HardiePlank Cladding in Alton – Sail Cloth External Wall Insulation Project

Location: Alton, Hampshire

Service: External Wall Insulation & HardiePlank Cladding Installation

Project Overview

We recently completed this HardiePlank cladding project in Alton, with the customer choosing cladding primarily as a way to incorporate external wall insulation and improve the property’s exterior.

The installation included 25mm Celotex insulation, a waterproof membrane and timber battens before the property was finished with HardiePlank cladding in Sail Cloth.

This provided the customer with the added insulation they were looking for while also giving the exterior of the property a smart, low-maintenance new finish.

Why the Client Chose Cladding

  • The main aim of the project was to add external wall insulation to the property.
  • A 25mm Celotex insulation layer was incorporated behind the new cladding system.
  • HardiePlank provided a durable and low-maintenance exterior finish over the insulated wall.
  • Sail Cloth was selected to give the property a clean, traditional appearance.

Job Details and Specifications

  • New Cladding Installed: HardiePlank
  • Colour/Finish: Sail Cloth
  • External Wall Insulation: 25mm Celotex
  • Battens: 25mm timber battens
  • Weatherproofing: Waterproof membrane
  • Finishing Details: Colour-coded profiles and white window extenders
  • Location: Residential property in Alton, Hampshire

Benefits of External Wall Insulation & HardiePlank Cladding

  • Added Insulation: The insulation layer helps improve the thermal performance of the external wall.
  • Weather Protection: The complete cladding system provides a durable external finish.
  • Low Maintenance: Fibre cement cladding requires considerably less maintenance than traditional timber.
  • Attractive Finish: HardiePlank in Sail Cloth gives the property a clean and timeless weatherboard appearance.

Project Outcome

The finished installation achieved the customer’s main objective of adding external wall insulation while also transforming the appearance of the property.

With 25mm Celotex installed behind the new HardiePlank cladding, the customer benefits from an upgraded external wall build-up as well as a smart new exterior. The Sail Cloth finish gives the property a clean appearance that works particularly well with the existing white detailing.

The whole process was superb from contacting Jack in the office who booked an appointment for me with Simon who gave me all the information I needed plus price in a friendly and professional way and after discussing it with my wife we went ahead and ordered the hardie lap cladding in soft green plus insulation!!!!!! The installation team Adam and Rich were first class and nothing was too much trouble for them and were definitely customer focused and orientated and very pleasant,polite and friendly and did the job efficiently and quickly with no fuss and tidied up as they went and did such a good job of it that you would be hard put( except for the cladding!!!!) to know that we had anything done!!!!! I would recommend the gutter and cladding company to anyone!!!! Well done the whole team!!!!!👍

Having seen the first rate job done by The Gutter and Cladding Company on one of our neighbours property we decide to use them to replace our old and tired cladding. We were not disappointed. From the onset we were treated with courtesy. Everything was fully explained – the different types of cladding, the insulation and the fitting procedure. As we were unsure of which colour cladding to have, photos of the house with the different colour cladding superimposed on it were sent to us. This was a tremendous help. The fitting crew were very competent, polite and professional answering our questions and queries in a knowledgable and well mannered way. The work was carried out to a very high standard and any mess was cleaned up as they went along. We received phone calls and texts from head office checking that we were happy and keeping us up to date with any changes. Overall it was a thoroughly professional job with a lovely end result. I am more than happy to recommend this company.
