ROCKWOOL Insulation is part of a ground-breaking development in the insulation industry: insulative material spun from volcanic diabase rock, known as mineral wool. The resulting material is heat resistant, moisture resistant, breathable, delivers a high thermal insulation, provides sound protection, and is structurally sound. To say that there has not been an insulative material like it would be a gross understatement.
Stone wool insulation is made from one of nature’s most abundant resources – volcanic rock. Not only is it naturally renewable and sustainable, it also boasts a unique combination of physical properties that result in a plethora of benefits for insulative materials. Every ROCKWOOL product possesses outstanding fire, acoustic, and thermal insulation properties, as well as lifelong durability. This makes it the sustainable and cost-effective choice for insulation solutions.
ROCKWOOL stone wool insulation shields buildings and their occupants, improving safety, comfort and building value. The World Health Organisation has left stone mineral wool off its list of potential carcinogens following long-term studies. After more than 60 years in use, ROCKWOOL insulation has proven to be the safe and most durable choice.
Timber framed are fast becoming a popular choice for homes due to the speed of construction and flexibility in terms of finish options. Timber frame solutions offer the flexibility to increase the levels of insulation in a home while still retaining the same look and feel as traditional masonry cavity walls. They have also been proven to last just as long as traditional masonry walls.
ROCKWOOL stone wool insulation is a cavity wall insulation material well suited to timber frame structures due to the quick, easy, and accurate fitting and installation. The stone wool slabs fit tightly into the studs, leading no gaps for loss of heat or the escape of sound.
The high dimensional stability of the ROCKWOOL slabs also means they stay in place for the lifetime of the building, even as timbers continue to dry out and contract after construction.
Lastly – and arguably most importantly with regards to timber frames – in the ROCKWOOL insulation’s ability to resist fire, with a fire resistance of over 1000oC.
ROCKWOOL FLEXI® is a multi-use, dual purpose (thermal and acoustic) insulation product with a unique flexible edge along one side. The patented flexible edge ensures a perfect fit is maintained between the product and its supporting framework for ease of installation and optimum effectiveness as an insulation material.
Patented ‘Flexi’ edge offers accurate fit to all widths
Will not slump, even if studs shrink
Fits all typical metal and timber frame spacing

ROCKWOOL can be used to provide solutions for application at the ceiling line – ideal for residential buildings where the loft space does not need to be habitable. Insulation can either be supplied by ROCKWOOL insulation rolls or by blown fibres. Both solutions are a great improvement for the thermal efficiency of a building, making them ideal for loft insulation.
ROCKWOOL Roll, Twin Roll and Rollbatt products provide effective, medium density thermal insulation with acoustic properties and fire resistance. The products are suitable for roof spaces in all types of buildings or to overlay ceiling tiles in suspended ceilings. ROCKWOOL Roll consists of a single 1200mm width roll, TwinRoll consists of 2 x 100mm thick layers in a pack, pre-split to deliver two thickness application options, and Rollbatt is pre-cut insulation rolls, in either 400mm or 600mm widths.

Heat resistant. Due to the physical properties of ROCKWOOL, it is able to withstand temperatures up to 1000oC. This increases the fire safety of any premise that it is installed in, providing extra protection in the event of a fire.
Moisture resistant. Thanks to water repellent additives, ROCKWOOL repels moisture, making it difficult for rot and mould to gain a foothold in the insulation. This reduces the chances of structural damage and potential health hazards in the home. It also ensures that ROCKWOOL has a longer lifespan in the event of unexpected exposure to water.
Breathable. ROCKWOOL is porous, allowing homes to breathe and function as they should.
High thermal insulation. The setting of the rock traps pockets of air, meaning ROCKWOOL delivers excellent thermal properties.
Noise resistant. Thanks to the dense nature of ROCKWOOL insulation, it has excellent sound dampening properties. This works both ways, making your home a more comfortable living environment, and reducing the amount of noise that escapes into your surroundings.
Structurally sound. Thanks to the water resistance and its naturally dense character, ROCKWOOL has been shown to be structurally sound over a long lifespan, removing any worry of structural damage in your home due to compromised insulation from your mind.
Contacted DMS Installations when my boiler packed in. Can not fault the service from start to finish and I'm amazed how quickly my problem was resolved. They sent an engineer out to my house straight away to give me quotes for a new boiler then within three days I now have a new combi boiler fitted!! Which means hot water and working radiators woo hoo!! Would recommend this company to anyone.
Highly knowledgeable and helpful, guided me through the options at length. I was guided to a Renewable solution that pays for itself through RHI / FIT and my bills are down £165 a month. Thanks!
The staff were all very helpful and friendly. I now have the kitchen I wanted. Thank you DMS. The workmen were great guys. I already recommended them to my mate
My mother had her insulation and boiler upgraded, the workman team that did the work were outstanding and very professional> I would gladly reccomend "DMS Installations"
