Give your home the insulation it needs

Wall insulation will reduce your heating bills and add comfort to your home, keeping the heat in during the winter and keeping you cool when the sun comes out. Our range of wall insulation can give you the ideal insulation for your property.

Insulation from the market leaders

In general the insulation is done internally if it is retrofitted, or within the brick courses if it is a new build. The main products for retrofitting insulation on walls are made by the three biggest suppliers Kingspan, Celotex and British Gypsum.

At Planet Insulation, we offer a range of products from these market leaders at great prices and delivered when you need it.

Deciding On A Home Insulation Product

Your choice is often arrived at by weighing up the merits of space lost and the price of the boards. The better the performance of the insulation materials the higher the price is the general rule. Here are some other factors to think about.

Which type of wall insulation?

The majority of boards come in two varieties; those backed with plasterboard and those not.

  • Normal Thermal Boards

    These are foil backed on both sides and are by far and away the most popular selling. The Celotex GA4000 range and Kingspan TP10 range are to all intents, indistinguishable, from a thermal performance perspective. The new regulations have meant that greater and greater thickness are now required to achieve the required U value. For walls this is likely to be in the region of 70mm of insulation but this is very much dependent on the wall construction (i.e. brick or block cavity or non cavity)

  • Plasterboard Backed

    These inlcude the Kingspan K17 & K18, Thermaline Boards and Celotex Pl Range. If you select a plasterboard backed product to go on your wall the main factors to think about are "How am I going to fit the product?" and "How thermally efficient is the product?". Where the choice is to mechanically fix, this is typically achieved by screwing through the insulation, either into battens or direct into the party wall. Screwing into battens is the preferred method as it easier to do and provides a more stable fixing.

Fixing Choices

You can either fix mechanically with screws or you can dot and dab (glue) the product with dry wall adhesive:

  • Gyproc Thermaline Basic

    With the Gyproc Thermaline range you can dot and dab or mechanically fix the whole range giving options.

  • Kingspan K18 & K17

    Kingspan have divided their boards between mechanical fix Kingspan K18 and Dot and Dab Kingspan K17.

  • Celotex PL4000

    Celotex provides a PL4000 board which can be glued or screwed so you can choose which method is used.

Dot and Dabbing is the term used to describe putting dollops of adhesive on the wall and pushing the boards into place. Screwing to battons also adds an air gap which is necessary where damp may be a issue, with a 25mm air gap is typically required.

Thermal Efficiency

Key to making the right board choice is understanding thermal efficiency of boards. Boards use different insulants which perform differently. These range from lower efficiency expanded polystyrene to high efficiency phenolic foam. The better the efficiency the more you pay; and the thinner the product is, therefore the less space you lose for the same amount of insulation.
