Installing Noisestop Acoustic Underlay

Noisestop Acoustic Underlay

Installation of acoustic underlays can be carried out by anybody that feels they are a competent DIYer. If you don’t want to install the products yourself, we normally recommend a local carpet fitter. If you are already replacing your floors as part of the work, your floor fitting company can install your soundproof underlay.

Soundproof underlay can be loose laid over the existing floor, and there is no requirement to glue the flooring in place unless the installation is for Part E, in which case use Isobond adhesive to secure the mats to the floor.

Laying a carpet over Noisestop Acoustic Underlay

If you are using Noisestop Acoustic Underlay below carpets, you should consider whether to use a traditional carpet underlay or not. Gripper rods should be used around the perimeter of the room to hold the carpet in place. If you use the Noisestop Acoustic Underlay with an underlay, you should install the perimeter edging strips before the carpet grippers. Secure the edging strips and grippers with tacks or nails.

Installing solid floor finishes over Noisestop Acoustic Underlay

Flooring that is less than 15mm thick should be combined with a 6mm ply or MDF sheet to ensure there is no movement of the finished floor. Laminate flooring, engineered flooring should be bonded to the ply or MDF. Flooring that is thicker than 15mm can be laid directly over the mats. Consideration should be given to the possibility of sound transferring from the solid flooring to the walls, use isolation tapes against the wall to prevent flanking noise. Use Isobond adhesive to secure the mats to the floor or the resilient layer if necessary.

    How will my order be delivered?

    The majority of orders we despatch are sent on pallets. We use a network of pallet distribution companies across the UK. All our pallet deliveries are kerbside deliveries. This means the pallet will be delivered as near to the delivery address as possible. Pallets are unloaded from the vehicles with a pallet truck. If it is possible the pallets can be dropped on driveways if they are accessible with the pallet truck.

    Pallet deliveries are normally made on 7.5-tonne vehicles that are similar in size to bin lorries. Occasionally larger vehicles are used. If you know of any reason why it might be difficult to deliver to your address with this type of vehicle, please let us know so we can pass the information on to the delivery company. Typical delivery problems can include parking restrictions, access issues for certain size vehicles, low bridges and overhanging trees. Call 01423 339163 if you are unsure.

    Unfortunately, the delivery drivers will not bring the goods into your property or unload the individual items from the pallets.

    Many of our items are heavy and often require two people to carry them safely.

    All orders sent on pallets are wrapped and secured to the pallet to protect them while in transit. Once you have received your order, we would recommend storing the materials inside. If you are planning on leaving your goods outside, you should use additional coverage to protect them from any adverse weather conditions.

    Damaged or missing items

    In the unfortunate event that items are damaged or missing when your order arrives, you should sign damaged or missing items on the driver’s paperwork. Call 01423339163 to let us know of the issue to allow us to quickly rectify the problem.

    We might ask for a picture of the damage; this is to speed up the process of arranging a suitable solution.

    To enable us to resolve any issues with your delivery it is important that you sign for your delivery when it arrives.


    Can I return items from my order? Yes, you can return unused items from your order that are in a salable condition. We can arrange to collect any unused materials and have them brought back to us. We would refund the cost of the items returned back to us less the shipping cost incurred by the company collecting the items. The cost to return the goods would be confirmed at the point of arranging the return. The refund would be paid once the goods have been brought back and have been checked at our warehouse.

    Alternatively, you can arrange to return the materials back to us, and we will issue a refund once they have been received.

    *All prices displayed are exclusive of VAT @ 20%. This will be added at the end of the checkout process before you confirm your order.
