Weber insulation transforms efficiency of homes

External wall insulation (EWI) systems are making a difference to the thermal improvement and external redecoration of solid wall and non-traditional buildings says Weber.

Weber is a specialist in the manufacture of industrial mortar products.

Its core product range consists of external renders which include A+ Green Guide Rating monocouche renders - weber.pral M and weber.pral D - which are leading the way in EWI systems that are transforming 'hard to heat' homes.

Peterborough's 1950's homes are being modernised with a major refurbishment project already underway to bring these Cross Keys Homes closer to today's standard of thermal performance.

A key factor in this plan is the use of the weber.therm External Wall Insulation (EWI) system.

The project has benefited from GBP1m of support secured by Weber from the CERT funding initiative.

A variety of different finishes are being used with the versatile weber.therm EWI system to allow properties to keep their original character while achieving visual variety.

To date this has included weber.therm XM which uses through coloured, decorative and weather resistant render to the insulation system, while other properties have been finished with a real brick appearance in weber.therm RB.

weber.rend RB produces a brick look-alike finish in a fraction of the time and at a fraction of the cost of full brickwork cladding.

weber.rend RB is the combination of two polymer modified mortars used in conjunction to create the brick work pattern.

A real brick finish is available from Weber and can be achieved using weber.therm XB.

Insulation is fixed to the original substrate of the building followed by a basecoat render with meshcloth reinforcement.

Once set, the surface is lightly comb scratched prior to the application of the weber.rend RBB render coat which acts as the mortar joint.

When the RBB coat has taken-up"and is firm enough to allow application of the face coat, 2-3mm of weber.rend RBF is applied and stippled with a soft bristle brush to give the brick effect finish.

Eight colours of face render are available, allowing the client to replicate almost any brick and mortar combination which is particularly important when matching in with existing properties.

The brick pattern is achieved by cutting through the weber.rend RBF face coat to expose the contrasting RBB render, creating the brick pattern finish.

Any brick pattern can be achieved including conventional cavity layout as well as header and stretcher bonding of traditional solid walls.

The weber.rend RB brick effect render system, used as part of the weber.therm XM EWI system, is transforming both the aesthetics and thermal efficiency of non-traditional and solid wall homes in Peterborough.

The changes to the aesthetics of these Peterborough homes are matched by the changes in performance; householders report new levels of warmth and comfort.
