Stone Wool Insulation

stone wool insulation installation

Stone wool insulation is a unique and highly versatile product. Its exceptional thermal properties have contributed massively to European efforts to save energy, in turn combatting climate change. In addition to energy saving efforts, it has contributed to noise pollution, both in residential and industrial settings. This is due to the makeup of stone wool insulation – it is a mat of mineral fibres woven together that prevents air movement. It also has a high thermal resistance, contributing to the reduction of home and industrial fires over recent years.

The success of stone wool has led it to be used in a variety of different applications and situations. It is a common choice for home cavity wall insulation, loft insulation, and underfloor insulation. It’s inherent properties and long lifespan make it an ideal choice for a near-permanent solution to any home insulation problem.

What Is Stone Wool Insulation?

Stone wool is the general name for fibrous materials that are formed by spinning or drawing molten minerals into strands of fibre. The resulting fibres have a combination of physical properties that no other insulative material can match.

Stone Wool Insulation

Inorganic rock or slag are the main components – typically in the region of 98% - of stone wool insulation. The remaining ~2% organic content is generally some form of thermosetting resign binder, an adhesive used to make the stone wool insulation more cohesive, and a little oil.

Stone wool insulation is commonly formed form volcanic rock, often basalt or dolomite, of which an increasing portion is recycled material in the form of briquettes. Not only is it, by its very nature, naturally renewable and sustainable, it boasts a unique combination of physical properties that result in a multitude of benefits for insulative materials.

Features of stone wool:

  • Stone wool insulation has excellent thermal insulation, reducing energy consumption in the winter and helping preventing your home from overheating in the summer.

  • Stone wool comes in rolls that can be unrolled between joists, making it relatively easy to install (not as easy as glass wool).

  • Stone wool has superior fire resistance when compared to glass wool; installing it can actually improve the fire resistance of your property, effectively acting as a fire barrier.

  • Stone wool is about 4 times denser than glass wool, so has better acoustic properties.

  • Stone wool is costs approximately £5/m2.

ROCKWOOL Insulation

ROCKWOOL Cavity Wall Insulation

With timber frame fast becoming the preferred method of home construction due to the attached costs and relatively quick building times, extra care must be taken to ensure an appropriate level of fire safety. This is where ROCKWOOL stone wool insulation steps in; perfect for use in cavity wall insulation, underfloor insulation, or loft space insulation, ROCKWOOL has the necessary thermal resistance to reduce the risk of fire in a home setting.

The speed, simplicity, and accuracy that comes with a ROCKWOOL installation also make it perfect for home insulation installations. The stone wool insulation slabs fit tightly into the studies, leaving no gaps for loss of heat or allowing for the escape of any 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.

ROCKWOOL Loft Insulation

Another large area of application for ROCKWOOL stone wool insulation is loft insulation. 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.

Testimonials.

“Outstanding service”

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.
