The Insulation Handbook A guide to comfortable energy efficient buildings
Introduction Our vision to lead the UK mineral wool market in energy efficiency and acoustic insulation solutions will be achieved with products that meet the highest thermal, acoustic and fire safety performance levels. We will meet changing regulations first and surpass current regulations for those that wish to excel. Our products will provide best value solutions for the new build, renovation and technical building environments, be safe to use and help to protect the environment. Our insulation handbook is a quick reference guide to ensure you chose the right insulation solution for the job. The guide leads you through solutions for external, separating and internal construction elements and is split into two sections – Applications and Products.

Airtightness and Moisture Control Vario Membrane System is an intelligent membrane, designed to adapt to the climate and protect your building, inside and out. It’s also designed with an uncompromising commitment to superior airtightness. Vario Membrane System will improve your BER (building energy rating), save money, increase comfort and help to combat climate change. Vario meets and exceeds industry standards, while making a substantial contribution to your BER and environmental footprint. Developed in Germany and available exclusively from Isover, Vario membrane is as sophisticated as human skin – altering its structure according to relative humidity. Vario vapour control membrane offers superior performance, facilitating the drying of the building structure whilst delivering superior levels of airtightness within the building envelope. Just how good is it? Vario’s performance is truly outstanding, it has an excellent variable sd-value: it diffuses 25 times more moisture in summer than the structure absorbs during winter.
How does the Vario System work? Vario’s most unique quality is its ability to change its water vapour performance. The Vario membrane adapts and reacts naturally, changing its permeability according to humidity conditions, allowing closed building systems to increase their drying potential. This means Vario is truly multifunctional: acting as a barrier in winter and a breathable membrane in summer.
In Summer
In Winter
As the structure warms in summer, the membrane’s micropores open, allowing vapour to escape into the building interior.
In winter, the membrane prevents vapour from the warm interior diffusing into the timber structure.
Vario can be used in a diverse range of conditions:
Isover Products:
www.isover.co.uk
Masonry Buildings
Steel Frame Buildings
On roofs, walls, windows and doors, sealing up any openings or penetrations in the building envelope where heat might be lost.
On roofs, windows, doors and also to seal up any opening or penetrations in the building (such as vents for tumble dryers) where heat can be lost.
In steel frame structures such as commercial and retail buildings, Vario can be used in the same applications as on timber frame structures, except tapes are used instead of staples.
