Vapour barriers are an integral component of building construction in cold climates, helping prevent walls from becoming wet during either the construction phase or their lifecycle.
Wood fibre insulation is one of the most popular breathable external insulation choices, although mineral wool and other products can also be utilized. Wood fiber comes with various finishes including silicone render and brick slip cladding options to meet all insulation requirements.
Cost
Are You Thinking About Insulating External Walls with External Wall Insulation? Before undertaking such an endeavor, there are a number of considerations. Insulated properties tend to be more attractive for buyers and renters, while cutting carbon emissions could help save on heating costs.
Keep in mind that if your property features cavity walls, additional insulation may not be required; however, always consult with the appropriate local authorities first before beginning work on any conservation areas or listed properties.
Insulating exterior walls requires careful consideration of any potential costs or disruption caused by insulation. Window sills may need to be widening to accommodate thicker insulation; or you may need to re-drill holes for fixtures and fill in areas around reveals with additional insulation – all processes which can be completed without harming internal walls of your property.
Benefits
External insulation not only reduces energy bills and raises resale values of buildings, but it can also make them more appealing to prospective buyers and tenants. By modernizing and updating its appearance, external insulation makes an entire property appear more modern and appealing – which may increase sales or rentals of the property in question.
Cladding comes in various materials, ranging from stone and brick to timber and synthetics. Usually completed with rendering that can either be smooth or textured for an ideal finish, it can also be painted, panelled or pebble-dashed before finishing off with realistic brick slips for a truly finished look.
Insulation will help reduce heat loss by raising the surface temperature, thus decreasing condensation and damp problems on walls, while creating a waterproof barrier against penetrating damp. Prior to beginning cladding process, render test will be conducted to ascertain whether existing render can support weight of insulation layer before any removal takes place; pipework must also be moved away from wall in order to avoid cold bridging issues.
Complications
Installation of external wall insulation can be more intricate than standard cavity wall installation, which is why it should only be undertaken by professional installers. There may be issues regarding fixture positioning such as radiators; in such instances it may be necessary to move or extend them if needed. Furthermore, it must ensure that any existing plumbing or gas flues do not become compromised during this process.
Gaps between insulation and windows or doors can lead to cold bridges that reduce your newly insulated home’s efficiency. A thorough survey will identify any issues in these areas and find solutions tailored specifically to your property.
Moisture may gather behind an insulated wall as warm internal air condenses onto cold exterior wall surfaces, leading to damp patches and mould growth. To reduce this possibility, make sure your quote includes waterproof rendering as a standard requirement, or consider an impermeable product such as spray foam insulation that offers more effective moisture-wicking qualities.
Safety
EWI (Exterior Wall Insulation) is an exterior wall cladding procedure which serves to thermally insulate, protect and decorate exterior cladding of homes, typically using expanded polystyrene or phenolic insulation topped by either cement based mineral render or synthetic render. There are various insulation products available and choosing one tailored to your home is key for thermal, acoustic and fire safety performance.
Installation issues can cause mould and dampness growth; block off interior doors complicating escape routes in case of fire or emergency; and cause electricity to get through to energise fibres in insulation material – but an experienced installation and rendering company will take measures to avoid these risks.
Quality external wall insulation (EWI) systems are fire retardant and tested to have a low combustion level, allowing water vapor to pass through and eventually dissipate from their structure. Furthermore, these breathable systems permit moisture vapor from entering through pores in the structure in order to evaporate out through it.
