DFM acoustic insulation slabs are an essential soundproofing material to increase the airborne sound insulation performance of walls, floors and ceilings. Because of its mass, density and sound absorption properties, acoustic insulation is used in soundproof systems inside ceiling cavities, stud walls and floor joists. Available in various thicknesses and densities, we recommend using the 60kg slabs for their acoustic performance.

Size: 1200mm x 600mm x 100mm density range between 45kg/m³-140kg/m³

Fitting DFM

A good understanding of DIY is all you need to install our DFM slabs in your home. You can cut them to size with a hand saw or sharp knife. We recommend cutting them slightly larger than your opening to allow a friction fit.

The DFM range comes with a choice of density; this is how compact the slab is (not the weight). The range in density is kg/m³ from 45, 60, 80, 100 and 140. The easiest way to understand which one to choose would be to assume the higher the density, the better the overall level of soundproofing.

We recommend the 60kg/m³ as this offers the best sound insulation for the money spent. If you want to discuss the best solution for your space, don’t hesitate to get in touch.

Need help with your soundproofing call 01423 339163, alternatively send us your enquiry. You can upload any relevant documents such as plans, drawings and pictures.

    Please call 01423 339163 if you require any of these additional services.

    How long will delivery take?

    We aim to despatch orders within 2-3 days of placing your order.

    If you order online, you will receive a confirmation email that we have received your order and it has been processed. We will then contact you once the order is just about ready to be dispatched to confirm a suitable delivery date. If you would like to discuss delivery times with us, please call 01423 339163. We recommend contacting us if you require the goods to be delivered on a specific date before placing your order.

    If you place an order over the weekend or on a Bank Holiday, this will be confirmed as an order on the first working day after the weekend or Bank Holiday.

    If you need goods in a hurry, give us a call. We carry most items in stock, which can be delivered quickly if required. Call 01423 339163.

    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 typically 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 heavy items 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 plan on leaving your goods outside, you should use additional coverage to protect them from adverse weather conditions.

    Damaged or missing items

    If 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 rectify the problem quickly.

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

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

    Returns

    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 unused materials and bring them 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.

    If you require any additional information regarding deliveries, please give us a call 01423 339163. Alternatively get in touch via our contacts page.
