How long does external insulation last?

External and solid wall insulation has a life expectancy of 30 years plus.

Can you paint external insulation?

When you paint your EWI, you should use a silicone-based paint or a breathable organic paint rather than an acrylic based one. When you fix lightweight fixtures such as lights or hanging baskets, it is usually only necessary to use a spiral anchor fixing, which helps the screw bite into the insulation.

Does external wall insulation stop damp?

In summary, external wall insulation can prevent future damp on walls from condensation but it won’t mask existing problems of water penetration. If you have burst guttering, roof problems or rising damp, make sure you get those items repaired at the same time, or prior to the insulation being installed on the walls.

Does solid wall insulation cause damp?

Does external wall insulation cause mould? Buildings need good ventilation in order to preserve indoor air quality and also to prevent condensation, which can lead to damp in the long run. A good external wall insulation installer will leave gaps around air vents and use breathable render.

Is it better to insulate inside or outside?

Interior insulation is cost effective, but can reduce usable space and doesn’t protect against water. Exterior insulation is expensive and susceptible to insects. Regardless of the insulation choice, efficiency, toxicity and resiliency must all be taken into account as well.

Is it worth getting external wall insulation?

Is external wall insulation worth the cost? Considering the impact of cost savings from fuel bills, the value added to your home and the difference it will make to the environment and your carbon footprint, EWI is well worth it. Your house will be more energy efficient, feel warmer and look great!

How efficient is external wall insulation?

We normally look at about a 35% energy saving if all the external walls are insulated. External wall insulation also improves the wall’s ability to withstand the elements. The insulation will cover cracks, or any poor rendering– in fact in many cases it improves the external appearance of the property.

Is it better to insulate walls from outside or inside?

From a functional point of view, external insulation can achieve higher levels of insulation with little risk of moisture problems either internally or within the wall structure, assuming it is correctly installed. It also maintains the thermal mass of the building by keeping the masonry within the insulation envelope.

How thick should external wall insulation be?

between 50 and 100mm
The thickness of the insulation needs to be between 50 and 100mm and is usually installed where there are severe heating problems or the exterior of the building requires some form of other repair work providing the opportunity of adding insulation.

What is the best way to insulate exterior walls?

One way to insulate walls of an old house is to focus on the home’s exterior:

1. Apply a house wrap/vapor barrier to exterior walls.
2. Attach 1-inch foam board insulation.
3. Install siding over the insulation.
4. Replace old windows with energy-efficient units.
5. Caulk window trim and use weatherstripping to reduce air leaks.

Do you need planning permission for external wall insulation?

Does external wall insulation require planning permission? EWI is considered ‘permitted development’ so typically does not require planning permission. However, if you live in a listed building or a conservation area then you may need planning permission to get EWI installed.

When did Everwarm start to install wall insulation?

What is an exterior insulation finishing system ( EIFS )?

What is EIFS / ETICS? An Exterior Insulation Finishing System (EIFS), also known as EWI (Exterior Wall Insulation Systems) or External Thermal Insulation Composite Systems (ETICS) is a type of cladding system that provides exterior walls with an insulated finished surface and waterproofing in an integrated composite material system.

What are the issues with external wall insulation?

Important issues when specifying an external wall insulation solution include the level of thermal performance to be achieved, which finish is the most suitable and the Reaction to Fire classification of the insulation.

How does solid wall insulation improve thermal efficiency?

We provide solid wall insulation (SWI) services to improve thermal efficiency while cutting utility bills for residents. Providing our clients with a technical solution regardless of property type, we offer both external and internal wall insulation.
