products are ordered in from our suppliers, there may be an additional delivery cost that will be passed on to you at the point of order. Please see the table below for more information.
